Loss of hemodynamic coherence is a phenomenon in critically ill patients.

Due to inflammatory events and endothelial remodeling, macro- and microhemodynamics are decoupled from each other, resulting in microcirculatory disturbances and end organ ischemia despite adequate vital parameters. Nailfold videocapillaroscopy NVC , however, is an established and easy method for visualization of the microcirculation in chronic diseases.
We here evaluated NVC in critically ill patients and compared its use with consensus microcirculatory assessment of IDF-microscopy. Evaluation of the CapMic score in 10 healthy volunteers at rest and under iatrogenic limb ischemia showed robust changes 0. Both sublingual and nailfold microcirculation deteriorated under rising norepinephrine- and crystalloid volume-requirements.

NVC-imaging provides comparable information on the microcirculation in critically ill patients compared to sublingual IDF microscopy.
