Randomized Controlled Trial Comparative Study Clinical Trial[A comparative study of the effectiveness of 5% human albumin and 10% hydroxyethyl starch (HAES-steril) for correcting hemodynamics and O2 transport in surgical interventions].
Forty patients subjected to cavitary operations were examined. A high risk of hemodynamic disorders necessitated invasive monitoring; with this aim in view a catheter was inserted for measuring arterial pressure and the Swan-Ganz catheter for measuring the pressure in the pulmonary artery, in which helped monitor the hemodynamics and oxygen transport in the course of hypervolemic hemodilution. Plasma substitutes (one of two) were selected at random. ⋯ Loss of plasma caused by surgical intervention was better compensated for with synthetic colloid solutions, such as 10% HAES-steril (Fresinium, Oberurzel, Germany), provided that plasma protein level was at least 3-4 g/dl. The effect of 10% HAES-steril as regards the increase of circulating blood volume is 145%. Due to the hyperoncotic direction of its action it has a positive impact on the hemodynamics and oxygen transport and is needed in lower doses than other colloid solutions.

Comparative Study[Fiber optics oximetry of blood in the upper bulb of the internal jugular vein in heart surgery].
The authors assess the potentialities of a new method; fiber optic oxyhemometry of the blood flowing from the brain (at the level of the upper bulb of the internal jugular vein) during heart surgery. They demonstrate a sufficiently high accuracy of the method. Using it during cardiosurgical operations under artificial circulation, they found it highly informative and sensitive to even suddenly emerging and short-term changes in the ratio of oxygen delivery/consumption by the brain.
