The American Society of Anesthesiologists classification of physical status (ASA PS) is a widely used system for categorizing the preoperative status of patients. The ASA class is a good independent predictor of perioperative morbidity and mortality. The definitions of the ASA classes have been amended several times since 1941, resulting in inconsistent and confusing usage in the current literature. Conflicting definitions of ASA PS exist, particularly for classes III, IV and V. The high variability of individual classifications by different anesthesiologist, however, can be explained by the previous lack of examples for diagnoses. In 2014, the ASA has added a catalogue of examples for a simplified definition for classification of the ASA PS. This has so far received limited attention in German-speaking countries. This article describes the transition of the ASA classification over the past 75 years und summarizes the currently valid definitions.
美国麻醉医师协会身体状况分类（ASA PS）是一种广泛用于对患者术前状况进行分类的系统。ASA分级是围手术期发病率和死亡率的良好独立预测指标。自1941年以来，ASA分级的定义已多次修订，导致当前文献中的使用不一致且令人困惑。ASA PS存在相互冲突的定义，特别是对于III、IV和V级。然而，不同麻醉医师对个体分类的高度变异性可以用之前缺乏诊断示例来解释。2014年，ASA增加了一个示例目录，用于简化ASA PS分类的定义。到目前为止，这在德语国家受到的关注有限。本文描述了过去75年中ASA分类的转变，并总结了当前有效的定义。
