MIcrovascular Dysfunction in CRitically Ill cOVID-19 Patients

Microcirculatory dysfunction appears to play a key role in the development of organ failure leading to the death of patients with coronavirus disease 2019 (Covid-19). It is still uncertain today whether this damage is secondary to direct viral infection of endothelial cells or the consequence of the inappropriate inflammatory response induced by the infection. The analysis of endothelial and microcirculatory dysfunctions and glycocalyx degradation therefore appears to be necessary in the understanding of the pathophysiological mechanisms of Covid sepsis and could play a role in the evaluation of the efficacy of certain therapeutics which would aim at improving regional perfusion by decreasing microcirculatory dysfunction.However, the analysis of microcirculatory failure, endothelial dysfunction and glycocalyx degradation has so far only been evaluated in small cohorts, without quantitative analysis of microcirculatory perfusion
