RESUMO
OBJECTIVE: to study potantial of remote ischemic preconditioning (RIP) as method of cardioprotection during coronary artery bypass surgery with cardiopulmonary bypass (CPB) and anesthesia with propofol. MATERIALS AND METHODS: We included in this study 87 patients (7 were excluded) with ischemic heart disease, hospitalized in the clinic of aortic and cardiovascular surgery of the I. M. Sechenov First Moscow State Medical University clinical hospital â 1. All patients had indications for direct myocardial revascularization by coronary artery bypass surgery. One day before operation patients were randomly assigned to 2 groups depending on preparation scheme: main group of RIP and the control group. The frequency of complications during surgery and in the postoperative period was assessed. Troponin I level was measured before, and in 2 and 24 hours after surgery. The level of lactate in the venous blood was measured before and after surgery. RESULTS: Numbers of intraoperative and early postoperative complications in the main and control groups were similar. There were no differences between groups in troponin I and lactate levels after surgery. CONCLUSIONS: Remote ischemic preconditioning has no effect on the outcome of coronary artery bypass surgery with cardiopulmonary bypass and anesthesia with propofol.
