Diagnostik von Mikrozirkulationsstörungen beiSchockpatienten

: The microcirculatory status depicts an indicator of organ perfusion in hemodynamic shock. Distribution pattern of microcirculatory disturbances reflects the underlying cause of shock: In septic shock, organ perfusion is severely impaired via arteriolo-venous shunting with shutting up small vessel perfusion; however, cardiogenic shock is characterized by a global impairment of microcirculation, involving all vascular beds. Hence, a differentiated evaluation of microcirculatory disturbances not only supports an early diagnosis of an imminent multiorgan dysfunction syndrome (MODS), but also allows a more accurate evaluation of severity of hemodynamic compromise in critical care medicine. Bedside sidestream darkfield (SDF) technique offers the opportunity to describe the microcirculatory status quo semiquantitatively and to evaluate the effect of novel therapeutic approaches on microcirculation. Further technical improvements of this technique may open new fields of diagnostic and therapeutic applications in intensive care medicine by supporting an early diagnosing of MODS, evaluating prognosis, and optimizing therapeutic measures .
