作者介绍一种简易迅速的方法以测定胎儿肺成熟度。此种方法系采用巴斯德毛细吸管吸取20μl羊水放置于Whatman纤维素滤纸上以测定其流速时间。作者从70例患者的羊膜腔穿刺中获得81份羊水标本。标本按不同孕周(16～38周)进行收集以供试验,如发现羊水内有血液或胎粪则废弃不用。一般在收集羊水后1小时内进行试验,同时用Clements等的震荡试验作对照,取羊水20μl放入有刻度的巴斯德吸管内,垂直位轻放于Whatmen滤
The authors describe a quick and easy way to determine fetal lung maturity. This method is the use of Pasteur capillary pipet 20μl amniotic fluid placed on Whatman cellulose filter paper to determine the flow time. The authors obtained 81 amniotic fluid samples from amniocentesis in 70 patients. Specimens according to different gestational age (16 to 38 weeks) collected for testing, such as found in amniotic fluid or meconium was discarded without. General collection of amniotic fluid within 1 hour after the test, at the same time with Clements and other shock test for control, taking 20μl of amniotic fluid into a graduated Pasteur pipette, placed in the vertical position Whatmen filter
