为比较先兆子痫与正常妊娠母体脑血循环情况 ,作者选择2 6例先兆子痫 ,11例妊娠高血压综合征 (PIH)和 17例正常妊娠妇女 ,均为晚期妊娠。于高血压治疗前 ,记录颈内、颈外和大脑中动脉多普勒波形 ,再以 L aplace变换分析系统处理 ,了解血管壁硬度和血流情况。采用主要分析指标为 In order to compare maternal cerebral blood circulation with preeclampsia and normal pregnancy, the authors selected 26 preeclampsia, 11 cases of pregnancy-induced hypertension (PIH) and 17 normal pregnant women, all of whom were late pregnancy. Prior to the treatment of hypertension, the Doppler waveforms of the jugular, jugular and middle cerebral arteries were recorded and processed by the L aplace transformation analysis system to understand the vessel wall stiffness and blood flow. Using the main analysis indicators
