Sequential Coagulation Studies in Purpura Fulminans

Abstract
CORRECTION of abnormally low concentration of plasma components is usually attempted by replacement therapy. However, evidence from studies of purpura fulminans in man1 , 2 and from studies of the Shwartzman reaction in rabbits3 , 4 suggests that the coagulation deficiencies associated with these pathologically similar conditions5 are corrected more by anticoagulant therapy than by replacement therapy. This seemingly paradoxical treatment has developed with the concept that the deficiencies observed are due to intravascular coagulation.6 Indeed, these deficiencies are simitar to those existing in serum after in vitro coagulation of blood – for example, deficiencies of platelets and factors I (fibrinogen), II (prothrombin), V . . .
