Abstract: 【Abstract】  Early recognition of the pregnant women with preeclampsia can reduce the risk of maternal and fetal morbidity and mortality. Uterine artery doppler waveform analysis for prediction of second trimester pregnancy preeclampsia markers have been widely studied. And the use of uterine artery doppler in first trimester pregnancy to predict preeclampsia become a research hotspot in recent years. Uterine artery doppler parameters as individual markers, its sensitivity is not high. First-trimester uterine artery doppler parameters (such as pulse index) combined with the maternal characteristics and biochemical markers (such as: pregnancy associated plasma protein A and placental growth factor) can achieve more than 90% rates of detection of early-onset preeclampsia. But in combination with biochemical markers increased costs, the future research direction is early screening of optimal combination forecasting model to predict preeclampsia.
