基于模糊理论的产后大出血风险预测

The Risk Forecast of Postpartum Hemorrhage Based on Fuzzy Theory

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.

In this paper, the risk of postpartum hemorrhage was predicted by fuzzy comprehensive evaluation. According to a large number original medical data of postpartum hemorrhage, a suitable evaluation index system was established, the membership function Was constructed with postpartum hemorrhage, and the weight set was determined, the singlefactor evaluation matrix was constructed. On the basis of the clinical features of postpartum hemorrhage, we have designed a dynamic evaluation system and predicted the level of risk of postpartum hemorrhage and found the possibility of starting of postpartum hemorrhage. Based on a large amount of case test shows that, the results are consistent with the clinical diagnosis, which verifies the correctness of the theory and practicality of this article.
