静脉麻醉药可根据其化学,起效快慢或临床是否受欢迎等加以分类。某药作用时间虽与使用范围关系密切,但用它来分类却不合适。不加区别地使用所谓“超短作用”或“短效”,而不了解其药物代谢动力学,则往往引起误解和误用。如果根据起效速度和化学,则静脉麻醉药可分成两大类:(一)快速作用类(作麻醉诱导用)如硫喷妥钠、甲 Intravenous anesthetics can be classified according to their chemistry, their onset of efficacy, or their clinical popularity. Although the role of a drug with the use of time is closely related, but it is not suitable for classification. The indiscriminate use of so-called “short-acting” or “short-acting” without understanding its pharmacokinetics often leads to misunderstandings and misuse. If based on the onset rate and chemistry, intravenous anesthetics can be divided into two broad categories: (a) rapid acting class (for induction of anesthesia) such as thiopental sodium
