目的分析足月孕产妇羊水过少的有效分娩方式。方法 100例足月孕产妇根据羊水量分为观察A组(临界性羊水过少)与观察B组(绝对羊水过少),各50例;另选取同期50例羊水量正常的足月孕产妇为对照组。观察三组孕产妇阴道试产成功率、急诊剖宫产率以及围生儿结局。结果观察B组孕产妇阴道分娩率48.0%,明显低于观察A组68.0%与对照组的84.0%;急诊剖宫产率52.0%明显高于观察A组32.0%与对照组的16.0%,差异均具有统计学意义(P<0.05)。观察B组的羊水污染率、胎儿窘迫率、新生儿窒息率均明显高于其他两组,差异均具有统计学意义(P<0.05)。结论临床不应完全将临界性羊水过少纳入剖宫产指征,而应严格阴道分娩指征,对胎儿情况予以密切监测,并采取正确的应对处理措施,则可提高阴道试产可行性与成功率;但对于绝对羊水过少的孕产妇而言,应谨慎选择阴道分娩方式。
Objective To analyze the effective mode of delivery of oligohydramnios in term pregnant women. Methods 100 full-term pregnant women were divided into observation group A (borderline oligohydramnios) and observation group B (absolute polyhydramnios) according to the amniotic fluid volume, each 50 cases. Another 50 pregnant women with full-term amniotic fluid of the same period For the control group. Observe the success rate of three groups of pregnant women vaginal trial production, emergency cesarean section rate and perinatal outcome. Results The vaginal delivery rate of pregnant women in Group B was 48.0%, significantly lower than 68.0% in Group A and 84.0% in Control Group. The rate of cesarean section in emergency group was 52.0%, significantly higher than that in Group A 32.0% and control group 16.0% All were statistically significant (P <0.05). Amniotic fluid contamination rate, fetal distress rate and neonatal asphyxia rate in group B were significantly higher than those in other two groups (P <0.05). Conclusions Clinically, the indication of cesarean section should not be completely included in the study, but indications of vaginal delivery should be strictly observed, and the fetus should be closely monitored and the correct response measures should be taken to improve the feasibility of vaginal trial production Success rate; but for the absolute number of maternal oligohydramnios, should be carefully chosen vaginal delivery.
