Consequences of Using Thoracic Epidural Analgesia for Coronary Artery Bypass Grafting

Investigators plan to conduct a comparative analysis of early postoperative complications of coronary artery bypass grafting with and without cardiopulmonary bypass in patients with independent risk factors for the development of postoperative complications (advanced age, diabetes mellitus, chronic kidney disease, obesity, chronic obstructive pulmonary disease) with various types of anesthesiology benefits (general anesthesia and thoracic epidural analgesia versus general anesthesia and opioids). Investigators predict a decrease in the risk of developing cardiac, respiratory, infectious and renal complications, a reduction in the duration of intensive care, inpatient treatment and mortality.
