4种常用保湿液对再生器械锈蚀情况的试验研究

The effect of four moisturizing liquid on reused instruments

目的采用临床常用的4种器械保湿液,比较其对手术器械的锈蚀情况。方法选用全新手术剪64把、敷料镊64把,分为生理盐水保湿组、自来水保湿组、纯水保湿组、多酶保湿组4组,各16把,观察器械的锈蚀情况。结果保湿暂存的器械随着时间延长,锈蚀的发生率提高;生理盐水组再生器械锈蚀情况较其他组严重,多酶液及纯水保湿对器械锈蚀影响较小;手术剪比敷料镊容易锈蚀;手术剪头端比手柄部容易锈蚀(P<0.05)。结论对暂存器械,需处理表面的生理盐水附着,尽量减少储存时间,使用多酶液或纯水保湿;应加强对于手术剪的防锈处理和检查保养,尤其是剪刀头部,确保临床使用器械安全。

Objective To compare the corrosive effect of four moisturizing liquid on surgical instruments. Method Sixty - four new scissors and 64 new dressing forceps were divided into four moisturizing groups of the normal saline group, the tap water group, the pure water group and the multienzyme group with 16 cases in each, and corrosive situations were observed. Results The corrosion rate of temporary moisturizing device increased with the prolonging of time, the corrosive situation of the reused instruments in the normal saline group was the worst ,the corrosive effect of the reused instruments in the multienzyme group and the pure water group were less. The operating scissors was easier to be fretted than dressing forceps, the tip was easier to be fretted than the handle of operating scissors （P 〈 0.05）. Conclusion For temporary equipments, the saline solution on the surface needs disposal, the storage time should be decreased, mul- tienzyme and pure water can be used for moisture. The anti rust treatment, inspection and maintenance should be strengthen for surgical scissors, especially the scissors tip, to ensure the equipment safety for clinical use.
