几种防雾方法在新冠隔离病房医用护目镜中的应用效果

 

目的 探讨几种防雾方法对新冠隔离病房医务人员使用护目镜的防雾效果。方法 采用防雾喷剂（泳镜专用）法、碘酒涂抹法、洗手液涂抹法、洗洁精涂抹法4种防雾方法各处理护目镜10副，医务人员佩戴处理后的护目镜在新冠隔离病房开始一线工作，调查其工作2、4、6 h后护目镜起雾情况，比较4种方法的防雾效果。结果 4种防雾方法不同时间段起雾情况比较，差异均有统计学意义（均P<0.05）。防雾喷剂（泳镜专用）法效果欠佳，医务人员佩戴护目镜工作2 h 7副护目镜起雾，佩戴6 h 10副护目镜均起雾；碘伏涂抹法略好，医务人员佩戴护目镜工作2 h 2副护目镜起雾，佩戴6 h 7副护目镜起雾；洗手液及洗洁精涂抹法防雾效果较好，医务人员佩戴护目镜工作2 h 无护目镜起雾，佩戴6 h 分别有3、2副护目镜起雾。结论 洗手液及洗洁精涂抹法可用于医用护目镜的防雾。

Application effect of several anti-fogging methods on medical goggles in COVID-19 isolation ward

Objective To explore the anti-fogging effect of several anti-fogging methods on medical goggles. Methods Goggles were treated with four methods:anti-fogging spray (swimming goggle special use), iodophor smearing, hand sanitizer smearing, and detergent smearing, 10 pairs of goggles were treated with each anti-fogging method respectively, health care workers(HCWs) began to work in COVID-19 isolation ward after wearing treated goggles, fogging of goggles after 2, 4 and 6 hours of work was investigated, anti-fogging effect of four methods was compared. Results Fogging status of four anti-fogging methods in different periods was significantly different (all P<0.05). Anti-fogging spray method was not ideal, HCWs wore goggles for 2 hours and 7 pairs of goggles fogged, wore goggles for 6 hours and 10 pairs of goggles all fogged; iodophor smearing was slightly better, HCWs wore goggles for 2 hours and 2 pairs of goggles fogged, wore goggles for 6 hours and 7 pairs of goggles fogged; hand sanitizer and detergent smearing had better anti-fogging effect, HCWs wore goggles for 2 hours, no goggles fogged, wore goggles for 6 hours, 3 and 2 pairs of goggles fogged respectively. Conclusion Hand sanitizer and detergent smearing can be used to prevent fogging of medical goggles.
