羊水偏少孕妇阴道试产172例分析

Clinic analysis of 172 cases of trial of labor with Borderline oligohydramnios

目的分析经B超诊断羊水偏少孕足月妇女阴道试产对围产期结局的影响。方法应用羊水指数AFI法估测羊水量,并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),产前和产时胎心监护,分析比较172例B超诊断羊水偏少者(研究组)和同期180例羊水量正常的足月妇女(对照组)阴道试产的分娩结局。结果研究组剖宫产率较对照组升高明显(P<0.01);两组顺产产妇的总产程时间差异无显著性(P>0.05);两组重度新生儿窒息差异无统计学意义(P>0.05)。结论B超诊断羊水偏少的足月妊娠妇女,在严密监护下阴道试产是可行的。

Objective To analyse the effect of trial of labor with borderline oligohydramnios assessed by ultrasounography on perinatal outcome. Methods Application of the amniotic fluid index to estimate the amniotic fluid volume. Color Doppler was used to examine the systolic/diastolic ratio of t he blood flow velocity in fetal umbiheal arteries. Antenatal and intrapartum fetal monitoring was per formed. There were 172 patients with borderline oligohydramnios in research group and 180 patients with normal amniotic fluid volume in control group,The two groups were compared on perinatal outcomes as all of t he patients had trial of labor. Results The incidence of emergency section in borderline oligohydramnios group was significance higher（ P 〈 0.01 ）. There was no difference in the total time of vaginal delivery between the two groups （ P 〉 0. 05 ）. There was no difference in the incidence of neonatal mortality between the two groups（P 〉 0.05）. Conclusion The patients with borderline oligohydramnios may have a trial of labor under proper intensive care.
