Anaesthetics is the largest hospital-based speciality in the UK1 Anaesthetists work in all of the above fields. Anaesthetic care within the peri-operative pathway can only be provided by an anaesthesia team led by consultant anaesthetists. The anaesthetist alone can deliver anaesthesia autonomously. The only other non-medical staff permitted to deliver anaesthesia in the UK is the Physicians’ Assistant [Anaesthesia] who deliver anaesthesia under supervision by a Consultant Anaesthetist. The anaesthetist remains responsible for his patient throughout the perioperative journey until discharge from PACU. Whilst in PACU the recovery room nurse carries out anaesthetic orders and refers any major problem back to the anaesthetist in charge of the patient. The anaesthetist is required to have a trained practitioner2 [Anaesthetic Nurse or Operating Department Practitioner] working alongside him in the delivery of anaesthesia.
