Primary Outcome Measures:
  • Relation between MFI (by SDF) and capno [ Time Frame: 6 months ]

Secondary Outcome Measures:
  • Relevance of changes in flow and metabolism [ Time Frame: 6 months ]

Estimated Enrollment: 30

Detailed Description:
Sidestream Darkfield imaging is used to determine rectal microcirculatory flow in patients after postoperative cardiac surgery. At the same time PCO2 gap is established by monitoring rectal CO2 (tonometry) and arterial CO2 After initial enrollment and first analysis we also includes a control group with equal inclusion criteria for sublingual SDF imaging.
