Abstract: Sepsis is a lethal organ dysfunction caused by infection induced reaction maladjustment. Thrombocytopenia is not only a common complication of sepsis, but also closely related to the patient's prognosis. In the clinical treatment, it is important to identify the etiology and pathogenesis of thrombocytopenia associated with sepsis and choose appropriate methods to correct thrombocytopenia in time to improve the prognosis of patients. This article gives an introduction to the research status of the etiology, pathophysiological mechanism and molecular mechanism of sepsis-related thrombocytopenia.

Key words: sepsis, thrombocytopenia, pathogen, pathophysiological mechanisms, molecular mechanism
