Comparison of Ultrasound guided External oblique intercostal plane block vs subcostal transversus abdominis plane block for laparoscopic cholecystectomy surgeries: a prospective randomised controlled clinical study

All eligible patients will be well explained about the study protocol and interventions and allocated into two groups. Patients will be taken to the operating room, and anesthesia will be induced as per institutional protocol. After the surgery is completed, one group will be given external oblique intercostal plane block, and in the other group, subcostal transversus abdominis plane block will be given with ultrasound guidance. Then, the patient will be reversed from anesthesia and shifted to the postoperative recovery room and monitored.

Postoperative pain will be assessed with the Visual Analogue Scale for the first 24 hours. If the patient complains of pain (Visual analogue scale score more than 4), rescue analgesia (tramadol and diclofenac) will be given, and time will be noted. This data will be analyzed statistically. Finally, the primary outcome (time taken for first postoperative rescue analgesia) will be compared in both groups.
