RCT (Randomized Controlled Trial) of IV Acetaminophen for Post Operative Vaginal Reconstruction Pain

July 19, 2018 updated by: TriHealth Inc.

The Effect of Intravenous Acetaminophen on Post-operative Pain and Narcotic Consumption in Vaginal Reconstructive Surgery Patients: A Randomized Controlled Trial

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.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Pain While Active - 18 hr
Time Frame: 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.
18 hours
Total Amount of Narcotic Consumption in the First 24 Hours Post Surgery
Time Frame: 24 hours
Hydromorphone will be administered for breakthrough pain. The total amount consumed in the first 24 hours post surgery will be recorded.
