吸唾管道两种清洁消毒方法对口腔诊室空气质量的影响

目的 口腔诊疗中含有大量细菌及病毒的气溶胶易造成周围环境及患者创口的感染,及时有效的吸唾是控制口腔诊室气溶胶污染的有效方法。本研究旨在探讨口腔门诊综合治疗台吸唾管道2种清洁消毒方法对空气质量的影响。 方法 2016年7月-2017年6月合肥市口腔医院采用2种方法清洁吸唾管道,2016年7-12月为对照组使用常规方法,2017年1-6月为实验组在对照组的基础上,第2步冲洗时增加1:200多酶清洗剂3 000 ml进行管道清洁。每月对诊室空气及吸唾器接口处进行采样,并观察吸唾管道的清洁度及异味情况。 结果 清洁消毒后,2组空气菌落数培养分别为(2.667±0.970) CFU/(皿·5 min)、(5.222±2.579) CFU/(皿·5 min),实验组低于对照组,差异有统计学意义(t=-3.934,P<0.05);吸唾器接口菌落数培养分别为(1.889±1.745) CFU/cm2、(4.667±3.125) CFU/cm2,实验组低于对照组,差异有统计学意义(t=-3.293,P<0.05);吸唾软管清洁度、异味程度结果比较,实验组优于对照组,差异有统计学意义(χ2=10.395,P<0.05)。 结论 改进后清洁消毒方法能有效降低诊室空气及吸唾器接口菌落数,同时有效增加吸唾管道清洁度并降低管道异味。改进后的清洁消毒方法简单易行,取材方便且效果可靠,值得在口腔门诊推广应用。 

Influence of two cleaning and disinfection methods for salivary suction pipes on air quality in consulting room for stomatology

Objective A large number of bacteriological and viral aerosols in oral diagnosis and treatment are easy to cause the surrounding environment and the infection of the patients' wounds. The effective and timely absorption of saliva is an effective method to control aerosol pollution in oral clinic. The purpose of this study was to explore the effect of two kinds of cleaning and disinfection methods on air quality. Methods From July, 2016 to June, 2017, two methods were used to clean the pipe. July-December 2016, the routine cleaning and disinfection method was used in the control group. January-June 2017, the test group was based on the control group, during the second flush, the pipe was cleaned with 3 000 ml 1:200-multienzyme cleaning agent. The air in consulting room and the interface of the siphon was sampled a month. After the cleaning and disinfection, the cleanliness and odour of the suction pipe were observed. Results After cleaning and disinfection, the number of air colonies cultured in the two groups were as follows:(2.667±0.970)CFU/(dish·5 min), (5.222±2.579) CFU/(dish·5 min). The test group was lower than the control group, the difference was statistically significant (t=-3.934,P<0.05). The colony number of the salivary suction interface was cultured as follows:(1.889±1.745)CFU/cm2, (4.667±3.125)CFU/cm2. The test group was lower than the control group, the difference was statistically significant (t=-3.293, P<0.05). The cleaning degree and smell degree of salivary hose in the test group were better than those in the control group. The difference was statistically significant(χ2=10.395, P<0.05). Conclusion The improved cleaning and disinfection method can effectively reduce the number of bacteria in the room air and sideshow, and effectively increase the cleanliness of the suction hose and reduce the odor of the pipe. The improved clean and disinfectant method is simple and easy to use, which is convenient and reliable.
