Title: A Randomized Clinical Trial of Restrictive vs. Traditional Blood Transfusion Practices in Burn Patients
Brief Summary: The purpose of this study is to find out if burn injured patients do better receiving fewer blood transfusions than what is traditionally given. We traditionally provide blood transfusions to maintain a hemoglobin level, which is an indicator of the level of red blood cells that carry oxygen in your body, to above 10 g/dl (g/dl stands for grams per deciliter and is the standard measurement used to indicate the level of red blood cells in your blood). However, a preliminary study indicated that maintaining the hemoglobin level to above 7-8 g/dl with less blood transfusion, as compared to a hemoglobin level of 10 g/dl and above, would reduce the occurrence of blood infection, duration on the respirator and length of hospital stay, yet would achieve similar survival in both groups.

* Receipt of red cell transfusion within 7 days of randomization
* Prior severe transfusion reaction
* Pregnancy
* Imminent death
* Decision to provide limited care
* Age \<21
