摘　　要：目的 :探讨脐血流阻力指标 (S/D、PI、RI)在正常与高危妊娠中的变化及其与围产儿预后的关系。方法 :1998年 3月至 1999年 3月住院的正常与高危产妇共计 110例 ,均于产前 1周内行多普勒超声检查 ,并统计相关临床资料。结果 :高危妊娠时脐血流阻力指数较正常时明显升高 ,各组中S/D值超过警戒值 (2 .2 0 )及危险值 (2 .6 6 )者围产儿预后不良发生率较S/D值正常者显著升高。结论 :彩色多普勒超声测定脐血流阻力指数是一种简便、无创、有效的围产期监测手段 ,以S/D值 2 .2 0为警戒线 ;S/D值 2 .6 6为危险线可能更有助于胎儿缺氧的早期诊断 。Aim: To investigate the variation of resistant parameters of fetal umbilical artery blood flow in normal and pathologic pregnancy and its relationship with the perinatal outcome. Methods: Fetal umbilical artery blood flow in 110 cases of the normal and patients were examined within one week before labour while their clinical material statistics were collected. Results:In pathologic pregnancy,the umbilical artery blood flow parameter (S/D) was significantly higher than that of normal pregnancy and the incident rate of the adverse perinatal outcome was higher when compared with the S/D normal group, S/D guarding group and S/D abnormal group. Conclusion: Fetal umbilical blood flow velocity parameters using doppler ultrasonography is a simple, no wounded and efficient method in perinatal control and set S/D guarding line as 2.20, dangerous line as 2.66 has clinical meaning in diagnosis of intrauterine hypoxia.
