目的探讨妊娠晚期羊水过少的相关因素及其对围生儿的影响。方法将148例妊娠晚期羊水过少产妇作为观察组,随机选择148例羊水量正常产妇作为对照组,将两组产妇临床资料进行回顾性分析。结果超声诊断羊水过少的临床符合率为95.77%;观察组过期妊娠、宫内生长迟缓、妊娠期高血压疾病及胎盘钙化发生率与对照组比较差异具有统计学意义(P均<0.05)。观察组中羊水Ⅲ度污染、胎儿宫内窘迫、剖宫产及新生儿窒息发生率明显高于对照组(P均<0.05)。结论超声检查是及时发现羊水过少的可靠方法;羊水过少对围生儿的影响严重,一旦确诊,应严密监测胎心、胎动及羊水变化,适当放宽剖宫产指征。
Objective To investigate the related factors of oligohydramnios in late pregnancy and its effect on perinatal children. Methods 148 cases of oligohydramnios in late trimester of pregnancy as the observation group, 148 cases of normal amniotic fluid as a normal control group, the clinical data of two groups were retrospectively analyzed. Results The clinical coincidence rate of ultrasonography diagnosis of oligohydramnios was 95.77%. The observation group had statistically significant differences (P <0.05) in the incidence of over-pregnancy, intrauterine growth retardation, gestational hypertension and placental calcification. Amniotic fluid Ⅲ degree of pollution in the observation group, fetal distress, cesarean section and neonatal asphyxia were significantly higher than the control group (P all <0.05). Conclusions Ultrasonography is a reliable method to detect oligohydramnios in time. Too little oligohydramnios has a serious impact on perinatal children. Once confirmed, fetal heart rate, fetal movement and amniotic fluid changes should be closely monitored, and cesarean indications should be appropriately relaxed.
