About this trial
The purpose of the study is to evaluate the efficacy of R.E.C.K (ropivacaine epinephrine clonidine ketorolac) vs Exparel during robotic partial and radical nephrectomy in a single institution, prospective, randomized trial. The study will evaluate post operative Numerical Rating Score (NRS) pain scores, post operative pain medication intake (opioids and over-the-counter pain medicines) and length of stay across the two patient cohorts. The findings will help to inform whether the increased cost of Exparel when compared to R.E.C.K is justified.

Trial outcomes
Primary outcomes
Area Under the Curve (AUC) of the Numeric Rating Scale (NRS) pain intensity scores through 7 days (168 hours) for participants receiving Exparel vs. R.E.C.K.
Assess pain intensity (evaluated by NRS) after surgery on the as response to the prompt: "On a scale of 0 to 10, where 0 = no pain and 10 = worst possible pain, how much pain are you having right now?" The AUC will be derived for each participant from self-reported pain scores and will be summarized by treatment group. Generalized linear models with main effect of treatment will be estimated to test for significant differences in AUC between the arms.
Secondary outcomes
Estimated difference in Numeric Rating Scale (NRS) pain intensity scores over 7 days for participants receiving Exparel vs. R.E.C.K.
Assess modeled daily pain scores using repeated measures analysis; the primary comparison is the treatment-by-time interaction effect. The NRS is a scale to evaluate pain in response to the prompt "On a scale of 0 to 10, where 0 = no pain and 10 = worst possible pain, how much pain are you having right now?"
Total postsurgical opioid consumption (morphine equivalent dose) over 7 days for participants receiving Exparel vs. R.E.C.K.
Total opioid consumption will be calculated for each participant as the sum of all administered opioid doses from Postoperative Day 0 through Day 7. All opioid doses will be converted to morphine equivalent dose (MED) using standard conversion factors. The total MED will be compared between treatment arms .
Estimated difference in postsurgical opioid consumption (in morphine equivalent dose) over 7 days for participants receiving Exparel vs. R.E.C.K.
Assess modeled daily postsurgical opioid consumption using repeated measures analysis; the primary comparison is the treatment-by-time interaction effect. Daily totals in morphine equivalent dose will be calculated for each participant.
Total postsurgical non-opioid pain medication consumption (in milligrams) over 7 days for participants receiving Exparel vs. R.E.C.K.
Total milligrams consumed for each for ibuprofen, acetaminophen, and naproxen will be calculated for each participant as the sum of the total milligrams consumed from Post Operative Day 0 trough Post Operative Day 7 and compared between arms. The total milligrams consumed will be compared between treatment arms.
Other outcomes
Proportion of participants experiencing any study -drug related adverse events within 30 days of surgery for participants receiving Exparel vs. R.E.C.K.
A binary variable indicating experience of at least one AE occurring within 30 days of administration of study drug will be determined for each participant. The proportions will be compared between treatment arms.
Proportion of participants experiencing any study -drug related Grade 3+ adverse events within 30 days of surgery for participants receiving Exparel vs. R.E.C.K.
A binary variable indicating experience of at least one Grade 3+ AE occurring within 30 days of administration of study drug will be determined for each participant. The proportions will be compared between treatment arms.
Proportion of participants experiencing any serious adverse events within 30 days of surgery for participants receiving Exparel vs. R.E.C.K.
A binary variable indicating experience of at least one SAE occurring within 30 days of administration of study drug will be determined for each participant. The proportions will be compared between treatment arms.
Proportion of participants experiencing any surgical complications within 14 days of surgery for participants receiving Exparel vs. R.E.C.K.
A binary variable indicating experience of at least one surgical complication occurring within 14 days of administration of study drug will be determined for each participant. The proportions will be compared between treatment arms.
