本文对205例高危孕产妇,240次胎心率(FHR)试验结果进行了回顾性分析。监护试验结果正常(NST反应型或OCT/CST阴性)预测胎婴儿情况良好的准确性高达90％以上;试验结果异常(NST无反应型或OCT/CST阳性)预测胎儿预后不良的准确性分别为27％和12.5％,有较高的假阳性率。因此胎心率监护试验必须结合临床情况和其它检验,才能对胎儿情况作出准确判断。在有围产并发症的孕产妇中,40～70％表现有FHR图形异常,说明某些围产并发症与异常FHR图形间有相关关系。文内还讨论了异常FHR图形的临床意义。
The 205 cases of high-risk pregnant women, 240 fetal heart rate (FHR) test results were retrospectively analyzed. The accuracy of the monitoring test results was normal (NST response or OCT / CST negative) predictive accuracy of up to 90% of fetuses; accuracy of abnormal test results (NST non-responsive or OCT / CST positive) to predict poor fetal prognosis were 27% and 12.5%, a higher false positive rate. Therefore, fetal heart rate monitoring test must be combined with clinical conditions and other tests in order to make accurate judgments on the fetus. In pregnant women with perinatal complications, 40 to 70% of the performance of FHR pattern abnormalities, indicating that some perinatal complications and abnormal FHR patterns have a correlation between. The article also discussed the clinical significance of abnormal FHR graphics.
