[Disorders in blood rheological properties in the post-resuscitation period after the agonal state].
It has been discovered in experiments on anesthetized dogs that the early postresuscitation period following agony after a two-hour hypovolemic hypotension was characterized by pronounced disturbances of blood rheological properties: blood viscosity was significantly increased as compared with initial values under the shift rate 1.34 s-1; the limit of blood fluidity was twice as increased. Insignificantly changed was the magnitude of hematocrit following the recovery of the blood volume. Infusion of polyglucin (20-25 ml/kg) promptly after the blood volume recovery and on the first day after it (10 ml/kg) decreased the hematocrit magnitude to 0.26 l/l (days 5-7) but did not make blood fluidity return to normal. A significant increase of blood viscosity and fluidity could be observed for 1-3 months after resuscitation, the hematocrit magnitude being equal to 0.55 l/l instead of 0.47 l/l in an initial state (P less than 0.005).
