Severe Acute Pancreatitis
- Patients with acute pancreatitis are considered to have severe acute pancreatitis (SAP) if they manifest signs of shock, respiratory failure, renal faliure, or GI bleeding.
- SAP is almost universally associated with pulmonary dysfunction, typically manifested as an SpO2 < 90% in the first few hours of illness.
- In fact, ARDS develops in at least one-third of patients with SAP.
- Take Home Point: Pay close attention to the patient with acute pancreatitis and a low pulse oximetry reading, as many will rapidly deteriorate from ARDS. In those who deteriorate, early intubation with implementation of lung protective ventilatory strategies is indicated.
