Several promising non-pharmacological interventions have been developed to reduce acute pain in preterm infants including skin-to-skin contact between a mother and her infant. However, variability in physiological outcomes of existing studies on skin-to-skin makes it difficult to determine treatment effects of this naturalistic approach for the preterm infant. The aim of this study was to test the efficacy of mother and infant skin-to-skin contact during heel prick in premature infants.
                Fifty nine stable preterm infants (born at least 30 weeks gestational age) who were undergoing routine heel lance were randomly assigned to either 15 min of skin-to-skin contact before, during and following heel prick (n=31, treatment group), or to regular care (n=28, control group). Throughout the heel lance procedure, all infants were assessed for change in facial action (NFCS), behavioral state, crying, and heart rate.
                Statistically significant differences were noted between the treatment and control groups during the puncture, heel squeeze and the post phases of heel prick. Infants who received skin-to-skin contact were more likely to show lower NFCS scores throughout the procedure. Both groups of infants cried and showed increased heart rate during puncture and heel squeeze although changes in these measures were less for the treated infants.
                Skin-to-skin contact promoted reduction in behavioral measures and less physiological increase during procedure. It is recommended that skin-to-skin contact be used as a non-pharmacologic intervention to relieve acute pain in stable premature infants born 30 weeks gestational age or older. To investigate whether breast feeding is effective for pain relief during venepuncture in term neonates and compare any effect with that of oral glucose combined with a pacifier.
                Randomised controlled trial.
                180 term newborn infants undergoing venepuncture; 45 in each group.
                During venepuncture infants were either breast fed (group 1), held in their mother's arms without breast feeding (group 2), given 1 ml of sterile water as placebo (group 3), or given 1 ml of 30% glucose followed by pacifier (group 4). Video recordings of the procedure were assessed by two observers blinded to the purpose of the study.
                Pain related behaviours evaluated with two acute pain rating scales: the Douleur Aiguë Nouveau-né scale (range 0 to 10) and the premature infant pain profile scale (range 0 to 18).
                Median pain scores (interquartile range) for breast feeding, held in mother's arms, placebo, and 30% glucose plus pacifier groups were 1 (0-3), 10 (8.5-10), 10 (7.5-10), and 3 (0-5) with the Douleur Aiguë Nouveau-né scale and 4.5 (2.25-8), 13 (10.5-15), 12 (9-13), and 4 (1-6) with the premature infant pain profile scale. Analysis of variance showed significantly different median pain scores (P<0.0001) among the groups. There were significant reductions in both scores for the breast feeding and glucose plus pacifier groups compared with the other two groups (P<0.0001, two tailed Mann-Whitney U tests between groups). The difference in Douleur Aiguë Nouveau-né scores between breast feeding and glucose plus pacifier groups was not significant (P=0.16).
                Breast feeding effectively reduces response to pain during minor invasive procedure in term neonates. A total of 50 premature infants (25 in KC group, 25 in control group) were included in this comparative, randomized, controlled study. Gestational and postnatal ages of the infants were between 26-36 weeks and 0-28 days, respectively. Infants with congenital abnormalities or sepsis and those who needed mechanical ventilation or surgical intervention were not included in the study. None of the infants received narcotic analgesics. Behavioral and physiologic responses to pain were recorded and Premature Infant Pain Profile (PIPP) was used to evaluate the severity of pain. Collected data was evaluated using SPSS for Windows 11.5 program. Premature Infant Pain Profile scores were significantly lower at each measurement during or soon after the invasive procedure in infants in the KC group compared to controls. In conclusion, KC starting 30 minutes before and continuing 10 minutes after an invasive procedure was found to be effective in decreasing pain during and after the invasive procedure in premature infants. The aim of this randomized crossover study was to evaluate the impact of environmental and behavioral interventions (EBI) on behavioral, physiologic, and biologic stress response during a weighing procedure in neonates. Three groups of 15 neonates included (A) gestational age (GA), < or =32 weeks; (B) GA, 32 weeks, 1 day to 36 weeks, 6 days; and (C) GA, > or =37 weeks. Each neonate experienced 2 weighing procedures with and without EBI. Pain was evaluated by using the Neonatal Infant Pain Scale (NIPS) and the Neonatal Pain and Discomfort Scale (EDIN). Heart rate and oxygen saturation were recorded. Salivary samples were obtained for cortisol assay. Cerebral tissue oxygenation index (TOI) was recorded with near-infrared spectroscopy. A significant decrease of NIPS and EDIN was observed with EBI versus control. Mean heart rate was lower with EBI. No difference in cortisol level changes was observed. For groups A and B, a trend of increased TOI was observed with EBI. We concluded that EBI during a nursing procedure provides a decrease in pain scores in preterm and term neonates with changes in heart rate.
                This study evaluates the impact of combined environmental and behavioral interventions on pain responses in neonates during a weighing procedure. The results indicate a decrease in behavioral pain scores and in heart rate for preterm and term neonates and a trend in increased brain oxygenation depending on gestational age. Previous work has shown that parents prefer to be present when their children undergo common invasive procedures, although physicians are ambivalent about parental presence.
                To determine the effect of a parent-focused intervention on the pain and performance of the procedure, anxiety of parents and clinicians, and parental satisfaction with care.
                Children younger than 3 years old undergoing venipuncture, intravenous cannulation, or uretheral catheterization.
                Pediatric emergency department of Boston City Hospital.
                Randomized controlled trial with three groups; parents present and given instructions on how to help their children; parents present, but no instructions given; and parents not present.
                The parents were instructed to touch, talk to, and maintain eye contact during the procedure.
                A total of 431 parents was randomized to the intervention (N = 153), present (N = 147), and not present (N = 131) groups. The groups were equivalent with respect to measured sociodemographic variables and parents' previous experience in the pediatric emergency department. No differences emerged with respect to pain (3-point scale measured by parent and clinician, and analysis of cry); performance of the procedure (number of attempts, completion of procedure by first clinician, time); clinician anxiety; or parental satisfaction with care. Parents who were present were more likely to rate the pain of the children as extreme/severe (52%) in comparison to clinicians (15%, kappa .07, poor agreement) and were significantly less anxious than parents who were not present.
                Overall, the intervention was not effective in reducing the pain of routine procedures. Parental presence did not negatively affect performance of the procedure or increase clinician anxiety. Parents who were present were less anxious than those who were not present.
                In general, parents have indicated that they want to be present when their children undergo procedures. The results of this study challenge the traditional belief that parental presence negatively affects our ability to successfully complete procedures. We should encourage parents who want to be present to stay during procedures. This study compared the efficacy of a behavioral pain reducing intervention (facilitated tucking) with standard neonatal intensive care unit (NICU) care for decreasing procedural pain (endotracheal suctioning) in very low birthweight (VLBW) infants.
                A prospective randomized crossover design with infants as their own controls were used. The sample consisted of 40 VLBW infants, 23-32 weeks gestation, and weighing 560-1498 g with tracheal intubation. The infants were observed twice during each endotracheal suctioning experience; one suctioning was done according to normal nursery routine; another was done using facilitated tucking (the caregiver "hand-swaddling" the infant by placing a hand on the infant's head and feet while providing flexion and containment). The Premature Infant Pain Profile (PIPP) measured the infant's pain response, and severity of illness of each infant was measured by the Score for Neonatal Acute Physiology (SNAP) and the NTISS (Neonatal Therapeutic Intervention Scoring System). Repeated measures analysis of variance (RMANOVA) determined the efficacy of facilitated tucking for reducing procedural pain (PIPP) and the effects of order of intervention vs. control. Regression analyses examined the relationship of gestational age, severity of illness, and number of painful procedures to the pain response.
                There was a significant difference between the PIPP scores for tucking and nontucking positions (p = 0.001) and a nonsignificant interaction with order (p = 0.64) as well as a nonsignificant main effect for order (p = 0.46). In the regression analyses, all predictors taken together did not significantly predict PIPP scores in the tucked position (p = 0.11) or nontucked position (p = 0.57).
                Facilitated tucking is a developmentally sensitive, nonpharmacological comfort measure that can relieve procedural pain in VLBW infants. Nurses need to be increasingly aware of infant pain during daily care taking, and to use validated pain assessment instruments. Further clinical research on individual pain assessment is needed for better understanding of the quality and significance of pain for each infant, and the factors that affect pain expression. The purpose of this study was to test the effect of Yakson (i.e. a traditional Korean touching method) and non-nutritive sucking (NNS) on reducing the pain that neonates experience when undergoing the heel stick procedure for blood testing. Ninety-nine healthy neonates were recruited and assigned into three groups: Yakson (n = 33), NNS (n = 33), and control group (n = 33). Each intervention was provided to the Yakson and NNS groups from 1 min before heel stick until the completion of the heel stick. For the Yakson group, a researcher caressed the belly of a neonate with one hand while supporting the back with the other hand. For the NNS group, a pacifier packed with sterile gauze was put in the neonate's mouth. The oxygen saturation levels in the Yakson and NNS group neonates were maintained significantly better than in the control group neonates. There was no significant difference between the groups with regard to heart rate and neonatal infant pain, measured using the Neonatal Infant Pain Scale. Findings indicate that Yakson can be used during heel stick to help neonates maintain their oxygen saturation level following the procedure. This study aimed to compare the effects of mother's milk, sucrose and pacifier use to overcome pain during painful interventions to the newborns on the crying time and pain.
                Various non-pharmacological methods are used to overcome the pain associated with painful interventions with newborns.
                A prospective, randomised, controlled study involved 120 newborns in Turkey.
                The population consisted of healthy newborns hospitalised in the gynaecology clinics of Trabzon Delivery and Children's Diseases hospital between February 2007-January 2008. The newborns who had blood sampling by heel stick were divided into four groups: mother's milk, sucrose, pacifier and control groups with 30 newborns in each. Data collection was performed using an information form on the newborn characteristics, which was developed by the researchers in the light of literature, clinical IR ear thermometer ET1 for temperature measurement, OXIMAX N-65 Pulse oxymeter for oxygen saturation and heart rate and neonatal infant pain scale for the measurement of the behavioural responses of newborns. Results.  No differences were determined between the groups for heart rate and oxygen saturation in the newborns during painful interventions (p > 0·05). Sucrose followed by pacifier was the most effective method of reducing the crying time in the newborns.
                The results indicate that all three practices reduce the behavioural responses to pain at a higher rate than in the control group.
                Health care personnel should perform painful interventions to the newborns while the babies are held by their mothers and during the procedure use of sucrose should be the primary choice.
                © 2010 Blackwell Publishing Ltd. Feeding and carrying have been interventions used by caregivers throughout history in relieving distress in infants. Recent studies on the food substance sucrose have elucidated the comforting effect of the taste component of feeding while studies of rocking have examined the comforting effect of the vestibular component of carrying. The purpose of this study was to determine the effectiveness of sucrose and simulated rocking alone and in combination on diminishing pain response in preterm neonates undergoing routine heelstick procedure in the neonatal intensive care unit (NICU). Preterm infants (n = 85) between 25-34 weeks post-conceptual age (PCA) and 2-10 days postnatal age (PNA) were randomly assigned to one of four conditions for routine heelstick procedure. The conditions were (1) sucrose alone: 0.05 ml of 24% sucrose was placed on the anterior surface of the tongue just prior to the lancing of the heel; (2) simulated rocking alone: 15 min prior to and during the heelstick procedure, the infant was swaddled and put on an oscillating mattress; (3) combination of sucrose and simulated rocking; and (4) placebo: 0.05 ml sterile water administered just prior to heelstick. Physiological (heart rate) and behavioural (facial actions) responses from baseline across 90 s following heelstick were scored second-to-second. Facial actions were analysed with repeated measures MANCOVA and heart rate with repeated measures ANCOVA. Behavioural state and gestational age were covariates. The groups that received sucrose alone or in combination with simulated rocking showed less facial actions indicative of pain than the rocking alone or control group. The addition of rocking to the sucrose condition tended to further blunt the facial expression of pain, but this enhancement did not reach a significant level. Heart rate was not decreased by any intervention compared to the control condition. Although the simulated rocking did promote quiet sleep, which has been reported in earlier studies to blunt pain response, there was no difference between simulated rocking and control groups in either facial expressions indicative of pain or heart rate. The implication of these results is that sucrose, but not simulated rocking may be a means of diminishing pain from minor procedures in preterm infants. Further research is needed on the use of sucrose for more than one procedure as well as examining the contact component of natural rocking, as opposed to simulated rocking. To assess the immediate and sustained effects of Kangaroo Care on reaction to pain of premature infants.
                A controlled, within-subject randomized study, performed in a large neonatal intensive care unit. Thirty premature infants were observed with blood test stick (BT) or without the blood test stick (W) procedure, either during Kangaroo care (K) or during standard within-crib care (C). Each of the four conditions (BTK, WK, BTC, WC) was observed in four separate sessions: baseline session - 10 min; intervention (BT or W) - 2 min; posttest - 10 min and follow-up - 20 min, in crib (starting 1 h after treatment). For neurobehavioural assessment, the naturalistic observation method was adopted from the Newborn Individualized Developmental Care and Assessment Program (NIDCAP).
                During the BTK session (blood test stick with K-care), we observed a decrease in motor disorganization and extension movements and an increase in attention signs, both negative and positive. Significant neurobehavioural changes were sustained in the follow-up period after K-care in comparison to the within-crib-care intervention sessions.
                K-care, as compared to within-crib condition, led to a decrease in stressful neurobehavioural signs after BT procedures in premature infants. Painful procedures such as the BT procedure in premature infants should be performed while the infants are being held in K-care position. Crying commonly occurs in response to heel stick and adversely affects the infant's physiologic stability. Minimal crying in response to pain is desired. "Kangaroo Care," skin contact between mother and infant, reduces pain and may reduce crying in response to pain. The purpose of this pilot study was to test Kangaroo Care's effect on the preterm infant's audible and inaudible crying response to heel stick. Inaudible crying has not been previously studied. A prospective randomized cross-over study with 10 preterm infants 2-9 days old (30-32 weeks' postmenstrual age) was conducted. Infants were randomly assigned to two sequences (sequence A: day 1 heel stick in Kangaroo Care [after 30 min of prone skin contact upright between maternal breasts] and day 2 heel stick in incubator [inclined, nested and prone]; or sequence B: opposite of sequence A) was conducted. Videotapes of baseline, heel warming, heel stick, and recovery phases were scored for audible and inaudible crying times. Audible and inaudible crying times for each subject in each phase were summed and analyzed by repeated-measures analysis of variance. Subject characteristics did not differ between those in the two sequences. Crying time differed between the study phases on both days (p <or= .001). When in Kangaroo Care compared with the incubator, crying time was less during the heel stick (p = .001) and recovery (p = .01) phases, regardless of sequence. Because Kangaroo Care reduced crying in response to heel stick in medically stable preterm infants, a definitive study is merited before making recommendations. Determinants of infant pain responses are important when assessing the efficacy of analgesics. In a randomized controlled trial, 106 infants aged 2 to 6 months were positioned either supine (SUP) on the examination table or held (HLD) by a parent during routine immunization in a community pediatric office. There was no difference between the SUP and HLD infants in duration of crying, facial grimacing or visual analogue scale (VAS) pain scores. Similarly gender did not affect pain response. In contrast, 2-month-old infants displayed more pain during immunization than did 4 or 6-month-old infants. This study aims to assess the efficacy of Kangaroo Care (KC) on behavioral responses of term neonates to the pain of an intramuscular injection.
                One hundred healthy term neonates were enrolled and randomly assigned to intervention and control groups. In the intervention group, the neonate was held in KC for 10 min before the injection and remained in KC for the duration of the procedure. The primary outcome measure was the cumulative Neonatal Infant Pain Scale (NIPS) score immediately after injection.
                The cumulative NIPS score immediately after injection in the intervention group was significantly lower (p<.001) than in the control group.
                KC given before injection seems to effectively decrease pain and should be considered for minor invasive procedures in neonates. This study examined the effectiveness of non-nutritive sucking on preterm infant pain, changes in infant behaviour and frequency of abnormal physiological signals during heel stick procedures in Taiwan.
                Preterm infants' repetitive exposure to painful procedures may result in changes to brain organisation. Pain management should be a priority in neonatal care.
                Randomised control trial.
                Preterm infants (gestational age 28.9-37 weeks) were randomised to two groups: those receiving (experimental, n = 52) or not receiving non-nutritive sucking (control, n = 52) during heel stick procedures. Pain was measured before (for three minutes), during and after (during 10-minute recovery) heel stick procedures by the Premature Infant Pain Profile, changes in infant behaviour and abnormal physiological parameters. Results.  Infants in both groups had similar odds ratios for pain and moderate-to-severe pain (0.57 and 0.58, respectively), after adjusting for time effects, postconceptional age, heel stick duration, painful experiences and baseline Premature Infant Pain Profile score. The pain scores of infants with non-nutritive sucking were significantly lower than those of non-nutritive sucking infants at all eight phases of the heel stick procedures. Infants undergoing heel stick procedures in the experimental group had lower rates ratios for 'grimace' and 'hand to mouth or face' behaviours than control infants (0.73 and 0.78, respectively).
                Non-nutritive sucking effectively reduced pain, particularly mild to moderate pain and behavioural responses to pain in infants receiving heel stick procedures, suggesting that nurses can offer this intervention to relieve pain in preterm infants undergoing invasive procedures.
                Infants should be given an appropriate-sized pacifier for comfort during painful procedures. Nurses need to be informed about the effectiveness of non-nutritive sucking, its analgesic mechanisms and how to use and incorporate it into practice.
                © 2010 Blackwell Publishing Ltd. Pain is traumatic for preterm infants and can damage their CNS. We wanted to assess whether multisensorial stimulation can be analgesic and whether this effect is only due to oral glucose or sucking. We performed a randomized prospective study, using a validated acute pain rating scale to assess pain during heel-prick combined with five different procedures: (A) control, (B) 10% oral glucose plus sucking, (C) sensorial saturation (SS), (D) oral water, and (E) 10% oral glucose. SS is a multisensorial stimulation consisting of delicate tactile, vestibular, gustative, olfactory, auditory and visual stimuli. Controls did not receive any analgesia. We studied 85 heel-pricks (5 per baby) performed for routine blood samples in 17 preterm infants (28-35 weeks of gestational age). We applied in random order in each patient the five procedures described above and scored pain. SS and sucking plus oral glucose have the greater analgesic effect with respect to no intervention (p < 0.001). The effect of SS is statistically better than that of glucose plus sucking (p < 0.01). SS promotes interaction between nurse and infant and is a simple effective form of analgesia for the NICU.
                Copyright 2001 S. Karger AG, Basel Many attempts have been made to obtain safe and effective analgesia in newborns. Oral glucose-water has been found to have analgesic properties in neonates. We investigated whether other sensory stimulation added to oral glucose provided more effective analgesia than oral glucose alone. In a randomized prospective double-blind trial, we studied 120 term newborns during heel prick. The babies were divided randomly into six groups of 20, and each group was treated with a different procedure during heel prick: A) control; B) 1 mL 33% oral glucose given 2 min before the heel prick; C) sucking; D) 1 mL 33% oral glucose plus sucking; E) multisensory stimulation including 1 mL 33% oral glucose (sensorial saturation); F) multisensory stimulation without oral glucose. Sensorial saturation consisted in massage, voice, eye contact, and perfume smelling during heel prick. Each heel prick was filmed and assigned a point score according to the Douleur Aiguë du Nouveau-né (DAN) neonatal acute pain scale. Camera recording began 30 s before the heel prick, so it was impossible for the scorers to distinguish procedure A (control) from B (glucose given 2 min before), C (sucking water) from D (sucking glucose), and E (multisensory stimulation and glucose) from F (multisensory stimulation and water) from the video. Procedure E (multisensory stimulation and glucose) was found to be the most effective procedure, and the analgesia was even more effective than that produced by procedure D (sucking glucose). We conclude that sensorial saturation is an effective analgesic technique that potentiates the analgesic effect of oral sugar. It can be used for minor painful procedures on newborns. Although sucrose has been accepted as an effective analgesic agent for procedural pain in neonates, previous studies are largely in the NICU population using the procedure of heel lance. This is the first report of the effect of sucrose, pacifier or the combination thereof for the procedural pain of venipuncture in infants in the pediatric emergency department population.
                The study design was a double (sucrose) and single blind (pacifier), placebo-controlled randomized trial--factorial design carried out in a pediatric emergency department. The study population was infants, aged 0-6 months. Eighty-four patients were randomly assigned to one of four groups: a) sucrose b) sucrose & pacifier c) control d) control & pacifier. Each child received 2 ml of either 44% sucrose or sterile water, by mouth. The primary outcome measure: FLACC pain scale score change from baseline. Secondary outcome measures: crying time and heart rate change from baseline.
                Sucrose did not significantly reduce the FLACC score, crying time or heart rate. However sub-group analysis revealed that sucrose had a much greater effect in the younger groups. Pacifier use reduced FLACC score (not statistically significant), crying times (statistically significant) but not heart rate. Subgroup analysis revealed a mean crying time difference of 76.52 seconds (p < 0.0171) (0-1 month) and 123.9 seconds (p < 0.0029) (1-3 month). For subgroup age > 3 months pacifier did not have any significant effect on crying time. Age adjusted regression analysis revealed that both sucrose and pacifier had significant effects on crying time. Crying time increased with both increasing age and increasing gestational age.
                Pacifiers are inexpensive, effective analgesics and are easy to use in the PED for venipuncture in infants aged 0-3 months. The benefits of sucrose alone as an analgesic require further investigation in the older infant, but sucrose does appear to provide additional benefit when used with a pacifier in this age group.

                Randomised prospective study with validated behavioural acute pain rating scale.
                Maternity ward.
                150 term newborns undergoing venepuncture randomly assigned to one of six treatment groups: no treatment; placebo (2 ml sterile water); 2 ml 30% glucose; 2 ml 30% sucrose; a pacifier; and 2 ml 30% sucrose followed by a pacifier.
                Median (interquartile) pain scores during venepuncture were 7 (5-10) for no treatment; 7 (6-10) for placebo (sterile water); 5 (3-7) for 30% glucose; 5 (2-8) for 30% sucrose; 2 (1-4) for pacifier; and 1 (1-2) for 30% sucrose plus pacifier. Mann-Whitney U test P values for comparisons of 30% glucose, 30% sucrose, pacifier, and 30% sucrose plus pacifier versus placebo (sterile water) were 0.005, 0.01, <0.0001, and <0.0001, respectively. Differences between group median pain scores for these comparisons were 2 (95% confidence interval 1 to 4), 2 (0 to 4), 5 (4 to 7), and 6 (5 to 8), respectively. P values for comparisons of 30% glucose, 30% sucrose, and 30% sucrose plus pacifier versus pacifier were 0.0001, 0.001, and 0.06, respectively. Differences between group medians for these comparisons were 3 (2 to 5), 3 (1 to 5), and 1 (0 to 2), respectively.
                The analgesic effects of concentrated sucrose and glucose and pacifiers are clinically apparent in newborns, pacifiers being more effective than sweet solutions. The association of sucrose and pacifier showed a trend towards lower scores compared with pacifiers alone. These simple and safe interventions should be widely used for minor procedures in neonates. There is a need for a safe and effective non-pharmacological pain management method for preterm infants. The parents could be given an active role in the pain management which may help the parents to cope with the stress related to painful situations of the infant.
                To examine the effectiveness of a method called 'facilitated tucking by parents' (a parent holds the infant in a flexed position) in pain management during endotracheal/pharyngeal suctioning of preterm infants. In addition, the parental perception of the method was studied.
                A randomized crossover trial.
                Twenty preterm infants with one of their parents participated in the study. Infants' gestational age ranged from 24 to 33 (median 28) weeks and postnatal age from 6 to 37 days (median 15 days).
                The primary outcome was the Neonatal Infant Pain Scale (NIPS) score. Heart rate and oxygen saturation were recorded. Parents completed a questionnaire about their perception of the procedure.
                The highest NIPS score was median 3 (range from 2 to 6) using 'facilitated tucking by parents' and median 5 (range from 2 to 7) without tucking during suctioning (p < 0.001). The infants calmed down more quickly after 'facilitated tucking by parents' (5 s vs. 17 s, p = 0.024). Nineteen out of twenty parents preferred facilitated tucking during suctioning compared to control care.
                Facilitated tucking by parents is an effective and safe pain management method during suctioning of preterm infants. This study shows that parents can be given an active role in the pain care of their preterm infants. This experiment had three goals: 1. To identify the basis of sucking-induced analgesia in healthy, term, newborn humans undergoing the painful, routine, procedure of heel lance and blood collection. 2. To evaluate how taste-induced and sucking-induced analgesias combine to combat pain. 3. To determine whether facial grimacing was an accurate index of diminished pain, or whether it was linked to tissue trauma. We report that: 1. Sucking an unflavored pacifier was analgesic when and only when suck rate exceeded 30 sucks/min. 2. The combination of sucrose and nonnutritive sucking was remarkably analgesic; we saw no behavioral indication in nine of the ten infants that the heel lance had even occurred. 3. Grimacing was reduced to almost naught by procedures that essentially eliminated crying and markedly reduced heart rate during the blood harvesting procedure. To identify the effectiveness of "facilitated tucking," a nonpharmacologic nursing intervention, as a comfort measure in modulating preterm neonates' physiologic and behavioral responses to minor pain.
                Prospective, repeated measure, random sequencing, and experimental.
                Level III neonatal intensive-care unit of a tertiary care university pediatric hospital.
                Thirty preterm neonates, 25-35 weeks gestation.
                Heart rate, oxygen saturation, and sleep state were recorded 12 minutes before, during, and 15 minutes after two heelsticks, one with and one without facilitated tucking.
                Premature neonates will have less variation in heart rate and hemoglobin oxygen saturation, shorter crying and sleep disruption times, and less fluctuation in sleep states in response to the painful stimulus of a heelstick with facilitated tucking than without.
                Neonates demonstrated a lower mean heart rate 6-10 minutes post-stick (p < 0.04), shorter mean crying time (p < 0.001), shorter mean sleep disruption time (p < 0.001), and fewer sleep-state changes (p = 0.003) after heelstick with facilitated tucking than without.
                Facilitated tucking is an effective comfort measure in attenuating premature neonates' psychologic and behavioral responses to minor pain. To determine the effects of a postural support protocol on the physiological and behavioral stability of preterm infants while undergoing a diaper change.
                Forty-seven newborns having a birth weight <or=2000 g and gestational age <or=35 weeks were included in this randomized, crossover clinical trial in a Neonatology Intensive Care Unit. The infants were observed as his or her own control and evaluated with and without the use of the proposed intervention, which was positioning the baby in a nest produced with rolled-up towels. During the observations, as control, the care model used by the unit was considered.
                All babies displayed increased distress and pain scores during diaper changes. This was significantly less for babies nested compared with non-nested babies (P<0.0001).
                Diaper change is a distressing procedure for preterm infants. Providing postural support during diaper changes reduces the signs of distress and pain. The purpose of this study was to compare the effectiveness of "facilitated tucking by parents" (FTP) in which a parent holds by her hands the infant in a side-lying flexed position offering support and skin contact, oral glucose, opioid (oxycodone), and placebo (oral water) in the context of heel stick and pharyngeal suctioning in very preterm infants. We hypothesized that nonpharmacologic methods equal the pharmacologic method and are superior to placebo in pain management.
                A prospective randomized placebo-controlled crossover trial. The study patients (n=20) were born at a mean gestational age of 28(+1) weeks and were studied at postconceptional age of 28 to 32 weeks. Pain measurements with Premature Infant Pain Profile and Neonatal Infant Pain Scale covered the first 30 seconds after the beginning of the painful stimulus.
                Premature Infant Pain Profile scores were significantly lower with oral glucose (mean: 4.85+/-1.73, P<or=0.001) and FTP (mean: 5.20+/-1.70, P=0.004) when compared with placebo (mean: 7.05+/-2.16) after heel stick. During pharyngeal suctioning, the scores were lowest with oral glucose (mean: 11.05+/-2.31, P=0.014) and FTP (mean: 11.25+/-2.47, P=0.034) compared with placebo (mean: 12.40+/-2.06). Opioid equaled placebo in both procedures. Neonatal Infant Pain Scale scores were significantly lower with FTP (P<or=0.001) and opioid (P=0.018) after heel stick, and during pharyngeal suctioning with FTP (P=0.001) compared with placebo. We found significantly more short-term adverse effects per administration with oral glucose (21.25%) and oral water (12.5%) compared with opioid (5%) or FTP (5%).
                Our study demonstrated that FTP is not just equal, but preferable to other pain management methods when both efficacy and safety are considered. The effects of behavioral interventions in reducing the stress of infant pain are not well documented. Two comfort interventions, rocking and pacifiers, were compared with routine care administered to 60 newborn infants randomly assigned to the three conditions following a neonatal screening heelstick. Heart rate, state of arousal, and crying were recorded continuously. Both pacifiers and rocking reduced crying, but pacifiers predominantly produced sleep states and rocking predominantly produced alert states. Pacifiers reduced heart rate levels significantly more than did rocking. Thus, newborns clearly benefit from both comforting methods. Several mechanisms are proposed to account for these findings. To test the efficacy of maternal skin-to-skin contact, or kangaroo care (KC), on diminishing the pain response of preterm neonates to heel lancing.
                A crossover design was used, in which the neonates served as their own controls. Subjects Preterm neonates (n = 74), between 32 and 36 weeks' postmenstrual age and within 10 days of birth, who were breathing without assistance and who were not receiving sedatives or analgesics in 3 level II to III neonatal intensive care units in Canada.
                In the experimental condition, the neonate was held in KC for 30 minutes before the heel-lancing procedure and remained in KC for the duration of the procedure. In the control condition, the neonate was in the prone position in the isolette. The ordering of conditions was random.
                The primary outcome was the Premature Infant Pain Profile, which is composed of 3 facial actions, maximum heart rate, and minimum oxygen saturation changes from baseline in 30-second blocks. Videotapes, taken with the camera positioned on the neonate's face so that an observer could not tell whether the neonate was being held or was in the isolette, were coded by research assistants who were naïve to the purpose of the study. Heart rate and oxygen levels were continuously monitored into a computer for later analysis. A repeated-measures analysis of covariance was used, with order of condition and site as factors and severity of illness as a covariate.
                Premature Infant Pain Profile scores across the first 90 seconds from the heel-lancing procedure were significantly (.002<P<.04) lower by 2 points in the KC condition.
                For preterm neonates who are 32 weeks' postmenstrual age or older, KC seems to effectively decrease pain from heel lancing. Further study is needed to determine if younger neonates or those requiring assistance in breathing, or older infants or toddlers, would benefit from KC, or if it would remain effective over several procedures. Given its effectiveness, and that parents of neonates in critical care units want to participate more in comforting their children, KC is a potentially beneficial strategy for promoting family health. The purpose of this study was to compare stress responses of infants born preterm during routine nursing assessments performed under two conditions. One condition incorporated a second caregiver supporting the infant in a facilitated tucked position, whereas the second condition did not.
                A convenience sample of 12 infants born preterm, ages 25 to 34 weeks postconceptual age on the day of testing (mean = 30.9 weeks), were evaluated using the Premature Infant Pain Profile (PIPP), during the two caregiving conditions. For each trial, the infant received a PIPP score. The level of significance was set at p = 0.05.
                A significant difference (p = 0.013) existed between the two testing positions as measured by the PIPP. Nine of the 12 infants received a lower PIPP score with facilitated tucking during routine care assessments.
                By incorporating facilitated tucking during routine care events, the stress level of the infants born preterm may be reduced. When the infants' stress levels are reduced, they may be better able to maintain stability in their autonomic, motor, and state systems. Procedural pain management for very low birth weight (VLBW) neonates has been minimal or nonexistent in most neonatal intensive care units (NICUs).
                To compare the efficacy of developmentally sensitive behavioral interventions (nonnutritive sucking via a pacifier, positioning) and sucrose for relieving procedural pain in VLBW infants and to determine the influence of contextual factors (gestational age, postnatal age, birth weight, severity of illness, frequency of painful procedures) on pain response.
                In a prospective randomized crossover trial, pain was assessed in 122 VLBW neonates using the Premature Infant Pain Profile following four randomly ordered interventions during consecutive routine heel lance procedures.
                Significant differences in pain existed among treatment interventions (F = 16.20, p < .0001). The pacifier with sucrose (F = 24.09, p < .0001) and pacifier with sterile water (F = 9.00, p = .003) significantly reduced pain. Prone positioning did not decrease pain (F = 2.24, p = .137). Frequency of painful procedures approached significance in influencing pain response (F = 3.59, p = .01).
                The most efficacious interventions for reducing pain from single painful events were the pacifier with sucrose and the pacifier with sterile water. Research on the efficacy and safety of implementing these interventions, alone and in combination, for repeated painful procedures is needed. In addition, research is needed on the influence of implementing these interventions on pain response and clinical outcomes (e.g., health status and neurodevelopmental status) in VLBW neonates in the NICU. Distraction has been shown to be an effective technique for managing pain in children; however, few investigations have examined the utility of this technique with infants. The goal of the current study was to investigate the effectiveness of movie distraction in reducing infants' immunization distress. Participants were 136 infants (range=1-21 months; M=7.6 months, SD=5.0 months) and their parents, all of whom were recruited when presenting for routine vaccinations. The parent-child dyads were randomly assigned to either a Distraction or Typical Care control condition. Infant and adult behaviors were assessed using a visual analog scale and a behavioral observation rating scale. Results indicated parents in the Distraction group engaged in higher rates of distraction than those in the Typical Care group, whereas there was no difference in the behavior of nurses in the Distraction and Typical Care groups. In addition, infants in the Distraction group displayed fewer distress behaviors than infants in the Typical Care group both prior to and during recovery from the injection. Findings suggest that a simple and practical distraction intervention can provide some distress relief to infants during routine injections. Infant procedural distress is largely understudied, and there is a dearth of empirically supported interventions in the child health psychology literature. This study examined nurse-directed distraction for reducing infant immunization distress. Ninety infants and their parents were randomly assigned to a distraction condition (i.e., nurses used stimuli to divert infants' attention) or a typical care condition. Outcome measures were an observational scale, parent and nurse ratings, and infant heart rate. Results indicated that infants engaged in distraction and that distraction reduced their behavioral distress; however, ratings and heart rate were inconclusive. Analyses of procedural phases indicated that infants exhibited elevated distress immediately prior to and during an injection, but this distress was fleeting. To measure the difference in pain scores for newborns who were held and swaddled while undergoing routine heel lance procedures compared to newborns who were lying on their backs and not swaddled during heel lance. Additionally, we sought to compare the total amount of time it took to collect the specimens in each group.
                A total of 42 neonates recruited from a large tertiary hospital were enrolled in a randomized controlled trial. Infants in the experimental group (n = 22) were swaddled and held in an upright position during routine heel lance procedures while neonates in the control group (n = 20) remained in a standard care position. Pain was measured with the Neonatal Inventory Pain Scale (NIPS) at two points in time for each group (just before the heel lance procedure and at the completion of the heel lance). Total collection time was measured using a stopwatch accurate to 1/100th of a second. Specimen quality was measured based on the number of rejected specimens for each group. Descriptive statistics and t tests were used to analyze the data.
                The mean NIPS score for neonates who were swaddled and held during the procedure (experimental group) was significantly lower (M = 1.3, SD = .9) than the score for infants in the standard position (control group) (M = 2.7, SD = 1.3), t (40) = -4.48, p < .001. Although the total collection time was lower for infants who were swaddled (2 minutes and 17 seconds, SD = 59) versus (2 minutes and 47 seconds, SD = 85) for controls, this was not a statistically significant difference (p = .45).
                Swaddling combined with positioning neonates upright during routine heel lance procedures offers nurses a nonpharmacologic method of neonatal pain reduction for heel sticks. This technique can be easily implemented on any unit independent of facility protocols. Furthermore, the technique is not associated with any cost or policy development, making it more likely that nurses can use it in practice. This study was designed to investigate whether a brief intervention encouraging parental coping-promoting talk within the treatment room would have beneficial effects on infant pain responses to an immunization injection. Infant-parent dyads were recruited from a 6-month immunization clinic and randomized to an intervention group (n = 25) or standard care control group (n = 25). Parents in the intervention group received an information sheet describing adult verbalizations associated with better pain outcomes for infants. The immunization procedure was videotaped. Parents in the intervention condition made significantly more coping-promoting statements than parents in the control condition. Infants in the control condition cried significantly longer than infants in the intervention condition. Coping-promoting and distress-promoting statements did not differ in terms of affective quality. Infants whose parents had rated them as more difficult in temperament cried longer following the injection. Teaching parents to engage in coping-promoting behaviors within the infant treatment room is an effective, low-cost intervention. Previous randomized trials of the analgesic effects of sucrose, glucose, and a pacifier in term neonates have shown that the pacifier resulted in lower pain scores than glucose or sucrose, but the pacifier with and without sucrose did not differ. The current study was designed to assess the analgesic effect of pharmacologic (sucrose, water) and a non-pharmacologic measures (pacifier) in preterm infants and to find whether there is any synergism between these intervention in relieving pain during painful procedures.
                In this double-blind, randomized, controlled study, 36 preterm infants (mean 31 weeks gestational age, range 27 to 36 weeks) were randomly allocated to six different regimens (0.5 mL sterile water with pacifier, 0.5 mL sterile water without pacifier, 0.5 mL sucrose 24% with pacifier, 0.5 mL sucrose 24% without pacifier, pacifier alone and control group) during a stay in intensive care of up to 15 days. Pain scores were measured with the Premature Infant Pain Profile (PIPP), a validated behavioral acute pain scale.
                Of all the regimens, the lowest pain scores occurred with the use of 24% sucrose solution combined with pacifier. The mean pain score for the combination of sucrose with pacifier was 0.7 as compared to 1.4 for the sterile water with pacifier group (P<.05).
                The synergistic effect of the combination of sucrose and non-nutritive sucking was clinically effective and safe in relieving the pain of simple procedures such as venipuncture or heel stick in preterm and term infants, but further research is needed on these interventions alone and in combination with other behavioral interventions in neonates. To test the effect of nonnutritive sucking (NNS), music therapy (MT), and combined NNS and MT (NNS + MT), versus no intervention, on heart rate, transcutaneous oxygen (TcPaO(2)) levels, and pain behavior of neonates in intensive care units having blood taken by a heel-stick procedure.
                A within-subjects, counter-balancing, repeated-measures design conducted in a government-funded hospital in Hong Kong, comparing TcPaO(2) levels, heart rate, and pain behavior outcomes in 27 neonates.
                Repeated-measures multivariate analysis of variance revealed statistically significant differences in outcomes across all interventions (Wilk's lambda =.142; F [3,27] = 31.82; eta2 =.47). One-way analysis of variance revealed that the 3 comfort interventions significantly reduced neonates' heart rate (Wilk's lambda =.647; F [2,27] = 18.93; eta2 =.35), improved their TcPaO(2) levels (Wilk's lambda =.481; F [2,27] = 37.42; eta2 =.51), and reduced their pain behavior (Wilk's lambda =.312; F [2,27] = 76.42; eta2 =.68). Posthoc scheffe tests revealed that NNS + MT had the strongest effect on neonates' TcPaO(2) levels and pain behavior; MT alone had the strongest effect on neonates' heart rate.
                Health professionals using NNS + MT when doing heel-sticks can improve the TcPaO(2) levels of neonates and reduce their pain. Using MT alone can improve the heart rate of neonates. To determine whether skin-to-skin contact between mothers and their newborns will reduce the pain experienced by the infant during heel lance.
                A prospective, randomized, controlled trial.
                Boston Medical Center, Boston, Massachusetts.
                A total of 30 newborn infants were studied.
                Infants were assigned randomly to either being held by their mothers in whole body, skin-to-skin contact or to no intervention (swaddled in crib) during a standard heel lance procedure.
                The effectiveness of the intervention was determined by comparing crying, grimacing, and heart rate differences between contact and control infants during and after blood collection.
                Crying and grimacing were reduced by 82% and 65%, respectively, from control infant levels during the heel lance procedure. Heart rate also was reduced substantially by contact.
                Skin-to-skin contact is a remarkably potent intervention against the pain experienced during heel stick in newborns. To understand how the 'caregiving context' could affect responses to procedural pain, the authors sought to determine whether (1) the combined effects of sweet taste and holding (caregiving contact) were greater than the effects of either alone, (2) any combined effects were additive or interactive, and (3) the interventions had similar effects on behavioral (crying and facial activity) and physiological (heart rate, vagal tone) responses to the heel-stick procedure in newborn infants in a randomized two-factorial intervention trial. Eighty-five normally developing newborn infants were studied with a mean gestational age of 39.4 weeks on the 2nd or 3rd day of life. Infants were randomized in blocks of eight to receive (1) no holding and water taste (control participants), (2) no holding and sucrose taste (sucrose group), (3) holding and water taste (holding group), or (4) holding and sucrose taste (holding and sucrose group). Crying was reduced significantly by taste and holding, and the interventions combined additively. Facial activity was only significantly reduced by holding. For physiological measures, the interventions interacted with each other and preintervention levels to reduce heart rate and lower vagal tone more during the procedure in infants in whom heart rate and vagal tone were higher before intervention. Consequently, sweet taste and holding interventions combined in complex ways when acting on different behavioral and physiological response systems to modify stressful pain experiences. The results suggest that providing a caregiving context when painful procedures are performed may be a simple and practical method of reducing pain experience in infants, and that no one measure captures these effects. Nonpharmacological interventions are important alternatives for pain relief during minor procedures in preterm neonates. Skin-to-skin contact or kangaroo mother care is a human and efficient way of caring for low-weight preterm neonates. The aim of the present study was to assess the analgesic effect of kangaroo care compared to oral glucose on the response of healthy preterm neonates to a low-intensity acute painful stimulus. Ninety-five preterm neonates with a postmenstrual age of 28-36 weeks were randomly assigned to three groups in a single-blind manner. In group 1 (isolette, n=33), the neonate was in the prone position in the isolette during heel lancing and did not receive analgesia. In group 2 (kangaroo method, n=31), the neonate was held in skin-to-skin contact for 10 min before and during the heel-lancing procedure. In group 3 (glucose, n=31), the neonate was in the prone position in the isolette and received oral glucose (1 ml, 25%) 2 min before heel lancing. A smaller variation in heart rate (p=0.0001) and oxygen saturation (p=0.0012), a shorter duration of facial activity (brow bulge, eye squeeze and nasolabial furrowing) (p=0.0001), and a lower PIPP (Premature Infant Pain Profile) score (p=0.0001) were observed in group 2. In conclusion, skin-to-skin contact produced an analgesic effect in preterm newborns during heel lancing. We examined responses of preterm infants to swaddling after a heel lance. Fifteen preterm infants from two postconceptional age (PCA) groups (Group 1: n = 7, PCA < 31 wk; Group 2: n = 8, PCA > or = 31 wk) were observed for 30 minutes during blood sampling followed by routine care; blood sampling followed by swaddling; and no blood sampling and routine care. In both groups, blood sampling resulted in concurrent increases in heart rate and state of arousal, in negative facial displays, and in reductions in blood oxygensaturation. After the blood was drawn, infants less than 31 weeks PCA exhibited an immediate and spontaneous return to behavioral patterns similar to those observed during the no-blood-sample condition, regardless of treatment condition. Infants 31 weeks PCA or older exhibited protracted behavioral disturbance that was significantly reduced by the use of swaddling. We discuss the significance of these findings. To determine if a recording of a mother's voice talking soothingly to her baby is useful in diminishing pain in newborns born between 32 and 36 weeks' gestational age (GA) during routine painful procedures.
                While maternal skin-to-skin contact has been proven efficacious for diminishing procedural pain in both full-term and preterm neonates, it is often not possible for mothers to be present during a painful procedure. Because auditory development occurs before the third trimester of gestation, it was hypothesized that maternal voice could substitute for maternal presence and be effective in diminishing pain response.
                Preterm infants between 32 and 36 weeks' GA (n = 20) in the first 10 days of life admitted to 2 urban university-affiliated neonatal intensive care units.
                Crossover design with random ordering of condition. Following informed consent, an audio recording of the mother talking soothingly to her baby was filtered to simulate the mother's voice traveling through amniotic fluid. A final 10-minute recording of repetition of mothers' talking was recorded with maximum peaks of 70 decibels (dB) and played at levels ranging between 60 and 70 ambient decibels (dbA), selected above recommendations of the American Academy of Pediatrics in order to be heard over high ambient noise in the settings. This was played to her infant by a portable cassette tape player 3 times daily during a 48-hour period after feedings (gavage, bottle, or breast). At the end of 48 hours when blood work was required for clinical purposes, using a crossover design, the infant underwent the heel lancing with or without the recording being played. The order of condition was randomized, and the second condition was within 10 days. The Premature Infant Pain Profile (PIPP) was used as primary outcome. This is a composite measure using heart rate, oxygen saturation, 3 facial actions, behavioral state, and gestational age. This measure has demonstrated reliability and validity indexes.
                There were no significant differences between groups on the PIPP or any of the individual components of the PIPP except a lower oxygen saturation level in the voice condition following the procedure. The second condition, regardless of whether it was voice or control, had higher heart rate scores and lower oxygen saturation scores even in the prelance baseline and warming phases. Order did not affect PIPP scores or facial actions.
                Different modalities of maternal presence would appear to be necessary to blunt pain response in infants, and recorded maternal voice alone is not sufficient. The loudness of the recording may have obliterated the infant's ability to discern the mother's voice and may even have been aversive, reflected in decreased oxygen saturation levels in the voice condition. Preterm neonates of 32 to 36 weeks' gestation may become sensitized to painful experiences and show anticipatory physiological response. To compare the efficacies of non-nutritive sucking and glucose solution as pain-relief interventions for neonates undergoing a venipuncture procedure.
                Neonates may be subjected to painful procedures. The individual efficacies of non-nutritive sucking or oral glucose solution used alone on pain-relief for neonates still remain controversial.
                A randomised, parallel-group controlled trial was designed.
                A total of 105 neonates were randomly assigned to one of the three groups: non-nutritive sucking, glucose solution, or control group. When a neonate underwent a venipuncture during a newborn screening test, his/her pain manifestations were videotaped and subsequently measured using the Neonatal Infant Pain Scale. Both the stability analysis and the analysis of repeated relationships were performed by generalised estimating equations.
                The level of pain was regressed over the study variables (time and group) and covariate (gestational age). Both the non-nutritive sucking and glucose solution groups had significantly lower pain scores than the control group during the venipuncture and recovery phases. Furthermore, non-nutritive sucking seemed to be more effective than glucose solution.
                Nurses can use a pain assessment tool and the pain-relief intervention to improve the quality of neonatal care in clinical practice. This study indicates that either non-nutritive sucking or glucose solution can effectively decrease the level of pain.
                If a painful procedure on neonates is inevitable, simple, convenient and effective pain-relief methods such as non-nutritive sucking or glucose solution can be provided alone. Based on a neonate's condition, nurses can provide 2 ml of 25% glucose solution through a syringe for a breastfeeding infant before an invasive procedure if nipple confusion is the concern. Leg massage could inhibit the transmission of pain by 'closing the gate' or by activating the endogenous opioid pathway to decrease nociceptive transmission of pain associated with heel stick. The aim of this study is to determine the effects of massage therapy prior to heel stick on responses assessed by the Neonatal Infant Pain Scale (NIPS) (primary outcome), heart rate, respiratory rate and oxygen saturation (secondary outcomes) in infants who required a heel stick for blood sampling.
                This randomised, double-blind, crossover trial with infants from 1 to 7 days post birth excluded those with prior surgery, septicaemia, current assisted ventilation or an analgesic within 48 h. After informed consent, 13 infants received a 2-min massage of the ipsilateral leg prior to heel stick on the first study sampling and no massage on the next sampling 2-7 days later and 10 infants had the reverse order. The bedside nurse, blinded to the intervention, measured NIPS, heart rate, respiratory rate, and oxygen saturation prior to massage, after massage, and 5 min after heel stick. Serum cortisol was measured with the blood sampling.
                In 23 infants (birthweight 795-2507 g), there were no adverse physiologic effects of massage. After heel stick, NIPS (P < 0.001) and heart rate (P = 0.03) were increased in the no-massage group compared with the massage group. Respiratory rate, oxygen saturation and serum cortisol were not significantly different.
                Gentle massage of the leg prior to heel stick is safe and decreases pain responses in preterm infants. We investigated if nonnutritive sucking (NNS) during heelstick procedures alleviates behavioral distress in neonates. In our NICU, 26 neonates without severe complications (mean Minde score 0.8, range 0-3), undergoing heelstick procedures at least twice a day, in the first 2 weeks of life, were enrolled in the trial (mean gestational age 33.9 weeks, range 26-39 weeks, mean birth weight 1, 988.5 g, range 1,200-4,010 g, mean Apgar score at the first minute 6. 7, range 4-10, at the fifth minute 8.5, range 6-10). Two heelpricks were performed in each neonate with NNS randomly assigned. Behavioral states, transcutaneous oxygen tension (TcPO(2)), heart rate, and respiratory rate were monitored before, during and after the heelstick procedures. Heelstick procedures lasted for a mean of 109 s (range 50-230 s) with NNS, and a mean of 128.8 s (range 20-420 s) without NNS. Compared with baseline, heart rate and behavioral distress increased and respiratory rate decreased during heelstick and after heelstick. Oxygen tension did not change. Nonnutritive sucking had no effect on respiratory rate or transcutaneous oxygen tension, but reduced the time of crying and the heart rate increase during the procedure. In conclusion, NNS can be recommended to reduce distress in newborns undergoing invasive routine procedures. Further studies are needed to evaluate the effects of NNS on respiratory rate and blood gas levels.
                Copyright 2000 S. Karger AG, Basel To examine the efficacy of pacifiers and sugar, alone and in combination, for pain management in neonates.
                An experimental design examined pain responses of 84 newborns undergoing heelstick. They were randomly assigned to one of four groups: (a) water-moistened pacifier, (b) sugar-coated pacifier, (c) 2 cc of a 12% oral sucrose solution, or (d) control. Pain measures were duration of cry, vagal tone, and salivary cortisol.
                Multivariate analysis of variance (MANOVA) revealed that the sugar-coated pacifier group cried significantly less than the water-moistened pacifier and control groups. Repeated measures analysis of variance (ANOVA) revealed that the sugar-coated pacifier group demonstrated significantly lower vagal tone during heelstick than the oral sucrose solution and control groups. This difference between the sugar-coated pacifier and control groups persevered for 15 minutes after heelstick.
                Offering a sugar coated pacifier during heelstick in healthy neonates reduces pain behaviors more effectively than a water-moistened pacifier, 2 cc of a 12% sucrose solution, or no intervention. Pain expression in the neonate (NN) is affected by intrinsic and extrinsic factors (gestational and postconceptional age, states, and painful experiences). The impact of developmental care is discussed in relation to defined pain expression. The aim of this randomized crossover study was to determine the impact of developmental care on pain expression during a nursing intervention in preterm NNs. Nineteen preterm NNs (gestational age, 29 +/- 1.8 weeks body weight, 1212 +/- 255 g) were included. Each NN experienced 2 randomly ordered diaper changes (with and without developmental support). Physiologic responses (heart rate, oxygen saturation, hypoxic events with SaO(2) less than 80%, bradycardia less than 80 beats/min) were studied during 3 periods: baseline, diaper change (time 0), and recovery period. Pain expression was evaluated with 2 pain scales: chronic pain with Echelle Douleur et Inconfort ([EDIN] or Pain and discomfort scale for newborns) at time B60 minutes, 0, +30 minutes, and +60 minutes and procedural pain with the Preterm Infant Pain Profile (PIPP) at time 0. Statistical analysis was conducted with a Wilcoxon nonparametric test. PIPP, EDIN 0, EDIN + 30 minutes, and EDIN + 60 minutes scores were significantly decreased with developmental care versus without developmental care: 8.7 +/- 1.9 v 11.1 +/- 2.36 (P < .01) 0.6 +/- 0.5 v 3.2 +/- 2.9 (P < .01);0.33 +/- 0.5 v 3.9 +/- 2.5 (P < .001);0.3 +/- 3.4 v 3.4 +/- 3 (P < .001), respectively. Hypoxic events rate was decreased with developmental care during the baseline and diaper change periods. The lowest oxygen saturation observed during the PIPP measure was significantly higher with developmental care (88.8% +/- 3% v 81.8% +/- 4% P < .01). Developmental care significantly decreased the PIPP and EDIN pain scores and hypoxic events during a routine nursing intervention.
There is evidence that different non-pharmacological interventions can be used with preterms, neonates, and older infants to significantly manage pain behaviors associated with acutely painful procedures.
