The evaluation of continuous fetal heart rate monitoring in high-risk pregnancy.
Intrapartum electronic fetal heart rate monitoring of the high-risk obstetric patient is thought to improve the perinatal outcome. A prospective randomized study of 483 high-risk obstetric patients in labor was carried out comparing the effectiveness of electronic fetal monitoring with auscultation of fetal heart tones. The infant outcome was measured by neonatal death, Apgar scores, cord blood gases, and neonatal nursery morbidity. There were no differences in the infant outcomes in any measured category between the electronically monitored group and the auscultated group. The cesarean section rate was markedly increased in the monitored group (16.5 vs. 6.8 per cent in the auscultated patients). The presumptive benefits of electronic fetal monitoring for improving fetal outcome were not found in this study.
