Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Patients who require cystoscopy, hysteroscopy or TRUS biopsy will be given an anaesthetic regimen based on dexmedetomidine. The procedures will be a one off.

Dexmedetomidine will be given intravenously (IV). Patients will receive a loading dose of 1 microgram per kilogram over 10 minutes. The design of the study incorporates the potential for this loading dose to increase or decrease as data about the response from patients is included.

After the loading dose, patients will be maintained on an infusion that will be adjusted according to response from between 0.2 micrograms / kilogram / hour and 1.4 micrograms / kilogram /hour.

The infusion will be maintained for the duration of the procedure. The procedures are expected to last for less than 30 minutes.
