新型冠状病毒肺炎疫情期间应对高强度护理工作的护目镜防雾方法比较研究

A comparative study on the anti-fog methods of protecting goggles in high intensity nursing work during corona virus disease 2019 epidemic

目的比较新型冠状病毒肺炎(简称新冠肺炎)疫情期间高强度护理工作中3种试剂对护目镜的防雾效果。方法选择东南大学附属中大医院急诊科2020年2月21日至26日参与新冠肺炎疑似患者护理治疗的199名工作人员作为研究对象,将使用碘伏(碘伏涂抹组)、石蜡油(石蜡油涂抹组)、灭菌注射用水(灭菌注射用水涂抹组)涂抹的护目镜每日随机分配给工作人员佩戴。记录3组工作人员佩戴护目镜后起雾时间和因雾取下时间;并发放调查问卷,调查工作人员对镜面模糊、眼部和皮肤刺激以及对工作影响程度的主观评价。结果碘伏涂抹组护目镜起雾时间和取下时间均较石蜡油涂抹组和灭菌注射用水涂抹组明显延长〔护目镜起雾时间(min):30.0(8.0,90.0)比10.0(3.5,17.5)、10.0(5.0,20.0),护目镜取下时间(min):120.0(50.0,170.0)比30.0(12.5,59.0)、30.0(15.0,60.0),均P<0.05〕;石蜡油涂抹组与灭菌注射用水涂抹组护目镜起雾时间和取下时间比较差异均无统计学意义(均P>0.05)。3组初始模糊程度、对眼部和皮肤的刺激情况比较差异均无统计学意义(均P>0.05)。碘伏涂抹组对工作影响主观评分明显低于石蜡油涂抹组和灭菌注射用水涂抹组〔分:3.0(2.0,5.0)比5.0(3.0,6.0)、5.0(4.0,7.0),P<0.05〕。结论碘伏涂抹方法可起到良好的防雾效果,并在镜面模糊、对眼部和皮肤刺激方面与另外两种防雾剂无区别,同时对工作影响最小,是一种使用可靠、容易取得、值得推广的护目镜防雾剂。

Objective To compare the anti-fog effect of three reagents used on goggles in high-intensity nursing work during corona virus disease 2019(COVID-19)epidemic.Methods A total of 199 staff members who participating in the treatment of suspected patients diagnosed with COVID-19 from February 21 to 26,2020 in the emergency department of Zhongda Hospital Affiliated to Southeast University were selected as research objects and randomly assigned with one of three types of goggles,which were smeared with iodophor(iodophor smeared group),paraffin oil(paraffin oil smeared group),and sterilized injection water(sterilized injection water smeared group).The fogging time and goggles removal time were recorded.Questionnaire was sent out to collect the results of subjective evaluation of mirror blurring,eyes and skin irritation and working convenience as well.Results In iodophor smeared group,the fogging time and goggles removal time was significantly longer than that in paraffin oil smeared group and sterilized injection water smeared group[fogging time(minutes):30.0(8.0,90.0)vs.10.0(3.5,17.5),10.0(5.0,20.0),removal time(minutes):120.0(50.0,170.0)vs.30.0(12.5,59.0),30.0(15.0,60.0),both P<0.05].There were no statistical differences between paraffin oil smeared group and sterilized injection water smeared group in terms of fogging time and goggles removal time(both P>0.05).There were no significant differences among the three anti-fog methods in terms of initial mirror blurring,eyes and skin irritation(all P>0.05).The subjective score of iodophor smeared group was significantly lower than that of paraffin oil smeared group and sterilized injection water smeared group[points:3.0(2.0,5.0)vs.5.0(3.0,6.0),5.0(4.0,7.0),P<0.05].Conclusion The iodophor application is a convenient method with good results on goggles regarding anti-fog,without significant difference in mirror blurring,eyes and skin irritation compared with other two methods.Iodophor is a reliable and easy-access anti-fog material that is worth promoting.
