晚期妊娠羊水过少549例临床分析

Analysis of oligohydramnio in 549 patients of later stage pregnancy.

目的分析羊水过少主要病因(合并症与并发症),探讨羊水过少对围产儿的影响,加强产前诊断与监护,发现问题及时处理,减少胎儿窘迫、新生儿窒息及围产儿死亡的发生。方法对5653例分娩总数及549例羊水过少资料进行临床分析。结果胎盘功能低下为主要原因,胎儿畸形次之;羊水过少的胎儿窘迫、新生儿窒息、围产儿死亡率及剖宫产率均高于分娩总数。结论98.5%羊水过少的妊娠晚期孕妇胎儿无畸形;妊娠晚期羊水过少确诊后,应加强产前监护,及时发现胎儿窘迫,及时处理,降低新生儿窒息率及围产儿死亡率。

Objective To investigate the main causes of oligohydramnios and its influence upon perinatal fetus, in order to improve antepartum diagnoses and monitoring, find and solve problem promptly. Methods Five hundred and forty - nine patients of oligohydramnios were selected from 5653 pregnant women in our hospital and clinical data were analysed. Results The most frequent cause of oligohydramnios was placenta dysfunction, followed by fetus malformation. Because of oligohydramnios, the incidences of fetal distress, neonatal asphyxia, cesarean delivery and perinatal fetus mortality were higher than those of normal parturition pregnant women. Conclusion 98.5% women of oligohydramnios in later stage of pregnancy, fetus are normal. If we could strengthen antepartum monitoring, find and treat fetal distress as early as possible, it is possible to reduce incidence of newborn asphyxia and perinatal fetus mortality.
