Treatment of Acute Pancreatitis
Moderate fluid resuscitation rather than aggressive hydration is the recommended approach for acute pancreatitis treatment, as aggressive hydration increases mortality risk in severe cases and fluid-related complications in all cases. 1
Initial Management
Fluid Resuscitation
- Begin with Lactated Ringer's solution (preferred over normal saline) 1:
- Initial bolus of 10 ml/kg in case of hypovolemia
- Follow with 1.5 ml/kg/hour maintenance rate
- Adjust based on clinical parameters (heart rate, blood pressure, urine output) and laboratory markers (hematocrit, BUN, creatinine)
- Reassess fluid status every 6-8 hours
Caution: Avoid aggressive fluid resuscitation as recent evidence shows it increases mortality compared to moderate fluid replacement 2. Watch for signs of volume overload including rapid weight gain, ascites, and jugular vein engorgement.
Pain Management
- Implement a multimodal approach to analgesia 1:
- First-line: Morphine or hydromorphone (Dilaudid)
- For severe cases: Consider epidural analgesia
- For persistent pain unresponsive to conventional analgesia: EUS-guided celiac plexus block
Nutritional Support
- Initiate early enteral nutrition within 24-72 hours via nasogastric or nasojejunal tube 1
- Dietary recommendations:
- Mild pancreatitis: Diet rich in carbohydrates, moderate in protein, moderate in fat
- Severe pancreatitis: Enteral route preferred over parenteral nutrition
- Target approximately 60 grams of protein per day
Management of Complications
Infected Necrosis
- Use a stepped approach starting with percutaneous drainage 1
- When antibiotics are indicated, use broad-spectrum coverage for gram-negative, gram-positive, and anaerobic organisms
Biliary Pancreatitis
- For cases with acute cholangitis or biliary stasis, consider early endoscopic retrograde cholangiopancreatography with or without endoscopic sphincterotomy (ERCP/ES) 3
Monitoring and Follow-up
- Monitor for organ failure and infectious complications, especially in severe cases
- Regular follow-up every 6-12 months to evaluate:
- Pain control
- Nutritional status
- Development of complications
- Quality of life 1
Special Considerations
For severe acute pancreatitis (SAP), consider:
- Referral to specialized centers experienced in SAP management
- Intensive care for preventing organ failures and infectious complications
- Continuous hemodiafiltration (CHDF) and continuous regional arterial infusion (CRAI) of protease inhibitor and/or antibiotics may be beneficial in early stages 3
For suspected infectious complications:
Important: The latest evidence strongly favors moderate over aggressive fluid resuscitation, contradicting some older practices. A 2024 meta-analysis of 6 RCTs showed aggressive fluid resuscitation increased mortality risk (RR 2.40) compared to moderate fluid replacement 2.
