Like Mother, Like Daughter: Feeding Intolerance in the NICU.

A female infant is born at 35 weeks, 4 days of gestation to a 29-year-old gravida 1, para 1 mother via cesarean section because of a footling breech presentation. The mother had received adequate prenatal care and had normal ultrasonography scans except for the finding of a 2-vessel cord and an infant who was small for gestational age. Maternal infectious laboratory findings are negative. Delivery is uneventful and Apgar scores at 1 minute and 5 minutes are 7 and 9, respectively. The infant’s birthweight is 1,920 g (0.35%, Z −2.69), birth length is 44.5 cm (1.46%, Z −2.18), and head circumference is 29.8 cm. (0.02%, Z −3.6) Around 85 minutes after birth, because of jitteriness, the infant’s blood glucose (BG) is measured and found to be 21 mg/dL (1.17 mmol/L). She is offered preterm infant formula 22 kcal/oz, of which, she took around 10 mL, and repeat BG is found to be 27 mg/dL (1.5 mmol/L). A peripheral intravenous catheter is placed and a 2 mL/kg bolus of 10% dextrose (D10) given, and an infusion of D10 in water at the rate of 80 mL/kg per day is started. Repeat BG is 88 mg/dL (4.9 mmol/L). On day 2 after birth, she starts having choking episodes and nonbilious emesis with feeding. Abdominal radiography shows a nonobstructive bowel gas pattern. She is transferred to the NICU and a nasogastric (NG) tube placed for feeding. Her BG levels remain stable with NG feedings, and she continues to be in room air with no evidence of respiratory distress. A sepsis evaluation is completed, with rule-out antibiotics (ampicillin and gentamycin) for 48 hours, with negative findings noted on culture. Echocardiography and head ultrasonography findings are normal, renal ultrasonography shows normal kidneys and a questionable bicornuate uterus. Physical examination findings are otherwise normal except for …
