title: [Hemodynamic features during coronary bypass surgery on the working heart].
abstract: Changes in hemodynamics and blood oxygen transport function were studied during coronary bypass surgery (CBS) on the working heart under anesthesia with propofol and fentanyl. In patients operated on the working heart, the course of the basic stage of an operation was characterized by a moderate reduction in cardiac index and stroke volume due to the cardiac changes and immobilization, which resulted in cardiac compression and venous return deterioration. These impairments did not lead to worse oxygen-transportfunction and they were completely eliminated in the rehabilitative period. Analyzing the results of studies of troponin-T and creatinine kinase-MB showed that the procedure of coronary bypass surgery without using EKK had a less damaging effect on the myocardium. Analyzing the course of an early postoperative period indicated that the use of perfusionless technology substantially reduced needs for inotropic support, the time of artificial ventilation, and the length of stay at an intensive care unit.
