[Effects of intraoperative reservation and reinfusion of autologous blood on the function of lungs in patients with ischemic heart disease].

A retrospective examination of 127 patients has been performed who underwent operations of coronary bypass under conditions of hypothermic extracorporeal circulation. It was shown that both the reservation of autoblood (volume about 10% of circulating blood) and the following reinfusion failed to result in a substantial change of the lung functions. The reservation-reinfusion of autoblood in IHD patients operated on by direct revascularization of the myocardium under conditions of extracorporeal circulation did not influence the indices of ventilation (the volume of functional dead space), pulmonary blood flow (fraction of venoarterial intrapulmonary shunt, mean pressure in the pulmonary artery), diffuse capacity of the lungs (the arterial/alveolar ratio).
