[Oxygen metabolism with low hematocrit levels in the course of guided hemodilution procedure in cardiosurgical patients]. / Obmen kisloroda v usloviiakh nizkogo gematokrita pri provedenii upravliaemoi gemodiliutsii u bol'nykh kardiokhirurgicheskogo profilia.

Influence of hemodilution on the oxygen metabolism in patients, operated, using the artificial blood circulation apparatus, was studied up. Factors, determining the oxygen delivery to tissues, was estimated, correlational links between the blood rheological properties and its oxygen--transporting function were established. Experience of application of apparatus Aeprex, promoting the oxygen delivery to tissue improvement and the need in donor's blood lowering, performing operations, using the artificial blood circulation apparatus.

[The myocardial defense in the arterial bypass surgery]. / Zashchita miokarda pri vypolnenii operatsii arterial'nogo perekliucheniia.

The experience of myocardium protection during performance of operation of arterial switching (AS) in 57 patients was analyzed. In 30 patients cardioplegic solution was infused at one moment, what had advantages in comparison with its multimoment infusion.

[Gas embolism of cerebral vessels in surgery with extracorporeal circulation (clinical and pathophysiological aspects)]. / Gazovaia émboliia sosudov golovnogo mozga pri operatsiiakh s iskusstvennym krovoobrashcheniem (klinicheskie i patofiziologicheskie aspekty).

Examination of 746 cardiosurgical patients revealed a statistically significant dependence between the frequency and degree of gas embolism recorded by the ultrasonic method during the operation and the probability and severity of cerebral circulatory disorders in the postoperative period. Experiments on 13 dogs showed the possibility of gas bubbles passing through the microcirculatory channel of the brain. Under satisfactory hemodynamic conditions up to 1/4 of the volume of air which has entered the cerebral arteries is "washed out" from the cerebral venous system. The revealed fact is most important in explaining the discrepancy between the frequency of gas embolism recording during the operation and the frequency of acute cerebral circulatory disorders in the postoperative period.

[Anesthesiologic management in experimental surgical interventions on the heart and major blood vessels]. / Anesteziologicheskoe obespechenie éksperimental'nykh operativnykh vmeshatel'stv na serdtse i magistral'nykh sosudakh.

On 26 mongrel dogs with a mass of 8-26 kg, 5 methods of anesthesiologic maintenance of operative interventions on the heart and major vessels were studied. An optimal method has been found.
