fixation error illustrates the need for careful reevaluation of all the clinical information when a problem in anaesthesia is not resolved by initial diagnosis and intervention. In view of the high incidence of fixation error [3], we suggest that this problem should be addressed during introductory training in anaesthesia, in order that all anaesthetists are aware of it. As critical incidents such as the one we describe are relatively uncommon, anaesthetic simulators may have a useful role in reducing the incidence of fixation error.
