The use of oxygen increases the risk of fire during ophthalmic surgery. A prospective clinical study was conducted involving 100 patients without pulmonary disease who had cataract surgery under local anesthesia using either oxygen or compressed air. No clinically significant difference in oxygen saturation between the two groups was found. There was no statistically significant difference in the net change in saturation, and the significant difference found in overall mean saturation between the two groups was invalidated by inherent machine error. Using compressed air instead of oxygen is suggested to reduce fire hazard during ophthalmic surgery.
在眼科手术中使用氧气会增加火灾风险。进行了一项前瞻性临床研究，纳入100例无肺部疾病的患者，这些患者在局部麻醉下接受白内障手术，术中使用氧气或压缩空气。两组之间的氧饱和度未发现临床上的显著差异。饱和度的净变化在统计学上无显著差异，且两组总体平均饱和度之间发现的显著差异因仪器固有误差而无效。建议在眼科手术中使用压缩空气代替氧气以降低火灾风险。
