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%
