Background: Epidural analgesia provides the most effective pain relief in labor, but it is not known if it causes adverse long‐term effects. The objective of this study was to assess the long‐term effects of two mobile epidural techniques relative to high‐dose epidural analgesia in a randomized controlled trial. Methods: A total of 1,054 nulliparous women were randomized to traditional high‐dose epidural, combined spinal epidural, or low‐dose infusion. Women in all groups were followed‐up at 12 months postpartum by postal questionnaire to assess long‐term symptoms. The primary long‐term outcome was backache occurring within 3 months of the birth persisting for longer than 6 weeks. Secondary outcomes were frequent headaches and fecal and urinary stress incontinence. Results: No significant differences were found in long‐term backache after combined spinal epidural or low‐dose infusion relative to high‐dose epidural. Significantly less headache occurred in combined spinal epidural analgesia than high‐dose epidural (OR: 0.57, 95% CI: 0.36–0.92), but no difference was found for low‐dose infusion. Significantly less fecal incontinence (OR: 0.51, 95% CI: 0.30–0.87) and stress incontinence (OR: 0.65, 95% CI: 0.42–1.00) occurred with low‐dose infusion. Conclusion: Trial evidence showed no long‐term disadvantages and possible benefits of low‐dose mobile relative to high‐dose epidural analgesia. (BIRTH 38:2 June 2011)
