A 12-hоur-оld infаnt wаs trаnsferred fоr admission to the university hospital neonatal intensive care unit for respiratory problems after being born at a community hospital by vaginal delivery to a woman who had just completed her 39th week of pregnancy. The infant was exhibiting respiratory symptoms consistent with aspiration of meconium at the time of the delivery. The infant had low Apgar scores of 5 and 6 with tachypnea and cyanosis. On admission, the infant was intubated and placed on mechanical ventilation and maintained on it for 48 hours. Within one day, the infant’s chest x-ray demonstrated patchy infiltrates. The neonatologist diagnosed the infant as having meconium aspiration pneumonia with no signs of pulmonary hypertension as a consequence of the pneumonia. The physician also described the infant as “small for dates,” weighing 2,200 grams. Principal Diagnosis: Secondary Diagnosis: Principal Procedure: Secondary Procedure:
