B超诊断羊水偏少孕妇阴道试产120例临床分析

Analysis of 120 Cases of Trial of Labor with Borderline Oligohydramnios Assessed by Ultrasound

目的 分析足月妊娠妇女 B超检查示羊水偏少时 ,阴道试产对妊娠结局的影响。 方法 应用羊水池垂直深度 (AFD)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)及 2 4h尿雌三醇与肌酐的比值 ,比较分析 12 0例 B超诊断羊水偏少者 (观察组 )和 12 0例羊水量正常的足月妊娠妇女 (对照组 )阴道试产后的分娩结局。 结果 两组新生儿重度窒息发生率和新生儿死亡率差异无显著性 (P>0 .0 5 ) ,观察组急诊剖宫产率明显升高 (P<0 .0 1)。 结论 B超诊断羊水偏少的足月妊娠妇女 。

Objective To determine the effect of trial of labor on perinatal outcome of term pregnancy with borderline oligohydramnios. Methods Amniotic fluid deep (AFP) assessment was used to calculate the amniotic fluid volume. Systolic/diastolic ratio of the blood flow velocity in fetal umbilical arteries was examined by ultrasound. 24hours urine E 3/creatine ratio was measured. Normal amniotic fluid volume was defined as an AFD of>3.0(n=120), and borderline oligohydramnios as 2.0~3.0 cm(n=120). The perinatal outcomes after trial of labor were compared. Results No difference was found in the incidence of fetal distress and neonatal mortality between the two groups(P>0.05). The incidence of emergency cesarean section in borderline oligohydramnios group was significantly higher than that of the control group. Conclusions Patients with borderline oligohydramnios may have a trial of labor under intensive monitor.
