Abstract :Purpose: This study aims to investigate the effect of cervical length measured before induction of labor on the duration of labor and oxytocin dose administered for induction during labor in post-term pregnant women. Materials and Methods: Eighty-seven post-term pregnant women were included in this prospective study. Cervical length was measured before the induction of labor with oxytocin. The relationship between cervical length and the time until delivery and total oxytocin dose parameters were examined. The effect of confounder factors was determined by logistic regression analysis. Results: Sixty-five insert ignore into journalissuearticles values(74.71%); of the patients gave birth by normal vaginal delivery and 22 insert ignore into journalissuearticles values(25.29%); by cesarean section. It was found that parity, bishop score, cervical length and fetal weight variables predicted oxytocin dose by 67% insert ignore into journalissuearticles values(R-square = 0.675);. Patients with a cervical length of >32mm measured before induction were more likely to have a cesarean section than those with a cervix shorter than 32 mm insert ignore into journalissuearticles values(OR:3.7);. Parity had the greatest effect among these variables insert ignore into journalissuearticles values(β = -.40, p <.001);. Conclusion: Cervical length is a useful marker in predicting the success of labor induction with oxytocin in post-term pregnant women. The total oxytocin dose used in labor induction is related to cervical length.
