What are the 11 Ranson criteria?

Admission (5): age > 55, WBC > 16,000, glucose > 200 mg/dL, LDH > 350 IU/L, AST > 250 IU/L. 48h (6): haematocrit drop > 10%, BUN rise > 5 mg/dL, calcium 4 mEq/L, fluid sequestration > 6 L.

How accurate are Ranson criteria?

Sensitivity ~65-70% for severe pancreatitis, specificity ~80%. Limited by 48h delay, inability to reassess, and gallstone-specific modified criteria. BISAP and APACHE II are simpler alternatives for ongoing monitoring.

Do Ranson criteria differ for gallstone pancreatitis?

Yes - modified Ranson for gallstone pancreatitis uses: age > 70, glucose > 220, LDH > 400, AST > 250 at admission; haematocrit fall > 10%, BUN rise > 2, calcium 5, fluid deficit > 4L at 48h.

Ranson Criteria for Pancreatitis Severity

Assess pancreatitis severity using Ranson criteria: 5 at admission + 6 at 48h. Score 0-2: mild (1% mortality); 3-4: moderate (15%); 5-6: severe (40%); >= 7: critical (nearly 100%).
