目的探讨羊水过少的病因及相关因素,寻找正确的处理方法,降低围生儿死亡率。方法对我院2000年1月-2007年3月住院分娩中1256例羊水过少及同期19882例非羊水过少病例从病因、妊娠及分娩期并发症、妊娠结局的临床资料进行对照分析。结果B超对羊水量的估计准确率可达到97%;羊水过少的妊娠并发症如妊高征、胎儿宫内发育迟缓(IUGR)、过期妊娠、胎儿畸形等。胎儿窘迫及新生儿窒息率明显高于对照组,难产率也明显高于对照组,差异均有统计学意义(P<0.01)。结论积极寻找病因纠正羊水过少,适时终止妊娠是本次妊娠的最佳选择。
Objective To investigate the etiology and related factors of oligohydramnios, to find the correct treatment method to reduce perinatal mortality. Methods The clinical data of 1256 cases of oligohydramnios and 19882 cases of non-oligohydramnios in our hospital from January 2000 to March 2007 in our hospital from etiology, pregnancy and childbirth complications and pregnancy outcome were analyzed. Results The accuracy of B-ultrasound in estimating the amount of amniotic fluid can reach 97%. The complications of oligohydramnios such as pregnancy-induced hypertension syndrome, intrauterine growth retardation (IUGR), overdue pregnancy, fetal malformation and so on. Fetal distress and neonatal asphyxia rate was significantly higher than the control group, dystocia rate was also significantly higher than the control group, the difference was statistically significant (P <0.01). Conclusion Actively looking for the cause of correction of oligohydramnios, timely termination of pregnancy is the best choice for this pregnancy.
