This trial investigates the sedation effects of intravenous dexmedetomidine in healthy males and its impact on ventilation and metabolic parameters.
Double-blind, placebo-controlled design; assessed four dose levels of DMED (0.25, 0.5, 1.0, 2.0 micrograms/kg); N=37 healthy volunteers.
Evaluated sedation, arterial blood gases, ventilation, and metabolic rates at various time intervals post-infusion.
At doses of 1.0 and 2.0 micrograms/kg, sedation caused loss of responsiveness for 195 min (P < .05).
PaCO2 increased significantly by 5.0 mmHg (1.0 μg/kg) and 4.2 mmHg (2.0 μg/kg) post-infusion (P < .05).
Ventilation decreased by 28% at 60 min following 2.0 micrograms/kg (P < .05), returning to normal by 285 min.
