目的探讨羊水过少的病因及相关因素,观察羊水过少对围生儿的影响,寻找正确的处理方法,降低围生儿病死率。方法对羊水过少142例患者的临床资料进行回顾性分析。结果B超对羊水量的估计准确率可达97.13%,羊水过少发生率为3.62%,且多发生于妊娠晚期,过期妊娠与之关系尤其密切,羊水过少组(观察组)明显高于正常产妇组(对照组)(P<0.01),胎儿生长受限及妊娠期高血压疾病者多发生于孕37～40周。羊水粪染、胎儿宫内窘迫、新生儿窒息及剖宫产率均明显高于对照组,差异有统计学意义(P<0.01)。结论羊水过少一经确诊应适时终止妊娠,且以剖宫产为宜。
Objective To investigate the etiology and related factors of oligohydramnios, to observe the impact of oligohydramnios on perinatal children, to find the correct treatment and reduce perinatal mortality. Methods The clinical data of 142 patients with oligohydramnios were retrospectively analyzed. Results The accuracy of B-ultrasound in estimating amniotic fluid volume was 97.13%, the incidence of oligohydramnios was 3.62%, and occurred more frequently in late trimester. The relationship of overdue pregnancy was particularly close, and the oligohydramnios group (observation group) was significantly higher than The normal maternal group (control group) (P <0.01), fetal growth restriction and hypertensive disorder complicating pregnancy occurred in 37 to 40 weeks. Stool amniotic fluid, fetal distress, neonatal asphyxia and cesarean section rate were significantly higher than the control group, the difference was statistically significant (P <0.01). Conclusions After oligohydramnios have been diagnosed, the pregnancy should be terminated timely and cesarean section should be appropriate.
