Efficacy of IV Acetaminophen Versus Oral Acetaminophen

Phase 4
Completed
Conditions
Nephrectomy
Interventions
Drug: Placebos
Drug: Placebo Oral Tablet
Registration Number
NCT03365622
Lead Sponsor
University of Rochester
Brief Summary

The aim of this study is to determine whether intravenous acetaminophen compared to enteric acetaminophen offers increased efficacy in patients who are scheduled for laparoscopic donor nephrectomy and for patients scheduled for robot-assisted, laparoscopic nephrectomy for cancer at the University of Rochester Medical Center. The standard surgical and post-operative care, including post-operative pain management will not be altered.

Primary Outcome Measures
NameTimeMethod
Total Opioid Dose (MME) Used in 24 Hours20 to 24 hours post-operatively

Total opiate dose used from the study start (when the first dose of acetaminophen is administered in the pre-anesthesia holding area) to 24 hours post-operatively (in morphine milligram equivalents (MME)).This will include opiates administered intra-operatively.

Secondary Outcome Measures
NameTimeMethod
Average Surgical Pain Intensity1-2 hours post-operatively

Average surgical pain intensity on a 0-10 numeric rating scale (NRS) administered between 20 and 24 hours post-operatively, with gatekeeping used to control for multiplicity. A larger NRS score means the patient is experiencing more pain, with 0 representing "no pain" and 10 representing "the worst possible pain".

Mean Inspiratory Capacity20-24 hours post-operatively

The mean inspiratory capacity is presented as a percentage of the subject's baseline (pre-operative) inspiratory capacity, recorded at the time of pain intensity assessments between 20-24 hours postoperatively. Inspiratory capacity is measured using a Voldyne 5000 incentive spirometer (Hudson RCI, Teleflex Medical) and recorded in milliliters to the nearest 250 cc mark on the incentive spirometer. Higher percentages reflect better recovery of inspiratory function.

Dynamic Pain Score During Incentive Spirometer Use20-24 hours post-operatively

Dynamic pain score on a 0-10 numeric rating scale (NRS) with incentive spirometer use taken during pain intensity assessments at 20-24 hours post-operatively. A larger NRS score means the patient is experiencing more pain, with 0 representing "no pain" and 10 representing "the worst possible pain".

Surgical Pain Score During the 20-24 Hour Assessment20-24 hours post-operatively

Pain intensity on a 0-10 numeric rating scale (NRS) prior to incentive spirometry use was taken during pain intensity assessments at 20-24 hours post-operatively. A larger NRS score means the patient is experiencing more pain, with 0 representing "no pain" and 10 representing "the worst possible pain".

Time to First Narcotic Use24 hours post-operatively

Time to first postoperative narcotic use, measured in hours (range: 1 to 24).

Number of Participants With Nausea24 hours post-operatively

Number of participants with nausea was assessed based on the administration of anti-emetic medications, with a value of 0 indicating no nausea and 1 indicating the presence of nausea.

Time to Discharge From Post-anesthesia Care Unit24 hours

Length of time in minutes from PACU(post-anesthesia care unit) arrival to discharge.

Time to Hospital Discharge30 days

Number of days to discharge from hospital
