What is Imrie score?

The Glasgow Imrie score is a modification of the Ranson’s criteria for acute pancreatitis. It was originally composed of 9 factors however this was subsequently reduced to 8 components due to a superior predictive value.

How is Ranson Criteria calculated?

Ranson’s Criteria for Pancreatitis Mortality

1. WBC > 16k. No. Yes. +1.
2. Age > 55. No. Yes. +1.
3. Glucose >200 mg/dL (>10 mmol/L) No. Yes. +1.
4. AST > 250. No. Yes. +1.
5. LDH > 350. No. Yes. +1.
6. Hct drop >10% from admission. No. Yes. +1.
7. BUN increase >5 mg/dL (>1.79 mmol/L) from admission. No. Yes. +1.
8. Ca <8 mg/dL (<2 mmol/L) within 48 hours. No. Yes. +1.

Why are Glasgow Imrie criteria similar to Ranson’s?

Using a scoring system may help standardize treatment and allow for targeting patients in greatest danger. The Glasgow-Imrie Criteria are comparable to the Ranson’s criteria, but both have a disadvantage of requiring a 48 hours delay before they can be appropriately applied.

What are the limitations of the Ranson criteria?

Ranson et al. also showed a Ranson score greater than 2 had a sensitivity of 84.2% and a specificity of 89.8%. The second limitation is that the score and severity of acute pancreatitis cannot be determined until 48 hours have passed since admission. This limits its utility in time-sensitive situations like the emergency department.

What is the purpose of the Ranson score?

Ransons criteria are primarily used in the inpatient setting. It basically is used to determine role of operative treatment, weighted toward multi-organ failure, SIRS, and vascularleak. A Ranson score of 0 or 1 predicts that complications will not develop and that mortality will be negligible.

How does Ranson score work for acute pancreatitis?

Ranson score interpretation Within the model, each positive occurrence of the criteria involved is awarded a point and then the sum of the points defines the acute pancreatitis mortality risk.
