Abstract

Objective: To compare pre and post Foley's catheter Bishop Score during labour induction.

Methods: This study was a retrospective study conducted at the Aga Khan University Hospital Karachi, Pakistan after approval from ethical review board. All women who underwent induction of labour with Foley's Catheter at gestation of 37 weeks or more from September 2014-October 2015 were included. Data was entered and analyzed in Statistical Package for Social Sciences (SPSS) version 19.0. The comparison between pre and post Foley's catheter Bishop Score during labour induction will be calculated by Wilcoxon sign test.

Results: There were 981 cases of inductions of labour, 749 (76.3%) received Foley's catheter, in combination with prostaglandins and oxytocin. About 68% were vaginal deliveries while 32% underwent C-section. Two third of women had bishop <4. Overall, Bishop score improved significantly in all patients with the catheter however, maximum benefit was seen in patients where the catheter was placed for 10-12 hours.

Conclusion: Foley's is the better and safer option. In view of our results, It has been recommended to keep the Foley's for 10-12 hours to get significant improvement in bishop score.
