Ranson criteria


The Ranson criteria form a clinical prediction rule for predicting the prognosis and mortality risk of acute pancreatitis. They were introduced in 1974 by the English-American Pancreatic Expert and Surgeon, Dr. John Ranson.

Usage

This is for causes other than gall stones.
At admission:
  1. Age in years > 55 years
  2. WBC count > 16000 cells/mm3
  3. Blood glucose > 11.11 mmol/L
  4. Serum AST > 250 IU/L
  5. Serum LDH > 350 IU/L
Within 48 hours:
  1. Serum calcium < 2.0 mmol/L
  2. Hematocrit fall > 10%
  3. Oxygen
  4. BUN increased by 1.8 or more mmol/L after IV fluid hydration
  5. Base deficit > 4 mEq/L
  6. Sequestration of fluids > 6 L
For acute pancreatitis secondary to gall stones.
At admission:
  1. Glucose > 220mg/dl
  2. Age > 70 years
  3. LDH > 400IU/L
  4. AST > 250IU/L
  5. WBCs > 18000/ mm3
Within 48 hours:
  1. S. Calcium < 8mg%
  2. Hematocrit >10%
  3. Base deficit > 4 mEq/L
  4. BUN > 2mg%
  5. Sequestrated fluid > 6L
Score of 3 or more indicates severe acute pancreatitis.
The mnemonic GALAW & CHOBBS can be used to remember this criteria. Stands for Glucose, Age, LDH, AST and WBC; Calcium, Hematocrit, Oxygen, BUN, Base, Sequestration.

Alternatives

Alternatively, pancreatitis severity can be assessed by any of the following:
