Coronary Artery Bypass Surgery

The study aims to evaluate the analgesic efficacy of paravertebral block, mobilization speed, respiratory functions, and complication rates in patients who have undergone cardiac surgery and are monitored in the intensive care unit during the postoperative period.

Coronary artery bypass graft (CABG) surgery is still the standard treatment of coronary revascularization for patients with severe coronary artery disease (CAD). Graft patency, together with completeness of revascularization, is a major determinant of long-term outcome following CABG. The surgical procedure elicits a persistent systemic inflammatory response associated with the activation of the hemostatic system leading to perturbation of endothelial and vascular function and activation of platelets and leukocytes. All of these events are the main players responsible for the early and late graft failure in a significant percentage of patients.

This study is to evaluate the effectiveness of Transesophageal Lung ULtrasound (TELUS) guided recruitment maneuver to reduce lung atelelectasis in cardiac surgery. This is a RCT trial involving a cardiac patient that requiring used of cardiopulmonary bypass machine intraoperatively. These patient will be randomized into either intervention group or control group.
