应用胎心电子监护、非应激试验(NST)或宫缩应激试验/催产素激惹试验(CST/OCT)是高危妊娠产前监护的主要手段。已确知,阳性 CST/OCT 可预告围产期死亡率危险的增加,但在使用上由于推断的困难和潜在的危险而受限制。由于NST 易行迅速无损害,很快被推广做为产前监护的手段。然而,有关其敏感性(检出所有真正异常的能力)和特异性(避免假阳性)的问题已被提出。本研究怀疑 NST-CST/OCT 对高危妊娠是否 Application of Fetal Heart Rate Monitoring, NST or CST / OCT is the primary means of prenatal care for high-risk pregnancies. It has been established that positive CST / OCT predicts an increase in the risk of perinatal mortality but is limited in its use due to inferred difficulties and potential risks. Because NST is rapidly and easily accessible, it is rapidly being promoted as a means of prenatal care. However, questions about their sensitivity (ability to detect all true abnormalities) and specificity (to avoid false positives) have been proposed. This study questioned whether NST-CST / OCT was associated with high-risk pregnancies
