目的:探讨孕产妇羊水过少出现的病因并对其进行相关数据分析,同时寻找正确的临床治疗方法,从而降低围产儿死亡率。方法:B超诊断羊水指数(AFI)和收集并估测羊水总量法确定的羊水过少的妊娠妇女,随机选择1 000例入观察组,随机选取羊水正常妇女1 000例入对照组,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:临床中羊水过少与发生分娩方式的关系统计,羊水过少的孕妇难产率显著高于对照组,差异有统计学意义(P<0.01)。在妊娠期高血压疾病、过期妊娠、妊娠期肝内胆汁淤积症、新生儿窒息、生长受限、胎儿宫内窘迫、羊水粪染、脐带绕颈、死胎等指标上,观察组的发生率高于对照组,差异皆有统计学意义(P<0.05),过期妊娠、妊娠期肝内胆汁淤积症、妊娠期高血压疾病为出现羊水过少的危险因素。结论:羊水过少因主要为胎儿因素、胎盘因素、胎膜,主要危险因素为过期妊娠、妊娠期肝内胆汁淤积症、妊娠期高血压疾病,临床上要对以上因素引起重视,积极有效地纠正羊水过少。
Objective: To explore the causes of oligohydramnios and to analyze the related data, meanwhile to find out the correct clinical treatment and reduce the perinatal mortality rate. Methods: B-ultrasonography was used to diagnose amniotic fluid index (AFI) and to collect and evaluate pregnant women with oligohydramnios determined by amniotic fluid volume method. Randomly select 1 000 cases into the observation group and randomly select 1 000 normal amniotic fluid women into the control group. Etiology, pregnancy and childbirth complications, pregnancy outcomes clinical data were analyzed. Results: The relationship between oligohydramnios and mode of delivery was statistically significant in pregnant women with oligohydramnios. The difference was statistically significant (P <0.01). The incidence rate of observation group was high in hypertensive disorders of pregnancy, obstetric pregnancy, intrahepatic cholestasis of pregnancy, neonatal asphyxia, growth restriction, fetal distress, meconium-stained amniotic fluid, cord around the neck and stillbirth In the control group, the difference was statistically significant (P <0.05), obese pregnancy, intrahepatic cholestasis of pregnancy, hypertensive disorder of pregnancy as a risk factor for oligohydramnios. Conclusion: The oligohydramnios are mainly due to fetal factors, placental factors, fetal membranes, the main risk factors for the out-of-pregnancy, intrahepatic cholestasis of pregnancy, hypertensive disorders of pregnancy, the clinical should pay attention to these factors, and actively and effectively Correct oligohydramnios.
