先兆子痫有时出现DIC综合征的血凝异常。凝血异常与先兆子痫发病有重要联系,已肯定凝血改变的严重程度与先兆子痫呈正相关。为对高凝开始时间、特征和发生先兆子痫的机制进行研究,选择50例22～32岁处于发生先兆子痫危险的孕妇列为研究对象。先兆子痫包括每周体重增加,血压不稳定,尿量减少和夜尿。症状在孕24周,30周前出现者分别为56％和44％。因此止血法调研时间定在6 Preeclampsia Sometimes there is abnormal coagulation in DIC syndrome. Coagulation abnormalities are associated with the development of preeclampsia, and the severity of changes in coagulation is positively correlated with preeclampsia. To study the timing of hypercoagulable onset, characteristics and mechanisms of preeclampsia, 50 pregnant women aged 22-32 years who were at risk for developing preeclampsia were enrolled in this study. Pre-eclampsia includes weekly weight gain, unstable blood pressure, decreased urine output and nocturia. Symptoms at 24 weeks pregnant, appeared 30 weeks ago were 56% and 44%. Therefore, hemostasis research time set at 6
