Early Predictors of Fluid Sequestration in Acute Pancreatitis: A Validation Study

Area of Science:

• Gastroenterology and Hepatology
• Critical Care Medicine
• Internal Medicine

Background:

• Acute pancreatitis (AP) is a serious condition characterized by inflammation of the pancreas.
• Fluid sequestration, a key complication, significantly impacts patient outcomes.
• Identifying early predictors of fluid sequestration is crucial for timely intervention.

Purpose of the Study:

• To externally validate previously identified predictors of increased fluid sequestration at 48 hours (FS⁴⁸) in patients with acute pancreatitis.
• To assess the association between these predictors and adverse outcomes in AP.

Main Methods:

• Retrospective analysis of 227 patients diagnosed with AP.
• Calculation of FS⁴⁸ as the difference between total fluid input and output within the first 48 hours.
• Linear regression analysis to evaluate associations between predictors (age, alcoholic etiology, hemoconcentration, hyperglycemia, SIRS) and outcomes (length of stay, fluid collections, necrosis, POF).

Main Results:

• Four of five previously identified predictors (younger age, alcoholic etiology, hemoconcentration, SIRS) independently predicted increased FS⁴⁸ (P < 0.05).
• Increased FS⁴⁸ was significantly associated with persistent SIRS and persistent organ failure (POF) (P < 0.01).
• A trend showed that the presence of four or more predictors correlated with higher rates of persistent SIRS and POF (P < 0.01).

Conclusions:

• The study successfully validated four key predictors of increased FS⁴⁸ in acute pancreatitis.
• The presence of multiple predictors (≥4) and significant fluid sequestration are linked to severe outcomes, including persistent SIRS and POF.
