[Experimental protracted shock. II. Blood coagulation and histological changes].

Twenty mongrel dogs are subjected to a standardized traumatic hemorrhagic shock. After reinfusion of the dogs' own blood the animals are continuously observed for the 72 hr. Deterioration of general hemodynamics and activation of intravascular coagulation is more pronounced in the nonsurviving animals. Correspondingly, histologic alterations particularly of the liver and intestine are more marked in the nonsurvivors. Increase of partial thromboplastin time and long-lasting increase of the prothrombin time (Quick) appear to be early signs of a fatal prognosis.
