NST反复异常的妊娠结局初探

目的探讨NST反复异常的临床价值.方法1996年2月至1999年1月在本院住院分娩且产前NST异常2次以上的孕妇204例为异常组和随机抽出同期NST正常孕妇103例为对照组.所有孕妇在行NST的同时都进行声振动声刺激试验,并对两组孕妇的妊娠结局进行比较.结果异常组中有妊娠合并症和发生围产儿预后不良者明显高于对照组(P＜0.05,P＜0.01,P＜0.005);在异常组中,距最后一次检查于3天内分娩的孕妇发生围产儿预后不良明显低于3天后分娩的孕妇(P＜0.05).结论NST反复异常提示胎儿在宫内有不同程度的缺氧.

Pregnancy Outcome in the Patient with Abnormal Nonstress Test Repeatedly

Objectives:To study the clinical value of abnormal nonstress test(NST)repeatedly.Methods:204 patients with more than twice of abnormal NSTas abnormal group and 103 cases with reactive NST as control group,delivered their babies ed in our hospital from Feb.1996 to Jun.1999.All cases had undergone Vibtratory Acoustic Stimulation Test (VAS T)when underdoing NST.We study the pregnancy outcome of two groups.Results:The rate of pregnancy with complication and poor perinatal prognosis in abnormal group is high than that in the control group( P <0.05,<0.01,<0.005).Conclusions:Indiated intrauterine fetal distress was implied by nonstress test is abnormal repeatedly .In these cases,the rate of poor perinatal prognosis is usually higher than that in the cases of reactive nonstress test
