常用化学消毒剂对不同材质医用手套渗透性的影响

目的了解医院常用化学消毒剂对不同材质医用手套渗透性的影响,为合理使用医用手套提供参考依据。方法采用问卷调查和染料渗透试验方法,对某省部分医院门诊医疗操作中医用手套重复使用或消毒剂消毒后重复使用的情况及手套的渗透性进行评价。结果静脉采血过程中一次性医用手套的使用率为81. 25%,不同患者之间不能做到手套一人一更换,有部分护士在对不同患者采血间隙采用消毒剂擦拭消毒手套。分别接触碘伏、苯扎溴铵或氯己定等消毒剂20～120 min后,乳胶、丁腈、PVC手套对染料的渗透性增加。结论一次性医用手套多次用消毒剂擦拭后重复使用可增加手套的渗透性,存在安全隐患。

Influence of common chemical disinfectants on the permeability of medical gloves with different materials

Objective To understand the influence of disinfectants commonly used in hospitals on the permeability of medical gloves with different materials,so as to provide reference for rational using of medical gloves.Methods The situations of reusing of disposable gloves or reusing after sterilization during medical operations in some hospitals in some province were investigated by questionnaires and dye penetration tests.Results The utilization rate of disposable gloves during venipuncture was 81.25%.The proportion of"one person,one change"during the using of gloves was 0.Some medical personnel used disinfectants to wipe gloves among different patients.After soaking in iodophor,benzalkonium bromide or chlorhexidine for 20 ~ 120 min,the permeability of latex,nitrile and PVC gloves for dyes increased.Conclusion Disposable medical gloves are reused in some hospitals.Repeated using after wiping with disinfectant can increase the permeability of gloves,which are security risk.
