In 1975 a check list was introduced for the pre-operative evaluation of the surgical risks. In contrast to assessing the general condition of the patient according to the ASA nomenclature, the check list is largely based on objective criteria with a point system for evaluation. The number of points determines the magnitude of risk. 140,250 anaesthesias are avaluated with regard to the frequency of cardiovascular complications. The incidence of complications increases steadily in the presence of hypertension and arrhythmia in four consecutive risk groups and in the presence of hypotension and asystole in all five groups.
1975年引入了一份用于手术风险术前评估的检查表。与根据美国麻醉医师协会（ASA）命名法评估患者的一般状况不同，该检查表在很大程度上基于客观标准，并采用评分系统进行评估。分数的多少决定了风险的大小。针对心血管并发症的发生率，对140250例麻醉进行了评估。在四个连续的风险组中，高血压和心律失常会使并发症的发生率稳步上升，而在所有五个组中，低血压和心搏停止也会使并发症的发生率上升。
