El-Menyar et al reported the FASILA score for a patient with abdominal trauma. This can help to identify a patient who may require massive blood transfusion. The authors are from Hamad General Hospital and Weill Cornell Medical College in Doha, Qatar.
FASILA = FAST (FA), Shock Index (SI), Serum lactate (LA)
Patient selection: abdominal trauma
Parameters:
(1) FAST
(2) shock index
(3) blood lactate concentration in mmol/L

total score =
= SUM(points for all 3 parameters)
Interpretation:
• minimum score: 0
• maximum score: 6
• The higher the score the more likely the need for massive transfusion.
