Effect of Dexmedetomidine on Perfusion Index and Microcirculation in Severe Sepsis and Septic Shock Patients

Summary

Septic shock is one of the major causes of death worldwide with in-hospital mortality rates varying between (11.9% to 47.2 %). Alterations in microcirculatory blood flow were associated with high risk of organ dysfunction and death. Experimental studies on septic rats revealed that dexmedetomidine treatment can effectively reduce the generation of inflammatory mediators and yields beneficial effects on endotoxemic animals' microcirculation.
