Nonaggressive Versus Aggressive Intravenous Fluid Therapy in Acute Pancreatitis With More Than 24 Hours From Disease Onset

OBJECTIVE: This study aimed to compare a "nonaggressive" hydration versus an "aggressive" hydration using Hartmann's solution in patients with acute pancreatitis (AP) with more than 24 hours from disease onset. METHODS: We included 88 patients with AP with more than 24 hours from disease onset, and were randomized into 2 groups. Group I (n = 45) received a nonaggressive hydration (Hartmann's solution at 1.5 mL kg h for the first 24 hours and 30 mL kg during the next 24 hours), and group II (n = 43) received an aggressive hydration (bolus of Hartmann's solution 20 mL kg, followed by an infusion of 3 mL kg h for the first 24 hours and then 30 mL kg for the next 24 hours). RESULTS: The mean volume of fluid administered was greater in group II (P < 0.001). We did not find differences when comparing both groups in reference to persistent systemic inflammatory response syndrome (P = 0.528), pancreatic necrosis (P = 0.710), respiratory complications (P = 0.999), acute kidney injury (P = 0.714), or length of hospital stay (P = 0.892). CONCLUSIONS: Our study suggests that the clinical evolution of patients with AP with more than 24 hours from disease onset is similar using an aggressive or nonaggressive hydration.
