Randomized Controlled Trial of Early Enteral Fat Supplement and Fish Oil to Promote Intestinal Adaptation in Premature Infants with an Enterostomy

Abstract

To test the hypothesis that early enteral supplementing fat and fish oil decreases the duration of parenteral nutrition (PN) and increases enteral nutrition (EN) before bowel reanastomosis in premature infants with an enterostomy. Premature infants (<2 months old) who had an enterostomy and tolerated enteral feeding at 20 mL/kg/day were randomized to usual care (control=18) or early supplementing enteral fat supplement and fish oil (treatment=18). Intravenous lipid was decreased as enteral fat intake was increased. Daily weight, clinical and nutrition data, and weekly length and head circumference were recorded. The primary outcomes were the duration of PN and volume of EN intake, and the secondary outcomes were weight gain (g/day), ostomy output (mL/kg/d), and serum conjugated bilirubin level (mg/dL) from initiating feeding to reanastomosis. Data were analyzed by Student t test or Wilcoxon rank sum test. There were no differences in the duration of PN, ostomy output, and weight gain between the 2 groups before reanastomosis. However, supplemented infants received less intravenous lipid, had greater EN intake, and lower conjugated bilirubin before reanastomosis, and they also received greater total calorie, had fewer sepsis evaluations and less exposure to antibiotics and central venous catheters before reanastomosis, and had greater weight and length gain after reanastomosis (all P<.05). Early enteral feeding of a fat supplement and fish oil was associated with decreased exposure to intravenous lipid, increased EN intake, and reduced conjugated bilirubin before reanastomosis and improved weight and length gain after reanastomosis in premature infants with an enterostomy.
