Transmural gown pressures encountered when the surgeon comes into contact with a patient were measured in the operating theater. The surgical gown industry has assumed these pressures to be less than 5 psi in testing the efficacy of the gown and drape barrier material to impede bacterial transmission through its pores. In this study, pressure-sensitive contact film and resistive strain gauge recordings made from the surgeon's abdominal region and forearms indicated peak contact pressures in excess of 60 psi. This report indicates a need to reassess the basis of test utilization in evaluating barrier materials used in gowns and drapes.
在手术室中测量了外科医生接触患者时所遇到的跨壁手术衣压力。手术衣行业在测试手术衣和手术单屏障材料通过其孔隙阻碍细菌传播的功效时，假定这些压力小于5磅力/平方英寸。在本研究中，通过压敏接触膜和电阻应变仪对外科医生腹部区域和前臂进行记录，结果表明峰值接触压力超过60磅力/平方英寸。本报告表明有必要重新评估在评估手术衣和手术单中使用的屏障材料时测试应用的依据。
