Background: Third space fluid loss is one of the hallmarks of the pathophysiology of acute pancreatitis (AP) contributing to complications, including organ failure and death. We conducted a systematic review of literature to determine the ideal fluid resuscitation in the early management of AP, primarily comparing aggressive versus moderate intravenous fluid resuscitation (AIR vs MIR).
Methods: A systematic review of major reference databases was undertaken. Meta-analysis was performed using random-effects model. Bias was assessed using Cochrane risk of bias and ROBINS-I tools for randomized and non-randomised studies, respectively.
Results: Twenty studies were included in the analysis. Though there was no significant difference in mortality between AIR and MIR groups (8.3% versus 6.0%; p = 0.3), AIR cohort had significantly higher rates of organ failure (p = 0.009), including pulmonary (p = 0.02) and renal (p = 0.01) complications. Similarly, there was no difference in mortality between normal saline (NS) and Ringer's lactate (RL) (3.17% versus 3.01%; p = 0.23), though patients treated with NS had a significantly longer length of hospital stay (LOS) (p = 0.009).
Conclusions: Current evidence appears to support moderate intravenous resuscitation (level of evidence, low) with RL (level of evidence, moderate) in the early management of AP.
