Management of Severe Pancreatitis
The management of severe pancreatitis requires aggressive fluid resuscitation with Lactated Ringer's solution, early enteral nutrition, appropriate pain control, and a step-up approach to interventions for complications, with surgical interventions delayed when possible to reduce mortality. 1
Initial Resuscitation and Monitoring
Fluid Resuscitation:
- Use Lactated Ringer's solution at 5-10 ml/kg/h with an initial 10 ml/kg bolus for hypovolemic patients 1
- Lactated Ringer's is superior to normal saline, reducing severity, mortality, need for intensive care, and both systemic and local complications 2
- Reassess fluid requirements at 12,24,48, and 72 hours based on clinical response 1
- Monitor for fluid overload as aggressive resuscitation can lead to complications 3
Oxygenation:
- Provide supplemental oxygen to maintain arterial saturation >95% 1
- Implement continuous oxygen saturation monitoring 1
- Mechanical ventilation must be instituted if oxygen therapy becomes ineffective in correcting tachypnea and dyspnea 4
- Use invasive ventilation when bronchial secretion clearance becomes ineffective or the patient is tiring 4
Nutritional Support
- Begin oral feeding within 24 hours as tolerated 1
- If oral feeding is not possible, initiate enteral nutrition via nasogastric or nasojejunal routes within 24-72 hours 1
- Early enteral nutrition is preferred over parenteral nutrition unless ileus persists >5 days 1
- Diet should be rich in carbohydrates and proteins but low in fats 1
Pain Management
- Implement multimodal analgesia with morphine or hydromorphone as first-line opioid analgesics 1
- Consider epidural analgesia for severe cases requiring high doses of opioids 1
- Monitor patients receiving morphine for potential complications:
Management of Complications
Biliary Pancreatitis Management
- ERCP is indicated in acute gallstone pancreatitis with cholangitis (grade 1B) 4
- ERCP is indicated in acute gallstone pancreatitis with common bile duct obstruction (grade 2B) 4
- Routine ERCP is not indicated for all patients with acute gallstone pancreatitis (grade 1A) 4
- Cholecystectomy should be performed during the same hospital admission for gallstone pancreatitis 1
Infected Necrosis and Collections
- Use a step-up approach for infected pancreatic necrosis, starting with percutaneous drainage 1
- Consider minimally invasive strategies such as transgastric endoscopic necrosectomy or video-assisted retroperitoneal debridement 1
- Postpone surgical interventions for more than 4 weeks after disease onset when possible 1
Intra-abdominal Hypertension
- Limit sedation, fluids, and vasoactive drugs to achieve resuscitative goals at lower normal limits 4
- Deep sedation and paralysis may be necessary to limit intra-abdominal hypertension if other treatments are insufficient 4
- Consider percutaneous drainage of intraperitoneal fluid before surgical abdominal decompression 4
Antibiotic Management
- Antibiotics should only be used for documented infections 1
- Maximum duration of 14 days for infected necrosis 1
- Use broad-spectrum antibiotics covering gram-negative, gram-positive, and anaerobic organisms when indicated 1
- Prophylactic antibiotics should not be used for sterile necrosis 1
Monitoring and Assessment
- Assess severity within 48 hours using clinical impression, laboratory markers (elevated C-reactive protein), and scoring systems 1
- Perform dynamic CT scanning within 3-10 days of admission for severe cases 1
- Manage patients with severe acute pancreatitis in a high dependency unit or intensive care unit with full monitoring and systems support 1
Special Considerations
- Be vigilant for refeeding syndrome in malnourished alcoholic patients 1
- Provide thiamine supplementation to prevent Wernicke's encephalopathy, especially in chronic alcoholics 1
- Implement strict glucose control using insulin therapy for managing hyperglycemia 1
- Correct electrolyte abnormalities, particularly potassium, magnesium, and phosphate 1
By following this comprehensive approach, mortality for severe acute pancreatitis should be kept below 30%, with overall mortality for all acute pancreatitis cases below 10% 1.
