A 12-kg infant was given intravenous dexmedetomidine 0.2 µg kg min as an adjunct for general anesthesia. The 60-fold increase in dexmedetomidine infusion rate caused a biphasic response with initial hypertension followed by bradycardia and hypotension requiring inotropic support. No postoperative or long-term sequelae were noted. Dexmedetomidine infusion is usually delivered as µg kg h .
