[Splanchnic hypoperfusion and distant organ injury]

Area of Science:

• Critical care medicine
• Surgical intensive care
• Gastroenterology

Context:

• Acute respiratory distress syndrome (ARDS) and multiple organ failure (MOF) are primary causes of mortality in surgical intensive care units.
• Systemic inflammatory response, triggered by major surgery, trauma, shock, thermal injury, pancreatitis, and ischemia-reperfusion, contributes to ARDS and MOF.
• Splanchnic hypoperfusion is frequent in critically ill patients.

Purpose:

• This review focuses on intestinal ischemia-reperfusion events.
• It examines the link between gut circulation and distant organ injury.
• The review highlights the predictive value of assessing gut circulation adequacy for patient outcomes.

Summary:

• Intestinal ischemia-reperfusion injury initiates a systemic inflammatory cascade.
• Adequacy of gut circulation is a key predictor of outcomes in critically ill patients.
• Monitoring splanchnic circulation aids in managing patients at risk for ARDS and MOF.

Impact:

• Understanding intestinal ischemia-reperfusion is crucial for improving critical care.
• Assessing gut circulation offers a valuable prognostic tool.
• This knowledge can guide therapeutic strategies to mitigate distant organ injury and enhance survival rates.
