[Effects of infusion therapy during anesthesia on circulating blood volume, osmolality and colloid-osmotic pressure]. / Vliianie infuzionnoi terapii vo vremia anestezii na ob'em tsirkuliruiushchei krovi, osmolial'nost' i kolloidno-osmoticheskoe davlenie.

The problems of infusion therapy during anesthesia and surgery, relevant for clinical practice, have been reviewed. The changes in circulating blood volume, plasma osmolality and colloid-osmotic pressure have been studied depending on quantitative and qualitative structure of the infusion therapy as well as on the duration of surgical intervention. The dependence observed indicates that infusion therapy during anesthesia and surgery must not be considered a routine procedure. The data obtained will help practicing anesthesiologists to choose the right technique.

[Venous hemodynamics in chronic occlusive diseases of arteries of the lower extremities]. / Venoznaia gemodinamika pri khronicheskikh obliteriruiushchikh zabolevaniiakh arterii nizhnikh konechnostei.

The authors have revealed a gradual development of venous hypertension and deceleration of the rate of venous blood flow in the damaged extremities in chronic obliterative arterial diseases. Decompensation of arterial hemodynamics is accompanied by the development of pronounced venous congestion with reduced venous pressure and tension. This may cause the incompetence of the deep venous valves.
