Topic overview

Start with the big picture

Anaesthesia uses pharmacological techniques to suppress consciousness, sensation or movement as needed for procedures. General anaesthesia produces reversible loss of consciousness, amnesia, analgesia and immobility; regional anaesthesia blocks conduction in a localized area while preserving consciousness. Other approaches include monitored anaesthesia care, moderate sedation, balanced anaesthesia, total intravenous anaesthesia and total inhalational techniques. The topic also considers rapid sequence induction, pre-anaesthetic assessment and preparation, and monitoring during anaesthesia. These techniques differ in their aims and practical requirements, so understanding their features helps frame how anaesthetic care is tailored to the patient and procedure. The lesson further addresses regional anaesthesia’s advantages and contraindications, post-anaesthesia care, enhanced recovery protocols and key complications.
