安尔碘消毒液喷雾法与擦拭法皮肤消毒的效果观察

Comparison study on disinfection efficacy of Anerdian using swab and spray methods

目的探讨安尔碘消毒液喷雾法与擦拭法皮肤消毒效果。方法将30例实验对象双侧手背部皮肤分为2组，一组采用喷雾法消毒，另一组采用擦拭法消毒，对消毒前、后2组细菌培养结果进行比较，并比较2种方法的操作时间和待干时间。结果2组消毒前后菌落数组间比较差异均无统计学意义，2组的消毒合格率均达100％。喷雾法操作时间为（2．58±0．32）s明显少于擦拭法的（12．26±1．48）s，但待干时间喷雾法为（42．37±1．79）s却显著高于擦拭法的（26．24±1．46）s。喷雾法平均每例使用消毒液0．5ml，而擦拭法平均每例使用消毒液0．75ml，消耗2根棉签。结论安尔碘消毒液喷雾法与擦拭法具有相同的消毒效果，喷雾法具有操作时间短，使用消毒液量少，消毒部位有效消毒液量多，不需要使用棉签等优点，可以取代擦拭法在临床广泛推广使用，对减少医疗废物，降低医疗成本具有重要的意义。

Objective To explore disinfection efficacy of anerdian using swab and spray disinfection methods. Methods Hands of 30 subjects were randomly divided into the swab group and the spray group. The samples of before and after disinfection in each group were collected separately and observed their disinfection effect. Results The number of bacteria showed no significant difference between the two groups. The passing rate of disinfection reached 100%. The time of disinfection in the spray group was （2.58±0.32）s, significantly less than that in the swab group, （12.26±1.48）s, however, the drying time in the spray group was （42.37±1.79）s, significant longer than that in the swab group, （26.24±1.46）s. A subject hand disinfection used 0.5ml 0.2% anerdian in the spray group, and 0.75ml 0.2% anerdian and two cotton buds was used in the swab group. Conclusions There is identical disinfection efficacy between spray and swab methods. Spray disinfection method has short operating time, less use of disinfectant without using cotton buds, it is able to replace swab disinfection and will play an important role to reduce medical waste and health care costs.
