[Optimization of hepatosplanchnic oxygenation in septic shock]

Microcirculatory dysfunction, reduced oxygen supply and thus impaired hepatosplanchnic organ function, play a pivotal role in the clinical manifestation of sepsis and septic shock. Early correction of the perfusion mismatch is essential to maintain end-organ and gut mu-cosa barrier function and thus to prevent bacterial translocation, bacteraemia and possible multiple organ failure. This review will outline the clinical tightrope-walk optimizing hepa-tosplanchnic oxygen supply while maintaining adequate end-organ perfusion pressure and highlight the diagnostic challenges and limitations faced in clinical practice.
