ABSTRACT OBJECTIVES To evaluate the use of sedatives and analgesics during therapeutic hypothermia in encephalopathic neonates and assess associations between medication exposure and
hospital outcomes. STUDY DESIGN We identified neonates ≥35 weeks gestational age treated with therapeutic hypothermia at 125 neonatal intensive care units between 2007 and 2015. We compared
characteristics and hospital outcomes between unexposed neonates and neonates exposed to opioids and/or benzodiazepines. RESULTS Opioids were administered to 1 677/2 621 (64%) neonates, and
exposure increased from 38% in 2008 to 68% in 2015. Sedation/analgesia varied widely between centers. Opioid-exposed neonates experienced greater durations of respiratory support and were
more likely to receive inotropes and inhaled nitric oxide. Mortality during postnatal days 0–3 was lower among opioid-exposed neonates (31/625 [5%]) than unexposed neonates (64/714 [9%]).
CONCLUSIONS Sedation/analgesia during therapeutic hypothermia is prevalent but not uniform across centers. Prospective studies are needed to assess if exposure independently predicts
intensity and duration of physiologic support. Access through your institution Buy or subscribe This is a preview of subscription content, access via your institution ACCESS OPTIONS Access
