【摘要】：目的分析口腔正畸器械消毒效果,调查医务人员手卫生情况,并探讨针对性预防措施,为临床提供借鉴。方法将医院口腔科正畸器械于消毒前后分别进行细菌培养,医护人员消毒后采用一次性擦手纸巾擦手为对照组,采用消毒干毛巾擦手为观察组,比较正畸器械消毒前后以及两组医护人员消毒前后手部细菌菌落数,数据采用SPSS14.0软件进行统计分析。结果包括细丝钳、弓丝架、冠剪、钢丝筒、持针器、橡皮链合、工具架、医疗车及抽屉在内的正畸器械消毒后细菌菌落数较消毒前明显下降,组间比较差异有统计学意义(P0.05);对照组和观察组消毒前手部细菌菌落数分别为20.4、20.4CFU/cm2;对照组和观察组消毒后手部细菌菌落数分别为207.5、2.5CFU/cm2;对照组和观察组医护人员消毒前手部细菌菌落数组间比较差异无统计学意义;消毒后手部细菌菌落数对照组明显多于消毒前,观察组明显少于消毒前,组间比较差异有统计学意义(P0.05)。结论正畸器械消毒不严格及医护人员洗手方式不正确,是诱发正畸治疗期间医院感染的重要因素;故口腔正畸治疗医院感染预防应当注重器械消毒及提高医护人员感染控制意识。
[Abstract]:Objective to analyze the disinfection effect of orthodontic instruments, investigate the hand hygiene of medical personnel, and explore the preventive measures to provide reference for clinical practice. Methods the orthodontic instruments of hospital stomatology department were cultured before and after disinfection. After disinfection, the medical staff used disposable hand wipes as the control group, and disinfected dry towels as the observation group. The number of bacteria in hand before and after disinfection of orthodontic instruments and before and after disinfection were compared. The data were statistically analyzed by SPSS14.0 software. The results showed that the bacterial colony number of orthodontic instruments, including filaments forceps, arch wire frames, crown scissors, wire tubes, needle holders, rubber chains, tool holders, medical vehicles and drawers, decreased significantly after disinfection. The number of bacterial colonies in the hands of the control group and the observation group was 20.4% CFU / cm _ 2 before disinfection respectively; the bacterial colony number of the control group and the observation group was 207.5% 2.5 CFU / cm ~ (-2) before disinfection; the number of the control group and the observation group was 207.5% ~ 2.5 CFU / cm ~ (2) before disinfection; the number of bacterial colonies in the control group and the observation group was 207.5% ~ 2.5 CFU / cm ~ (2) before disinfection, respectively. There was no significant difference between groups of bacterial colonies. After disinfection, the number of bacteria in the control group was significantly higher than that before disinfection, and the number of bacteria in the observation group was significantly lower than that before disinfection, and the difference between the two groups was statistically significant (P 0.05). Conclusion the disinfection of orthodontic instruments is not strict and the way of washing hands by medical staff is not correct, which is an important factor in inducing nosocomial infection during orthodontic treatment. Therefore, the prevention of orthodontic nosocomial infection should pay attention to the disinfection of instruments and improve the consciousness of infection control of medical staff.
