A 40-year-old male is admitted with severe acute pancreatitis. Which validated scoring system uses five clinical parameters measured at admission (Age > 55, WBC > 16,000, Blood Glucose > 11 mmol/L, Serum AST > 250 U/L, Serum LDH > 350 U/L) to assess the severity and mortality risk of acute pancreatitis?

Answer and explanation

Correct answer: B. Ranson Criteria

  1. Step 1: The Ranson Criteria assess acute pancreatitis severity using 5 initial parameters on admission and 6 parameters assessed at 48 hours.
  2. Step 2: A score >= 3 indicates severe pancreatitis with elevated risk of systemic complications and mortality.
Answer
Ranson Criteria.
Why not the others: 'APACHE II' is a complex physiological ICU score using 12 variables; 'Glasgow-Imrie' uses 8 parameters evaluated across the first 48 hours; 'BISAP' uses 5 variables within the first 24 hours (BUN, Impaired mental status, SIRS, Age, Pleural effusion).
