[Trauma to the blood during assisted circulation].

Trauma inflicted to blood in different method of assisted circulation was studied in experiments and in the clinic. Morphological disturbances of red blood cells and changes in their aggregation properties were revealed. Left ventricular shunt and aorto-aortic counter-pulsation are attended with increased aggregation properties of blood platelets. Aorta-aortic counter-pulsation causes a greater damaging effect than shunting of the left ventricle. Counter-pulsation by means of a balloon pump is attended with least hemolysis.

[Noninvasive assisted blood circulation].

The experience of the use of noninvasive assisted circulation in patients with cardiac pathology is summarized. It has been demonstrated that rhythmic pneumo-compression of the lower extremities, abdominal compression, muscular electrical stimulation of the lower extremities and the abdomen have a pronounced effect on circulation compartments with low pressure. All the above pre-determines the role of these techniques in the management of cardiac failure and in intensive care.

[Abdominal compression as a method of resuscitation and assisted circulation].

Experiments on animals have been carried out to investigate the hemodynamic changes during manual abdominal compression (AC) under conditions of heart fibrillation and acute heart failure. The possibility to increase the efficacy of left ventricular bypass (LVB) has been studied. Manual AC enhanced the pressure and blood flow in low-pressure compartments and increased aortic systolic and diastolic pressure. It has been also noted that LVB efficacy was increased in simultaneous assisted perfusion and abdominal compression. The first clinical data confirm the experimental findings.
