“…Human to human transmission occurs via droplets which come out of an infected person's mouth after sneezing and coughing as well as direct contact to infected person (Guo et al, 2020;Yuen et al, 2020;Cai et al, 2020). Eyes are also route of virus entry in the body (Yu et al, 2020;Douglas and Douglas, 2020). However, in a study it was seen that infected pregnant ladies of third trimester had delivered the normal children.…”

“…Among the simple methods to prevent fogging of the eyewear, a variety of methods including the application of surfactant liquid, converting the eyewear to a filtered eye mask by creating vents sealed with N95 mask cutting and use of anti-fog glasses or anti-fog coating have been described. 6 , 9 , 12 , 13 However, the actual effectiveness of these methods which perform the operative procedures remains unknown. We tested three inexpensive modifications on a disposable sealed poly-hydrocarbon based protective eyewear and found that the detergent-based liquid surfactant was effective in maintaining the workable vision for as long as 2 h. The PET material based anti-fog film although prevented fogging for long but failed to provide the workable vision required for a simulated surgical task.…”

“…The currently recommended protective eyewears to prevent the exposure of the eye to aerosol or airborne particles are hermetically sealed eyewears. 8,9 With no space for outer air circulation and increased perspiration of skin in a closed cavity, the risk of fogging increases. Additionally, with the recommended operating room conditions in COVID times, i.e, temperature between 24 and 30 C and humidity between 30 and 70%, and also with the orthopedic procedures requiring exertion, the perspiration increases, resulting in excessive fogging.…”

“… 11 Therefore, a low-cost modification of the hermetically sealed protective eyewear that can prevent fogging is desirable in the current times. Plastic films such as polyethylene terephthalate (PET) with surface modifications, 12 surfactant sprays, 6 , 13 and addition of N95 mask cutting to the air vents of the sealed eyewear 9 are some attractive low-cost modifications to prevent fogging of the viewing frames. However, their effectiveness in a real surgical scenario or a simulated operating room environment with the aforestated modified parameters has not been tested.…”

In the current COVID pandemic, hermetically sealed eyewear is recommended for safe surgical practices to prevent eye contact with contaminated airborne particles or aerosols. These sealed eyewears definitely reduce the risk of contamination of eyes. However, there is a constant issue of fogging up of the inner surface that prevents good surgical visibility which can impair surgeons' performance and their ability to perform fine tasks, especially in operating rooms with temperature and humidity controlled as per the COVID guidelines. We investigated the effectiveness of surface-modified anti-fog polyethylene terephthalate(PET) films and the application of a detergent-based surfactant liquid, applied to the inner aspect of viewing frame, and addition of filtered vents in the prevention of fogging up of the protective eyewears in a simulated operating room environment. Methods: Ten volunteer orthopedic surgeons tested three modifications of a poly-hydrocarbon based hermetically sealed eyewear as a) application of a surface-modified anti-fog PET film on the inner aspect of eyewear, b) application of a detergent-based surfactant coating on the inner aspect of the protective eyewear, and c) addition of two filtered vents/holes on each side of the protective eyewear, covered with an N95 mask cutting. The testing was performed while completing a synthetic bone-based surgical task in a simulated operating room environment of 24e26 temperature and humidity between 40 and 70%, for a maximum of 2 h. The duration to the loss of clear visibility (ability to read a newspaper) and workable visibility (ability to perform the surgical task) was recorded for each volunteer. Results: The detergent-based surfactant provided the longest duration of clear visibility (69.3 ± 8.16 min) and the workable visibility was maintained for more than 2 h. The second best durations of clear visibility (31.9 ± 3.75 min) and workable visibility (41.6 ± 5.39 min) were provided by the surface-modified anti-fog PET film. The addition of the filtered vents provided only a marginal improvement in the visibility. Conclusion: A detergent-based surfactant coating of the viewing surface provides a simple, inexpensive and effective solution to the problem of fogging of the protective eyewears. Besides this, the workable vision is maintained for a prolonged duration.

“…Discomfort caused by hydrocolloids can also be avoided by using a viscose peel agent. [37,38] Application of these strategies to the protective equipment of current COVID-19 frontline nurses can reduce their discomfort, thereby increasing their psychological health, and their abilities to tend to their patients.…”

Objective: This study explores the psychological experiences and factors affecting the psychological health of isolation ward nurses during the COVID-19 pandemic in China. Findings from this study will inform on future initiatives that can support frontline nurses, improve their ability to cope with public health emergencies, and create effective nursing management strategies.Methods: A qualitative phenomenological research method was applied. In-depth interviews with 10 first-line clinical nurses in isolation wards during the COVID-19 pandemic were conducted. Collected data were analyzed with the Colaizzi seven-step analysis method.Results: Three themes were emerged, including the evolution of the psychological health of nurses, positive factors that affect psychological health, and negative factors that affect psychological health. Nurses experienced various changes to their psychological health during the pandemic. When nurses were supported by team members, appreciated by their patients, and cared for by their organizations, their psychological health was enhanced. When nurses felt disconnected from their families and experienced physical discomfort due to protective equipment, their psychological health was negatively impacted.Conclusions: Changes in the psychological health of isolation ward nurses should be constantly monitored. Proper strategies should be implemented to reduce the physical discomfort experienced by nurses due to protective equipment, increase perceptions of familial and workplace support, and determine ways to increase displays of patient appreciation for nursing work.
