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.
