The measurement of palmitic acid in amniotic fluid has been shown to be a rapid means of assessing the lecithin concentration. The level of palmitic acid increases quickly when the fetal lung matures at about 35 weeks' gestation, and the level in amniotic fluid obtained 24 hours or less before delivery clearly distinguishes which infants are likely to develop respiratory distress syndrome and which are mature.
羊水棕榈酸的测量已被证明是评估卵磷脂浓度的一种快速方法。当胎儿肺在妊娠约35周时成熟,棕榈酸水平迅速升高,在分娩前24小时或更短时间内获取的羊水水平能清楚地区分哪些婴儿可能发生呼吸窘迫综合征,哪些是成熟的。
