[Transfusion supply optimization in multiple-discipline surgical hospital].

Aim: To define optimal variant of transfusion supply of hospital by blood components and to decrease donor blood expense via application of blood preserving technologies.

Material And Methods: Donor blood components expense, volume of hemotransfusions and their proportion for the period 2012-2014 were analyzed.

Results: Number of recipients of packed red cells, fresh-frozen plasma and packed platelets reduced 18.

[Effects of features of extracorporal circuits on thrombocyte hemostasis, the fibrinolysis system, and development of hemolysis].

The article contains data which demonstrate that use of extracorporal circuits with special coating ("safe-line" and "duraflow") improves preservation of thrombocyte functional activity, and lowers activation of the fibrinolysis system in postoperative period, which results in decrease of postoperative blood loss. Use of heat exchangers with polypropylene coating is less traumatic to blood cells, and thus lowers frequency and degree of hemolysis.

[Implementation of modern principles of blood saving methods at cardiac surgery under extracorporeal circulation].

The introduction of principles of bloodless surgery into different areas of practical medicine is favoured by not only risks from donor blood transfusion, but also by the results of the researches dealing with the body's adaptation to acute anemia, with the determination of its allowable limits, and with much experience with bloodless operations used in Jehovah's Witnesses. The present study was undertaken to make a scientific-and-practical assessment of actual own blood funds and their introduction in order to decrease or refuse to use donor blood at cardiac surgery under extracorporeal circulation (EC). A retrospective analysis of hemotransfusion policy in 1993-2001 was conducted in over 2000 patients operated on under EC for coronary heart disease, acquired and congenital cardiac diseases at the Open Cardiac Surgery Department, Russian Surgery Research Center, Russian Academy of Medical Sciences.

[Currently available blood saving methods in a patient at cardiac surgery under extracorporeal circulation].

Different blood saving methods are analyzed in 2000 cardiac surgical patients undergoing coronary and vascular bypass surgery in 1993 to 2000. The basic blood saving methods are as follows: intraoperative autoreinfusion (normovolemic thermodilution), reinfusion of the patient's blood, preoperative autologous plasma donation in combination with aprotinine, aminocapronic acid, etc. An analysis revealed a decrease in homologous blood components intraoperatively.

[The terminology and classification of the polymer components of ammunition].

Variant of general classification of ammunition polymer components (APC) is suggested and terminology of trace-forming parts of some APC for practical use is presented. The author shows mechanism of APC substance trace formation upon the obstacles and gives their terminology.
