METHOD OF INTRAOPERATIVE EXTRACORPORAL HEATING OF PATIENTS IN OPEN-HEART OPERATIONS UNDER CONDITIONS OF PERFUSION-FREE HYPOTHERMAL PROTECTION

摘要

cardiosurgery and cardioanesthesiology. SUBSTANCE: on completion of intracardiac stage of operation, before closing of atriotomy access, separate cannulation of vena cava inferior and auricle is performed. After removal of air from heart cavities, aorta occlusion is discontinued and extracorporal heating of patient is started by blood intake from vena cava inferior to heat exchanger for perfusion cardioplegia. Heated blood is returned to auricle. Blood perfusion velocity in extracorporal circuit is not in excess of 10% of rated blood flow velocity depending on surface area of patient body. Patient is heated up to temperature of 34 C in rectum and 36 C in esophagus. Cannulas are withdrawn successively from vena cava inferior and auricle. Method provides for attaining early efficient heart action, prevention of complications and reduced terms of patient rehabilitation in postoperative period. EFFECT: higher efficiency. 1 ex
