These findings suggest that a single-dose bolus injection of dexmedetomidine before tracheal extubation attenuates airway-circulatory reflexes during extubation.

When used for AVF access surgery, infraclavicular brachial plexus block provides higher blood flow in the radial artery and AVF than is achieved with infiltration anesthesia.

Addition of dexmedetomidine to local anaesthetic solution in IVRA improved the quality of anaesthesia and decreased analgesic requirements, but had no effect on the sensory and motor blocks onset and regression times.

Premedication with low-dose intravenous dexmedetomidine, 0.5 microg x kg(-1) or midazolam, 0.025 mg x kg(-1) before ECT may be useful in managing treatment-resistant agitation after ECT, without adverse effects.

Respiratory function and mucociliary clearance are better preserved in a low-flow anaesthesia technique than in high-flow anaesthesia with nitrous oxide and desflurane. Therefore, a low-flow anaesthesia technique with nitrous oxide and desflurane may provide an important clinical advantage because it provides appropriately heated and humidified gases to the tracheobronchial tree.
