Variation in opioid utilization among neonates with gastroschisis.

PURPOSE:Repetitive painful stimuli and early exposure to opioids places neonates at risk for neurocognitive delays. We aimed to understand opioid utilization for neonates with gastroschisis. METHODS:We performed a retrospective review of infants with gastroschisis at a tertiary children's hospital (2017-2019). Multivariate linear regression was performed to analyze variations in opioid use. RESULTS:Among 30 patients with gastroschisis, 33% were managed by primary suture-less closure, 7% by primary sutured closure, 40% by spring silo, and 20% by handsewn silo. The proportion of pain medication used was: morphine (89%), acetaminophen (8%), and fentanyl (3%). Opioids were used for a median of 6.5 days (range 0-20) per patient. Median total opioid administered across all patients was 2.2 morphine milligram equivalents (MME)/kg (IQR 0.7-3.3). Following definitive closure, median opioid use was 0.2 MME/kg (IQR 0.1-0.8). With multivariate regression, 45% of the variation in MME use was associated with the type of surgery after adjusting for weight, gestational age, and gender, p = 0.02. After definitive fascial closure, there was no significant variations in opioid use. CONCLUSION:There is a significant variation in the utilization of opioid, primarily prior to fascial closure. Understanding pain needs and standardization may improve opioid stewardship in infants with gastroschisis. 197/200 LEVEL OF EVIDENCE: Level III.
