Abstract:
ob<x>jective To investigate the Foley catheter and low-dose of oxytocin induced by low cervical score in labor induction at term. Method W omen with a term , live, singleton fetus in cephalic presentation, Bishop score≤4, not in labor, medically indicated for labor induction from June 2017 to June 2019 in our hospital were randomly divided into observation group(n=90) and control group (n=90). In observation group, a 16-F Foley catheter was inserted into patient’s cervical canal and pass internal os, then the balloon was inflated with 80ml saline; at the same time intravenous low-dose oxytocin was initiated. In control group , patient only got intravenous low-dose oxytocin. 2or t test were used to compare the cervical ripening , delivery mode and outcome between the two groups. Result Observation group had a higher improvement of Bishop score, higher rate of vaginal delivery and shorter duration of labor than control group. There were no significant differences in neonatal birth weight and volume of postpartum hemorrhage between the two groups. Puerperal infection occurred in neither group. Conclusion The Foley catheter combined with low-dose of oxytocin i s simple and convenient, more effective for cervical ripening, with higher rate of vaginal delivery. It is recommended that Foley catheter combined with low-dose of oxytocin can be applied to labor induction in term pregnancy with low cervical score.
