Morphine Versus Methadone Treatment for Neonatal Withdrawal and Impact on Early Infant Development
نویسندگان
چکیده
Objective. Compare developmental outcomes in infants treated with morphine versus methadone. Method. Retrospective chart review of newborns identified through use of ICD-9 code for neonatal abstinence syndrome (NAS). Thirty-six infants were evaluated-17 treated with methadone and 19 treated with morphine. Assessment was completed following treatment using the Bayley Scales of Infant and Toddler Development-Third Edition (Bayley-III). Scores in Cognitive, Language, and Motor domains were compared. Results. Comparison of scores between morphine- and methadone-treated groups revealed differences in mean Cognitive Composite (91.3 vs 83.0; P = .03410) and mean Total Motor Composite Scores (96.3 vs 89.6; P = .0149). Conclusion. Newborns with NAS treated with morphine had significantly higher scores in Cognitive and Gross Motor domains compared to infants treated with methadone. Development screening should be pursued to determine if this difference persists throughout early childhood. Results may influence accepted treatment protocols for NAS.

Pregnancy can motivate opioid-dependent women to seek substance abuse treatment. Research has demonstrated that although prenatal exposure to buprenorphine results in less severe neonatal abstinence syndrome (NAS) relative to prenatal methadone exposure, the maternal and other neonatal outcomes are similar for the two medications. Maternal and neonatal outcomes for opioid-dependent pregnant wom...

Increasing rates of maternal opioid use during pregnancy and neonatal withdrawal, termed neonatal abstinence syndrome (NAS), are public health concerns. Prenatal buprenorphinemaintenance treatment (BMT) versusmethadone maintenance treatment (MMT) may improve neonatal outcomes, but associations vary.

BACKGROUND The prevalence of maternal drug use during pregnancy in North America has been estimated to be as high as 6-10%. The consequences for the newborn include increased risk for perinatal mortality and ongoing physical, neurobehavioral, and psychosocial problems. Methadone is frequently used to wean women off street drugs but is implicated as a cause of adverse fetal/neonatal outcomes its...
