Brief Summary:
The aim of this observative, prospective study with cross-sectional design is to explore possible correlations/associations between microcirculation parameters and sublingual endothelial glycocalyx in sepsis. Therefore, 30 critically ill septic patients and 10 healthy controls were enrolled.

Group/Cohort Intervention/treatment
Septic patients
ICU patients with resuscitated sepsis, based on the sepsis-3 criteria. (n=30)
Other: Microcirculation and Glycocalyx assessment
Non-invasive assessment of endothelial glycocalyx dimensions (PBR) and microcirculatory parameters (e.g. PPV, PVD, TVD, MFI)

Healthy controls
Apparently healthy controls (n=10)
Other: Microcirculation and Glycocalyx assessment
Non-invasive assessment of endothelial glycocalyx dimensions (PBR) and microcirculatory parameters (e.g. PPV, PVD, TVD, MFI)




Primary Outcome Measures :
  1. Correlations between Perfused Boundary Region (PBR) and Microvascular Flow Index (MFI) measured sublingually [ Time Frame: During ICU stay, an average of 2 days after sepsis onset ]
    Glycocalyx thickness will be measured with PBR (in μm) and MFI will be assessed in points. Possible correlations at a given timepoint will be explored (e.g. Spearman's Correlation).

  2. Correlations between Perfused Boundary Region (PBR) and Proportion of Perfused Vessels (PPV) measured sublingually [ Time Frame: During ICU stay, an average of 2 days after sepsis onset ]
    Glycocalyx thickness will be measured with PBR (in μm) and PPV will be assessed in percentage. Possible correlations at a given timepoint will be explored (e.g. Spearman's Correlation).

  3. Correlations between Perfused Boundary Region (PBR) and Perfused Vessel Density (PVD) measured sublingually [ Time Frame: During ICU stay, an average of 2 days after sepsis onset ]
    Glycocalyx thickness will be measured with PBR (in μm) and PVD will be assessed in mm/mm^2. Possible correlations at a given timepoint will be explored (e.g. Spearman's Correlation).
