Mangled Extremity Severity Score (MESS) [11]
| Skeletal/soft tissue injury |
|
|
| Low energy injury (eg. simple bone fracture) - 1 point |
| Medium energy injury (eg. multiple bone fractures) - 2 points |
| High energy injury (eg. car accidents) - 3 points |
| Very high energy injury (eg. high speed trauma with severe contamination) - 4 points |
|
|
| Limb ischemia |
|
|
| Normal perfusion with reduces or even absent pulse - 1xpoint |
| Absent pulse,paresthesia, diminished capillary refill - 2points |
| Cool, paralyzed, insensate limb - 3xpoints |
|
|
| Shock |
|
|
| Systolic blood pressure > 90 mm Hg: 0 points |
| Hypotensive transiently: 1 point |
| Hypotensive persistent: 2 points |
