Introduction: Dexmedetomidine and midazolam are frequently used to maintain sedation in mechanically ventilated patient in intensive care unit. The study compared dexmedetomidine and midazolam infusion in mechanically ventilated patient in terms providing effective sedation. Methods: This was one year prospective comparative study conducted in 130 mechanically ventilated patients who were randomly divided in two groups receiving either dexmedetomidine or midazolam infusion for sedation. Sedation level was assessed by Riker Sedation-Agitation Scale with the aim of maintaining target sedation score of 3 to 4. The two drugs were compared in terms of sedation level in first 24 hours, time required to achieve target sedation level, hemodynamic changes and adverse effects including ICU delirium. The outcome was measured in terms of duration of mechanical ventilation, length of ICU stays and ICU mortality. Results: Both dexmedetomidine and midazolam achieved target sedation level in a co...

Dexmedetomidine in the Care of Critically Ill Patients from 2001 to 2007
Anesthesiology, 2010
Background Dexmedetomidine is a novel sedative agent that causes anxiolysis without respiratory depression in critically ill patients. We sought to examine patient and hospital variation in dexmedetomidine use and adoption patterns of dexmedetomidine over time. Methods We performed a retrospective cohort study of all patients who received intravenous infusion sedation in 174 intensive care units contributing data to Project IMPACT from 2001 through 2007. Sedation use was defined as having received an intravenous sedative infusion (dexmedetomidine, midazolam, lorazepam, or propofol) for any period during the intensive care stay. The primary outcome was use of dexmedetomidine in the intensive care unit. Results Of 58,391 patients who received intravenous infusion sedation, 2,535 (4.3%, 95% confidence interval [CI], 4.2-4.5) received dexmedetomidine. Overall use was highest in cardiac surgery patients (11.7%, 10.8-12.7) and was similar in other surgical patients (4.3%, 4.0-4.6) and med...
