This is a randomized controlled trial to compare viscoelastometric (VE) guided transfusion to standard practice transfusion in severe thermal injury burn excision on the utilization of blood products, effects on coagulation and inflammatory mediators, and how these strategies affect post resuscitation infections.

This is an open labeled study as the viscoelastometric (VE) guided transfusion will be based on the visible VE results. Subjects will be randomized to receive either the standard practice transfusion or VE guided transfusion. Blood samples, standard demographic information, and routine laboratory data will be collected on all subjects in the Burn ICU (BICU) enrolled in the study. VE analysis will be performed on ALL subjects immediately prior to the burn excision, and approximately every 40 minutes while the patient is in the operating room (OR) as well as on arrival to the BICU and every 8 hours depending on their need for ongoing transfusion for a maximum of 24 hours. As our intervention, only the VE based transfusion group will have access to the VE analysis at time of transfusion. The VE results will be used at the discretion of the treating physician based on the VE guided transfusion algorithm. Outcomes include the number and timing of blood products transfused from the time of randomization to 24 hours post randomization and the presence of any 30 day post-transfusion infections.

Inclusion Criteria:

• Burn patients admitted to Parkland Hospital with total burn surface area (TBSA) greater than 20%

Exclusion Criteria:

• Patients admitted to Parkland Hospital for reasons other than burns or for burns less than or equal to 20%
