Curated insights • How it Works • Practical Pearls • Evidence Base
5 criteria are assessed at admission; 6 additional criteria are assessed at 48h. The full score cannot be calculated at presentation — use APACHE II or Bedside Index of Severity in Acute Pancreatitis (BISAP) for earlier risk stratification.
Lactated Ringer's solution is preferred over normal saline in acute pancreatitis (reduces SIRS response). Target urine output ≥ 0.5 ml/kg/h. Aggressive hydration in first 48h (250–500 ml/h unless cardiac contraindication).
NPO is no longer standard. Early enteral nutrition (nasoenteral at 24–48h) improves outcomes vs parenteral nutrition. Reserve TPN for those with severe ileus or inaccessible enteral access.
ERCP is indicated in gallstone pancreatitis ONLY if concurrent cholangitis or persistent biliary obstruction. Routine early ERCP does not improve outcomes in predicted severe pancreatitis.
Prognostic signs and the role of operative management in acute pancreatitis.
A surgeon at New York University who published the original 11-criterion scoring system in 1974. Ranson's criteria remained the dominant severity assessment tool for acute pancreatitis for over three decades. The APACHE II and BISAP scores now complement or replace Ranson's for early triage, but the Ranson criteria remain widely taught and embedded in clinical guidelines globally.
