| Abstract |
Basic research and animal studies have detected that volatile anesthetics provide some protection from myocardial ischemia, an effect called anesthetic preconditioning. Recent clinical studies have found that this preconditioning effect is of clinical relevance in patients undergoing coronary artery bypass surgery, resulting in better cardiac function and faster recovery after surgery, and in lower one-year morbidity. In patients undergoing non cardiac surgery, cardiac complications also are the major cause of perioperative morbidity and mortality. Myocardial ischemia frequently occurs during and immediately after non cardiac surgery in patients with coronary artery disease, and is a strong predictor of subsequent cardiac complications and death. Whether or not volatile anesthetics also provide clinically relevant protection from perioperative ischemia and subsequent cardiac complications in patients undergoing non cardiac surgery is unknown. Therefore, we will perform a prospective, randomized multi-center study to compare volatile with total intravenous anesthesia in patients at high cardiac risk who undergo major non cardiac surgery. We hypothesize that the use of a volatile anesthetic will reduce the incidence of perioperative ischaemia and myocardial injury, as indicated primarily by less ST-segment changes in the Holter ECG and, if there will be an effect, secondarily by lower incidences of elevated troponin T and NT-pro-BNP levels. And we hypothesize that the use of a volatile anesthetic will reduce the one-year incidence of cardiac complications and all cause mortality after surgery. The results of this study may apply to a huge percentage of surgical patients because coronary artery disease is the clinically most relevant co-morbidity, and its prevalence is expected to increase with the steadily increasing number of surgical patients aged 65 yr and older. |
