Visual diagnosis: sepsis, respiratory distress, and a persistent right lung opacification in a newborn.

摘要

A 20-year-old primigravida woman delivers a term female infant weighing 3,112 g via caesarean section under spinal anesthesia. The mother's antenatal test results are unremarkable, including a negative group B beta-hemolytic Streptococcus (GBS) screen at 33 to 34 weeks' gestation. Apgar scores are 8 and 9 at 1 and 5 minutes, respectively. Physical examination results are normal.Four hours after delivery, the infant develops tachy-pnea, grunting, and "blue" lower extremities. Supplemental oxygen is provided, blood and urine cultures are performed, and empiric treatment with intravenous am-picillin and cefotaxime is initiated. A chest radiograph reveals a normal cardiac silhouette with bilateral perihilar "streaking" of the lungs.
