[Coagulation factors in human born blisters (author's transl)].

Following clotting factor assays were performed on the fluid of burn blisters of 11 patients with severe burns: Fibrinogen levels, Factor II, V, X and XIII, thrombin time, fibrin split products, plasminogen, antithrombin III, IgA, IgM, IgG, ethanol gelation test and total proteins. The results showed, that a quantity of Factor II, X and XIII, antithrombin III, plasminogen and IgG had left the circulation. On the contrary we found only small concentrations of Factor V, fibrinogen, IgM and IgA in the fluid of burn blisters. This distribution suggested that the losses of plasma proteins into the burn blisters were correlated to their concentration and their molecular weight. The decrease of plasma coagulation proteins during the first days after severe burns was probably partly due to losses through the walls of the vessels, because of the increased capillary permeability.
