Neonates with critical congenital heart defects (CCHD neonates) experience high rates of feeding intolerance, necrotizing enterocolitis (NEC), and malnutrition. The benefits of human milk and direct chest/breastfeeding are well known, but research is limited in CCHD neonates. Therefore, the purpose of this study is to examine the impact of neonatal diet and feeding modality on the incidence of feeding intolerance, NEC, and malnutrition among a cohort of CCHD neonates.
A single-center retrospective study was conducted using electronic health record data of CCHD neonates admitted to a cardiac intensive care unit between April 2016 and April 2020. Regression models were fit to analyze associations between neonatal diet, feed modality, and adverse feeding outcomes.
Seventy-four CCHD neonates were included. Increased days of direct chest/breastfeeding were associated with fewer signs of gastrointestinal distress (P = .047) and bloody stools (P = .021). Enteral feeding days of "all human milk" were associated with higher growth trajectory (P < .001).
Human milk and direct chest/breastfeeding may be protective against some adverse feeding outcomes for CCHD neonates. Larger, multicenter cohort studies are needed to continue investigating the effects of neonatal diet type and feeding modality on the development of adverse feeding outcomes in this unique population.
