Severe Acute Pancreatitis: Part 2 ICU Considerations

Severe acute necrotizing pancreatitis requires aggressive management in the intensive care unit, prioritizing rapid fluid resuscitation to address massive third-space sequestration. Because endothelial leak significantly reduces the intravascular retention of isotonic fluids, clinicians must monitor respiratory, cardiovascular, and renal status closely to prevent multi-organ dysfunction. While abdominal compartment syndrome remains a critical concern, diagnosis requires identifying the full syndrome—including elevated pressure, decreased urine output, and respiratory compromise—rather than relying solely on pressure readings. Nutritional strategies have shifted away from traditional pancreatic rest, with evidence favoring enteral nutrition over total parenteral nutrition to reduce infection risk and maintain gut integrity. Furthermore, regional anesthesia, such as epidural catheters, offers a viable alternative to systemic narcotics for pain control, potentially minimizing the risk of ICU delirium and cognitive dysfunction during recovery.
