摘要
应用脉冲多普勒技术测定了正常妊娠妇女和妊娠高血压综合征妇女(以下简称妊高征)各40例的脐动脉多普勒血流速波收缩期振幅/舒张期振幅(S/D)的比值和阻力指数(RI)。结果表明妊高征组中6例S/D≥3(检出率15％),7例出生儿结果不良(检出率17.5％),3例胎儿宫内发育迟缓(检出率7.5％)。说明这是一项监护高危妊娠胎儿预后的简便方法。
Fetal umbilical artery flow velocity systolic/diastolic amplitude ratio(S/D) and resistant index (RI) were measured by pulse Doppler technique in normal pregnancies (n=40) and (PIH) women (n=40). The results showed that 6/40 PIH cases had S/D ratio≥3 (ince- dence 15%); 7/4. (17. 5%) with neonatal complications and 3/40(7. 5%) with IUGR neonates. This method seems to be useful for fetal outcome predicting in high-risk pregnan- cy.
