足月妊娠羊水偏少200例临床分析

Clinical analysis of 200 cases of borderline oligohydramnios in full-term pregnancy

目的探讨足月妊娠羊水偏少对新生儿结局的影响。方法选择200例足月妊娠羊水偏少患者为观察组,同期154例羊水过少患者及191例羊水量正常孕妇为对照组,比较三组不同分娩方式下新生儿异常情况的发生率。结果羊水偏少组及羊水过少组新生儿异常发生率均高于羊水正常组(x^2=0.001,P<0.05),但羊水偏少组与羊水过少组新生儿异常发生率无统计学差异(x^2=0.978,P>0.05);不同分娩方式羊水偏少组与羊水过少组新生儿异常发生率无统计学差异(x^2值分别为0.103、0.117,均P>0.05);羊水偏少组与羊水过少组发生羊水污染者不同分娩方式新生儿异常情况无统计学差异(x^2值分别为0.804、0.151,均P>0.05)。结论足月妊娠羊水偏少不容忽视,同样易导致围产儿异常,阴道试产时应密切观察产程进展。

Objective To investigate the influence of borderline oligohydramnios with full-term pregnancy on neonatal outcomes .Methods Two hundred cases of full-term pregnancy with borderline oligohydramnios were selected as observation group , and 154 cases of oligohydramnios patients and 191 cases with normal amniotic fluid volume over the same period were selected randomly as control groups . The incidence of neonatal abnormalities was compared among three groups .Results The incidence of neonatal abnormalities in the patients of borderline oligohydramnios and those of oligohydramnios was significantly higher than in the cases with normal amniotic fluid volume （χ2 =0.001,P〈0.05）, but the difference between observation group and oligohydramnios group was not significant （χ2 =0.978,P〈0.05）.Different delivery modes showed no significant difference in the incidence of neonatal abnormalities between borderline oligohydramnios and oligohydramnios groups （χ2 value was 0.103 and 0.117, respectively, both P〈0.05）.By different delivery modes, observation group and oligohydramnios group with meconium-stained fluid had no significant difference in the incidence of neonatal abnormalities （χ2 value was 0.804 and 0.151, respectively, both P 〈0.05 ）.Conclusion Full-term pregnancy with borderline oligohydramnios should not be ignored , and it also has severe impact on perinatal outcomes .Progress of vaginal delivery should be observed closely.
