对３６例死亡新生儿进行肺组织形态学观察，并作气管冲洗液的磷脂酰甘油（ＰＧ）检查，以验证对羊水及咽吸出物ＰＧ检查预测新生儿肺透明膜病（ＨＭＤ）的准确性。同时比较ＨＭＤ和新生儿成人型呼吸窘迫综合征（ＡＲＤＳ）的肺组织学变化，结果羊水及咽分泌物ＰＧ检查与病理诊断ＨＭＤ的符合率达１００％。
Lung morphology was observed in 36 neonatal deaths and phosphatidylglycerol (PG) examination of the tracheal irrigation fluid was performed to verify the accuracy of the PG test in predicting neonatal hyaline membrane disease (HMD) in amniotic fluid and pharyngeal aspirates . The lung histological changes of adult respiratory distress syndrome (ARDS) were compared between HMD and neonate. Results The coincidence rate of amniotic fluid and pharyngeal secretion PG with pathological diagnosis of HMD was 100%.
