Abstract
Viscoelastic hemostatic assays (VHAs) have become a valuable tool in guiding transfusion therapy, particularly in trauma care. While various forms of VHA exist, all provide a quantitative assessment of clot kinetics, strength, and dissolution. Studies have demonstrated that VHA can reduce both mortality and utilization of blood products in the general population. Interpreting VHA results requires consideration of specific patient factors, such as age and altered physiological properties as in pregnancy and the process of aging. Further research is needed to establish accurate reference ranges for these specific populations. This review article provides a comprehensive overview of the technical aspects of VHA as well as their clinical uses in trauma resuscitation.
