Fig 2 Certain/probable and possible accidental awareness during general anaesthesia cases by speciality (bars) compared with distribution in the activity survey (dots and line). Three cases in bariatric and transplant surgery have been omitted as they were not specified in the activity survey. ENT, ear, nose, throat; maxfax, maxillofacial surgery; ortho, orthopaedic surgery; eye, ophthalmology; X-ray, radiology; general surgery includes urology and other specialities not listed.

Fig 3 Representation of some components of anaesthesia practice in certain/probable and possible accidental awareness during general anaesthesia reports (bars) compared with distribution in the activity survey (dots and lines). Propofol in first bar refers to its use as an induction agent, as distinct from a later bar (TIVA) where its use is referred to for maintenance. TIVA, total i.v. anaesthesia; TCI, target-controlled infusion; N2O, nitrous oxide; RSI, rapid sequence induction; NMB, neuromuscular block; DOA, specific depth of anaesthesia monitor.

Fig 4 A proposed NAP5 anaesthesia component (AC) checklist of the World Health Organization checklist (NAP5 AC-WHO). The ABCDE check should be undertaken before commencing surgery (at the WHO surgical pause) and after each occasion the patient is moved.
