运用模糊综合评判的方法对孕产妇产后大出血的风险进行预测评估.依据大量产后出血的医学资料,建立了合适的评价指标体系,利用改进的层次分析法确定权重集,构造出隶属函数,得到单因素评判矩阵.依据产后大出血的临床医学特点,设计了一个动态的评判系统,根据每个病人的个体情况进行综合评判,预测出发生产后出血的风险等级,并给出引起出血的可能原因.通过对大量病例测试表明,该系统评判结果与临床诊断相一致,从而验证了理论的正确性和实用性.
Applying the method of fuzzy comprehensive evaluation to forecast the risk of maternal postpartum hemorrhage.According to the massive medical data of postpartum hemorrhage, set up a suitable evaluation index system, use the improved analytic hierarchy process to determine the weight set, construct the membership function and get the single Factor evaluation matrix.According to the clinical features of postpartum hemorrhage, a dynamic evaluation system was designed to evaluate the risk level of postpartum hemorrhage according to the individual condition of each patient, and the possible causes of hemorrhage were given.Through Tests on a large number of cases show that the results of the system are consistent with clinical diagnosis, which verifies the correctness and practicability of the theory.
