Physicians' Assistants (Anaesthesia) (PA(A) s) were introduced in the UK almost a decade ago, and are now established within many NHS hospitals. PA(A)s are highly trained and skilled practitioners that work within an anaesthetic team under the direction and supervision of a consultant anaesthetist. These professionals are involved in all aspects of general anaesthesia delivery and some organisations have trained PA(A)s to additionally perform regional and local anaesthesia procedures.
