Pudendal Enhancement of Enhanced Recovery After Surgery (ERAS) for Reconstructive Surgery (PEERS)

PROTOCOL SUMMARY AND/OR SCHEMA

To determine whether administration of a PNB at time of vaginal reconstructive surgery can reduce use of narcotics and reported pain scores in the immediate postoperative period within the setting of multimodal postoperative pain control of ERAS. Women >18yo undergoing vaginal reconstructive surgery without a hysterectomy will be randomized to either standard of care with typical use of local anesthetic during their surgery versus perioperative PNB in addition to typical use of local anesthetic during their surgery. PNB will be performed with 0.5% bupivacaine and 10cc will be injected bilaterally. All patients will be on a standard preoperative and postoperative multimodal pain regimen. Patients will be followed until 6 weeks after surgery.

OVERVIEW OF STUDY DESIGN/INTERVENTION

This will be a prospective blinded randomized controlled trial. We will recruit women who are undergoing vaginal prolapse repair surgery with a Female Pelvic Medicine and Reconstructive Surgery fellowship-trained provider within the UCLA Health System. Women will be recruited prior to undergoing vaginal reconstructive surgery. They will then be randomized to control group with standard of care with local anesthesia used during surgery (Group 1) or PNB in addition to use of local anesthesia typically used during surgery (Group 2).

All pain medication will be standardized. Preoperative medications per our ERAS protocol will include oral acetaminophen 1000mg, gabapentin 600mg, and celecoxib 400mg. During surgery the patient will undergo their randomized intervention as either Group 1 or Group 2. Postoperative medications per our ERAS protocol including scheduled acetaminophen 1,000mg PO every 6 hours and ketorolac 30mg IV every 6 hours. For supplemental pain medication patients will have the following available: tramadol 50mg PO every 6 hours as needed for moderate pain (pain 4-6/10 on NRS scale), tramadol 100mg PO every 6 hours as needed for severe pain (pain 7-10/10 on NRS scale), and oxycodone 5mg PO every 4 hours as needed for breakthrough pain as supplemental pain medication. If the above regimen does not allow for sufficient pain control then additional hydromorphone IV 0.2mg or morphine IV 2mg can be ordered by the provider as needed, but will not be standard in the postoperative order set. The providers will know what intervention the patients underwent, but the patients and the care team obtaining pain scores in the hospital will be blinded to the intervention.
