The output of inhalational agents from modern vaporisers are both electronically and pneumatically controlled. They are designed to deliver set agent concentrations accurately with low fresh gas flows and possess enhanced safety features. The purpose of this review article is to give an overview of three modern vaporisers, namely, the Aladin cassette vaporiser, injection vaporisers and AnaConDa™. The Aladin cassette is integrated with Datex Ohmeda S/5 ADU and GE Aisys anaesthesia machines. The electronic vapour control unit is incorporated within the anaesthesia machine. The agent specific cassettes act as a detachable vaporising chamber. The system can work as a variable bypass and measured flow vaporiser but requires a power supply to function. Injection vaporisers can achieve the set end-tidal agent concentration very rapidly with even metabolic flow rates. Hence, anaesthetic depth can be rapidly altered with minimal wastage and theatre pollution. The two types of injection vaporisers, namely, Maquet and DIVA™ are customised to function with Maquet FLOW-i and the Drager Zeus anaesthesia machine, respectively. AnaConDa™ is a combination of vaporiser and humidity and moisture exchange filter which can be fitted in the ventilatory circuit. It is primarily designed for use in intensive care for sedation and out of operating room use.
现代蒸发器吸入麻醉药的输出由电子和气动控制。它们旨在在低新鲜气体流量下准确输送设定的麻醉药浓度，并具有增强的安全功能。这篇综述文章的目的是概述三种现代蒸发器，即阿拉丁盒式蒸发器、注射式蒸发器和AnaConDa™。阿拉丁盒与Datex Ohmeda S/5 ADU和GE Aisys麻醉机集成。电子蒸汽控制单元内置在麻醉机内。特定药物盒用作可拆卸的蒸发室。该系统可以作为可变旁路和测量流量蒸发器工作，但需要电源才能运行。注射式蒸发器即使在代谢流量率均匀的情况下也能非常迅速地达到设定的呼气末麻醉药浓度。因此，麻醉深度可以迅速改变，浪费和手术室污染最小。两种注射式蒸发器，即Maquet和DIVA™，分别定制为与Maquet FLOW-i和德尔格宙斯麻醉机配合使用。AnaConDa™是蒸发器与湿度和水分交换过滤器的组合，可安装在通气回路中。它主要设计用于重症监护中的镇静和手术室以外的使用。
