An observational study in Term Pregnancy, Doppler Parameters and Induction of Labor, sponsored by Istanbul Medeniyet University. Completed at 1 site in Turkey. Open to female participants aged 18 Years to 40 Years, including healthy volunteers. Per ClinicalTrials.gov, last updated 2019-11-13.
Sponsored by Istanbul Medeniyet University · Observational
Term pregnancies within their 37-41 gestational week, who were planned to undergo induction of labor, were included in the study. Prior to initiation of the induction of labor, all included pregnant women underwent an assessment of Doppler flow indices, which included fetal umblical artery PI (pulsatility index) and fetal middle cerebral artery (MCA:Middle cerebral arter) PI. Cerebroplacental Ratio (CPR) was calculated by dividing MCA PI value to umbilical artery PI (MCA PI/UA PI=CPR).Included pregnant women were categorized as Group 1 and Group 2, which comprised of those with CPR value below 1.0 and above 1.0, respectively. Route of delivery and fetal complications, described as umbilical cord pH\<7.20, APGAR score at 5 minutes \<7, meconium aspiration syndrome, newborn intensive care unit admission, neonatal sepsis and neonatal death.

All women who were considered appropriate for induction of labor were performed an pelvic examination and their Bishop scores were calculated. Those with a Bishop score equal to or below 5 were included in the study. Vaginal misoprostol (prostoglandin E1, 25 mcg) and dinoproston (prostoglandin E2, 10 mg) were used for induction of labor. Repeat doses were implemented in case of insufficient cervical ripening. Oxytocin was not used at the initial stages of labour, while it was used at the latter stages when necessary.
Route of delivery and fetal complications, described as umbilical cord pH\<7.20, APGAR score at 5 minutes \<7, meconium aspiration syndrome, newborn intensive care unit admission, neonatal sepsis and neonatal death.
