Pearls and Pitfalls
Blood transfusion is substantially overutilized and has significant associated risk, including: transfusion reactions, transmission of blood borne pathogens, and immune suppression.
The accepted transfusion “trigger” in euvolemic patients is 7 gm/dl for healthy individuals and 8–9 gm/dl for patients with co-morbidities associated with decreased cardiopulmonary reserve.
Blood transfusion is an independent predictor of MOF, SIRS, increased infection, and mortality in patients with severe injuries and undergoing complex surgical procedures.
Transfusion of only the amount of blood that maximizes immediate survival and minimizes late inflammatory complications is the goal of resuscitation.
Trauma patients and other patients in hemorrhagic shock should be transfused based upon blood pressure, pulse, and other measurements of decreased perfusion rather than relying upon laboratory values.
“The triad of death” including bleeding, hypothermia, and acidosis, leads to the...
