Impact of early aggressive fluid resuscitation in acute pancreatitis

Acute pancreatitis management guidelines recommend early aggressive hydration to improve clinical outcomes. We aim to evaluate the influence of early fluid therapy (total intravenous fluids in the first 24 h [IVF/24hrs]) on clinical outcomes in patients with acute pancreatitis.

This was a retrospective chart review of all patients admitted for acute pancreatitis between July 2011 to December 2015. IVF/24hrs was categorized into 3 groups according to tertiles. Logistic regression was performed to evaluate predictors of persistent organ failure and in-hospital mortality.

A total of 310 patients were included: Conservative (IVF/24hrs < 2.8L, n = 102), Moderate (IVF/24hrs 2.8-4.475L, n = 105) and Aggressive (IVF/24hrs ≥ 4.475, n = 103). Most patients (80.6%) were African Americans, 91.3% had mild acute pancreatitis (BISAP score ≤ 2). The Aggressive IVF group had higher incidence of persistent organ failure (16.5% vs 4.9% and 7.6%, p = 0.013), and longer length of hospital stay (9.2 ± 10.7 vs 6.5 ± 7.3 and 6.8 ± 5.7 days, P = 0.032). However, IVF/24hr did not correlate with length of hospital stay (PCC 0.08, p = 0.174). On multivariate analysis, only organ failure at admission was an independent predictor of persistent organ failure (OR 16.1, p < 0.001). Persistent organ failure and local complications were found to be the only independent predictors in-hospital mortality (OR 27.6, p < 0.001 and OR 16.95, p = 0.001 respectively). There was no difference in clinical outcomes in African Americans compared to other races.

More aggressive early IVF therapy in a predominantly mild acute pancreatitis cohort, was not associated with improvement in persistent organ failure, length of hospital stay, or in-hospital mortality.
