Office-based anaesthesia: the UK perspective1 Directorate of Anaesthesia, Keele Uni6ersity, North Staffordshire Hospital, Stoke-on-Trent, Staffordshire ST4 6QG, UK Abstract
Although office-based anaesthesia is not prevalent in the United Kingdom, anaesthesia has long been provided in community dental surgeries. Because of concerns over the safety of providing anaesthesia in hazardous remote locations, several expertworking parties have examined UK dental anaesthesia and made numerous recommendations for safe practice. Concerningtraining, general anaesthesia, sedation, equipment, monitoring, resuscitation and building layout, these recommendations providean excellent basis for local, regional or national guidelines for many forms of office-based anaesthesia. Putting the recommenda-tions into practice, however, has had a fundamental impact on the provision of UK dental anaesthetic services and may havesignificant cost implications. These aspects should be carefully considered by anyone involved with planning or deliveringoffice-based anaesthesia. 1998 Elsevier Science B.V. All rights reserved.
