Anaesthesia peri-operative care, and Critical Care provision form an integral part of burns care and are thus part of this resuscitation anaesthesia change. Bringing burns critical care in line with modern general adult and paediatric in- tensive care is highly desirable, but will need to be achieved with minimal disruption to continuity of service and with careful attention to sta¡ retention. National,College and Association Guidelines for service provision and training should inform the strategy for recon¢guring local burns services and be applied appropriately to ensure that change, once achieved, is for the better.Where possible these guidelines should be appliedlocally to optimize the anaesthetic and critical care of burned patients in advance of wider ser- vice recon¢guration. 2002 Published by Elsevier Science Ltd. cHISTORYAND BACKGROUND largely made on historical grounds, and the units devel- oped locally with plastic surgery, according to localThe care of patients with burn injuries underwent need and desire, and largely independent of onemajor changes during the last century.

Guidelines should be available for immediate care and transfer (2) Burns centres provide care for complex injuries with large TBSA; Burns Units provide care for complex injuries with small TBSA;Burn facilities provide care for non-complex injuries (3) The responsibility for critical care of burned patients should be shared between burns anaesthetists/intensivists, and burns surgeons. (4) The critical care of burned patients is an integral part of burns anaesthesia services. Specialist departments need to provide protocols, sta¡ training, and rapid availability of resources (5) Provision of beds for burnintensive care must be adequate.With su⁄cient workload these willbein a Burns ICUwithin a Burns centre.With lesser workloads they will be in general ITU or paediatric intensive care unit (PICU) (6) Critical care beds for burns patients need to be in close proximity to an operating theatre and other support facilities (7) Major burn anaesthesia should only take place in a Burns Centre or Burns Unit with full consultant cover (8) Paediatric burn cases require special facilities and sta⁄ngK anaesthesia thorough training in all aspects of anaesthesia for burns,K peri-operative care. plastic and reconstructive surgery.
