Research of the relation between D/W ration of umbilical cord around the neck and fetal intrauterine anoxia by ultrasonography detection

目的应用多普勒超声检测胎儿绕颈脐带切面的深度(D)与宽度(W),评价D/W与胎儿宫内缺氧的关系.方法选择孕周36～42周脐带绕颈胎儿342例,测量D/W值,检测脐动脉血流参数及胎心率,行无应激试验胎儿监护,产后追踪羊水及胎儿Apgar评分.结果缺氧组D/W为(0.39±0.08),非缺氧组D/W为(0.55±0.09),两者比较差异有显著意义;两组脐动脉血流动力学参数、胎心率异常、羊水混浊及胎儿Apgar评分＜7的例数比较,差异均有显著意义(P＜0.01).结论超声检测绕颈脐带切面D/W比值可及时提示胎儿宫内缺氧,为临床尽早诊断和治疗提供有力帮助.02299-3001
