Abstract
Infants with congenital heart disease (CHD) are at risk for developing both benign hematochezia and necrotizing enterocolitis (NEC). Despite these risks there are very few studies that investigate modifiable risk factors such as feeding practices. It remains unclear what feeding practices should be avoided due to higher incidence of CHD-NEC. We aim to assess the feeding practices across three high volume tertiary centers to establish a relationship between various feeding practices and development of NEC. A multicenter retrospective review of feeding practices at the time of documented hematochezia event that occurred between 1/2019 and 1/2021 in infants with CHD who were less than 6 months of age. NEC was defined as Bells Stage 2 or greater. Age, weight, ventricular morphology, primary diagnoses, feeding route, feed change, and formula type were evaluated. 176 hematochezia events occurred in 121 patients, 72% of these events were considered benign hematochezia with the remaining 28% being true NEC. Single ventricle (SV) physiology (p < 0.05), younger age, < 45 days of life, (p < 0.001), and feeding route were statistically associated with true NEC (p < 0.01). Formula type and recent change in feed administration were not associated with NEC. The caloric density of feeds at the time of hematochezia was nearing significance. The majority of hematochezia events are benign in nature, however, there should be heightened awareness in patients who are SV, younger in age, and those who are post-pylorically fed. There may be some risk in using higher caloric density feeds (> 24 kcal/oz), however, additional research is needed to fully establish this relationship.
