足月妊娠羊水过少122例临床分析

Clinical analysis of 122 full-term pregnancy cases with oligohydramnios

目的：探讨羊水过少发生的相关因素及对围生儿的影响。方法：对足月妊娠羊水过少的122例孕妇的临床资料进行回顾性分析,并随机抽取同期足月妊娠羊水量正常的孕妇122例作为对照。结果：足月妊娠羊水过少随着孕周的增加其发生率增高（P〈0.01）;羊水过少组妊娠并发症、胎儿宫内窘迫、新生儿窒息、无应激性试验时出现晚期减速、可变减速、羊水污染、吸入性肺炎发生率均高于羊水正常组（P〈0.05-P〈0.01）;且剖宫产率较羊水正常组高（P〈0.01）。结论：羊水过少是胎儿危险的重要信号,一经诊断,应以剖宫产分娩为宜。

Objective： To explore the related factors of oligohydramnios and its effect on the peninatal infant. Methods： The clinical data of 122 full-term pregnancy cases with oligohydramnios were retrospectively analyzed. The 122 full-term pregnancy women with normal amniotic fluid volume were set as the control group. Results： With the increasing of gestational weeks,the incidence of oligohydramnios in full-term pregnancy cases increased（ P〈0. 01）. The pregnancy complications,fetal distress,neonatal asphyxia,late deceleration at non-stress test,variable deceleration,amniotic fluid pullution and aspiration pneumonia in oligohydramnios group were higher than those in control group（ P〈0. 05 to P〈0. 01）. The cesarean section rate in oligohydramnios group was higher than that in normal group（ P〈0. 01）. Conclusions： Oligohydramnios is an important signal of fetal risk,and upon diagnosis,the cesarean section should be implemented.
