摘要目的：探讨超声震荡联合多酶液在口腔专科医院器械集中清洗中的应用效果。方法：收集2022年3月至5月温州医科大学附属口腔医院常规使用的各类器械428件，按随机数字表法将其分为对照组和试验组，每组214件，对照组采用多酶液预清洗，试验组采用超声震荡联合多酶液预清洗。比较2组清洗质量及清洗后细菌学检测合格情况。结果：试验组器械清洗后放大镜检测合格率、三磷酸腺苷荧光检测合格率及肉眼检测合格率均高于对照组（98.13% vs. 93.93%，94.39% vs. 87.38%，99.53% vs. 96.73%），差异均有统计学意义（P ＜0.05）；试验组器械清洗后即刻、30 min、2 h细菌学检测合格率均高于对照组（99.07% vs.95.79%，97.20% vs. 92.06%，92.99% vs. 86.92%），差异均有统计学意义（P ＜0.05）。结论：将超声震荡联合多酶液应用于口腔专科医院器械集中清洗，可有效清除残留物质，保障灭菌效果，提高清洗合格率。
Abstract：Objective: To explore the application effect of ultrasonic vibration combined with multi enzyme solution in centralized cleaning of instruments in stomatological hospitals. Methods: From March to May 2022,428 pieces of various instruments routinely used in Stomatological Hospital of Wenzhou Medical University were collected and divided as the control group and the test group by a random number table method, with 214 pieces in each group. The control group was pre-cleaned with multi enzyme solution, while the test group was pre-cleaned with ultrasound vibration combined with multi enzyme solution. The cleaning quality and qualified bacteriological detection after cleaning were compared between the two groups. Results: The qualified rate was higher in the experimental group after cleaning the instruments than that in the control group in magnifying glass test, adenosine triphophate fluorescence test and naked eye test (98.13% vs. 93.93%, 94.39% vs. 87.38%,99.53% vs. 96.73%) with significant difference (P<0.05). The eligible rate of bacteriological testing in the test group was higher than that in the control group immediately, 30 minutes, and 2 hours after instrument cleaning (99.07% vs. 95.79%, 97.20% vs. 92.06%, 92.99% vs. 86.92%), with significant difference (P<0.05). Conclusion:The application of ultrasonic vibration combined with multi enzyme solution in the centralized cleaning of instruments in stomatological hospitals can effectively remove residual substances, improve the cleaning qualification rate, and enhance the sterilization effect.
