目的:探讨围生期羊水过少对围产结局的影响。方法:应用B超羊水指数法和直接测量估测羊水量及测定脐动脉收缩期最大血流速度(S)和舒张末期血流速度(D)的比值(S/D),并进行胎儿无应激试验(NST)监护,比较分析羊水过少组(观察组)和羊水正常组(对照组)的妊娠并发症、围产儿情况、分娩方式、羊水混浊及羊水量、羊水混浊与胎儿缺氧关系。结果:观察组的妊高征、过期妊娠、胎儿宫内发育迟缓、胎儿畸形等妊娠并发症发生率均明显高于对照组(均P<0.01);观察组的胎儿宫内窘迫、新生儿窒息、吸入性肺炎的发生率均明显高于对照组(均P<0.05);观察组的剖宫产率和羊水混浊发生率均明显高于对照组(均P<0.01);观察组的羊水量愈少,羊水混浊程度愈严重,胎儿宫内窘迫及新生儿窒息发生率愈高。结论:羊水过少的孕妇围产结局取决于羊水指数值、羊水混浊程度、S/D比值、胎儿电子监护NST结果及分娩方式。加强对羊水过少的产前监护是非常重要的,剖宫产是重度羊水过少孕妇分娩方式的最佳选择。
Objective: To investigate the effect of perinatal oligohydramnios on perinatal outcome. Methods: The amniotic fluid volume and the ratio of the maximum (S) and end-diastolic blood flow (D) of umbilical artery were measured by B-amniotic fluid index method and direct measurement, (NST), and compared the pregnancy complications, perinatal conditions, mode of delivery, amniotic fluid opacity and amniotic fluid volume, amniotic fluid turbidity and fetal hypoxia in oligohydramnios group (observation group) and amniotic fluid normal group (control group) . Results: The incidences of pregnancy complications such as pregnancy-induced hypertension syndrome, obstetric pregnancy, intrauterine growth retardation and fetal malformation in the observation group were significantly higher than those in the control group (all P <0.01). The fetal distress, neonatal asphyxia , And the incidence of aspiration pneumonia were significantly higher than those in the control group (all P <0.05). The incidences of cesarean section and amniotic fluid turbidity in the observation group were significantly higher than those in the control group (all P <0.01) The less, the more severe the degree of cloudy amniotic fluid, fetal distress and neonatal asphyxia the higher the incidence. CONCLUSION: Perinatal outcome of pregnant women with oligohydramnios depends on amniotic fluid index, amniotic fluid turbidity, S / D ratio, fetal electronic monitoring NST results, and mode of delivery. To strengthen the prenatal care of oligohydramnios is very important, cesarean section is too much oligohydramnios pregnant women best choice of mode of delivery.
