Pediatric follow-up of a randomized controlled trial of intrapartum fetal monitoring techniques.
A controlled prospective study was conducted to evaluate possible effects of the use of three intrapartum fetal monitoring techniques on the offspring of high-risk mothers in labor after at least 34 weeks' gestation. Six hundred and ninety women were randomly assigned to one of the three monitoring groups: auscultation alone, electronic monitoring alone, and electronic monitoring with option to obtain fetal scalp pH. There were no significant differences among the three groups of offspring with respect to neonatal mortality or morbidity, Apgar scores, cord blood gas values, or Brazelton examinations at ages 2 to 3 days. Assessment of the infants at 9 months revealed no significant differences in their growth and development as assessed by physical examination. Bayley Scales of Infant Development, and Milani-Comparetti tests. The frequency of delivery by cesarean section was significantly higher in the electronically monitored group than in the auscultated group. This study failed to show beneficial effects of electronic fetal monitoring over auscultated monitoring for high-risk but relatively mature fetuses.
