羊水泡沫试验或称振荡试验可作为胎儿肺成熟度指标用于予测胎儿娩出后患 HMD(肺透明膜病)之危险程度。肺表面活性物质浓度高时试验呈阳性反应,不出现 HMD;浓度低或无呈阴性,易患 HMD,试验无假阳性但有假阴性。作者对410例婴儿所患 HMD 与其产前泡沫试验结果之间的关系作了研究。羊水标本取自妊娠晚期孕妇,经腹或经阴道羊膜腔穿刺而得,含血、胎粪者弃之。离心取上清液,与等量之95%酒精混匀于试 Amniotic fluid foam test or oscillation test can be used as a marker of fetal lung maturity to predict the risk of fetal HMD (hyaline membrane disease) after delivery. High concentrations of pulmonary surfactant test positive test, no HMD; low concentration or no negative, susceptible to HMD, the test without false positive but false negative. The authors studied the relationship between HMD in 410 infants and the results of their prenatal foam test. Amniotic fluid specimens taken from pregnant women in late pregnancy, transabdominal or transvaginal amniotic puncture derived, blood, meconium were abandoned. Centrifuge the supernatant, and the same amount of 95% alcohol mixture in the test
