Abstract: Disseminated intravascular coagulation (DIC) triggered by sepsis is a major challenge in the emergency and critical care of severely ill patients. The inflammasome is an essential component of the human immune system, and its activation can mediate pyroptosis and then release interleukin (IL)-1β and IL-18, which further activates platelets and the coagulation system and exacerbates inflammatory responses and coagulation processes, thus creating great uncertainty for the treatment and prognosis of sepsis. This article aims to review the correlation between the inflammasome and pyroptosis, as well as their impact on coagulation function, in hope of providing new insights for the clinical treatment of DIC.
