Pre-anesthetic anxiety and emergence agitation are major challenges for anesthesiologists in pediatric anesthesia. Thus, sedative premedication and parental presence during induction of anesthesia (PPIA) are used to treat pre-anesthetic anxiety in children. The aim of the present study was to test if a combination of mother presence and midazolam premedication is effective for improving emergence condition in children undergoing general anesthesia.
                Sixty children were allocated to one of three groups: a sedative group (0.5 mg/kg oral midazolam), a PPIA group or a sedative and PPIA group. When anesthesia was induced with 7% sevoflurane in 100% oxygen, qualities of mask induction were rated. Anesthesia was maintained with sevoflurane (1.5-2.5%) in 60% oxygen and intravenous fentanyl 4 microg/kg. During emergence from anesthesia, the score of the child's emergence behavior was rated.
                The children in the midazolam group showed a better quality of mask induction compared with those in the PPIA group, the addition of parental presence to oral midazolam did not provide additional improvement of mask induction. In contrast, the children in the midazolam + PPIA group were less agitated than those in the other groups at emergence from anesthesia.
                Parental presence during induction of anesthesia enhanced the effect of oral midazolam on emergence behavior of children undergoing general anesthesia. In this study, we examined whether interactive music therapy is an effective treatment for preinduction anxiety. Children undergoing outpatient surgery were randomized to 3 groups: interactive music therapy (n = 51), oral midazolam (n = 34), or control (n = 38). The primary outcome of the study was children's perioperative anxiety. We found that children who received midazolam were significantly less anxious during the induction of anesthesia than children in the music therapy and control groups (P = 0.015 and P = 0.005, respectively). We found no difference in anxiety during the induction of anesthesia between children in the music therapy group and children in the control group. An analysis controlling for therapist revealed a significant therapist effect; i.e., children treated by one of the therapists were significantly less anxious than children in the other therapist group and the control group on separation to the operating room (OR) (P < 0.05) and on entrance to the OR (P < 0.05), but not on the introduction of the anesthesia mask (P = not significant). Children in the midazolam group were the least anxious even after controlling for therapist effect (P < 0.05). We conclude that music therapy may be helpful on separation and entrance to the OR, depending on the therapist. However, music therapy does not appear to relieve anxiety during the induction of anesthesia.
                Depending on the music therapist, interactive music therapy may relieve anxiety on separation and entrance to the operating room but appears less effective during the induction of anesthesia. Children and parents experience significant anxiety and distress during the preoperative period. Currently available interventions are having limited efficacy. Based on an integration of the literature in both the anesthesia and psychological milieus, the authors developed a behaviorally oriented perioperative preparation program for children undergoing surgery that targets the family as a whole.
                Children and their parents (n = 408) were randomly assigned to one of four groups: (1) control: received standard of care; (2) parental presence: received standard parental presence during induction of anesthesia; (3) ADVANCE: received family-centered behavioral preparation; and (4) oral midazolam. The authors assessed the effect of group assignment on preoperative anxiety levels and postoperative outcomes such as analgesic consumption and emergence delirium.
                Parents and children in the ADVANCE group exhibited significantly lower anxiety in the holding area as compared with all three other groups (34.4+/-16 vs. 39.7+/-15; P=0.007) and were less anxious during induction of anesthesia as compared with the control and parental presence groups (44.9+/-22 vs. 51.6+/-25 and 53.6+/-25, respectively; P=0.006). Anxiety and compliance during induction of anesthesia was similar for children in both the ADVANCE and midazolam groups (44.9+/-22 vs. 42.9+/-24; P=0.904). Children in the ADVANCE group exhibited a lower incidence of emergence delirium after surgery (P=0.038), required significantly less analgesia in the recovery room (P=0.016), and were discharged from the recovery room earlier (P=0.04) as compared with children in the three other groups.
                The family-centered preoperative ADVANCE preparation program is effective in the reduction of preoperative anxiety and improvement in postoperative outcomes. We assessed the effectiveness of a behavioral intervention aimed at reducing the anxiety of children undergoing anesthesia and surgery. The intervention consisted of dimmed operating room (OR) lights (200 Lx) and soft background music (Bach's "Air on a G String," 50-60 dB). Only one person, the attending anesthesiologist, interacted with the child during the induction of anesthesia. Children undergoing anesthesia and surgery were randomly assigned either to a low sensory stimulation group (LSSG, n = 33) or to control group (n = 37). By using validated behavioral measures of anxiety (mYPAS) and compliance (ICC), children were evaluated at the preoperative holding area and during the induction of anesthesia. On postoperative Days 1, 2, 3, 7, and 14, the behavioral recovery of the children was assessed by using the Post Hospitalization Behavior Questionnaire. We found that the LSSG was significantly less anxious compared with the control group on entrance to the OR (P = 0.03) and on the introduction of the anesthesia mask (P = 0.003). Also, the compliance during the induction of anesthesia was significantly better in children assigned to the LSSG (P = 0.02). The incidence of postoperative behavioral changes, however, did not differ significantly between the two groups (P = ns). We conclude that children who are exposed to low-level sensory stimuli during the induction of anesthesia and who are exposed to background music exhibit lower levels of anxiety and increased compliance.
                Children are less anxious and show increased compliance during induction when exposed to a single care-provider in a dimmed, quiet operating room with background music. Although some anesthesiologists use oral sedatives or parental presence during induction of anesthesia (PPIA) to treat preoperative anxiety in children, others may use these interventions simultaneously (e.g., sedatives and PPIA). The purpose of this investigation was to determine whether this approach has advantages over treating children with sedatives alone.
                The child's and the parental anxiety throughout the perioperative period was the primary endpoint of the study. Parental satisfaction was the secondary endpoint. Subjects (n = 103) were assigned randomly to one of two groups: a sedative group (0.5 mg/kg oral midazolam) or a sedative and PPIA group. Using standardized measures of anxiety and satisfaction, the effects of the interventions on the children and parents were assessed. Statistical analysis (varimax rotation) of the satisfaction questionnaire items resulted in two factors that described satisfaction of the separation process and satisfaction of the overall care provided.
                Anxiety in the holding area, at entrance to the operating room, and at introduction of the anesthesia mask did not differ significantly between the two groups (F[2,192] = 1.26, P = 0.28). Parental anxiety after separation, however, was significantly lower in the sedative and PPIA group (F[2,93] = 4.46, P = 0.037). Parental satisfaction with the overall care provided (-0.28 +/- 1.2 vs. 0.43 +/- 0.26, P = 0.046) and with the separation process (-0.30 +/- 1.2 vs. 0.47 +/- 0.20, P = 0.03) was significantly higher among the sedative and PPIA group compared with the sedative group.
                PPIA in addition to 0.5 mg/kg oral midazolam has no additive effects in terms of reducing a child's anxiety. Parents who accompanied their children to the operating room, however, were less anxious and more satisfied. Both midazolam and parental presence during induction of anesthesia are routinely used to treat preoperative anxiety in children. The purpose of this investigation was to determine which of these two interventions is more effective.
                Anxiety of the child during the perioperative period was the primary end point. Secondary end points included anxiety of the parent and compliance of the child during induction. Children (n = 88) were randomly assigned to one of three groups: (1) 0.5 mg/kg oral midazolam; (2) parental presence during induction of anesthesia; or (3) control (no parental presence or premedication). Using multiple behavioral measures of anxiety, the effect of the intervention on the children and their parents was assessed.
                Observed anxiety in the holding area (T1), entrance to the operating room (T2), and introduction of the anesthesia mask (T3) differed significantly among the three groups (P = 0.032). Post hoc analysis indicated that children in the midazolam group exhibited significantly less anxiety compared with the children in the parental-presence group or control group (P = 0.0171). Similarly, parental anxiety scores after separation were significantly less in the midazolam group compared with the parental-presence or control groups (P = 0.048). The percentage of inductions in which compliance of the child was poor was significantly greater in the control group compared with the parental-presence and midazolam groups (25% vs. 17% vs. 0%, P = 0.013).
                Under the conditions of this study, oral midazolam is more effective than either parental presence or no intervention for managing a child's and parent's anxiety during the preoperative period. Fear and anxiety in a child undergoing surgery are correlated positively with the parent's level of anxiety, and interventions to decrease the parent's anxiety are appropriate. The purpose of this study was to determine whether viewing a video of an actual pediatric inhalation induction would reduce the level of parental anxiety. Eighty patients requiring an inhalation anesthetic induction were selected and randomized to 2 groups. Parents in the experimental group (group 1; n = 40) viewed a video demonstrating pediatric mask induction. Parents in the control group (group 2; n = 40) received an information pamphlet only. Anxiety was measured perioperatively in the parents and their children. Mean arterial pressure for children in group 1 was significantly lower during preoperative holding and following induction (P < .05). The level of anxiety postoperatively of children and parents in group 1 was significantly lower than that of children and parents in group 2 (P < .05). Viewing a preoperative video seems to be beneficial. Decreasing the parent's level of anxiety preoperatively may have a positive effect on the child's level of anxiety expressed postoperatively. To determine whether parental presence during induction of anesthesia is an effective preoperative behavioral intervention, a randomized controlled trial with children undergoing outpatient surgery was conducted.
                Eighty-four children were randomly assigned to a parent-present or parent-absent group. Using multiple behavioral and physiologic measures of anxiety, the effect of the intervention on the children and their parents was assessed. Predictors for the response to the intervention were examined using multivariate linear regression analysis.
                When the intervention group (parent-present) was compared to the control group (parent-absent), overall there were no significant differences in any of the behavioral or physiologic measures of anxiety tested during induction of anesthesia. Using the child's serum cortisol concentration as the outcome, parental presence, the child's age and baseline temperament, and trait anxiety of the parent, were identified as predictors of the child's anxiety during induction. Analysis of variance demonstrated that three groups showed diminished cortisol concentrations with parental presence: children older than 4 yr (P = 0.001), children whose parent had a low trait anxiety (P = 0.02), and children who had a low baseline level of activity as assessed by temperament (P = 0.05).
                Children who were older than 4 yr or those with a parent with a low trait anxiety or who had a low baseline level of activity/temperament benefited from parental presence during induction. Parental presence at induction of anaesthesia is desirable if it makes the child happier and more cooperative. This study evaluated the emotional and behavioural responses of children to being accompanied by a parent at induction of anaesthesia in a paediatric day-care surgical centre. One hundred and thirty-four patients (aged 2-10 yr, ASA physical status I or II) were divided into two groups by day of surgery, to have a parent present at induction of anaesthesia (treatment group), or to be unaccompanied (control group). Before, and at one week after surgery, the child's fears and behaviour were scored by the Hospital Fears Inventory (HFI) and Behavioural Questionnaire (BQ), and parental anxiety by the Parents' Questionnaire (PQ) before and at one week after surgery. The Global Mood Scale (GMS) was used to assess the child's behaviour and the Visual Analogue Scale (VAS) to assess the parent's anxiety on arrival for surgery and at induction of anaesthesia. All patients and parents were disturbed by the experience, but to the same degree in the treatment and control groups. Subgroups of "calm" and "anxious" parents were identified by a median split of their preoperative VAS scores. Children in the "calm-treatment," "calm-control" and "anxious-control" subgroups were similarly upset at induction. Children in the "anxious-treatment" subgroup were the most disturbed at induction, and significantly more than those in the "anxious-control" subgroup. Preoperative parental anxiety levels also correlated with the child's fears and behaviour one week after surgery.(ABSTRACT TRUNCATED AT 250 WORDS) The purpose of this study was to determine whether parental auricular acupuncture reduces parental preoperative anxiety and thus allows children to benefit from parental presence during induction of anesthesia.
                Mothers of children who were scheduled to undergo surgery were randomly assigned to an acupuncture intervention group (auricular press needles at relaxation, tranquilizer point, and master cerebral point) or a sham acupuncture control group (auricular press needles at the shoulder, wrist, and extraneous auricular point). The intervention was performed at least 30 min before the child's induction of anesthesia. All mothers were present during induction of anesthesia. The behavioral and physiologic anxiety of mothers and children were rated during the perioperative process.
                : Multivariable analysis examining maternal anxiety as a function of group found a group-by-time interaction (F1,65 = 4.1, P = 0.04). That is, after induction, maternal anxiety in the acupuncture group was significantly lower (42.9 +/- 10 vs. 49.5 +/- 11; P = 0.014). A multivariate model (F1,65 = 4.8, P =0.031) also showed that children whose mothers received the acupuncture intervention were significantly less anxious on entrance to the operating room (34.9 +/- 20 vs. 47.4 +/- 26; P = 0.03) and during introduction of the anesthesia mask (38.6 +/- 25 vs. 55.6 +/- 31; P = 0.016). There were no significant differences in maternal blood pressure and heart rate between the two groups.
                : Auricular acupuncture significantly decreased maternal anxiety during the preoperative period. Children of mothers who underwent acupuncture intervention benefitted from the reduction of maternal anxiety during the induction of anesthesia. Video games have received widespread application in health care for distraction and behavior modification therapy. Studies on the effect of cognitive distraction during the preoperative period are lacking. We evaluated the efficacy of an interactive distraction, a hand-held video game (VG) in reducing preoperative anxiety in children.
                In a randomized, prospective study of 112 children aged 4-12 years undergoing outpatient surgery, anxiety was assessed after admission and again at mask induction of anesthesia, using the modified Yale Preoperative Anxiety Scale (mYPAS). Postoperative behavior changes were assessed with the Posthospital Behavior Questionnaire (PHBQ). Patients were randomly assigned to three groups: parent presence (PP), PP+a hand-held VG, and PP+0.5 mg.kg-1 oral midazolam (M) given>20 min prior to entering the operating room.
                There was a statistically significant increase in anxiety (P<0.01) in groups M and PP at induction of anesthesia compared with baseline, but not in VG group. VG patients demonstrated a decrease in anxiety from baseline (median change in mYPAS -3), the difference compared with PP (+11.8) was significant (P=0.04). The change in anxiety in the M group (+7.3) was not statistically different from other groups. Sixty-three percent of patients in VG group had no change or decrease in anxiety after treatment, compared with 26% in M group and 28% in PP group (P=0.01). There was no difference in anxiety changes between female and male patients.
                A hand-held VG can be offered to most children as a low cost, easy to implement, portable, and effective method to reduce anxiety in the preoperative area and during induction of anesthesia. Distraction in a pleasurable and familiar activity provides anxiety relief, probably through cognitive and motor absorption. We conducted a randomized controlled trial of parental presence during anaesthesia induction for outpatient surgery in 73 infants (aged 1-12 months). Effects of parental presence on infant and parental outcomes, including anxiety, health care attitudes and satisfaction with the anaesthesia and surgery experience were evaluated. Results demonstrated that parental presence had no impact on infant behavioural distress during induction. In addition, parents who were present demonstrated comparable anxiety levels and health care attitudes before and after surgery, as well as comparable levels of satisfaction with the surgical experience compared to parents who were absent during induction. We discuss reasons for the lack of treatment effects from parental presence, and new directions for future research to identify subgroups of children who may most benefit from the opportunity to have parents involved in the perioperative period. The purpose of this study was to determine whether audiovisual information, describing the process of undergoing and recovering from anesthesia, could reduce anxiety levels in parents before their child's induction of anesthesia.
                One hundred and eleven parents were recruited into this study. Of these 56 were randomized to a control group and 55 to an intervention group. All parents completed the Amsterdam Preoperative Anxiety and Information Scale (APAIS) questionnaires on admission to hospital on the day of surgery and then again just before accompanying their child to the anesthetic room. In addition to the normal preoperative preparation, parents randomized into the study group watched a short 8-min information video after completing the first questionnaire. The video illustrated the events and procedures surrounding a child's admission to hospital for day-case surgery, including the induction of anesthesia.
                The results were analyzed using repeated measures of anova. There was a statistically significant reduction in anxiety and desire for information in the intervention group compared with the control group (P < 0.05).
                The reduction in anxiety in the intervention group indicates that preoperative information videos are an effective method of reducing anxiety in parents. Furthermore, the reduction in need for information score in the intervention group indicates that preoperative videos may be a useful tool for providing parents with information. The authors conducted a randomized controlled trial to determine whether parental presence during induction of anesthesia (PPIA) is associated with parental physiologic and behavioral manifestations of stress.
                Children and their parents (N = 80) were randomly assigned to one of three groups: (1) PPIA; (2) PPIA plus 0.5 mg/kg oral midazolam; and (3) control (no PPIA or midazolam). The effect of the group assignment on parental heart rate (HR), parental blood pressure, and parental skin conductance level (SCL) were assessed. Both parental HR and parental SCL were monitored continually. Anxiety of the parent and child was also assessed.
                Parental HR increased from baseline until the induction of anesthesia (P = 0.001). A group-by-time effect ( P= 0.005) was also found. That is, throughout the induction period there were several time points at which parents in the two PPIA groups had a significantly higher HR than did parents in the control group (P < 0.05). Similarly, SCL was found to increase in all parents from baseline until induction of anesthesia (P = 0.001). Significant group differences in SCL changes over time were found as well (P = 0.009). State anxiety and blood pressure following induction of anesthesia did not differ significantly between groups ( P= nonsignificant). Examination of parental Holter data revealed no rhythm abnormalities and no electrocardiogram changes indicating ischemia.
                The authors found that PPIA is associated with increased parental HR and SCL. However, no increased incidence of electrocardiogram abnormalities were found in parents present during induction of anesthesia. The main objectives of premedication in children are to facilitate the separation from the parents, to reduce preoperative anxiety, to smooth the induction of anesthesia and to lower the risk of postoperative behavioral disorders. The most common technique is sedative premedication with midazolam. Hypnosis enables a state of relaxation to be achieved and has never been evaluated as a premedication technique. The aim of the present study was to evaluate the efficacy of hypnosis on anxiety and perioperative behavioral disorders versus midazolam.
                Fifty children from 2 to 11 years of age were randomized into two groups: group H received hypnosis as premedication; group M were given 0.5 mg x kg(-1) midazolam orally, 30 min before surgery. Preoperative anxiety was evaluated using the Modified Yale Preoperative Anxiety Scale (mYPAS) score when arriving in the department (T1), when entering the operating room (T2), and when fitting the facemask (T3). Postoperative behavioral disorders were evaluated using the Posthospitalization Behavioral Questionnaire (PHBQ) at days 1, 7 and 14.
                The two groups showed no significant difference preoperatively with the PHBQ: (M) 21 (17-25) vs (H) 20 (8-25) and mYPAS score: (M) 28 (23-75) vs (H) 23 (23-78). The number of anxious children was less during induction of anesthesia in the hypnosis group (T3: 39% vs 68%) (P < 0.05). Postoperatively, hypnosis reduced the frequency of behavior disorders approximately by half on day 1 (30% vs 62%) and day 7 (26% vs 59%).
                Hypnosis seems effective as premedication in children scheduled for surgery. It alleviates preoperative anxiety, especially during induction of anesthesia and reduces behavioral disorders during the first postoperative week. The induction of anesthesia is one of the most stressful moments for a child who must undergo surgery: it is estimated that 60% of children suffer anxiety in the preoperative period. Preoperative anxiety is characterized by subjective feelings of tension, apprehension, nervousness, and worry. These reactions reflect the child's fear of separation from parents and home environment, as well as of loss of control, unfamiliar routines, surgical instruments, and hospital procedures. High levels of anxiety have been identified as predictors of postoperative troubles that can persist for 6 months after the procedure. Both behavioral and pharmacologic interventions are available to treat preoperative anxiety in children.
                The aim of this study was to investigate the effects of the presence of clowns on a child's preoperative anxiety during the induction of anesthesia and on the parent who accompanies him/her until he/she is asleep.
                The sample was composed of 40 subjects (5-12 years of age) who had to undergo minor day surgery and were assigned randomly to the clown group (N = 20), in which the children were accompanied in the preoperative room by the clowns and a parent, or the control group (N = 20), in which the children were accompanied by only 1 of his/her parents. The anxiety of the children in the preoperative period was measured through the Modified Yale Preoperative Anxiety Scale instrument (observational behavioral checklist to measure the state anxiety of young children), and the anxiety of the parents was measured with the State-Trait Anxiety Inventory (Y-1/Y-2) instrument (self-report anxiety behavioral instrument that measures trait/baseline and state/situational anxiety in adults). In addition, a questionnaire for health professionals was developed to obtain their opinion about the presence of clowns during the induction of anesthesia, and a self-evaluation form was developed to be filled out by the clowns themselves about their interactions with the child.
                The clown group was significantly less anxious during the induction of anesthesia compared with the control group. In the control group there was an increased level of anxiety in the induction room in comparison to in the waiting room; in the clown group anxiety was not significantly different in the 2 locations. The questionnaire for health professionals indicated that the clowns were a benefit to the child, but the majority of the staff was opposed to continuing the program because of perceived interference with the procedures of the operating room. The correlation between the scores of the form to self-evaluate the effectiveness of the clowns and of the Modified Yale Preoperative Anxiety Scale is significant for both the waiting room and induction room.
                This study shows that the presence of clowns during the induction of anesthesia, together with the child's parents, was an effective intervention for managing children's and parents' anxiety during the preoperative period. We would encourage the promotion of this form of distraction therapy in the treatment of children requiring surgery, but the resistance of medical personnel make it very difficult to insert this program in the activity of the operating room. The aim of this study was to establish the efficacy of two different preparation packages, a paper-based cartoon and an interactive computer, at facilitating coping behavior in children undergoing dental general anesthetic (DGA) tooth extraction.
                A total of 198 children were allocated randomly to computer, cartoon or control groups. A Visual Analog Scale (VAS) and Modified Child Dental Anxiety Scale (MCDAS) were used to compare preoperative anxiety levels between the three study groups. Blinded observers then scored behavior at both anesthesia induction and upon recovery using a VAS for each (0 = coped/no distress and 10 = no coping/high distress).
                The children's median age was 5 (range 3-10) years, 57% were boys, a median of seven teeth were extracted (range 1-20). Preoperative anxiety was similar for all preparation groups; with 24% of all children categorized 'phobic' using MCDAS. The median induction (coping) VAS level for both the computer and the cartoon groups was '1' (range 0-10), compared with the control group level of '3' (range 0-10). The median recovery (coping) VAS levels were: computer group: 0 (range 0-10), cartoon group: 4 (range 0-10) and control group: 2.5 (range 0-10). The Mann-Whitney U-test showed that the computer group coped significantly better than the control group at induction (P = 0.014) and significantly better than the cartoon group upon recovery (P = 0.016). The statistical power for detecting differences between groups (computer/cartoon versus control) was calculated to be 90%, based on pilot study data.
                The computer preparation package facilitated coping behavior in children undergoing DGA induction.
