Abstract

In experiments on cats anesthetized with pentobarbital, the dynamic viscosity of the blood and the aggregative power of the blood cells were studied during the first 2 h after resuscitation by means of a capillary loop viscosimeter. An increase in viscosity was found both in the zone of small (1.82 dyn/cm2) and in the zone of large (10.94 dyn/cm2) shear stresses. The increase in the hematocrit index and in the aggregative power of the blood cells plays a definite role in the increase in viscosity.
