我院１９９２年１～１２月头位生产羊水胎粪污染４１６例，发生率２１．９％，早产及过期妊娠羊水粪染发生率显著高于足月产（Ｐ＜０．００５）．羊术Ⅲ度粪染者胎心电子监护异常及新生儿不良结局的发生率均显著高于Ⅰ度与Ⅱ度粪染者（Ｐ＜０．００５）．９例胎粪吸入综合征，有７例为羊水Ⅲ度粪染．脑心电子监护异常组新生儿不良结局发生率明显高于胎业正常和仅有胎心基线变异减少或消失组（Ｐ＜０．００５），阳性预测率６７．０３％．本研究结果提示，羊水Ⅲ度粪染有明确的胎儿宫内窘迫，应尽快娩出胎几，Ｉ度与Ⅱ度羊水粪染，应加强胎心电子监护，不必过早干预．早产羊水粪染发生率高不支持“胎粪排出乃胎儿肠道成熟标志”的理论． 416 cases of meconium-stained amniotic fluid were produced in our hospital from January to December in 1992, with a incidence of 21.9%. The incidence of amniotic fluid meconium in preterm and outdated pregnant women was significantly higher than that in full term (P <0.005). Abnormal fetus heart rate monitoring and neonatal adverse outcomes in ovariectomy were significantly higher than those in grade Ⅰ and Ⅱ (P <0.005). 9 cases of meconium aspiration syndrome, 7 cases of amniotic fluid Ⅲ degree meconium staining. The incidence of neonatal unhealthy outcomes in abnormal brain-ECG monitoring group was significantly higher than that in normal fetus industry and only in the reduction or disappearance of baseline fetal heart rate variability (P <0.005). The positive predictive rate was 67.03%. The results of this study suggest that amniotic fluid Ⅲ degree meconium stained clear fetal distress should be delivered as soon as possible a few fetal I, degree Ⅱ and amniotic fluid meconium staining should be enhanced fetal heart electronic monitoring, without premature intervention. Preterm high incidence of meconium-stained amniotic fluid does not support the “meconium discharge is a sign of fetal intestinal maturity,” the theory.
