Human Milk-Derived Fortifier to Reduce Hospital-Acquired Malnutrition in Uncomplicated Gastroschisis: A Case Report.

Abstract

Gastroschisis is one of the most common congenital gastrointestinal disorders, occurring in about one in 1,953 infants born each year in the United States. Infants with gastroschisis rely on total parenteral nutrition (TPN) preoperatively, and due to intestinal function and dysmotility issues, continue to face feeding challenges postclosure, including feeding intolerance and increased risk of necrotizing enterocolitis (NEC). Postclosure, human milk-feeding is preferred over infant formula because of its associated reduced risk of feeding intolerance and NEC. However, unfortified human milk often falls short of meeting the increased metabolic demands of these postsurgical infants in the first few weeks of life, leading to hospital-acquired malnutrition (undernutrition) as TPN is weaned. We hypothesized that fortifying maternal milk with human milk-based fortifiers would mitigate the risk of hospital-acquired malnutrition while providing the tolerance benefits of an exclusive human milk diet, specifically by meeting the increased energy and protein demands of the immediate postsurgical infant as parenteral nutrition is weaned. The case report describes our unit's use of a human milk-based fortifier in an infant with uncomplicated gastroschisis and its positive effect on the patient's growth. Further research is warranted to assess the use of human milk-derived fortifiers to prevent hospital-acquired malnutrition after gastrointestinal surgery.
