What Is The Understanding Of Brain Development In The PDA Gestation?

Decent Essays

Imagine a one-week-old infant born prematurely at 32 weeks gestation undergoing a PDA ligation receiving only a paralytic, without any anesthesia or analgesia. This was commonplace for invasive procedures in neonates throughout most of the 19th century, up until the mid 1980’s when the reality of pain perception in the neonate gained awareness. We now know that pain and stress associated with standard procedures in the intensive care unit have been associated with impaired brain maturation [. The use of analgesics and sedatives have become commonplace in the neonatal population; however, these important medications are not without inherent risk.

Just as technological interventions have developed over the decades, so has our …show more content…

Exposure to analgesics in NICU populations is increasing over time. Lewis et al conducted a retrospective cross-sectional cohort study quantifying trends in opiate exposure in a tertiary care NICU over the course of 8 years. Similar high-risk infant cohorts were evaluated for cumulative opiate exposure over distinct time periods: 2003-2004, 2007-2008, and 2010-2011. A steep rise in opiate exposure per infant was noted with an increase of 134 mg per time period. There was a statistically significant increase in the infants diagnosed with iatrogenic NAS from 9% to 50% (p=0.012) (Lewis et al). In 2017, Zimmerman et al published a study evaluating drug administration to infants < 1500 grams and < 32 weeks gestation on mechanical ventilation. The researchers found an increase in the administration of opioids from 5% of infant days in 1997 to 32% of infant days in 2012. The site of hospitalization was an independent predictor of drug administration, even after adjustments were made for infant characteristics, suggesting that local practice is a significant predictor of analgesic use. Identifying a trend in site-specific factors influencing the variability in administration of these potent medications highlighted the importance of quality improvement measures to move administration based on local practice towards analgesic administration based on infant characteristics (Zimmerman et
