Massive Transfusion Protocols- Saving Lives 1:1:1 units at a Time Michael White, MD, FACS Detroit Receiving Hospital Hemorrhage accounts for 50% deaths in first 24 hrs Hemorrhage accounts for 80% of deaths in operating room Sihler and Napolitano: Chest 2009;136:1654-1667 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 Identifying Patients that need massive transfusion Assessment of Blood Consumption (ABC) Score Correctly Classified= 84-87% PPV=55% NPV=97% ACS TQIP: Massive Transfusion in Trauma ¡ ABC Score of two or more ¡ Persistent hemodynamic instability ¡ Active bleeding requiring operation or angioembolization ¡ Blood transfusion in the trauma bay Inclusion Criteria 1. > 16 yrs 2. > 1 unit PRBC in 1st 6 hrs 3.
