Management
Pancreatic necrosis
- Two forms
- Acute necrotizing pancreatitis, which is present at the start, and is usually phlegmonous
- Walled-off necrosis, which develops over the course of illness, and is usually an organized collection
- Both are sterile and both can become infected
- No antibiotics warranted in acute necrotizing pancreatitis
- Infection usually develops after about 10 days
- If necrosectomy is indicated, it should be delayed by at least 4 weeks
Splenic vein thrombosis
- Monitor
Prognosis

- BUN increase >5 mg/dL (>1.79 mmol/L) from admission
- Ca <8 mg/dL (<2 mmol/L) within 48 hours
- Arterial pO2 <60 mmHg within 48 hours
- Base deficit (24 - HCO3) >4 mg/dL within 48 hours
- Fluid needs > 6L within 48 hours
BISAP
- BUN > 8.9
