Hypercoagulability is common in septic shock patients with thrombocytopenia. This hypercoagulable state, identified by thromboelastography (TEG), is linked to lower mortality rates.
Area of Science:
- Critical Care Medicine
- Hematology
- Pathophysiology
Background:
- Sepsis often presents with thrombocytopenia, yet hypercoagulability can coexist.
- Limited data exists on the prevalence and impact of hypercoagulability in sepsis-induced thrombocytopenia.
Purpose of the Study:
- To determine the prevalence of hypercoagulability in septic shock patients with thrombocytopenia.
- To investigate the association between hypercoagulability and clinical outcomes, including mortality.
Main Methods:
- Prospective study of 889 septic shock patients in the emergency department.
- Thromboelastography (TEG) used to assess coagulation status; hypercoagulability defined as Coagulation Index (CI) > 3.
- Thrombocytopenia defined as a platelet count < 150,000/µl.
Main Results:
- 53.2% of patients had thrombocytopenia.
- 18.0% of patients exhibited hypercoagulability via TEG.
- Hypercoagulable patients had higher fibrinogen levels and significantly lower 28-day mortality (7.1%) compared to normal or hypocoagulable groups.
Conclusions:
- Hypercoagulability is a frequent finding in septic shock patients with thrombocytopenia.
- TEG is a valuable tool for rapid assessment of coagulation status and risk stratification.
- Hypercoagulable TEG was independently associated with decreased mortality.

Two factors primarily cause thromboembolic conditions.
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,...
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...
Coagulation
During the coagulation phase, clotting factors, or procoagulants, play a vital role in initiating and progressing the coagulation cascade. This cascade is a series of reactions...
