RCT of IV Acetaminophen for Post Operative Vaginal Reconstruction Pain
This randomized controlled trial will evaluate the effects of perioperative intravenous (IV) acetaminophen on postoperative narcotic consumption and pain scores in subjects undergoing vaginal reconstructive surgery. One hundred subjects will be randomly assigned to receive either IV acetaminophen or IV placebo. Those in the IV acetaminophen group will receive 1000mg IV every 6 hours for 24 hours beginning prior to anesthesia induction. The control group will receive placebo saline infusions at the same time intervals. All subjects will receive as needed (prn) IV narcotic for additional pain relief. Visual analog scales (VAS) regarding pain will be evaluated at 18 and 24 hours postoperative and immediately prior to discharge. We will also collect total IV narcotic consumption. We hypothesize that subjects receiving IV acetaminophen will have lower VAS scores and decreased total narcotic consumption in comparison to the control group.

|Official Title:||The Effect of Intravenous Acetaminophen on Post-operative Pain and Narcotic Consumption in Vaginal Reconstructive Surgery Patients: A Randomized Controlled Trial|
- Post Operative Pain [ Time Frame: 24 hours ] [ Designated as safety issue: No ]Post operative pain will be assessed 18 and 24 hours after surgery and immediately prior to discharge. Pain will be self reported by patients using a 10cm visual analog scale (VAS). At each time point a pain score will be collected for pain at rest and pain with ambulation or an action symbolizing ambulation (i.e. coughing).
- Total amount of narcotic consumption in the first 24 hours post surgery [ Time Frame: 24 hours ] [ Designated as safety issue: No ]Hydromorphone will be administered for breakthrough pain. The total amount consumed in the first 24 hours post surgery will be recorded.
- Narcotic associated side effects [ Time Frame: 24 hours ] [ Designated as safety issue: No ]The incidence of known narcotic associated side effects will be recorded, including: nausea, emesis, itching, headache, insomnia, rash/hives, shortness of breath, respiratory depression, and urinary retention.
- Time to first rescue narcotic [ Time Frame: 24 hours ] [ Designated as safety issue: No ]The time from the end of surgery to the time any IV narcotic is given.
- Time to ambulation [ Time Frame: 24 hours ] [ Designated as safety issue: No ]Length of time from the end of surgery to the time of ambulation.
- Time to first flatus/bowel movement [ Time Frame: 24 hours ] [ Designated as safety issue: No ]Length of time from the end of surgery to the time of first flatus or bowel movement.
