[State of microcirculation following massive administration of homologous donor blood to dogs].

Homologous normovolemic donor blood exchange provoked a moderate slowing down of the blood flow in the microcirculation and intravascular aggregation of the red blood cells--moderate or severe. Acute phenomena of blood deposition in the mesenteric vessels with a simultaneous reduction of the perfusion level in the microvessels of the bulbar conjunctiva developed in 25% of cases. Acute microcirculatory disturbances were transitory in character.
