AbstractIntestinal hypoperfusion is among the factors implicated in sepsis and multiorgan failure. Splanchnic blood flow may be sacrificed to maintain supply to vital organs, even when hemodynamic alterations are minor. The sensitivity of invasive hemodynamic monitoring for detecting intestinal hypoperfusion is low. This paper aims to review current knowledge about indirect measurement of splanchnic perfusion by way of gastrointestinal tonometry. We review the pathophysiology of ischemic intestinal lesions, the basis for gastrointestinal tonometry, and the method. Finally we discuss clinical applications (early diagnosis of ischemic colitis and ischemia of the flap after esophageal reconstruction, weaning from mechanical ventilation, abdominal compartment syndrome, liver transplant, heart surgery, prognostic factors and care of the critically ill patient). An adequate understanding of this monitoring technique and management of information it provides can give an early warning of the intestinal hypoperfusion that precedes other serious systemic complications.
