Randomized Controlled Trial[Effect of the combined hypertonic colloidal solution HyperHeas on hemodynamic and oxygen transport parameters, intracranial pressure, and cerebral oxygenation].
The paper gives the results of a clinical study of the effect of the new combined hypertonic colloidal and hypertonic solution HyperHaes (Frezenius-Cabi) on the parameters of systemic hemodynamics (invasive evaluation by means of a Swan-Ganz catheter), systemic oxygen transport, intracranial pressure (ICP) (lumbar spinal fluid pressure), and cerebral oximetry (INVOS 5100) in neurosurgical patients. The paradoxical effect was found as acute blood pressure lowering and elevated ICP on the beginning of solution infusion (the vasodilator effect of a distinctly hyperosmolar agent). In all other respects, HyperHaes is an ideal agent for volumetric compensation in neurosurgical patients.

Randomized Controlled Trial Comparative Study[Tactics of infusion therapy in the acute period of intracranial hemorrhages].
The paper deals with the determination of infusion therapy tactics in critically ill patients with intracranial hemorrhages on the basis of invasive measurements of systemic hemodynamics. The routine hemodynamic parameters (blood and central venous pressures, heart rate) are noted to fail to assess the volemic status of the patients in full. Unlike the use of colloidal solutions, infusion therapy with physiological sodium chloride is not shown to correct systemic hemodynamics. It has been ascertained that in acute intracranial hemorrhages, infusion therapy with crystalloidal solutions leads to impaired pulmonary gas exchange and increased pulmonary extravascular fluid and the use of a combination of crystalloidal solutions and a colloidal agent in a 1:1 ratio can correct the volemic status of the patients and is not followed by lung dysfunctions.
