1990～91年,在宁夏的两个县农村中,按前瞻性现场配对调查方法分住院分娩和家庭分娩二组,对引起产后失血高危因素进行筛选,分析了各因素的相对危险度,应用产后失血评分法预测得每个评分的产后失血发生率,还通过精确测量产后2h内的失血量,证实了本评分分法的科学性和可靠性。作者等提出,农村住院分娩的切点以“3”分为宜,该评分法能较好地预测产后失血,具有实用性,便于推广。
From 1990 to 1991, in the two counties of Ningxia, the two groups were divided into hospital delivery and family delivery according to the prospective field match-up survey method. The risk factors of postpartum hemorrhage were screened, the relative risk of each factor was analyzed, The hemorrhage scoring method predicts the postpartum hemorrhage rate of each score, and also confirms the scientificalness and reliability of the scoring system by accurately measuring the amount of blood loss within 2 hours after delivery. The author put forward that rural hospital delivery point of cut to “3” is appropriate, the score method can better predict postpartum hemorrhage, practical, easy to promote.
