A 4-day-old boy who was born by uncomplicated vaginal delivery to a primigravid mother at an estimated gestational age of 40 weeks and 1 day presented with recurrent episodes of tachypnea, suprasternal retractions, stertorous nasal breathing, and bilateral medial canthal edema with bluish discoloration. His antenatal and birth history were remarkable for polyhydramnios of unknown etiology and respiratory depression requiring neonatal resuscitation. Apgar scores at 1, 5, and 10 minutes were 1, 8, and 9, respectively, and the patient was breathing well on room air by 5 minutes of life. After initial resuscitation, there was no cyanosis or need for supplemental oxygen.
