Summary
This study compares two drug combinations (ketamine-lidocaine vs ketamine-fentanyl) used to put patients to sleep before heart bypass surgery. The goal is to see which combination better maintains blood flow to the brain during the procedure. The study includes 40 adults with coronary artery disease and weak heart pumping function who are scheduled for elective bypass surgery.
