RCT (Randomized Controlled Trial) of IV Acetaminophen for Post Operative Vaginal Reconstruction Pain
- Registration Number
- NCT02043704
- Lead Sponsor
- TriHealth Inc.
- Brief Summary
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.

Group Intervention Description IV Acetaminophen IV Acetaminophen Subjects will receive a 1000mg dose of IV acetaminophen in 100mL solution every 6 hours for 24 hours. The first dose will be administered prior to anesthesia induction, approximately 30 minutes before skin incision. A total of 4 doses will be given. Saline IV Acetaminophen Subjects will receive a 100mL dose of IV saline every 6 hours for 24 hours. The first dose will be administered prior to anesthesia induction, approximately 30 minutes before skin incision. A total of 4 doses will be given.
- Primary Outcome Measures
Name Time Method Total Amount of Narcotic Consumption in the First 24 Hours Post Surgery 24 hours Hydromorphone will be administered for breakthrough pain. The total amount consumed in the first 24 hours post surgery will be recorded.
Pain While Active - 18 hr 18 hours Post operative pain will be assessed 18 hours after surgery. Pain will be self reported by patients using a 0-100 mm visual analog scale (VAS) with 0 indicating no pain and 100 indicating the worst pain imaginable. A pain score will be collected for pain while active.
- Secondary Outcome Measures
Name Time Method Narcotic Associated Side Effects 24 hours The incidence of known narcotic associated side effects will be recorded for urinary retention.
Time to First Rescue Narcotic 24 hours The time from the end of surgery to the time any IV narcotic is given.
Time to Ambulation 1800 minutes Length of time from the end of surgery to the time of ambulation.
