Amnesia, Analgesia, Depression of reflexes, Muscle relaxation (puts patients to sleep)
What is the definition of regional anaesthesia?
A reversible loss of sensation in a specific area/region of the body when a local anaesthetic in injected to purposefully block or anaesthetise nerve fibres in and around the operative site

Decrease anxiety, reduce bronchial secretions, analgesia, amnesia
What do Sedatives/tranquilizers do?
Sedation and amnesia, calm hypnotic state (examples:benzodiazepines, Barbiturates)
What do narcotics do?
Raise pain threshold, lower metabolic rate, decrease anaesthetic required
What do Anticholinergics do?
interfere with stimulation of vagus nerve, prevent vagal mediated hypotension, cardiac arrhythmias, bradycardia
What do Antiemetics do?
Minimise N/V (eg phenergan, maxalon, ondansetron)
3-4 Phases of General anaesthetic?
Induction, Maintenance, Emergence, Recovery (can be considered 4th)
Forms of GA
IV, Inhalation, Combination
What are the GA inhalation agents? (4)
