Clinical review: Clinical imaging of the sublingual microcirculation in the critically ill - where do we stand?
A growing body of evidence exists associating depressed microcirculatory function and morbidity and mortality in a wide array of clinical scenarios. It has been suggested that volume replacement therapy using fluids and/or blood in combination with vasoactive agents to modulate macro- and microvascular perfusion might be essential for resuscitation of severely septic patients. Even after interv...

Introduction Microcirculatory dysfunction may result in multiple organ dysfunction during severe sepsis and septic shock. (1) A meta-analysis of randomized trials showed that polymyxin B hemoperfusion (PMX-HP), plasma exchange, and hemofiltration were associated with lower mortality. (2) Mesenteric microcirculation was better maintained with polymyxin B hemoperfusion in one rat sepsis study. (3...
متن کاملMicrovascular resuscitation as a therapeutic goal in severe sepsis
Sepsis causes microvascular dysfunction. Increased heterogeneity of capillary blood flow results in local tissue hypoxia, which can cause local tissue inflammation, impaired oxygen extraction, and, ultimately, organ dysfunction. Microvascular dysfunction is clinically relevant because it is a marker for mortality: it improves rapidly in survivors of sepsis but fails to improve in nonsurvivors. ...
متن کاملImpairments in microvascular reactivity are related to organ failure in human sepsis.
Severe sepsis is a systemic inflammatory response to infection resulting in acute organ dysfunction. Vascular perfusion abnormalities are implicated in the pathology of organ failure, but studies of microvascular function in human sepsis are limited. We hypothesized that impaired microvascular responses to reactive hyperemia lead to impaired oxygen delivery relative to the needs of tissue and t...
متن کاملEffects of crystalloids and colloids on liver and intestine microcirculation and function in cecal ligation and puncture induced septic rodents
BACKGROUND Septic acute liver and intestinal failure is associated with a high mortality. We therefore investigated the influence of volume resuscitation with different crystalloid or colloid solutions on liver and intestine injury and microcirculation in septic rodents. METHODS Sepsis was induced by cecal ligation and puncture (CLP) in 77 male rats. Animals were treated with different crysta...
