Anaesthesia is controlled during surgery by a highly trained anaesthetist using clinical signs from the patient, combined with experience, to gauge the depth of anaesthesia and to manipulate the administration rate of anaesthetic drugs. Modern anaesthesia frequently uses a cocktail of agents including anaesthetics, analgesics and muscle relaxants which complicates considerable the assessment of the depth of anaesthesia. Help may be at hand using acoustical methods. Hearing tests are often based upon measuring the response of the auditory system to a series of click stimuli and this approach may have potential for assessing consciousness. Novel methods of stimulating the auditory system will be described which show promise for application to both audiology and anaesthesia.
