Analgesic Efficacy of Parasternal Block Versus Parasternal Plus Serratus Anterior Plane Block After Coronary Bypass Surgery

This single-centre randomized clinical trial will compare two regional anaesthesia techniques for postoperative pain control in adult patients undergoing elective coronary artery bypass grafting (CABG) with sternotomy. All patients will receive a bilateral parasternal block as part of routine multimodal analgesia. Patients will be randomized to receive either parasternal block alone or a combination of parasternal block and serratus anterior plane block. The primary objective is to evaluate whether adding a serratus anterior plane block improves postoperative pain scores compared with parasternal block alone. Secondary objectives include comparing opioid consumption, need for rescue analgesics, opioid-related side effects, and length of stay in the intensive care unit and hospital.
