简要总结
Non-cardiac surgery is associated with significant cardiac morbidity and mortality. Volatile anesthetics have a cardioprotective effects which results in preservation of left ventricular function and lower troponin I levels. Lower troponin release has been correlated with better long term event free survival in both cardiac and non cardiac surgery. A recently completed meta-analysis suggests that sevoflurane is a superior volatile agent. The evidence of a cardioprotective effect in non-cardiac surgery is lacking. Base on the current literature, we intend to evaluate the protective potential of sevoflurane versus propofol anesthesia in high risk patients undergoing elective non-cardiac procedures.
Hypothesis: The use of Sevoflurane as a general anesthetic reduces postoperative troponin release, the incidence of myocardial infarction and/or long term morbidity in patients at low to moderate risk of postoperative cardiac complications, who are undergoing noncardiac surgery.
