Stress Ulcer Prophylaxis in the Intensive Care Unit

Stress Ulcer Prophylaxis in the Intensive Care Unit (SUP-ICU)

Stress ulcer prophylaxis (SUP) is standard of care in the intensive care unit (ICU), however the quantity and quality of evidence is low and potential harm has been reported.

The aim of the SUP-ICU trial is to asses the overall benefits and harms of SUP with proton pump inhibitor in adult critically ill patients in the ICU.

Critically ill patients in the ICU are at risk of stress related gastrointestinal (GI) bleeding, and SUP is recommended. However, the quantity and quality of evidence supporting SUP is low and has been questioned. Furthermore studies have shown that proton pump inhibitors (PPIs) may increase the risk of pneumonia, clostridium difficile infection and acute myocardial ischemia. The aim of the SUP-ICU trial is to assess the benefits and harms of SUP with PPI in adult critically ill patients in the ICU.

INCLUSION CRITERIA:

  • Acute or chronic intermittent or continuous renal replacement therapy
  • Invasive mechanical ventilation which is expected to last > 24 hours
  • Coagulopathy (platelets < 50 x 109/l or international normalized ratio (INR) > 1.5 or prothrombin time (PT) > 20 seconds) documented within the last 24 hours
  • Ongoing treatment with anticoagulant drugs (prophylaxis doses excluded)
  • History of coagulopathy (platelets < 50 x 109/l or INR > 1.5 or PT > 20 seconds) within 6 months prior to hospital admission
  • History of chronic liver disease (portal hypertension, cirrhosis proven by biopsy, computed tomography (CT) scan or ultrasound, history of variceal bleeding or hepatic encephalopathy in the past medical history)
