Ranson Criteria (Acute Pancreatitis, Non-Gallstone)

Calculate the Ranson criteria to grade acute pancreatitis severity and estimate mortality (non-gallstone/classic variant). Five criteria at admission (age >55, WBC >16,000, glucose >200, AST >250, LDH >350) and six at 48 hours (hematocrit fall >10%, BUN rise >5 mg/dL, calcium <8, PaO₂ <60, base deficit >4, fluid sequestration >6 L); each = 1 point, total 0–11. Interpretation: 0-2 mild (~2% mortality), 3-4 moderate (~15%), 5-6 severe (~40%), ≥7 very severe (~100%). The gallstone variant uses different thresholds and is NOT included. Derived from Ranson et al. 1974. Not medical advice.
