Total Knee Arthroplasty Clinical Trial
Official title:
A Randomized, Double-Blinded, Placebo-Controlled Trial Comparing a Multi-Modal Pain Protocol With and Without Opioids Following Total Joint Arthroplasty
To help curb the use of opioid medications following orthopedic surgery investigators have developed a new multi-modal pain pathway. Investigators aim to compare this regimen with and without the inclusion of opioid medications. This study will be performed in a randomized, double-blinded, placebo-controlled fashion in patients undergoing primary total knee or total hip arthroplasty. Investigators hypothesize that the opioid devoid pathway will show equivalent pain scores to the pathway that includes opioids while also having less constipation, nausea, and vomiting following surgery. If successful, this would create a dramatic decrease in opioid consumption following orthopedic surgery while still providing appropriate pain relief to patients.
- Aim 1 will be to compare the postoperative pain levels both in the hospital setting as
well as daily for two weeks following discharge between patients in the opioid treatment
group and those in the non-opioid treatment group. This will be performed with clinical
exams while in the hospital and with phone surveys on discharge. Results will be
recorded using the Visual Analog Scale for pain scores.
- Aim 2 will be to compare the overall morphine equivalents used during hospitalization
between the opioid and non-opioid treatment groups. This will be calculated based on the
amount of intravenous breakthrough narcotic pain medication used in the hospital setting
(divided by the total number of post-surgery hospitalization hours to account for
varying lengths of stay). Investigators will also measure the total number of opioid
pills (these would be placebo pills for the non-opioid group) consumed during the first
two weeks post-discharge, and the post-surgery day on which opioid pills were
discontinued, and compare these outcomes between the opioid and non-opioid groups.
- Aim 3 will be to compare postoperative constipation, nausea, and vomiting between the
two treatment groups. This will be assessed with daily clinical examinations while in
the hospital and with daily phone surveys on discharge. Constipation will be recorded as
presence or absence, while nausea and vomiting will be measured using the Postoperative
Nausea and Vomiting Scale.
- Aim 4 will be to compare the length of post-surgery hospitalization between the two
treatment groups.
