Perioperative nutrition in extremely preterm infants undergoing surgical treatment for patent ductus arteriosus is suboptimal

• AIM: To evaluate perioperative nutrition in extremely preterm infants undergoing surgery for patent ductus arteriousus (PDA).METHODS: Population-based study of extremely preterm infants born in Sweden during 2004-2007 and operated on for PDA. Data on perioperative nutrition was obtained from hospital records. All enteral and parenteral nutrients and blood products were used to calculate daily nutritional intakes, starting three days before and ending three days after surgery. Data are mean (95% confidence intervals).RESULTS: Study infants (n=140) had a mean gestational age of 24.8 weeks and mean birth weight was 723 gram. Energy and macronutrient intakes were below minimal requirements before, during and after PDA surgery. On the day of surgery, energy intake was 78(74-81) kcal/kg/d, protein 2.9(2.7-3.2) g/kg/d, fat 2.5(2.3-2.7) g/kg/d and carbohydrate intake was 10.7(10.2-11.2) g/kg/d. Nutrition did not vary in relation to GA, but infants operated early (0-6 days after birth) received poorer nutrition than infants operated at older age. Fluid intake was 164(159-169) mL/kg/d, and it did not vary during the week of surgery.CONCLUSIONS: Perioperative nutrition in extremely preterm infants undergoing PDA surgery in Sweden is suboptimal and needs to be improved. The significance of malnutrition for outcome after PDA surgery remains unclear and requires further investigation.
