Mastoid surgery is an aerosol-generating procedure that involves the use of a high-speed drill, which produces a mixture of water, bone, blood and tissue that may contain the viable coronavirus disease 2019 pathogen. This potentially puts the surgeon and other operating theatre personnel at risk of acquiring the severe acute respiratory syndrome coronavirus-2 from contact with droplets or aerosols. The use of an additional drape designed to limit the spread of droplets and aerosols has been described; such drapes include the 'Southampton Tent' and 'OtoTent'.
To evaluate the use of a novel drape 'tent' that has advantages over established 'tent' designs in terms of having: (1) a CE marking; (2) no requirement for modification during assembly; and (3) no obstruction to the surgical visual field.
During mastoid surgery, the dispersion of macroscopic droplets and other particulate matter was confined within the novel drape 'tent'. Use of this drape 'tent' had no adverse effects upon the surgeon's manual dexterity or efficiency, the view of the surgical field, or the sterility. Hence, our findings support its use during mastoid surgery in the coronavirus disease 2019 era.
乳突手术是一种产生气溶胶的手术,涉及使用高速钻头,会产生水、骨、血和组织的混合物,其中可能含有有活力的 2019 年冠状病毒病病原体。这可能使外科医生和其他手术室人员有通过飞沫或气溶胶接触而感染严重急性呼吸系统综合征冠状病毒 2 的风险。已经描述了使用旨在限制飞沫和气溶胶传播的附加覆盖物;此类覆盖物包括“南安普顿帐篷”和“OtoTent”。
评估一种新型“帐篷”覆盖物的使用,该覆盖物在以下方面具有优于现有“帐篷”设计的优势:(1) CE 标志;(2) 组装时无需修改;以及 (3) 不阻碍手术视野。
在乳突手术期间,宏观飞沫和其他颗粒物的扩散被限制在新型“帐篷”覆盖物内。使用这种“帐篷”覆盖物对外科医生的手灵巧度或效率、手术视野的清晰度或无菌状态均无不良影响。因此,我们的研究结果支持在 2019 年冠状病毒病时代在乳突手术中使用这种“帐篷”覆盖物。
