Ranson's Criteria


Ranson’s criteria are used as a tool to calculate the severity of acute pancreatitis.

Yes = 1 point. No = 0 points.

On admission
Age > 55 yrs
WCC > 16,000
LDH > 600 U/I
AST > 120 U/I
Glucose > 10 mmol/l

Within 48 hours
Haematocrit fall > 10%
Urea rise > 0.9 mmol/l
Calcium < 2 mmol/l
pO2 < 60mmHg
Base deficit > 4
Fluid sequestration > 6 l

The predicted mortality
< 3  =  1%
3-4  =  15%
5-6  =  40%
> 6  =  100%
