A consecutive series of 647 routine neonatal chest x-ray films taken at a known time within 48 hours of birth was reviewed; 48% had been radiographed within 2 hours. Four hundred and twenty-seven had normal x-ray films, 147 showed evidence of delayed clearance of pulmonary fluid, and other diseases were present in 73. Excessive amounts of pulmonary fluid were not rare in neonates radiographed within 2 hours and were not necessarily associated with symptoms. Low birthweight and prematurity predisposed to delayed clearance of pulmonary fluid; with birthweights greater than 2.3 kg excess of pulmonary fluid was unlikely. Persistence of pleural fluid was more common in the right than the left lung. While radiologically there was no difference in the sex incidence of delayed clearance, symptoms were more common in boys.
回顾了连续647例在出生后48小时内已知时间拍摄的常规新生儿胸部X光片；其中48%在2小时内进行了X光检查。427例X光片正常，147例显示有肺液清除延迟的迹象，73例存在其他疾病。在2小时内进行X光检查的新生儿中，肺液过多并不罕见，且不一定伴有症状。低出生体重和早产易导致肺液清除延迟；出生体重超过2.3千克时，肺液过多的可能性较小。胸腔积液在右肺比左肺更常见。虽然在放射学上，肺液清除延迟的性别发生率没有差异，但症状在男孩中更常见。
