Point-of-care Testing of Coagulation in Intensive Care Unit: Role of Thromboelastography

Area of Science:

• Critical care medicine
• Hematology
• Point-of-care diagnostics

Background:

• Coagulation disorders are common and serious in intensive care unit (ICU) patients.
• Traditional coagulation tests have limitations in speed and comprehensiveness for critically ill patients.
• Effective management of hemostasis is crucial for patient outcomes.

Purpose of the Study:

• To review the role and utility of point-of-care testing (POCT) for coagulation in the ICU.
• To highlight the application of rotational thromboelastography (ROTEM) or thromboelastography (TEG) in managing coagulation abnormalities.
• To discuss the benefits of rapid, viscoelastic hemostatic assays in critical care.

Main Methods:

• Review of existing literature on thromboelastography (TEG) and rotational thromboelastography (ROTEM) in intensive care settings.
• Discussion of the principles and interpretation of thromboelastography-based assays.
• Analysis of clinical scenarios where TEG/ROTEM aids in diagnosis and treatment.

Main Results:

• Thromboelastography provides a comprehensive assessment of clot formation, stability, and lysis within minutes.
• POCT of coagulation facilitates rapid, data-driven therapeutic decisions for bleeding or thrombosis.
• Studies show improved outcomes and reduced blood product usage with goal-directed therapy guided by TEG/ROTEM.

Conclusions:

• Point-of-care coagulation testing, particularly thromboelastography, is a valuable tool in the ICU.
• It enables personalized and effective management of hemostatic disturbances.
• Widespread adoption can optimize patient care and resource utilization in critical care.
