Limitations of ST analysis in clinical practice: Cardiotocography only versus cardiotocography plus PR-interval analysis in intrapartum surveillance: Continuous electronic fetal monitoring has been shown to reduce the incidence of neonatal seizures, but there has been no beneficial effect in decreasing cerebral palsy or neonatal mortality. More in Pubmed Citation Related Articles. This requirement has probably created a significant source of confounding and bias since a number of different classification systems have been used to categorize the tracings in the published studies.
Consider need for expedited delivery operative vaginal delivery or cesarean delivery.
What We Have Learned About Intrapartum Fetal Monitoring Trials in the MFMU Network
The primary outcome measure was the incidence of metabolic acidosis, defined as an umbilical cord artery blood pH below 7. Computerized analysis of fetal heart rate variability using the matching pursuit technique as an indicator of fetal hypoxia during labor. When there is hypoxia, the energy balance within the myocytes becomes negative and the cells resort to beta-adrenoceptor—mediated anaerobic glycolysis. Reflects central nervous system activity: Table 1 Routes of and indications for delivery in the randomized trial of fetal pulse oximetry published by Garite and colleagues. The primary outcome was a reduction in cesarean deliveries for the indication of non-reassuring fetal status.
