Coagulation system and platelets are fully activated in uncomplicated sepsis

Abstract

Coagulation system and platelets are strongly activated in sepsis. In this stage, only factor XII is decreased. In contrast, in severe sepsis and mainly in septic shock, most of the coagulation factors are depleted, PTL is decreased, and global coagulation tests are prolonged, indicating exhaustion of hemostasis. Finally, Gram-positive, Gram-negative, and other microorganisms produce identical impairment of coagulation.
