妊娠高血压综合征是最常见的病理妊娠,是围产期母婴死亡及并发症的重要原因。其预后与病情严重程度有关,如加强孕期保健,尽早预防必能降低围产期母婴死亡率及并发症。本文目的是通过孕中期平均动脉压(MAP)的测量,以预测妊高征的 Pregnancy-induced hypertension is the most common pathological pregnancy, which is an important cause of perinatal maternal and infant deaths and complications. The prognosis and the severity of the disease, such as strengthening the health care during pregnancy, early prevention will be able to reduce perinatal maternal and infant mortality and complications. The purpose of this paper is to measure pregnancy-induced hypertension by measuring the second trimester mean arterial pressure (MAP)
