    Influence of oligohydramnios at late pregnancy on perinatal infants and analysis of the related factors

    • 摘要: 目的:探讨妊娠晚期羊水过少对围生儿的影响及相关因素。方法:对121例妊娠晚期羊水过少孕妇进行分析,并与羊水量正常分娩者进行比较。结果:在孕≥ 42周者中,羊水过少的发生率为13.51%,在孕40+1~41+6周者为4.28%,在孕37~40周者为2.86%,在<37周者为2.21%;在妊娠合并症者中为24.79%。羊水过少组剖宫产、胎儿窘迫及羊水Ⅱ~Ⅲ度粪染发生率较均对照组高(P<0.01),且羊水量越少,羊水粪染及胎儿窘迫发生率越高(P<0.01)。羊水过少组新生儿窒息发生率与对照组差异无统计学意义(P>0.05)。结论:羊水过少与延期或过期妊娠及妊娠并发症关系密切,它严重威胁围生儿生命,造成不良妊娠结局。发现羊水过少后,应适时终止妊娠,可分娩者以剖宫产为宜,可改善围生儿预后。

       

      Abstract: Objective: To analyze the influence of oligohydramnios at the late pregnancy on the perinatal infants and the related factors.Methods: A total of 121 cases of oligohydramnios were analyzed and compared with those with normal amniotic fluid.Results: Thirteen point fifty-one percent oligohydramnios occurred in cases exceeding 42 gestational weeks,4.28%in cases with 40+1-41+6 gestational weeks,2.86% in cases with 37-40 gestational weeks and 2.21% in cases under 37 gestational weeks.The occurrence of oligohydramnios was 24.79% in cases with high risk pregnancy.The rate of cesarean section,fetus predicament and Ⅱ-Ⅲ grade amniotic fluid affection in the oligohydramnios group was higher than that in the control group(P<0.01).The volume of oligohydramnios was negatively related to the rate of cesarean section and fetus predicament(P<0.01).The rate of rebirth stifling in the oligohydramnios group was higher than that of the control group,but the difference was not obvious(P>0.05).Conclusions: Oligohydramnios is closely associated with prolonged pregnancy and other related complications,which gravely threatens the life of perinatal infants.Therefore,timely termination of pregnancy or caesarean section is suggested to cases with oligohyrdramnios.
