【摘要】 目的探讨综合评分法预测妊娠晚期胎儿宫内状况的诊断价值。方法对577例孕妇产前进行多项指标联合监测,并综合评分。用受试者工作特征曲线(ROC曲线)分析综合评分法,选取最佳临界点(4分),计算敏感度、特异度、准确度、阳性预测值、阴性预测值,并与单项指标进行比较。结果综合评分法的敏感度(78．8％)、特异度(97．6％)、准确度(96．5％)、阳性预测值(66．7％)、阴性预测值(98．7％)均高于单项指标。结论综合评分法是预测胎儿宫内缺氧的有效方法。更多还原

【Abstract】 Objective To discuss the diagnostic value on prediction of the fetal intrauterine anoxia in late pregnancy by the method of all-round evaluation. Methods 577 cases were detected by multiphasic markers and all-round evaluation were proceeded. The evaluation results were analysed by ROC curve. The sensitivity, specificity, accuracy, positive predictive value, negative predictive value were calculated and compared with that of single marker. Results ROC curve analysis showed sensitivity, specificity, accuracy, positive predictive valu-e, negative predictive value of all-round evaluation were higher than that of single marker. Conclusion The method of all-round evaluation is the effectual method to diagnose the fetal intrauterine anoxia.更多还原
