Markers of Blood Loss
¡  Blood loss
¡  Base deficit
¡  Hypotension
¡  Coagulopathy
¡  Number of Units of blood transfused
Study included 169 patients receiving at least 1 unit PRBC /24
Defined Massive Transfusion as 3 units PRBC/1 hr.
1. Coined phrase Critical Administration Threshold
2. Threshold chosen based on logistic regression
MT designation identified only 33% of deaths
CAT designation identified 75% of deaths
MT patients the Hazard ratio was 1.82

Massive Transfusion Protocol
¡  Most hemorrhagic death occur early
¡  MT protocol that ensures rapid defined ratio
blood delivered is important
¡  Identification of these patients that need a MT
¡  Control source of bleeding
¡  Initiate a MT protocol
¡  MT protocol Is associated with decreased
mortality from hemorrhagic shock when utilized in
a 1:1:1 vs. 1:1:2 ratio without increase in
complications
