Observation and treatment of neonatal narcotic withdrawal. Clonidine as an adjunct therapy to opioids for neonatal abstinence syndrome: a randomized, controlled trial.

nan nan A total of 110 infants born to mothers who were either in a methadone maintenance program, using heroin, or recently detoxified, were studied during the neonatal period. Of these infants, 93.6 per cent developed withdrawal symptoms. No significant differences were determined in therapeutic response among those infants treated with methadone, phenobarbital, and diazepam. There was a significant reduction in the frequency of withdrawal symptoms among infants born to mothers whose methadone dose at time of delivery was less than 20 mg (17.9 per cent). It is suggested that reduction of methadone dosage in late pregnancy results in reduced incidence of withdrawal but must be carefully carried out. To determine if oral clonidine would reduce the duration of opioid detoxification for neonatal abstinence syndrome.
                Infants with intrauterine exposure to methadone or heroin and neonatal abstinence syndrome (2 consecutive modified Finnegan scores of > or =9) were enrolled at 2 hospitals during 2002-2005 and followed until final hospital discharge. All enrolled infants (80) received oral diluted tincture of opium according to a standardized algorithm and were randomly assigned to receive oral clonidine (1 microg/kg every 4 hours) (40 infants) or placebo (40 infants). Primary outcome was duration of opioid therapy. Secondary outcomes included the amount of opium required to control symptoms, number of treatment failures, and differences in blood pressure, heart rate, and oxygen saturation.
                The median length of therapy was 27% shorter in the clonidine group (11 [95% confidence interval: 8-15 days]) than in the placebo group (15 days [95% confidence interval: 12-17 days]). In the clonidine group, 7 infants required restarting opium after initial discontinuation versus none in the placebo group, with the total length of treatment/observation remaining significantly less in the clonidine group. Higher dosages of opium were required by 40% of the infants in the placebo group versus 20% in the clonidine group. Treatment failures occurred in 12.5% of the infants in the placebo group versus none in the clonidine group. Hypertension, hypotension, bradycardia, or desaturations did not occur in either group. Three infants in the clonidine group died as a result of myocarditis, sudden infant death syndrome, and homicide, all after hospital discharge and before 6 months of age.
                In this randomized, double-blind trial, adding clonidine to standard opioid therapy for detoxification from in utero exposure to methadone or heroin reduced the duration of pharmacotherapy for neonatal abstinence without causing short-term adverse cardiovascular outcomes. A larger trial is indicated to determine long-term safety. The purpose of this study was to test the hypothesis that treatment of neonatal opiate withdrawal (NOW) in the term infant with diluted tincture of opium (DTO) and phenobarbital was superior to treatment with DTO alone. Study design: This was a partially randomized, controlled trial in which 20 term infants exposed to methadone and/or heroin in utero were studied. The severity of NOW was assessed by using the Finnegan scoring system. Infants were assigned to either DTO and placebo (n = 10) or DTO and phenobarbital (n = 10) when medication was required. The primary outcome variable was the duration of hospitalization. Severity of withdrawal and hospital cost were secondary outcome variables.
                There were no significant differences in the gestational age, growth variables, maternal methadone dose, or age at enrollment between the 2 groups. The duration of hospitalization was reduced by 48% (79-38 days) (P <.001) and hospital cost per patient reduced by $35,856 (P <.001) for the DTO and phenobarbital group. Furthermore, these infants spent less time with severe withdrawal (P <.04), more time with mild withdrawal (P <.03), and required a lower maximum daily DTO dose (P <.009) when compared with the DTO-only group. The average duration of outpatient phenobarbital use was 3.5 months.
                The combined use of DTO and phenobarbital resulted in a shorter duration of hospitalization, less severe withdrawal, and reduced hospital cost. This combination may be a preferred regimen for the treatment of NOW. The majority of infants born to drug-dependent women undergo neonatal abstinence syndrome (NAS) and often require pharmacotherapy for the treatment of withdrawal symptoms. Phenobarbital, paregoric, and diazepam have been recommended for the treatment of the syndrome. While some investigators have examined the efficacy of these agents in treating NAS, there are no data regarding the use of specific pharmacologic agents and developmental outcome. This study evaluated 85 infants born to drug-dependent women who were maintained on methadone during pregnancy. Severity of infant withdrawal was assessed with the neonatal abstinence scoring system. Infants who required pharmacotherapy were randomly assigned to one of four treatment regimens: paragoric, phenobarbital (titration), phenobarbital (loading), and diazepam. When treatment was not successful with the assigned agent, one of the other agent(s) was used. At 6 months of age, the developmental status of infants was assessed with the Bayley Scales of Mental Development. Based on NAS treatment, four groups were defined: paregoric (n = 21); phenobarbital (n = 17); more than one agent (n = 31); and no treatment (n = 16). Data for the phenobarbital loading and titration groups were combined since analysis revealed no differences between groups. All infants who initially received diazepam were included in group III since diazepam as a single agent was not successful. Results of one way analysis of variance revealed no differences in developmental status between groups (p greater than 0.10, F = 0.25). Scores for all groups were well within the normal range of development.(ABSTRACT TRUNCATED AT 250 WORDS)
