Episode notes
Revised Atlanta Classification Value
- Classic Ranson or APACHE scores have limited specificity and low positive predictive value in pancreatitis.
- The revised Atlanta classification is simpler and more practical for assessing severity and guiding management.
Avoid Trending Lipase
- Avoid trending lipase to assess disease severity or improvement.
- Clinical evaluation of organ function and patient status is far more valuable than lipase trends.
Fluid Choice and Rate
- Use lactated Ringer's solution preferentially for fluid resuscitation in acute pancreatitis.
- Give 5-10 mL/kg/hour early in the first 24-48 hours to prevent progression to necrotizing pancreatitis.
