Summary
Viscoelastic testing, including rotational thromboelastometry (ROTEM) and thromboelastography (TEG), offers a global assessment of blood clotting in trauma patients. This review covers the history, technical details, and clinical applications of these evolving diagnostic tools for managing traumatic injury.
Area of Science:
- Hematology
- Trauma Surgery
- Diagnostic Technologies
Background:
- Viscoelastic testing is a well-established yet advancing technology in trauma care.
- Conventional coagulation tests offer limited, specific insights into hemostasis.
- Viscoelastic methods provide a comprehensive, global perspective on blood clot formation and dynamics.
Purpose of the Study:
- To review the historical development of viscoelastic testing.
- To detail the technical principles of rotational thromboelastometry (ROTEM) and thromboelastography (TEG).
- To summarize current clinical data regarding the use of ROTEM and TEG in managing traumatic injuries.
Main Methods:
- Literature review of historical and current research on viscoelastic testing.
- Analysis of technical specifications for ROTEM and TEG devices.
- Synthesis of clinical studies evaluating ROTEM and TEG in trauma patient management.
Main Results:
- Viscoelastic testing provides a holistic view of the coagulation cascade, unlike segmented conventional assays.
- ROTEM and TEG are the primary modalities currently employed for viscoelastic assessment.
- Clinical data supports the utility of these tests in guiding transfusion strategies and monitoring hemostasis in trauma.
Conclusions:
- Viscoelastic testing, encompassing ROTEM and TEG, is crucial for comprehensive coagulation assessment in trauma.
- Understanding the technical aspects and clinical applications of these tests is vital for effective patient management.

Introduction to Hemostasis
Hemostasis is a complex physiological process that prevents excessive bleeding when a blood vessel is injured. It's crucial for maintaining the integrity of the circulatory system, as it ensures that our blood remains fluid while still within the vascular network and yet clots to prevent blood loss upon vessel injury.
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
Blood clotting or coagulation involves extrinsic and intrinsic pathways, which ultimately merge into the common pathway, forming a fibrin clot.
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...

Formation of the Platelet Plug
The platelet phase, the second stage of hemostasis, commences around 15-20 seconds after an injury. It follows and overlaps with the vascular phase, during which blood vessels constrict to minimize blood loss.
As the injured blood vessel contracts, endothelial cells undergo contraction, revealing collagen fibers in the basement membrane and underlying connective tissue. Furthermore, the plasma membrane of endothelial cells becomes adhesive, preparing the site for platelet adhesion. Platelets...

Vascular Spasm
The vascular phase, also known as vasospasm, is the initial stage of hemostasis, crucial for preventing excessive bleeding when a blood vessel is injured. After a vessel is cut, nerves in the damaged area trigger pain and other sensory impulses. Simultaneously, the smooth muscles in the vessel wall contract, resulting in a vascular spasm. This contraction reduces the vessel's diameter at the injury site, slowing or stopping blood loss through the vessel wall. Vascular spasms typically last for...
