Bladder drainage during labor: A randomized controlled trialjog

Aim: To compare two bladder draining methods during labor on time to delivery, cost and nursing preference. Material and Methods: This trial randomized 139 women with singleton pregnancies in active labor or undergoing induction of labor. Eligibility required an anticipated vaginal delivery with a clinical indication for bladder catheterization (epidural). Participants were randomly assigned to either indwelling or intermittent catheterization. The primary outcome was time to delivery; secondary outcomes were nurse preference, cost and route of delivery. A sample size of 138 women would be needed for 80% power to detect a 30 min difference in the time to delivery interval with a 0.05 alpha error. Results: Outcome data was available for 138 patients (72 indwelling and 66 intermittent). The time to delivery was similar among the two groups (13.8 h for indwelling and 14.4 h for intermittent). Route of delivery and cost estimate was similar in both groups; however, nurses preferred the indwelling method. Conclusion: Indwelling catheterization is recommended as the standard method for bladder drainage in laboring women with epidural.
