Epidural Hydromorphone for Postpartum Pain Management After Vaginal Delivery: A Randomized Clinical Trial

ABSTRACTBackground Mothers frequently experience differing intensities of postpartum analgesia following vaginal delivery; however, there remains a deficiency of effective and readily available modalities for postpartum pain management. This study aims to assess the analgesic efficacy and safety profile of epidural hydromorphone in the treatment of postpartum pain.Methods This randomized controlled trial enrolled 460 full-term women who had a full-term vaginal delivery. The participants received either epidural hydromorphone (HY group) or normal saline (NS group). The primary outcome was pain scores within 48 hours postpartum, with the occurrence of adverse events systematically documented.Results Within 48 hours post-treatment, median pain scores were significantly lower in HY group compared to NS group (P Conclusions Epidural hydromorphone effectively reduced postpartum pain, with manageable side effects. Clinicians should balance the benefits and potential risks when considering postpartum analgesia.Key PointsQuestionIn women post-vaginal delivery, does the administration of epidural hydromorphone offer superior analgesia and enhance maternal satisfaction relative to a placebo (normal saline)?FindingsEpidural hydromorphone demonstrated a statistically significant reduction in postpartum pain scores, a decreased requirement for supplemental analgesics, and enhanced maternal satisfaction. Observed adverse effects included nausea, dizziness, pruritus, and urinary retention, all of which were deemed manageable.MeaningEpidural hydromorphone presents as a viable analgesic modality for the management of postpartum pain following vaginal delivery, offering effective pain relief within an acceptable safety profile.
