Metallic tapes have been shown to protect combustible endotracheal tubes from the CO2 laser; however, no adequate means of protecting such tubes from the Nd-YAG laser has yet been found. In this investigation, five different metallic tapes were evaluated as protection for red rubber endotracheal tubes from an Nd-YAG laser set to 50 W. Radio Shack no. 44-1155 and 3M no. 1430 were quickly perforated by the laser. Laser contact with the adhesive side of 3M no. 433 resulted in combustion. The nonadhesive side of the Venture copper tape was not affected by the laser; however, when its adhesive side was struck, a fire occurred. 3M no. 425 tape provided the best protection: no effect was seen when the laser was aimed at its nonadhesive side for 1 min, with only smoking of the tape evident when its adhesive side was tested. Finally, 3M no. 425 and Venture copper foil tapes were shown to be resistant to an Nd-YAG laser set to 110 watts in an atmosphere of 98% O2.
金属带已被证明可保护可燃气管插管免受二氧化碳激光的影响；然而，尚未找到保护此类插管免受钕钇铝石榴石激光影响的适当方法。在本研究中，评估了五种不同的金属带对红色橡胶气管插管免受设置为50瓦的钕钇铝石榴石激光的保护作用。Radio Shack 44 - 1155号和3M 1430号金属带很快就被激光穿孔。激光照射3M 433号的粘性面会导致燃烧。Venture铜带的非粘性面不受激光影响；然而，当激光照射其粘性面时，发生了火灾。3M 425号带提供了最佳保护：当激光照射其非粘性面1分钟时未见影响，测试其粘性面时仅见胶带冒烟。最后，在98%氧气的气氛中，3M 425号带和Venture铜箔带被证明能抵抗设置为110瓦的钕钇铝石榴石激光。
