Antepartum Cardiotocography With and Without Computer Analysis in High Risk Pregnancies
Antepartum Cardiotocography With and Without Computer Analysis in High Risk Pregnancies
Electronic fetal hear rate monitoring (EFM), or cardiotocography (CTG), records changes in
 fetal heart rate and their temporal relationship to uterine contraction. It has been
 developed with the aim of detecting fetal hypoxia during labor and hence to prevent metabolic
 acidosis. Despite being the standard for intrapartum management, this technique,
 significantly increase the operative delivery rate, and is associated only with less seizures
 as neonatal benefit. Another concern is also the variability in the interpretation.

 Several techniques have been studied in order to decrease the high false positive rate. Fetal
 ST waveform analysis (STAN) has been studied combined with CTG. A recent meta-analysis of
 randomized trials, however, showed that STAN during labor did not improve perinatal outcomes
 or decrease operative delivery rates, except for a 9% decrease in operative vaginal
 delivery.Comparisons of visual and computerized interpretation of EFM have also been
 reported. However, whether or fetal monitoring with computer analysis improve perinatal
 outcomes is still subject of debate.

 Thus, we aim to evaluate whether intrapartum fetal monitoring with computer analysis increase
 the incidence of obstetric intervention when compared with visual analysis through a
 single-center randomized controlled trial.
