What is the management plan for acute pancreatitis?

Management of Acute Pancreatitis

The management of acute pancreatitis should include early fluid resuscitation with moderate amounts of Lactated Ringer's solution, early oral feeding within 24 hours, pain control, and selective use of ERCP for gallstone pancreatitis with cholangitis. 1

Initial Assessment and Classification

• Determine severity using objective criteria:

  • Mild pancreatitis (80% of cases): Self-limiting course with <5% mortality 2
  • Severe pancreatitis (20% of cases): Associated with 95% of deaths 2
  • Use APACHE II score >8 to predict severe disease 1

• Identify etiology (should be determined in 75-80% of cases):

  • Gallstones
  • Alcohol
  • Hypertriglyceridemia
  • Medications
  • Idiopathic (should not exceed 20-25% of cases) 2

Management Based on Severity

Mild Acute Pancreatitis

1. Fluid Resuscitation

   • Use moderate fluid resuscitation with Lactated Ringer's solution rather than Normal Saline 1, 3
   • Initial rate of 5-10 ml/kg/hr with crystalloids 1
   • Avoid aggressive hydration as it increases risk of fluid overload without improving outcomes 4

2. Pain Management

   • Provide adequate analgesia with opioids as needed 1
   • For neuropathic pain components, consider gabapentin, pregabalin, nortriptyline, or duloxetine 1

3. Nutrition

   • Begin early oral feeding within 24 hours of admission 1
   • This approach is associated with 2.5-fold lower risk of interventions for pancreatic necrosis 1
   • No need for prolonged fasting

4. Monitoring

   • Basic monitoring of temperature, pulse, blood pressure, and urine output 2
   • Peripheral IV line for fluids
   • Nasogastric tube if needed

5. Antibiotics

   • Do not administer antibiotics routinely in mild cases 2, 1
   • Use only when specific infections occur (chest, urine, bile, or cannula related) 2

6. Imaging

   • Routine CT scanning is unnecessary unless there are clinical signs of deterioration 2
   • Obtain right upper quadrant ultrasound to assess for gallstones 1

Severe Acute Pancreatitis

1. Location of Care

   • Manage in ICU or HDU setting with full monitoring and systems support 2, 1

2. Monitoring and Support

   • Place central venous line (for fluid administration and CVP monitoring)
   • Insert urinary catheter and nasogastric tube 2
   • Consider Swan-Ganz catheter if cardiocirculatory compromise exists 2
   • Regular arterial blood gas analysis
   • Hourly monitoring of vital signs, oxygen saturation, urine output, and temperature 2

3. Fluid Resuscitation

   • Moderate fluid resuscitation with Lactated Ringer's solution 1, 4
   • Avoid aggressive hydration as it increases risk of fluid overload (20.5% vs 6.3%) 4

4. Nutrition

   • Start early enteral feeding within 24 hours if possible 1
   • If oral feeding not tolerated, use enteral nutrition via tube feeding (either nasogastric or nasoenteral) 1
   • Enteral nutrition reduces risk of infected peripancreatic necrosis (OR 0.28), single organ failure (OR 0.25), and multiple organ failure (OR 0.41) 1

5. Antibiotics

   • Consider prophylactic antibiotics in severe acute pancreatitis 1
   • IV cefuroxime is recommended when used 1

6. CT Scanning

   • Perform contrast-enhanced CT scan 72-96 hours after symptom onset 1
   • Helps evaluate severity and detect complications

Management of Gallstone Pancreatitis

1. ERCP Indications

   • Urgent ERCP and sphincterotomy for:
     • Severe gallstone pancreatitis with persistent symptoms beyond 48 hours 2
     • Acute cholangitis 1
     • Persistent biliary obstruction 1
   • Always perform ERCP under antibiotic cover 2

2. Cholecystectomy Timing

   • Mild cases: Perform within 2-4 weeks, ideally during same hospitalization 2, 1
   • Severe cases: Delay until inflammatory process has subsided 2, 1
   • Cases with local complications: After treatment or resolution of complications 1

Complications Management

• Local Complications (pseudocyst, necrosis):

  • Manage infected necrosis with a step-up approach 5
  • Delay interventions for at least 4 weeks if possible to allow for walling-off of necrosis 5

• Organ Failure:

  • Provide supportive care with close monitoring
  • Evaluate using established criteria for cardiovascular, respiratory, and renal systems 1

Special Considerations

• Alcoholic Pancreatitis:

  • Provide brief alcohol intervention during admission 1

• Hereditary Pancreatitis:

  • Refer to specialist centers for expert assessment and genetic counseling 1

Common Pitfalls to Avoid

1. Aggressive fluid resuscitation (increases risk of fluid overload without improving outcomes) 4
2. Routine use of prophylactic antibiotics in mild cases 2, 1
3. Prolonged fasting (delays recovery and increases complications) 1
4. Delaying cholecystectomy in mild gallstone pancreatitis 2, 1
5. Performing ERCP in all cases of gallstone pancreatitis (should be selective) 2
6. Using Normal Saline instead of Lactated Ringer's solution for fluid resuscitation 3
