Heart and Lungs Protection Technique for Cardiac Surgery with Cardiopulmonary Bypass.

Introduction: Cardioplegic cardiac arrest with subsequent ischemic-reperfusion injuries can lead to the development of inflammation of the myocardium, leucocyte activation, and release of cardiac enzymes. Flow reduction to the bronchial arteries, causing low-flow lung ischemia, leads to the development of a pulmonary regional inflammatory response. Hypoventilation during cardiopulmonary bypass (CPB) is responsible for development of microatelectasis, hydrostatic pulmonary edema, poor compliance, and a higher incidence of infection.
