北京妇产科医院丛克家等应用桡动脉血流图对95例14～38孕周孕妇进行妊高征的预测。结果预测符合率达85.7％,高于孕中期平均动脉压和翻身试验方法。后又加用心功能参数外周阻力和波形系数K值对120例孕妇进行预测,使预测方法更为准确。临床对预测阳性者予以生活指导,使妊高征的发病率由18.9％降至9.2％ Beijing Obstetrics and Gynecology Hospital, such as Cong Ke family radial artery flow diagram of 95 cases of 14 to 38 gestational weeks pregnant women predict pregnancy-induced hypertension. Results The predictive compliance rate was 85.7%, higher than the mean arterial pressure in the second trimester and the stand-up test method. After adding heart function parameters of peripheral resistance and waveform factor K value of 120 cases of pregnant women to predict, the prediction method is more accurate. The clinical prediction of life-giving positive guidance, so that the incidence of PIH decreased from 18.9% to 9.2%
