The effect of thermal injury on hemodynamic, respiratory, and hematologic variables in relation to complement
Abstract:
The effects of thermal injury on circulation, respiration, and complement activity was studied in dogs. An aggregation of platelets in the blood and trapping in the lung were observed following burn injury. Leukopenia appeared first, then leukocytosis. Hemolysis of red cells corresponding to a destruction of about 30% of the erythrocytes was observed. A blood pressure decrease and a tracheal insufflation pressure increase followed thermal injury. Blood gas and lactate changes like those seen during a low perfusion state were recorded, but signs of impaired oxygenation of arterial blood were also observed. A possible mechanism by which denatured proteins might initiate some of the symptoms seen after thermal injury is suggested and its relation to complement activation is evaluated.

Introduction to Hemostasis
The three phases of hemostasis involve many clotting factors present in plasma and several substances released by platelets and injured tissue cells. It is a fast, localized, and...
Extrinsic and Intrinsic Pathways of Hemostasis
The Extrinsic Pathway
The extrinsic pathway of coagulation is typically initiated by tissue damage that exposes blood to tissue factor (TF), a protein released by the damaged tissue cells outside the blood vessels—this interaction with TF triggers biochemical reactions involving specific clotting factors. The key player here is Factor VII, which forms a...
