Cesarean Section At Full Cervical Dilatation: When Is It Troubling For Newborn?

Aim: We aimed to investigate the potential risk factors related to poor perinatal outcomes after cesarean section performing at full cervical dilatation. Material and Method: Fourty-nine women who underwent cesarean section at full cervical dilatation were enrolled in this retrospective case-control study. Women with poor perinatal outcome defined as the presence of admission to neonatal intensive care unit were the cases while the women without poor perinatal outcome were controls. Two groups were analyzed to determine possible risk factors for poor perinatal outcome with multivariate logistic regeression model. ROC curve analysis was used to find cut off point of duration of arrest at full cervical dilatation for poor perinatal outcomes with significant factors. Results: Of 49 women, 9 (18.4%) women constructed the case group while 40 (81.6%) women were in control group. In multivariate analysis persistent occiput posterior position was the only factor to be significant for the poor perinatal outcome after cesarean section at full cervical dilatation. The best cut-off point of duration of arrest at full cervical dilatation for poor perinatal outcome with persistent occiput posterior position established by the ROC curve was 1.25 hour, showing a sensitivity of 75.0 %, specificity of 50.0 %. Discussion: Persistent occiput posterior position may be a risk factor for adverse perinatal outcomes of cesarean section at full cervical dilatation. All obstetricians should be aware of duration of arrest at full cervical dilatation with persistent occiput posterior position and this interval should not be longer than 1 hour
