Abstract
Inhalational anaesthesia is conducted via the use of volatile agents and predates the use of intravenous anaesthesia. Volatile agents can be used to induce and maintain anaesthesia; the choice of agent relies on an understanding of the individual physical properties of each agent. This article describes these properties including the blood: gas coefficient, oil: gas coefficient, minimum alveolar concentration (MAC) and saturated vapour pressure (SVP). Delivery of inhalational anaesthesia to the patient and depth of anaesthesia monitoring is then discussed together with vaporizer function. Lastly, there is a discussion of the environmental impact of inhalational agents including nitrous oxide with reference to the proposed future agent xenon.
期刊介绍：
Anaesthesia and Intensive Care Medicine, an invaluable source of up-to-date information, with the curriculum of both the Primary and Final FRCA examinations covered over a three-year cycle. Published monthly this ever-updating text book will be an invaluable source for both trainee and experienced anaesthetists. The enthusiastic editorial board, under the guidance of two eminent and experienced series editors, ensures Anaesthesia and Intensive Care Medicine covers all the key topics in a comprehensive and authoritative manner. Articles now include learning objectives and eash issue features MCQs, facilitating self-directed learning and enabling readers at all levels to test their knowledge. Each issue is divided between basic scientific and clinical sections. The basic science articles include anatomy, physiology, pharmacology, physics and clinical measurement, while the clinical sections cover anaesthetic agents and techniques, assessment and perioperative management. Further sections cover audit, trials, statistics, ethical and legal medicine, and the management of acute and chronic pain.
