INTRODUCTION
Off-pump coronary artery bypass surgery (off-pump CABG) has become a common surgical procedure. An important goal in the perioperative management of patients undergoing off-pump CABG, is to maintain cardiac function, organ perfusion and oxygen delivery. Recent and innovative approaches in cardiac surgery have led to complement the conventional objectives of anesthesia such as: hemodynamic stability, coronary perfusion parameters, and adequate anesthetic depth. New objectives are added after cardiac surgery, such as: rapid recovery of brain activity, spontaneous respirations and a minimal load on the intensive care unit (ICU). The benefits of early extubation include improved cardiac function and patient comfort, reduction in respiratory complications, as well as an ease in management.
