[The microcirculatory bed and the blood rheological properties in the acute period of severe craniocerebral trauma].

The microcirculatory channel of the bulbo-conjunctival vessels and the blood rheological properties were studied in 128 patients in the acute period of a severe craniocerebral trauma. Disorders of microcirculation and hemorheology were detected in the early periods, reached maximum by the 3rd-7th day and reflected the condition of cerebral circulation. Progressive growth of blood fibrinogen concentration, development of intravascular aggregation of red cells and their stasis, slow and bead-like blood flow, drastic dilatation of venules and capillaries with reduction of their number and absence of response to vasoactive agents are signs of an unfavourable outcome of traumatic disease.
