We tested the hypothesis that protein cross-contamination occurs during batch cleaning and autoclaving of a reusable extraglottic airway device, the ProSeal laryngeal mask airway. At the end of each day for 10 days, nine laryngeal mask airways that had been used for non-intra-oral surgery were cleaned and autoclaved alongside a new unused laryngeal mask airway. In addition, a new unused laryngeal mask airway underwent the same cleaning and autoclaving procedures in isolation. Protein staining was more frequently detected on the unused laryngeal mask airways that were processed by batch rather than in isolation (p < 0.01). Protein staining was detected on all unused laryngeal mask airways that were processed by batch, but none on those processed in isolation. Protein staining was more severe with the used compared with the unused laryngeal mask airways (p < 0.001). We conclude that protein cross-contamination of the laryngeal mask airway occurs during batch cleaning and autoclaving and recommend that reusable airway devices are cleaned in isolation.
我们对可重复使用的声门上气道装置——ProSeal喉罩气道在批量清洗和高压灭菌过程中发生蛋白质交叉污染这一假设进行了测试。在10天中的每一天结束时，将9个用于非口腔内手术的喉罩气道与一个新的未使用过的喉罩气道一起进行清洗和高压灭菌。此外，一个新的未使用过的喉罩气道单独进行相同的清洗和高压灭菌程序。与单独处理相比，在批量处理的未使用过的喉罩气道上更频繁地检测到蛋白质染色（p < 0.01）。在所有批量处理的未使用过的喉罩气道上均检测到蛋白质染色，但单独处理的未使用过的喉罩气道上均未检测到。与未使用过的喉罩气道相比，使用过的喉罩气道上的蛋白质染色更严重（p < 0.001）。我们得出结论，喉罩气道在批量清洗和高压灭菌过程中会发生蛋白质交叉污染，并建议对可重复使用的气道装置进行单独清洗。
