Results of controlled clinical examination of intraoperative reinfusion of blood, taken from pleural cavity in the slow and fast conditions

Abstract

The controlled clinical examination showed that the decay of erythrocytes and leucocytes under blood reinfusion in experimental control (EC) after intraoperative blood reinfusion (IO RIC) is 35% in slow blood reinfusion, and 48% in fast blood reinfusion. Osmotic resistance is decreased by 3 times. In fast technical exfusion the blood-hemolysis is more than 28%, what needs to be taken into account in carrying out technical IO RIC. According to CCI results, the faster the technical exfusion is done, the more significant is decrease of protein and bilirubin; besides, in both EC and clinical control. There is a higher concentration of K+, residual nitrogen and urea in blood collected during fast technical exfusion. According to CCI results, the number of thrombocytes is reliably decreased, especially due to the fast blood exfusion. The process of aggregation in these conditions is reliably slowing down; besides, in the fast blood exfusion mode it slows down twice in contrast to the controlled one. The period of plasma recalcification is surely decreased to 40% due to the high-speed mode of blood exfusion in comparison to the controlled indexes, which is 3 times higher than in the application of the slow blood aspiration.
