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。方法:对羊水过少30例患者进行回顾性分析。结果:B超对羊水量的估计准确率可达96.92%,羊水过少发生多发生于妊娠晚期,尤其是过期妊娠与之关系密切,羊水过少出现最多的并发症为妊娠期高血压疾病和胎儿生长受限;羊水过少脐带缠绕发生率明显高于对照组(P<0.05);羊水量越少,羊水粪染率、胎儿宫内窘迫发生率以及新生儿窒息率明显高于对照组(P<0.05)。结论:羊水过少一经确诊应当适时终止妊娠。 Objective: To investigate the etiology and related factors of oligohydramnios, to observe the effect of oligohydramnios on perinatal children and to find out the correct treatment method. Methods: 30 cases of oligohydramnios were retrospectively analyzed. Results: The accuracy of B-ultrasound in estimating the amount of amniotic fluid was 96.92%, oligohydramnios occurred in the third trimester, especially the out-of-phase pregnancy was closely related to the most common complications of oligohydramnios as gestational hypertension and Fetal growth restriction; oligohydramnios umbilical cord entanglement was significantly higher than the control group (P <0.05); less amniotic fluid, meconium-stained amniotic fluid, fetal distress rates and neonatal asphyxia were significantly higher than the control group P <0.05). Conclusion: oligohydramnios once diagnosed should be timely termination of pregnancy.
