Anaesthetists are expected to develop and maintain expertise in procedural skills with low or zero tolerance for error. The more complex technical skills, as required for advanced airway management or ultrasound-guided procedures, require expertise in navigation, hand-eye coordination, and visualizing distant structures. Furthermore, learning and maintaining skills on patients is no longer acceptable when alternatives exist. Reduced working hours further limit opportunities for the traditional experiential learning of advanced procedural skills.Our surgical colleagues, faced with similar issues, have responded over the last few decades with extensive research and innovation aimed at optimising procedural performance and reducing error. Simulation and skills laboratories are now required by the Accreditation Council for Graduate Medical Education American (ACGME) and the research questions have moved from does simulation work to defining the elements of skills training and pre-procedure preparation that work best in different contexts. 1 However, even our surgical colleagues have struggled to integrate simulation-based skills programs into the regular training environment. The pre-procedural warm-up, by bringing simulators into the theatre suite, may help to embed simulation practice into the standard preparation for surgery. A further approach, also the subject of recent intense research activity, is mental imagery, a structured process of mental rehearsal prior to the procedure. Warm-up and mental imagery are well established in sports and the arts prior to a performance, and increasing evidence supports their value in surgery in improving performance and reducing procedural error.In this issue, Samuelson and colleagues 2 describe a warm-up for fibre-optic intubation (FOI) for anaesthesia trainees. They randomised subjects to a control group with no warm-up and an intervention group who undertook a 5-minute warm-up using a series of cases of varying difficulty on a virtual reality bronchoscopy simulator. Subsequent performance of asleep FOI in healthy patients with no anticipated airway difficulties showed significantly better performance in the warm-up group. I could find no other studies reporting pre-procedural warm-up in anaesthesia and only one on mental imagery. 3 Of relevance, Wright and colleagues 4 reported that the rates of errors, such as administering the wrong medication or blood, inadequate depth of anaesthesia, and oesophageal intubation, decrease after the first operations of the day, suggesting that anaesthetists' performance may improve after a period of warm-up.I undertook a Medline search of the literature on warm-up and mental imagery for procedural skills and provide here a narrative review with reference to potential application in anaesthesia.
