Clinical Trial Summary
This is a randomized controlled trial. Patients will be randomly assigned to either the
control or treatment group, with equal allocation using block randomization. The primary null
hypothesis is that a combination sufentanil and buprenorphine based pain control regimen will
not result in lower morphine equivalent requirements for pain control when compared to a
classic fentanyl and hydromorphone based regimen. The secondary working hypothesis is that
the patient satisfaction survey mean satisfaction scores will be higher in the buprenorphine
and sufentanil treated group when compared to the classic fentanyl and hydropmorphone treated
group. The secondary null hypothesis is that the patient satisfaction surveys mean scores
will not be significantly different in the buprenorphine and sufentanil treated group when
compared to the classic fentanyl and hydropmorphone treated group. The tertiary working
hypothesis is that the patients will have significantly lower rates of relapse as defined by
follow up with their home suboxone clinic at 2 and 4 weeks. The tertiary null hypothesis is
that patients have equivalent rates of relapse as defined by follow up with their home
suboxone clinic at 2 and 4 weeks.
Description:
After determining the patient qualifies for the study, the patient would then be taken
through the informed consent process by one of the co-investigators in the orthopedics group
at West Virginia University. The co-investigator would then use a block randomization table
to assign the patient to standard (control) treatment versus IV buprenorphine plus IV
sufentanil treatment group. The appropriate order set would then be selected in EPIC by the
anesthesia department depending on the results of the randomization. Induction of anesthesia,
anxiolysis and hypnosis would be at the discretion of the assigned anesthesiologist. Ketamine
would be excluded as an option for maintenance of general anesthesia due to its profound
analgesic properties. The control group would receive fentanyl 0.5mcg/kg q10 minute PRN,
ketorolac 0.5mg/kg up to 30mg max IV, and acetaminophen 1000mg IV for pain control
intraoperatively. The patient would then be treated with hydromorphone 0.005mg/kg q10 minutes
(max single dose 1mg) in the post-anesthesia recovery unit (PACU) until their pain was
described as manageable or the patient reported they were comfortable. The patient would then
receive hydromorphone 0.005 mg/kg (max single dose 1mg) q1hr PRN, 1 gram acetaminophen IV
scheduled q6hr, and methocarbamol 750mg QID following discharge from the PACU and transfer to
the hospital floor. The patient would then be converted to oxymorphone 10mg (Roxicodone) q4hr
PRN and 975 mg PO APAP scheduled for pain control on hospital day number 2. The patients
would receive their home dose of suboxone on hospital day number 2. On hospital day number 3,
patients would be transitioned to an increased dose of their Suboxone for pain control in
preparation for discharge. At any time during admission the patient feels as if their pain is
uncontrolled and comfort could not be achieved, the anesthesia pain service would evaluate
the patient and order sufentanil PCA while discontinuing other opioid therapy. This treatment
would be considered a rescue therapy and the patient would be removed from the study arm. The
buprenorphine-sufentanil group would receive sufentanil 0.01 mcg/kg q10 min PRN, IV ketorolac
0.5mg/kg up to 30mg max and IV acetaminophen 15mg/kg up to 1000mg for pain control
intraoperatively. In the PACU, IV buprenorphine 0.3mg IV q30 minutes would be given as the
first line choice for pain control for 3 doses. IV PCA sufentanil would be used as a second
line therapy if patient comfort is not achieved by IV buprenorphine alone. The patient would
then receive 0.3 mg buprenorphine IV Q6hr PRN, scheduled IV acetaminophen 1 gram for 24 hours
and methocarbamol 750mg QID after discharge from the PACU and transfer to the hospital floor
on hospital day 1. The patient would then be converted to buprenorphine 2mg q6hr PRN and 975
gram PO APAP scheduled for pain control on hospital day number 2. The patient would receive
their home dose of suboxone starting on hospital day number 2. On hospital day number 3,
patients would be transitioned to an increased dose of their suboxone for pain control as
determined by psychiatry in preparation for discharge.
Post-operatively both groups would receive psychiatric consult and PT/OT consult. Data on
opioid consumption for the intra-operative period and post-operative period as well as
post-operative pain scores will be recorded and analyzed for comparison. Morphine equivalents
used per hour and per 24 hours would be analyzed as a primary endpoint. A patient pain
satisfaction survey would be distributed and collected from both groups on hospital day #3.
Data on length of stay, pain scores, and ED readmission for pain control would also be
recorded and analyzed. Patients would be discharged on increased dose suboxone for 2 weeks
for post-operative pain control. The patients would then transition back to their normal
suboxone maintenance dose. A follow up phone call would be made at 2 and 4 weeks to the home
clinic to assess patient follow up and potential relapse.
Univariate statistics (e.g. mean, median, standard deviation, interquartile range) will be
used to summarize the collected data. Balance between the two groups for key patient
variables will be assessed using a two-sided two-sample t-test using unequal variances and
the Welch modification to the degrees of freedom. For categorical variables, the Chi-square
test will be used. If non-parametric tests or exact methods are required, the Mann-Whitney U
test and the Fisher exact test will be used as appropriate.
