Brief Summary:
The progressive aging of the general population cause increase in number of extensive and long surgeries in older patients. Age is a risk factor for perioperative myocardial ischemia and Postoperative Cognitive Dysfunction (POCD) The suggested study will deal with the above-mentioned complication in patients older then 65 years undergoing major non-cardiac surgeries.
It has been shown that Isoflurane and sevoflurane may have a cardio-protective effect after cardiac surgery involving cardio-pulmonary bypass, and it was recommended that isoflurane should be used in these cases. A question was raised but haven't been answered yet, whether this cardio-protective effect exists also in non-cardiac major surgery.
The aim of this study is to evaluate whether there is a difference in the occurrence of postoperative cognitive dysfunction and perioperative myocardial ischemia between total intravenous anesthesia using propofol and isoflurane based anesthesia.

Detailed Description:
The progressive aging of the general population cause increase in number of extensive and long surgeries in older patients.

A question was raised but haven't been answered yet, whether this cardio-protective effect exists also in non-cardiac major surgery.
The aim of this study is to evaluate whether there is a difference in the occurrence of postoperative cognitive dysfunction and perioperative myocardial ischemia between total intravenous anesthesia using propofol and isoflurane based anesthesia.
The suggested study is a randomized controlled study. 500 patients older then 65 years undergoing elective non-cardiac major surgeries will be studied.
On the day prior to surgery the patient will take a series computerized cognitive tests (Mindstream® cognitive health assessment, neurotrax®, Modiin, Israel). At the holding area before entering the operating room (OR) the patients will be randomly assigned to one of two study groups.
Group 1 -IA: anesthesia will be maintained using Isoflurane carried by O2/air. Group 2 - TIVA : anesthesia will be maintained with propofol. The patients will be followed for 3 months post-operatively. Cognitive function will be assessed 7 days and 3 months postoperatively using computerized tests and telephone interview.
