Parasternal and Adductor Canal Blocks in CABG

Starting soon · Not applicable

Conditions studied: Postoperative Pain, Regional Anaesthsia, Pain Management

In brief

This randomized controlled trial evaluates the effectiveness of different postoperative analgesic strategies in patients undergoing coronary artery bypass graft (CABG) surgery. Patients were allocated into three groups receiving either conventional analgesia alone, parasternal block in addition to conventional analgesia, or combined parasternal and adductor canal blocks with conventional analgesia. The study aims to compare postoperative pain scores, opioid consumption, and recovery outcomes among the groups in order to determine whether the addition of regional anesthesia techniques, particularly the combined block approach, provides superior analgesia and enhances postoperative recovery following CABG surgery.
