Amniotic fluid foam test and gastric juice oscillation test were both negative; the ratio of sphingomyelin to lecithin (L/S) in amniotic fluid was <2:1; blood pH, PaO2, and HCO3- were decreased, while PCO2 and BE were elevated, indicating metabolic acidosis. Blood potassium levels were often elevated in the early stage and could be reduced after diuresis during the recovery period. Early chest X-ray showed fine granular shadows in both lungs, while the final X-ray revealed opacity and whitening of both lungs, accompanied by a black "air bronchogram" sign. Chest X-rays should be performed before positive pressure ventilation, as recently collapsed alveoli may re-expand and result in a negative chest X-ray finding.
