B超诊断羊水过少及其临床意义

Diagnosis of ologohydramnio with ultrasonics and its clinical significance

目的:分析足月妊娠时 B超产前诊断羊水过少的方法及标准 ,以及羊水过少对围产期结局的影响。 方法 :选择超声检查羊水量少、37～ 42孕周的 118例孕妇 ,测定羊水最深值 (AFD)及羊水指数 (AFI) ,与产时实际测得羊水量进行对照 ,并比较分析羊水过少组与羊水适量组的围产期结局。结果:实际羊水量随着 AFD及 AFI值的增加而增加 ,并且后两者结合可明显提高羊水过少的诊断准确率 ,两组分娩方式及新生儿轻度窒息率差异有显著性 (P <0 .0 5 )。 结论:B超诊断羊水过少是比较可靠的方法 。

Objective: To evaluate the diagnostic method and criterion of oligohydramnio in normal term gestation with ultrasonographic measurements and understand the effect of oligohydramnio to pregnant outcome. Methods: 118 gravida were measured aminiotic fluid depth (AFD) and aminiotic fluid index (AFI) and collected actural aminiotic fluid while delivery. To compare the pregnant outcome between the groups of oligohydramnio and the control. Results: Actural aminiotic grow with higher AFD and AFI; Combination AFD and AFI will enhance diagnostic rate of oligohydramnio. Both groups showed significant difference in delivery way and new born suffocation (P<0.05). Conclusions: Diagnosis of oligohydramnio by ultrasonics is a reliable method and the gravida with oligohydramnio can be nature delivered through vagina under strict supervision by midwives or doctors.
