摘　　要：目的 :探讨胎心监护对颅测胎儿宫内窘迫的价值。方法 :应用胎心监护仪对 2 0 4例临产前和 (或 )临产后的孕妇进行胎心监护。结果 :NST(无负荷试验 )有反应型 (12 5例 )发生胎儿窘迫 2 .4 % ,NST无反应型 (19例 )发生胎儿窘迫 4 7.37% ,P〈0 .0 1,有显著的差异 (宫缩刺激试验 )阴性 (5 2例 )胎儿窘迫发生 11.5 4% ,CST阳性 (8例 )发生胎儿窘迫 87.5 0 % ,p〈0 .0 1,有明显的差异。结论 :NST和CST分别是产前和产时胎心监护的有效方法 ,可以作为预测胎儿宫内窘迫的筛选试验 ,其准确性、敏感性、阴性预测值、阳性预测值分别为 90 .97%、75 %、97.6 %、4 7.37和 88.33%、5 3.85 %、88.4 6 %、87.5 0 %。Objective: The aim of our study was to evaluate the result of fetal monitoring in predicting fetal distress.Method: Fetal monitoring was examined in 204 cases pregnant women in antepartum and (or) intrapartum by cardiotocography instrument.Result: Fetal distress rate was 2.4% in 125 cases of NST (non-stress test) reactive type, it was 47.37% in 19 cases of NST nonreactive type, P<0.01, there were very obvious differences between two groups. Fetal distress rate was 11.54% in 52 cases of CST(Contraction stresstest) positive, it was 87.50% in 8 cases of CSTspecificity,P<0.01,there were obvious differences between two groups.Conclusion:NST and CST are effective method that they are performed in antepartum and intrapartum fetal monitoring reapectively, the technique of csrdiotocography can be used as a screen test to predict the fetal distress ,the accuraey, sensitivity, positive predictive value, negative predictive value were 90.97%, 75%,97.6,47.37% and 88.33%,53.85%,88.46%,87.50% respectively.
