母体水化疗法治疗妊娠晚期羊水过少临床疗效分析

目的:探讨母体水化疗法对妊娠晚期羊水过少患者的治疗效果。方法:将58例妊娠28～36周确诊为羊水过少(ROH)孕妇随机分为两组,每组29人。饮水疗法组采取饮水疗法,静脉补液组采取静脉补液疗法,7天后行B超复查羊水AFI值,如AFI≤8.0 cm者继续重复疗程1次,治疗后对照其羊水AFI值的变化;另选48例妊娠28～36周确诊为羊水过少患者为对照组,除加强监护外未予特殊处理。各组临产后均予阴道试产,分析比较各组试产后的分娩结局。结果:饮水疗法及静脉补液组治疗后AFI增长与治疗前相比差异有统计学意义(P<0.01)。对照组急诊剖宫产率、新生儿窒息发生率显著高于饮水疗法及静脉补液组,差异有统计学意义(P<0.05),新生儿吸入性肺炎发生率差异有统计学意义(P<0.01)。结论 :母体水化疗法对妊娠晚期无明显妊娠合并症,对ROH患者的治疗具有良好疗效,较长期的母体水化疗法能显著增加ROH患者的羊水容量,降低因羊水过少而导致的剖宫产率,减少新生儿并发症,提高围产儿结局。

Analysis on clinical effect of maternal hydration therapy for treatment of oligohydramnios during the third trimester of pregnancy

Objective:To explore the curative effect of maternal hydration therapy for treatment of oligohydramnios during the third trimester of pregnancy.Methods:A total of 58 pregnant women diagnosed as oligohydramnios definitely at 28-36 gestational weeks were randomly divided into two groups,29 women in each group.The pregnant women in hydration therapy group were treated with hydration therapy,while the pregnant women in vein fluid infusion group were treated with vein fluid infusion,AFI values in amniotic fluids were reexamined by ultrasonography after seven days,the pregnant women with AFI≤8.0 cm received therapy again,the changes of AFI values in the two groups after treatment were compared;48 pregnant women diagnosed as oligohydramnios definitely at 28-36 gestational weeks were selected as control group,they were not treated with special therapy except enhancing monitoring.Trial of labor was conducted when the pregnant women in the three groups were in labor,the delivery outcomes in the three groups were analyzed and compared.Results:There was statistically significant difference in the increase of AFI value between before and after treatment in hydration therapy group and vein fluid infusion group(P<0.01).The rate of cesarean section and the incidence of neonatal asphyxia in control group were statistically significantly higher than those in hydration therapy group and vein fluid infusion group(P<0.05);but there was statistically significant difference in the incidence of neonatal aspiration pneumonia between control group and hydration therapy group,vein fluid infusion group(P<0.01).Conclusion:Maternal hydration therapy didn’t induce obvious pregnant complications during the third trimester of pregnancy,which had good curative effect for oligohydramnios patients,long-term hydration therapy can increase the volume of amniotic fluid in patients with oligohydramnios,reduce cesarean section rate induced by oligohydramnios,reduce neonatal complications,and improve perinatal outcome.
