Historically, red blood cell transfusion was considered when the hemoglobin level fell below 100g/L or hematocrit fell below 30%. [3] [4] Because each unit of blood given carries risks, a trigger level lower than that, at 70 to 80g/L, is now usually used, as it has been shown to have better patient outcomes.
Autotransfusion is a process wherein a person receives their own blood for a transfusion, instead of banked allogenic (separate-donor) blood.There are two main kinds of autotransfusion: Blood can be autologously "pre-donated" (termed so despite "donation" not typically referring to giving to one's self) before a surgery, or alternatively, it can be collected during and after the surgery using ...
Blood products are typically transfused at 2.0 to 2.5 ml/kg per hour but can be reduced to 1.0 ml/kg per hour for individuals at increased risk for TACO. [16] Patients susceptible to volume overload (e.g., renal insufficiency or heart failure) may be pre-treated with a diuretic either during or immediately following transfusion to reduce the ...

While the incidence of hypovolemic shock from extracellular fluid loss is difficult to quantify, it is known that hemorrhagic shock is most commonly due to trauma. In one study, 62.2% of massive transfusions at a level 1 trauma center were due to traumatic injury. In this study, 75% of the blood products used were related to traumatic injury.
Intraoperative blood salvage (IOS), also known as cell salvage, is a specific type of autologous blood transfusion. Specifically IOS is a medical procedure involving recovering blood lost during surgery and re-infusing it into the patient. It is a major form of autotransfusion.
