Cervical condition and fetal cerebral Doppler as determinants of adverse perinatal outcome after labor induction for late‐onset small‐for‐gestational‐age fetuses. (4th November 2015) - Garcia‐Simon, R.
Abstract : Linked Comment: Ultrasound Obstet Gynecol 2015; 46: 649–649 ABSTRACT: Objective: To estimate the combined value of fetal cerebral Doppler examination and Bishop score for predicting perinatal outcome after labor induction for small‐for‐gestational‐age (SGA) fetuses in the presence of normal umbilical artery Doppler recordings. Methods: We conducted a cohort study in two tertiary centers, including 164 women with normal umbilical artery Doppler recordings who underwent induction of labor because of an estimated fetal weight < 10 th percentile. The fetal middle cerebral artery pulsatility index and cerebroplacental ratio (CPR) were obtained in all cases within 24 h before induction. Cervical condition was assessed at admission using the Bishop score. A predictive model for perinatal outcomes was constructed using a decision‐tree analysis algorithm. Results: Both a very unfavorable cervix, defined as a Bishop score < 2, (odds ratio (OR), 3.18; 95% CI, 1.28–7.86) and an abnormal CPR (OR, 2.54; 95% CI, 1.18–5.61) were associated with an increased likelihood of emergency Cesarean section for fetal distress, but only the latter was significantly associated with the need for neonatal admission (OR, 2.43; 95% CI, 1.28–4.59). In the decision‐tree analysis, both criteria significantly predicted the likelihood of Cesarean section for fetal distress. Conclusion: Combined use of the Bishop score and CPR improves the ability to predict overall Cesarean section (for any indication), emergency Cesarean section for fetal distress, and neonatal admission after labor induction for late‐onset SGA in the presence of normal umbilical artery Doppler recordings.
