Rectointercostal Plane BlockPort-Site Local Anesthetic Infiltration
Rectointercostal Plane Block: Ultrasound-guided unilateral right-sided rectointercostal plane block (RICPB) will be performed at the end of surgery before emergence from anesthesia. A total of 30 mL of 0.25% bupivacaine will be injected into the rectointercostal plane under ultrasound guidance.
Port-Site Local Anesthetic Infiltration: Conventional port-site local anesthetic infiltration will be performed at the end of surgery according to the study protocol to provide postoperative analgesia.
Study summary
This prospective randomized controlled trial is designed to evaluate the analgesic efficacy of ultrasound-guided rectointercostal plane block (RICPB) in patients undergoing elective laparoscopic cholecystectomy. Patients will be randomized to receive unilateral right-sided RICPB at the end of surgery. Postoperative opioid consumption, Numeric Rating Scale (NRS) pain scores, and postoperative complications will be assessed to determine the effectiveness of RICPB in postoperative pain management.
