Open Access Abstract Introduction Sepsis a systemic inflammatory response to infective etiologies has a high mortality rate that is linked both to excess cytokine activity and apoptosis of critical immune cells. Dexmedetomidine has recently been shown to improve outcome in a septic cohort of patients when compared to patients randomized to a benzodiazepine-based sedative regimen. We sought to compare the effects of dexmedetomidine and midazolam at equi-sedative doses on inflammation and apoptosis in an animal model of severe sepsis. Methods After central venous access Sprague Dawley rats underwent cecal ligation and intestinal puncture CLIP with an 18 G needle without antibiotic cover and received either saline or an infusion of comparable volume of saline containing midazolam or dexmedetomidine 5 for 8 hours. Following baseline measurements and CLIP blood was .
