A method for rapid determination of total esterified palmitic acid concentration (TEPAC) in amniotic fluid is described. The correlation coefficient between the TEPAC and the lecithin concentration was 0.93 in 123 samples of amniotic fluid obtained during the last trimester. The respiratory distress syndrome (RDS) occurred in 73% of the cases studied with TEPAC less than mmol/l in predelivery samples. The RDS was not observed with higher concentrations except in cases of maternal diabetes mellitus. The predictive value of total esterified fatty acid studies was confirmed to the concentration of palmitic acid recorded, and no specific fatty acid distributions or ratios were reliable in identifying RDS or estimating gestational age.
本文描述了一种快速测定羊水总酯化棕榈酸浓度（TEPAC）的方法。在妊娠晚期采集的123份羊水样本中，TEPAC与卵磷脂浓度之间的相关系数为0.93。在分娩前样本中，TEPAC低于mmol/l的研究病例中有73%发生了呼吸窘迫综合征（RDS）。除了患有妊娠糖尿病的病例外，在较高浓度下未观察到RDS。总酯化脂肪酸研究的预测价值与记录的棕榈酸浓度得到了证实，并且在识别RDS或估计胎龄方面，没有特定的脂肪酸分布或比例是可靠的。
