Management of Acute Pancreatitis
Lactated Ringer's solution should be used as first-line fluid therapy for acute pancreatitis, with goal-directed resuscitation targeting urine output >0.5 mL/kg/h and arterial saturation >95%. 1
Initial Assessment and Resuscitation
Fluid Resuscitation
- Use Lactated Ringer's solution as the preferred crystalloid 1, 2
- Target moderate fluid resuscitation with the following goals:
- Urine output >0.5 mL/kg/h
- Arterial saturation >95%
- Monitor hematocrit, BUN, creatinine, and lactate 1
Monitoring
- All cases of severe acute pancreatitis should be managed in HDU or ICU with full monitoring 4
- Minimum monitoring requirements:
- For cardiocirculatory compromise, consider Swan-Ganz catheter for advanced hemodynamic monitoring 4
Nutritional Support
- Begin early oral feeding within 24 hours as tolerated 1
- If oral feeding not possible, initiate enteral nutrition within 24-72 hours via nasogastric or nasojejunal routes 1
Pain Management
- Implement multimodal analgesia approach
- Use morphine or hydromorphone as first-line opioid analgesics
- Consider epidural analgesia for severe cases requiring high doses of opioids 1
Management of Gallstone Pancreatitis
ERCP Indications
- Urgent ERCP (within 24 hours) is indicated for:
- Always perform ERCP under antibiotic cover 4
Cholecystectomy Timing
- For mild gallstone pancreatitis: perform cholecystectomy during the same hospital admission
- Significantly reduces mortality and gallstone-related complications
- Reduces readmission for recurrent pancreatitis 1
- If same-admission cholecystectomy not possible, schedule within two weeks 1
Antibiotic Management
- Do not use prophylactic antibiotics for sterile necrosis
- Use antibiotics only for documented infections
- Maximum duration of 14 days for infected necrosis
- Use broad-spectrum antibiotics covering gram-negative, gram-positive, and anaerobic organisms
- Imipenem shows good penetration into pancreatic tissue 1
Imaging
- Perform contrast-enhanced CT scan for severity assessment in patients with predicted severe disease
- Avoid routine follow-up CT scans unless clinical status deteriorates 1
Additional Interventions
- Provide supplemental oxygen to maintain arterial saturation >95% 1
- Implement strict glucose control with insulin therapy for hyperglycemia 1
- For alcoholic pancreatitis, provide brief alcohol intervention during admission 1
Pitfalls and Caveats
- Avoid aggressive fluid resuscitation in patients with predicted severe disease as it might be futile and potentially harmful 5
- Maintain strict asepsis when placing invasive monitoring equipment (central lines) to prevent secondary infection in pancreatic necrosis 4
- Do not use specific drug therapies (antiproteases, antisecretory agents) as they have not shown benefit in large randomized studies 1
- Early elevated hematocrit, blood urea nitrogen, or creatinine should prompt more intensive early resuscitation measures 6
