Case Presentation
|
|---|
A set of nonidentical twins is born at 24 weeks gestational age by normal spontaneous vaginal delivery to a 25-year-old gravida 3 para 2 female. The infants are appropriate for gestational age, weighing 525 and 520 g. Both twins are intubated in the delivery room, given surfactant via endotracheal tubes, and placed on high-frequency oscillators in the neonatal intensive care unit (NICU). Results of clinical examination on admission to the NICU are normal for both twins. On the fourth day after birth, each infant is started on continuous fentanyl infusions at 3 mcg/kg per hour. Urinary output begins to decline 24 hours after initiation of the fentanyl infusions, with a simultaneous decline in renal function (Table). On postnatal day 7, marked abdominal distention is noted in both twins.
