R.E.C.K versus Exparel for pain control during robotic kidney removal

Efficacy of Ropivacaine Epinephrine Clonidine Ketorolac (R.E.C.K) vs Exparel in Robotic Nephrectomy: a Randomized, Prospective Trial

Phase 3 Interventional Wake Forest University Health Sciences · NCT07092566

This will test whether intraoperative R.E.C.K or Exparel gives better pain control and reduces opioid use in adults having robotic partial or radical nephrectomy.

What this trial studies

This single-center, prospective, randomized phase 3 trial compares intraoperative R.E.C.K (ropivacaine with epinephrine, clonidine, and ketorolac) to Exparel (liposomal bupivacaine) in adults undergoing robotic partial or radical nephrectomy. Investigators will record intraoperative opioid use from the medical record and capture post-anesthesia care unit and inpatient pain scores using the Numerical Rating Scale along with oral and IV opioid and over-the-counter analgesic intake and length of stay. After discharge, participants will log time-stamped pain scores and self-administered analgesics in a provided take-home diary. The goal is to determine whether any improvements with Exparel justify its higher cost compared with the R.E.C.K cocktail.

Who should consider this trial

Good fit: Adults (≥18 years) scheduled for robotic partial or radical nephrectomy who can consent and are not chronic opioid users are ideal candidates.

Not a fit: Patients who are pregnant, have known allergies to the study drugs, are chronic opioid users, or are deemed unsuitable by the investigator are unlikely to benefit from participation.

Why it matters

Potential benefit: If successful, this could lead to better post-operative pain control or reduced opioid consumption and potentially shorter hospital stays for patients undergoing robotic nephrectomy.

How similar studies have performed: Other studies of liposomal bupivacaine and multimodal local anesthetic cocktails have shown mixed results, so a direct randomized comparison in robotic nephrectomy is relatively novel.

Inclusion Criteria:

1. Ability to understand and willingness to sign an IRB-approved informed consent
2. Age ≥ 18 years at the time of consent.
3. Planned robotic partial or radical nephrectomy

Exclusion Criteria:

1. Determined not to be a candidate to receive R.E.C.K or Exparel per the enrolling investigator

4. Uncontrolled intercurrent illness including, but not limited to, ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, or psychiatric illness/social situations that would limit compliance with study requirements as determined by the investigator.
