气道手术为手术室火灾的发生提供了独特的环境。本研究的目的是探讨在离体模型中使用高流量氧气的KTP激光时燃烧的因素。测试的变量是在不锈钢模型中改变组织类型、组织状况、氧浓度、激光设置和排烟。结果测量是激光发射到第一个火花和/或火焰的时间。使用多变量考克斯比例风险模型确定不同风险因素中火花和火焰的风险。氧气浓度在60%以上每增加10%，发生火焰的风险就增加2.3倍。2.6 W的连续激光设置使风险增加72.8倍。激光照射脂肪组织的风险是肌肉的7.3倍。烧焦的组织会增加92.8倍的火灾风险。93.6%的情况下，火焰在没有先前火花的情况下发生。在低功率脉冲模式下使用KTP激光器，最大限度地减少激光发射时间，降低氧气浓度并避免激光发射脂肪或烧焦组织，产生火花或火焰的估计风险相对较低。
Airway surgery presents a unique environment for operating room fire to occur. This study aims to explore the factors of combustion when using KTP laser with high flow oxygen in an ex-vivo model. The variables tested were varying tissue type, tissue condition, oxygen concentration, laser setting, and smoke evacuation in a stainless-steel model. Outcome measures were time of lasing to the first spark and/or flame. A multivariate Cox proportional hazard model was used to determine the risk of spark and flame across the different risk factors. For every 10% increase in oxygen concentration above 60% the risk of flame increased by a factor of 2.3. Continuous laser setting at 2.6 W increased the risk by a factor of 72.8. The risk of lasing adipose tissue is 7.3 times higher than that of muscle. Charred tissue increases the risk of flame by a factor of 92.8. Flame occurred without a preceding spark 93.6% of the time. Using KTP laser in the pulsed mode with low wattages, minimising lasing time, reducing the oxygen concentration and avoiding lasing adipose or charred tissue produce a relatively low estimated risk of spark or flame.
