Summary
The purpose of this study is to look at red blood cell (RBC) transfusions in trauma patients and evaluate for any differences between the age of the RBCs and how they were stored. The investigators will specifically look for the following differences between study groups:
1. the transfused red blood cells' ability to delivery oxygen to the tissues
2. differences in biochemical markers in subjects and units transfused, and
3. how the subject's internal organs are working and if they develop any infections
Eligibility Criteria
Inclusion Criteria
- Trauma Service with an Injury Severity Score > 4
- Require a blood (PRBC) transfusion
- Transfusion is not emergent
- Able to obtain consent from patient or appropriate 3rd party prior to 1st transfusion
Exclusion Criteria
- Inability to adhere to blood age randomization due to limitations of the blood bank inventory
- Bilateral hand injuries that prevent StO2 measurements
- Age 10 units in 24 hours) in last 3 months
- Hemodynamically unstable or need for transfusion in < 3 hours
