Sleep-Related Arousal And Spontaneous Movement Properties In Methadone-Exposed Neonates: A Videographic Assessment On The First Or Second Postnatal Night, Hira Shrestha
Electronic Theses and Dissertations
Prenatal substance exposure such as alcohol, nicotine, and opiates is known to modulate autonomic regulatory function during sleep, and to decrease arousability and spontaneous movements (SM). SM during sleep may reflect a protective mechanism for immature patterns of arousals. Neurodevelopmental compromise in sleep and arousal systems may underlie sudden infant death syndrome (SIDS) risk in which infants expire during sleep. Previous studies from our laboratory found abnormal patterns of neonatal arousal, sleep fragmentation, and deficits in sleep-related SM in infants with prenatal alcohol exposure. In this study, prenatal exposure to methadone was hypothesized to disrupt the development of sleep and …
