摘要
目的探讨紫外线荧光检测技术在个人防护装备(PPE)教育培训中的作用研究。方法共招募陆军军医大学第一附属医院77位医护人员进行PPE培训,利用紫外线荧光示踪剂模拟工作中感染性污染物沾染情况,在其双手、胸前、腹部、双膝关节上的关键部位模拟污染,待PPE脱卸完毕,采用专业检测仪进行检查,观察并发现荧光示踪剂模拟污染物遗留在皮肤或内层工作服部位,拍照记录并分析。结果通过紫外线荧光示踪剂标记检测后发现共94处荧光示踪剂污染,来源于43位占55.8%的医护人员,主要的荧光示踪剂残留污染部位包括:左侧腹部11次占11.70%,左侧胸前9次占9.57%,左侧前臂6次占6.38%,左脚鞋面6次占6.38%,颈部6次占6.38%,右侧肩部5次占5.32%;工作年限对污染频次有一定影响,其中工作年限<6年组模拟荧光污染频次小于其余组,与11~15年组比较差异有统计学意义(t值为-3.685,P=0.001)。结论紫外线荧光标记检测技术能够科学直观、快速反馈医护人员PPE使用过程容易污染部位,量化和明确在PPE脱卸过程中的污染风险,为针对性开展PPE装备创新与技术改进,强化PPE教学培训考核督查,进一步提高医护人员个人防护水平具有重要借鉴意义。
Objective To study the role of ultraviolet fluorescence detection technology in personal protective equipment education(PPE)and training.Methods A study was designed to inspect the risk of self-contamination during PPE doffing between 77 healthcare workers.Used a fluorescent tracer slurry which put on the hands,chest,abdomen,knees to simulate the contaminations.Self-contamination of scrubs and skin was measured using ultraviolet light visualization respectively.Results According to the uv-fluorescer simulating study,43(55.8%)of the medical staff had contamination after the removal of PPE,and the main sites of contamination included:left side of the abdomen 11(11.70%),left side of the chest 9(9.57%),left forearm 6(6.38%),left foot instep 6(6.38%),neck 6(6.38%),right shoulder 5(5.32%),etc.Among them,the frequency of simulated fluorescence pollution in the group with working years less than 6 years was less than that in the other groups,and the difference was statistically significant compared with the group of 11-15 years(t value was-3.685,P value was 0.001).Conclusion Ultraviolet fluorescence labeling detection technology can directly,quickly and effectively evaluate and feedback the key contaminated parts in the process of using PPE,which can provide detailed evidence for redesigning PPE and improve the PPE training process to reduce the contamination.
