Antenatal methadone vs buprenorphine exposure and length of hospital stay in infants admitted to the intensive care unit with neonatal abstinence syndrome

摘要

OBJECTIVE: Antenatal exposure to methadone or buprenorphine often causes neonatal abstinence syndrome (NAS) in newborns. However, comparative effects on affected infants' hospital courses are inconclusive. We sought to estimate the relationship of antenatal exposure with methadone or buprenorphine and infants' length of stay among hospitalized infants with NAS.
