Abstract
Fluorinated hydrocarbons have transformed inhalational anaesthesia, and vaporizers are essential for safe and accurate delivery of these agents. The modern-day vaporizers have evolved considerably since the ether inhaler invented by John Snow in 1847 and are robust, precise and efficient. For an anaesthetist to administer safe inhalational anaesthetic, it is important to understand the physical principles of the various inhalational anaesthetic agents along with the working principles of the vaporizers. Almost all modern vaporizers are located outside the circle system and the have multiple safety mechanisms in place.
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.
