摘要

目的

对比不同牙科手机清洗与干燥技术联合应用的效果，确定最优再处理方案，保障器械处置质量与临床使用安全。

方法

选取2024年3月我院使用的牙科手机800件，分别采用喷淋清洗消毒+压力气枪干燥（喷淋+气枪组）、喷淋清洗消毒+低温真空干燥（喷淋+真空组）、减压沸腾清洗消毒+压力气枪干燥（沸腾+气枪组）、减压沸腾清洗消毒+低温真空干燥（沸腾+真空组）处理，每组200件。比较4组牙科手机的清洗效果、干燥效果、灭菌后油性湿包情况以及工作人员对4组处理方案的操作满意度。

结果

沸腾+气枪组与沸腾+真空组牙科手机目测合格率及蛋白残留定量检测合格率均高于喷淋+气枪组、喷淋+真空组（

0.05）。4组牙科手机清洗消毒后干燥合格率比较，差异无统计学意义（

0.05）；喷淋+真空组、沸腾+真空组牙科手机清洗消毒后额外器械干燥合格率显著高于喷淋+气枪组、沸腾+气枪组（

0.05）。喷淋+真空组、沸腾+真空组牙科手机油性湿包发生率显著低于喷淋+气枪组、沸腾+气枪组（

0.05）。工作人员对沸腾+真空组的操作满意度最高（

0.01）。

结论

采用减压沸腾清洗消毒联合低温真空干燥技术处理牙科手机，既可有效保证清洗及灭菌质量，又可实现消毒供应中心高效处理复用医疗器械的工作目标，工作人员对此处理方案的操作满意度较高。

Abstract

Objective

To compare the effects of combined application of different cleaning and drying technologies for dental handpieces， determine the optimal reprocessing scheme ， and ensure the quality of instrument reprocessingt and clinical safety.

Methods

A total of 800 dental handpieces used in our hospital in March 2024 were selected and equally divided into four groups with 200 pieces per group： spray cleaning and disinfection combined with compressed air gun drying group （spray+air gun group）， spray cleaning and disinfection combined with low-temperature vacuum drying group （spray+vacuum group）， depressurized boiling cleaning and disinfection combined with compressed air gun drying group （boiling+air gun group）， depressurized boiling cleaning and disinfection combined with low-temperature vacuum drying group （boiling+vacuum group）. The four groups were compared in terms of cleaning effect， drying effect， incidence of oily wet packs after sterilization， and staff´s operational satisfaction with the four processing scheme.

Results

The qualified rates of visual inspection and quantitative detection of protein residues of dental handpieces in the boiling+air gun group and boiling+vacuum group were higher than those in the spray+air gun group and spray+vacuum group （

0.05）. There was no statistically significant difference in the drying qualified rates of dental handpieces after cleaning and disinfection among the four groups （

0.05）. The qualified rates of supplementary mechanical drying of dental handpieces after cleaning and disinfection in the spray+vacuum group and boilin

g+vacuum group were significantly higher than those in the spray+air gun group and boiling+air gun group （

0.05）. The incidences of oily wet packs after sterilization in the spray+vacuum group and boiling+vacuum group were significantly lower than those in the spray+air gun group and boiling+air gun group （

0.05）. The boiling+vacuum group obtained the highest staff´s operational satisfaction （

0.01）.

Conclusion

Adopting depressurized boiling cleaning and disinfection combined with low-temperature vacuum drying technology for dental handpieces can effectively guarantee cleaning and sterilization qualities， enable the goal of efficient reprocessing of reusable medical devices in central sterile supply department， and achieve the high staff´s operational satisfaction with the processing protocol.
