UNASSIGNED: An electronic questionnaire was established and administered through WeChat, and a cross-sectional survey was conducted to determine SM use duration and related discomfort of operating room medical staff. Then, operating room anesthesiologists were enrolled in a single-arm study. Peripheral blood oxygen saturation (SpO2), heart rate, and respiratory rate were determined at different times before and after SM use. Shortness of breath, dizziness, and headache were subjectively assessed based on the visual analog scale (VAS) scores.
UNASSIGNED: In total, 485 operating room medical staff completed the electronic questionnaire; 70.5% of them did not change SMs until after work, and 63.9% wore SMs continuously for more than 4 h. The proportion of anesthesiologists was the highest. After wearing masks for 4 h, the shortness of breath, fatigue, and dizziness/headache rates were 42.1, 34.6, and 30.9%, respectively. Compared with other medical staff, the proportion of subjective discomfort of anesthesiologists increased significantly with prolonged SM use from 1 to 4 h. Thirty-five anesthesiologists completed the study. There was no difference in anesthesiologist SpO2, heart rate, or respiratory rate within 2 h of wearing SMs. After more than 2 h, the variation appears to be statistically rather than clinically significant-SpO2 decreased (98.0 [1.0] vs. 97.0 [1.0], p < 0.05), respiratory rate increased (16.0 [3.0] vs. 17.0 [2.0], p < 0.01), and heart rate remained unchanged. As mask use duration increased, the VAS scores of shortness of breath, dizziness, and headache gradually increased.
UNASSIGNED: In healthy anesthesiologists, wearing SMs for more than 2 h can significantly decrease SpO2 and increase respiratory rates without affecting heart rates.
UNASISIGNED:通过微信建立和管理电子问卷,并进行横断面调查,以确定手术室医务人员SM的使用时间和相关不适.然后,手术室麻醉师参加了一项单臂研究.外周血氧饱和度(SpO2),心率,在SM使用前后的不同时间测定呼吸频率。呼吸急促,头晕,和头痛根据视觉模拟量表(VAS)评分进行主观评估.
未经批准:总共,485名手术室医护人员填写了电子问卷;70.5%的医护人员直到下班后才更换SM,63.9%的人连续佩戴SMs超过4小时。麻醉医生的比例最高。戴口罩4小时后,呼吸急促,疲劳,头晕/头痛率分别为42.1、34.6和30.9%,分别。与其他医务人员相比,随着SM长期使用1~4h,麻醉医师主观不适的比例显著增加。35名麻醉医师完成了这项研究.麻醉师SpO2,心率,或佩戴SM后2小时内的呼吸频率。超过2小时后,变化似乎在统计学上而不是临床上显著-SpO2降低(98.0[1.0]vs.97.0[1.0],p<0.05),呼吸频率增加(16.0[3.0]vs.17.0[2.0],p<0.01),心率保持不变。随着面罩使用持续时间的增加,呼吸短促的VAS评分,头晕,头痛逐渐加重。
未经授权:在健康的麻醉师中,佩戴SMs超过2h可以显着降低SpO2并增加呼吸频率,而不影响心率。
