Two randomized controlled trials (RCT) on intrapartum fetal monitoring with cardiotocography (CTG) only versus CTG combined with automatic ST segment waveform analysis of the fetal ECG have been performed. In altogether 6826 randomized cases, the odds ratio for operative delivery for fetal distress (ODFD) was 0.65 (95% confidence interval 0.53-0.78) and for metabolic acidosis at birth 0.39 (0.21-0.72), in favor of the CTG+ST method. CTG combined with ST analysis increases the ability of obstetricians to identify fetal hypoxia and to intervene more appropriately, resulting in an improved perinatal outcome.
已经进行了两项关于产时胎儿监测的随机对照试验（RCT），一项仅使用胎心宫缩图（CTG），另一项将CTG与胎儿心电图的自动ST段波形分析相结合。在总共6826例随机病例中，胎儿窘迫剖宫产（ODFD）的比值比为0.65（95%置信区间0.53 - 0.78），出生时代谢性酸中毒的比值比为0.39（0.21 - 0.72），支持CTG + ST方法。CTG与ST分析相结合提高了产科医生识别胎儿缺氧并更恰当地进行干预的能力，从而改善了围产期结局。
