目的探讨胎膜早破残余羊水量对母婴的影响。方法 446例足月胎膜早破患者,根据B超检查羊水指数将患者分为羊水过少组(84例)和羊水正常组(362例)。观察两组患者分娩方式、胎儿窘迫发生率、宫内感染发生率、羊水胎粪污染、低体重儿发生率及新生儿Apgar评分等方面等指标并进行对比。结果根据观察结果选择正确分娩方式,羊水过少组患者剖宫产占46.4%,羊水正常组患者剖宫产占20.4%,两组在分娩方式方面比较差异有统计学意义(P<0.05);羊水过少组胎儿窘迫、宫内感染、羊水胎粪污染、低体重儿发生率均高于羊水正常组,且差异有统计学意义(P<0.05);羊水过少组新生儿Apgar评分≤7指标高于羊水正常组,且差异有统计学意义(P<0.05)。结论胎膜早破且羊水过少时对妊娠影响较大,宫内胎儿状况可能危急,应在分娩过程中严格监护,保障母婴安全,提高产科质量。
Objective To investigate the effect of residual amniotic fluid volume of premature rupture of membranes on maternal and infant. Methods 446 cases of full-term premature rupture of membranes were divided into amniotic fluid oligohydramnios group (84 cases) and amniotic fluid normal group (362 cases) according to the B-mode amniotic fluid index. Observe the two modes of delivery, the incidence of fetal distress, the incidence of intrauterine infection, amniotic fluid meconium contamination, the incidence of low birth weight infants and neonatal Apgar scores and other indicators and compared. Results According to the results of observation, the correct mode of delivery was selected. Cesarean section accounted for 46.4% in patients with oligohydramnios and 20.4% in normal amniotic fluid group. There was significant difference in delivery mode between the two groups (P <0.05). The incidence of fetal distress, intrauterine infection, meconium-stained amniotic fluid, and low birth weight infants in oligohydramnios group were significantly higher than those in normal amniotic fluid group (P <0.05). Apgar score of newborns with oligohydramnios group was less than or equal to 7 The index was higher than that of normal amniotic fluid group, and the difference was statistically significant (P <0.05). Conclusion premature rupture of membranes and oligohydramnios have a greater impact on pregnancy, intrauterine fetal status may be critical, should be strictly monitored during childbirth to protect the safety of maternal and child, improve obstetric quality.
