Liposomal Bupivacaine/Bupivacaine in Rectus Sheath Blocks Versus Ropivacaine in Rectus Sheath Blocks And Catheters
United States14 participantsStarted 2023-10-18
Plain-language summary
The goal of this pilot study is to compare single shot rectus sheath blocks of liposomal bupivacaine/bupivacaine mixture to bilateral rectus sheath catheters infused with ropivacaine (standard of care at our facility) in patients undergoing vascular surgery with an open mid-abdominal laparotomy incision. This study will assess the safety and feasibility of this approach compared to standard of care.
Participants will receive either a single dose of liposomal bupivacaine/bupivacaine mixture intraoperatively at the end of surgery through bilateral rectus sheath blocks (LB/B group) or the standard of care ropivacaine intraoperatively at the end of surgery through bilateral rectus sheath blocks with the insertion of bilateral RS catheter for continuous ropivacaine infusion plus repeated daily boluses (Catheter group; standard care). They will be assessed for differences in the rate of postoperative complications, resources consumed with each intervention, as well as postoperative pain scores, opioid consumption, hospital and PACU length of stay, patient's satisfaction, and quality of recovery, and hospital length of stay.

Inclusion criteria
✓. Patients aged 18-80 years
✓. Patients scheduled for elective vascular surgery with an open mid-abdominal laparotomy incision, including abdominal aortic aneurysm repair surgery (AAA), mesenteric artery bypass surgery, and aortobifemoral bypass surgery for aortic occlusive disease.
✓. Patients who are able to speak and read English
✓. Patients with American Society of Anesthesiology (ASA) physical status score I-IV
✓. Patients who are admitted to the hospital and are incidentally discovered to require any of the aforementioned surgeries, being asymptomatic for vascular issues, and having their surgery scheduled no sooner than three days after admission, are also considered eligible.
Exclusion criteria
✕. Emergency vascular reconstruction surgery., patients admitted to the hospital due to symptoms directly associated with their vascular condition, such as severe abdominal pain or a ruptured aneurysm causing bleeding, will be excluded.
✕. Patients with contraindications to RSB, including but not limited to anatomical abnormality, previous surgical intervention that limits or prevents receiving bilateral RSBs, or infection at the injection site.
What they're measuring
1
The cost of care during hospitalization.
Timeframe: From the time of the blocks until the date of discharge, assessed as 2 weeks
2
The occurrence of block-related and catheter-related complications, or local anesthetics-related adverse events up to hospital discharge or up to one week.
Timeframe: From the date of the block until the date of discharge, assessed up to 1 week
✕. Weight \< 40 kg, as a combination of 20 mL of Bupivacaine 0.25% with 30 mL of LB is greater than the maximal dose allowed, given concern for local anesthetic toxicity.
✕. Patients who take long-acting opioid medication, or on continuous opioid use \> 50 MME per day for at least 30 days within 90 days prior to surgery.
✕. Patients who have chronic pain syndrome with a recent preoperative consultation with the chronic pain service. Also, patients with distant metastatic cancers (e.g. bone, lung, brain) confirmed by CT scan.
✕. Patients with current substance abuse, or history of substance abuse within 3 months, this includes any illicit drugs (not including marijuana) or excessive alcohol consumption as defined as 4 or more drinks per day or 8 or more drinks per week for women and 5 or more drinks per day or 15 or more drinks per week for men.
