title: The transcervical foley catheter versus the vaginal prostaglandin e2 gel in the induction of labour in a previous one caesarean section - a clinical study.
abstract: OBJECTIVE
  To compare the effectiveness and the safety of the transcervical Foley catheter and the prostaglandin E2 (PGE2) gel for the induction of labour in women with a previous one caesarean section with an unfavourable cervix at term.
  
  
  METHODS
  This study was conducted in the Department of Obstetrics and Gynaecology, J.N. Medical College, Aligarh, (U.P),India. Seventy women with singleton pregnancies at term, with previous one lower segment caesarean sections with a cephalic presentation and a Bishop's score of ≤ 6, who required induction at term were included in the study. Group A had 35 women in whom the transcervical Foley catheter was inserted and Group B included 35 women in whom the PGE2 gel was inserted vaginally for the induction of labour.The Bishop's score after 12 hours of induction, the oxytocin requirement, the induction to delivery interval, the mode of delivery, the maternal complications and the neonatal outcome were compared.
  
  
  RESULTS
  The Foley catheter and the PGE2 gel had a comparable effect on the Bishop's score after 12 hours and the induction to the delivery interval was slightly shorter with the Foley catheter (18.15 hours) as compared to 21.06 hours with the PGE2 gel. There was no case of uterine rupture or scar dehiscence.
  
  
  CONCLUSIONS
  In this study, both the modes of induction in women with previous one caesarean sections were safe, simple and effective. The main advantages of the cervical ripening with the Foley catheter over the Prostaglandin E2 gel are the low cost, reversibility and the lower risk of systemic and serious side effects like uterine hyperstimulation and rupture, as well as it induces a significant ripening and dilatation of the cervix and a shorter induction to the delivery interval. So, the cervical ripening effect of the Foley catheter is as good as that of the Prostaglandin E2 gel in women with previous one caesarean sections.
