ACUTE PANCREATITIS RISK ACESSMENT

Ranson Criteria for Acute Pancreatitis

Admission Criteria

Age (>55 years) WBC (>16000) Glucose (>200 mg/dL) AST (>250 IU/L) LDH (>350 IU/L)

48-Hour Criteria

Calcium (<8 mg/dL) Hematocrit Fall (>10%) PaO₂ (<60 mmHg) BUN Increase (>5 mg/dL) Base Deficit (>4 mEq/L) Fluid Sequestration (>6 L)

Individual Score:

≥ 3 : Severe Acute Pancreatitis

< 3 : Severe Pancreatitis is unlikely, correlate clinically with your investigations

Total Score (Admission as well as 48 hour criteria) Mortality Prediction

Score Predicted Mortality

0 to 2 2% mortality

3 to 4 15% mortality

5 to 6 40% mortality

7 to 8 100% mortality

Score	Predicted Mortality
0 to 2	2% mortality
3 to 4	15% mortality
5 to 6	40% mortality
7 to 8	100% mortality

BISAP Score Mortality Prediction

BISAP Score Mortality Risk

0 to 2 Points Lower mortality less than 2 percent

3 to 5 Points Higher mortality greater than 15 percent

Patients with a score of 3 or greater have a significantly increasing risk of mortality.

BISAP Score	Mortality Risk
0 to 2 Points	Lower mortality less than 2 percent
3 to 5 Points	Higher mortality greater than 15 percent
