Outcome Measures
Primary Outcomes (3)
Postoperative Pain Scores
To examine changes in pain scores daily from the day of surgery to the hospital discharge day.
through study completion, an average of 6 days
Postoperative Opioid Consumption
To compare opioid consumption after surgery between the buprenorphine/naloxone group and the standard medication regiment group.
through study completion, an average of 6 days
Length of Hospital Stay
To compare the length of hospital stay after surgery between the buprenorphine/naloxone group and the standard medication regiment group.
through study completion, an average of 6 days
Study Arms (2)
Buprenorphine/Naloxone
ACTIVE COMPARATORSubjects will take a maximum dose of 4 mg buprenorphine and 1 mg naloxone with concurrent administration of other intravenous or oral opioids needed.
Standard Medication Regiment
NO INTERVENTIONSubjects will take conventional intravenous or oral opioid management.
Interventions
Subjects will be randomized into one of the treatment groups and will follow the assigned medication schedule for the length of their hospital stay, at least 6 days.
Eligibility Criteria
You may qualify if:
- Opioid tolerance, defined as the daily use of greater than or equal to 60mg of oral morphine or an equianalgesic dose of any other opioid for more than 7 days immediately prior to the surgery
- Undergoing orthopedic or general surgery
- years of age or older
- Willing and able to adhere to the study protocol and follow-up schedule
- Able to provide written informed consent to participate in the clinical trial
- If female and of childbearing potential, agree to use an effective method of birth control approved by the study investigators throughout the study
You may not qualify if:
- Buprenorphine or buprenorphine/naloxone use in the last two weeks
- Patients receiving pre-, intra-, or post-operative regional blocks or neuraxial anesthesia
- Patients receiving postoperative ketamine or lidocaine boluses or infusions
- Patients receiving postoperative nonsteroidal anti-inflammatory drugs (NSAIDs) for pain control
- Diagnosis of severe medical or psychiatric conditions contraindicated for bup/nx treatment
- Liver disease, including clinically significant transaminitis, active hepatitis infection, cirrhosis with evidence of impaired synthetic function
- Anticipated deterioration of health due to discontinuation of medications that are contraindicated with bup/nx
- Positive pregnancy test for women of childbearing potential
- Known allergy or sensitivity to bup/nx
- Anticipation that the subject may need to initiate pharmacological treatment during the trial that is deemed unsafe by the study physician or could prevent study completion
- Current participation in additional pharmacologic research study
- Active suicidal ideation as determined by PI or study clinician
