A prospective study of the influence of radiological findings upon operation policy was carried out in 810 patients over 40 years of age who underwent elective non cardiopulmonary surgery. Only in 5 patients did it appear that a preoperative X-ray yielded any relevant extra information, and only in 3 cases was the operation planning influenced. If no preoperative chest X-rays has been taken, all except one of the significant abnormalities would have been discovered anyway. By differentiating between patients graded ASA 1 and those classed ASA 2 or higher, it would be possible to reduce the number of preoperative chest X-rays by 41% without any loss of precision. Preoperative chest X-rays in patients over 40 years of age scheduled for non-cardiopulmonary surgery can be restricted to those whose history requires further radiological analysis.
对810例40岁以上接受择期非心肺手术的患者进行了一项关于放射学检查结果对手术策略影响的前瞻性研究。只有5例患者术前X线检查显示出任何相关的额外信息，且只有3例手术计划受到影响。如果未进行术前胸部X线检查，除1例之外的所有显著异常无论如何都会被发现。通过区分ASA 1级患者和ASA 2级或更高等级患者，有可能将术前胸部X线检查的数量减少41%，而不会有任何精度损失。计划进行非心肺手术的40岁以上患者的术前胸部X线检查可仅限于那些病史需要进一步放射学分析的患者。
