From the Guidelines
The recommended approach for fluid resuscitation in acute pancreatitis is non-aggressive intravenous hydration, as aggressive hydration protocols have been shown to increase mortality risk and fluid-related complications in both severe and non-severe acute pancreatitis 1.
Key Considerations
- The goal of fluid resuscitation is to maintain adequate organ perfusion while avoiding fluid overload.
- Isotonic crystalloids, such as lactated Ringer's solution or normal saline, are recommended for fluid resuscitation.
- Fluid requirements should be individualized based on the patient's age, comorbidities, and severity of pancreatitis.
- Regular monitoring of vital signs, urine output, blood urea nitrogen, and hematocrit is essential to guide ongoing fluid therapy.
Evidence-Based Recommendations
- A systematic review and meta-analysis of 9 RCTs found that aggressive intravenous hydration protocols increased the mortality risk by 2.45-fold in severe acute pancreatitis and increased fluid-related complications by 2.22-3.25 times in both severe and non-severe acute pancreatitis 1.
- The American Gastroenterological Association institute guideline on initial management of acute pancreatitis recommends goal-directed fluid resuscitation, but notes that the optimal fluid therapy practice in acute pancreatitis is still uncertain and requires further research 1.
Clinical Implications
- Non-aggressive intravenous hydration protocols should be considered for fluid resuscitation in acute pancreatitis to minimize the risk of fluid-related complications and mortality.
- Clinicians should carefully monitor patients' fluid status and adjust the infusion rate based on clinical response to avoid fluid overload and ensure adequate organ perfusion.
- Further research is needed to determine the optimal fluid therapy strategy for acute pancreatitis, including the ideal infusion rate and type of fluid to use 1.
From the Research
Fluid Resuscitation in Acute Pancreatitis
- The recommended approach for fluid resuscitation in acute pancreatitis involves aggressive intravenous fluid resuscitation, which is a cornerstone of management for these patients 2.
- The optimal rate, type, and goal of resuscitation remain unclear, but crystalloids are currently recommended for management 2.
- Lactated Ringer's (LR) solution is a buffered crystalloid that may have advantages over normal saline (NS) in acute pancreatitis, with studies suggesting reduced 1-year mortality and systemic inflammation with LR 3, 4, 5.
Choice of Fluid
- Lactated Ringer's solution has been shown to be superior to normal saline in reducing systemic inflammation and 1-year mortality in patients with acute pancreatitis 3, 5.
- However, the difference in outcomes between LR and NS may not be significant in all cases, such as in patients with mild acute pancreatitis 4.
Goal-Directed Fluid Resuscitation
- Goal-directed fluid resuscitation protocols aim to optimize fluid administration based on patient response, but the optimal end points of fluid resuscitation remain unclear 2, 6.
- The WATERFALL trial is an ongoing study comparing aggressive vs. non-aggressive goal-directed fluid resuscitation in acute pancreatitis, with results expected to provide further guidance on optimal fluid resuscitation strategies 6.
