Liposomal Bupivacaine vs Ropivacaine for TAPBs

Summary

Few studies have compared the efficacy of ultrasound (US)-guided TAP blocks with Liposomal bupivacaine(LB) versus ropivacaine in reducing postoperative opioid usage in patients undergoing laparoscopic lower abdominal tumor Resection. Therefore, we are conducting this prospective, randomized controlled trial to compare the postoperative analgesic effects of LB and ropivacaine for TAP blocks among patients undergoing laparoscopic colorectal procedures.

Eligibility

Inclusion Criteria:

1. Patients undergoing laparoscopic resection of lower abdominal tumors
2. ASA grade II-III
3. Age: 18-70 years.

Exclusion Criteria:

1. (1) The patient does not agree to participate in the clinical study
2. (2) The patient has a clear history of opioid tolerance or allergy
3. (3) The patient has a history of local anesthetic allergy
4. (4) Previous history of dementia, mental illness or other central nervous system diseases
5. (5) Have a history of chronic pain or are taking opioids and other analgesics
6. (6) Patients are generally in poor condition with a history of serious diseases of cardiovascular system, respiratory system, digestive system, urinary system or central nervous system, and may not survive for more than 3 months
7. (7) The patient had any of the following conditions in the 12 months before surgery: myocardial infarction, severe/unstable angina pectoris, coronary artery bypass grafting, congestive heart failure, cerebrovascular accident, pulmonary embolism
8. (8) Pregnant women
9. (9) Unable to cooperate with follow-up or poor compliance
