Fires in the operating room continue to present a hazard to patients, at times with catastrophic and debilitating results. Recent data from closed claim files reveal oxygen, electrosurgical unit (ESU), and surgical drapes are common components of the fire triangle in the operating room. In this era of biotechnological sophistication, why are surgical drapes flammable? The purpose of this study was to test the flammability of different surgical drape materials and to determine the time to ignition using a bipolar ESU device in 21%, 35%, and 100% oxygen concentrations. Results show that regardless of oxygen concentration surgical drapes, when exposed to close contact with the ESU, are flammable. Time to ignition decreases with increasing concentrations of oxygen as expected. One of the surgical drapes tested was advertised to the hospital as nonflammable. Future research should focus on surgical drape materials and aim to reduce the flammability of such items in the operating room.
手术室火灾持续对患者构成危害，有时会造成灾难性和使人衰弱的后果。来自结案索赔文件的最新数据显示，氧气、电外科设备（ESU）和手术单是手术室火灾三角的常见组成部分。在这个生物技术复杂的时代，为什么手术单是易燃的呢？本研究的目的是测试不同手术单材料的可燃性，并确定在21%、35%和100%氧气浓度下使用双极ESU设备时的着火时间。结果表明，无论氧气浓度如何，手术单在与ESU紧密接触时都是易燃的。正如预期的那样，着火时间随着氧气浓度的增加而减少。测试的其中一种手术单在医院宣传中被称为不可燃。未来的研究应聚焦于手术单材料，并致力于降低此类物品在手术室的可燃性。
