OBJECTIVE
During the coronavirus disease 2019 (COVID-19) pandemic, the N95 mask is an essential piece of protective equipment for healthcare workers. However, the N95 mask may inhibit air exchange and odor penetration. Our study aimed to determine whether the use of N95 masks affects the odor discrimination ability of healthcare workers.
METHODS
In our study, all the participants were asked to complete three olfactory tests. Each test involved 12 different odors. The participants completed the test while wearing an N95 mask, a surgical mask, and no mask. The score for each olfactory test was documented.
RESULTS
The olfactory test score was significantly lower when the participants wore N95 masks than when they did not wear a mask (7 10, < 0.01). The score was also lower when the participants wore N95 masks than surgical masks (7 8, < 0.01).
CONCLUSION
Wearing N95 masks decreases the odor discrimination ability of healthcare workers. Therefore, we suggest that healthcare workers seek other clues when diagnosing disease with a characteristic odor.
目的
在 2019 冠状病毒病（COVID-19）大流行期间，N95 口罩是医护人员的基本防护设备。然而，N95 口罩可能会抑制空气交换和气味渗透。我们的研究旨在确定 N95 口罩的使用是否会影响医护人员的气味辨别能力。
方法
在我们的研究中，所有参与者都被要求完成三项嗅觉测试。每项测试都涉及 12 种不同的气味。参与者在佩戴 N95 口罩、外科口罩和不戴口罩的情况下完成测试。记录每项嗅觉测试的得分。
结果
参与者佩戴 N95 口罩时的嗅觉测试得分明显低于不戴口罩时（7 10，<0.01）。参与者佩戴 N95 口罩时的得分也低于外科口罩（7 8，<0.01）。
结论
佩戴 N95 口罩会降低医护人员的气味辨别能力。因此，我们建议医护人员在诊断具有特征性气味的疾病时寻求其他线索。
