Protection against cardiac ischemia/reperfusion injury is the basic objective in open heart surgery, and it may be achieved by pharmacological preconditioning or Postconditioning. In this study, we aimed to compare the effects of two different anest
hetic techniques (inhalation and total intravenous anesthesia) on ischemia-reperfusion injury in Coronary Artery Bypass Graft surgery. 80 CABG patients were randomly assigned into one of tow groups: Group A Sevoflurane (n=40) and Group B total intravenous anesthesia (n=40) with Propofol . data of hemodynamic monitoring and inotrops using were recorded. Arterial blood samples were taken in the preoperative period (T0), 12th hours (T1) ,24th hours (T2) and 48th hours postoperatively, and Troponine I levels were measured . The time of ventilation, ICU and total hospitalization were recorded .
Postoperative levels of troponine I were significantly lower in the Sevoflurane group with less using of inotrops and less staying in the ICU post-op . We conclude that the use of a volatile anesthetic regimen in CABG surgery associate with better preservation of myocardial function and a reduced postoperative release of
troponine I.
