[The use of the Autotrans BT 795/P apparatus in surgery with artificial circulation].

The authors assess a possibility of the use of the BT 795/P outfit for aortocoronary shunting in 120 patients with coronary heart disease. Emphasize a considerable decrease in the requirement for donor's blood transfusion to patients undergoing intraoperative blood reinfusion by means of the BT 795/P outfit.

[Specific proteinase plasma sorption in surgery with artificial blood circulation].

Cardiosurgery with artificial circulation (AC) is attended with activation of plasma cascade proteolytic systems, which leads to homeostatic disturbances and postoperative complications. AC with the use of specific proteinase plasma sorption in a column with sepharose-immobilized acid-base proteinase inhibitor from human urine prevents activation of proteinase in the plasma. Application of specific plasma sorption facilitates rapid restoration of the plasma protein concentration lowered during AC, improves the course of the postoperative period, and reduces the risk of pulmonary, cardiovascular, and nervous complications.

[Variants of procedures of artificial blood circulation and the proteinase activity of the blood].

The use of a "Cell-Saver" technique prevented hyperproteolysis and deletion of proteinase inhibitors in the blood plasma of patients during cardiopulmonary bypass. The technique also improved the course of the postoperative period, decreased the incidence of lung complications and prevented effectively postoperative bleedings. A prognostic value of alpha 1-proteinase inhibitor to trypsin activity ratio in the blood plasma of patients subject of cardiopulmonary bypass surgery has been demonstrated.

[Artificial circulation in microsurgery of the coronary arteries].

Results of 69 aortocoronary bypass operations with the use of microsurgery equipment were analysed. Perfusion was performed under conditions of constant flow, which made it possible to avoid transmissive pulsation, making difficulties for creating microanastomoses. One venous double opening canule was used with no drainage of the left ventricule, which made cannulation easier and created optimal technical conditions for the surgeon.
