A Comparative Evaluation of Post-operative Pain Management Using Erector Spinae Plane Block and Oblique Transverse Abdominis Plane Block in Patients Undergoing Laparoscopic Cholecystectomy.

Introduction Acute pain following laparoscopic surgeries interferes with the rehabilitation of the patient. Knowledge about the pain pathway from a particular area helps in blocking pain transmission at different sites. Ultrasonography (USG)-guided peripheral nerve blocks help in controlling pain better than non-steroidal anti-inflammatory drugs (NSAIDS) and opioids since they directly act by interrupting the pain pathway and interfere less with the physiology of the body.
