N95 Respirators

The ongoing pandemic of the novel severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has placed a substantial strain on the supply of personal protective equipment, particularly the availability of N95 respirators for frontline healthcare personnel. These shortages have led to the creation of protocols to disinfect and reuse potentially contaminated personal protective equipment. A simple and inexpensive decontamination procedure that does not rely on the use of consumable supplies is dry heat incubation. Although reprocessing with this method has been shown to maintain the integrity of N95 respirators after multiple decontamination procedures, information on the ability of dry heat incubation to inactivate SARS-CoV-2 is largely unreported. Here, we show that dry heat incubation does not consistently inactivate SARS-CoV-2-contaminated N95 respirators, and that variation in experimental conditions can dramatically affect viability of the virus. Furthermore, we show that SARS-CoV-2 can survive on N95 respirators that remain at room temperature for at least five days. Collectively, our findings demonstrate that dry heat incubation procedures and ambient temperature for five days are not viable methods for inactivating SARS-CoV-2 on N95 respirators for potential reuse. We recommend that decontamination procedures being considered for the reuse of N95 respirators be validated at each individual site and that validation of the process must be thoroughly conducted using a defined protocol.

The possibility to extend the lifespan or even reuse one-off personal protective equipment, especially for N95 respirator and surgical mask become critical during pandemic. World Health Organization has confirmed that wearing surgical mask is effective in controlling the spread of respiratory diseases in the community, but the supply may not be able to satisfy all the demands created all over the world in a short period of time. This investigation found that dry heat and UVC irradiance could effectively disinfect the mask material without creating significant damage to surgical mask.

The Impact

Abstract Introduction Preparations of health systems to accommodate large number of severely ill COVID-19 patients in March/April 2020 has a significant impact on nuclear medicine departments. Materials and Methods A web-based questionnaire was designed to differentiate the impact of the pandemic on inpatient and outpatient nuclear medicine operations and on public versus private health systems, respectively. Questions were addressing the following issues: impact on nuclear medicine diagnostics and therapy, use of recommendations, personal protective equipment, and organizational adaptations. The survey was available for 6 days and closed on April 20, 2020. Results 113 complete responses were recorded. Nearly all participants (97 %) report a decline of nuclear medicine diagnostic procedures. The mean reduction in the last three weeks for PET/CT, scintigraphies of bone, myocardium, lung thyroid, sentinel lymph-node are –14.4 %, –47.2 %, –47.5 %, –40.7 %, –58.4 %, and –25.2 % respectively. Furthermore, 76 % of the participants report a reduction in therapies especially for benign thyroid disease (-41.8 %) and radiosynoviorthesis (–53.8 %) while tumor therapies remained mainly stable. 48 % of the participants report a shortage of personal protective equipment. Conclusions Nuclear medicine services are notably reduced 3 weeks after the SARS-CoV-2 pandemic reached Germany, Austria and Switzerland on a large scale. We must be aware that the current crisis will also have a significant economic impact on the healthcare system. As the survey cannot adapt to daily dynamic changes in priorities, it serves as a first snapshot requiring follow-up studies and comparisons with other countries and regions.

Single Use

The COVID-19 pandemic, caused by severe acute respiratory syndrome coronavirus 2, has challenged healthcare providers in maintaining the supply of critical personal protective equipment, including single-use respirators and surgical masks. Single-use respirators and surgical masks can reduce risks from the inhalation of airborne particles and microbial contamination. The recent high-volume demand for single-use respirators and surgical masks has resulted in many healthcare facilities considering processing to address critical shortages. The dry heat process of 80°C (176°F) for two hours (120 min) has been confirmed to be an appropriate method for single-use respirator and surgical mask processing.

A Organização Mundial da Saúde - OMS confirmou a circulação internacional do novo Coronavírus em janeiro de 2020, nomeando-o como COVID-19 e, declarando uma pandemia. É de extrema importância que durante a pandemia, os profissionais de saúde tenham acesso e conhecimento sobre o uso correto dos Equipamentos de Proteção Individual (EPIs) e suas indicações, tomando assim, as devidas precauções na prevenção de infecções. O presente estudo buscou identificar a padronização mundial quanto ao uso dos EPIs utilizados no atendimento a pacientes suspeitos e/ou confirmados de COVID-19 no Brasil, EUA, China, Espanha, Itália e demais países europeus. Os guidelines apresentam a padronização quanto ao uso dos EPIs utilizados no atendimento a suspeitos e/ou confirmados de COVID-19, indo ao encontro das recomendações fornecidas pela OMS. Até o momento, o uso de EPIs é sem dúvida a estratégia mais importante e eficaz para proteger os profissionais de saúde durante a assistência ao paciente com COVID-19.Descritores: Infecções por Coronavírus, Equipamento de Proteção Individual, Pessoal de Saúde, Enfermagem. Recommendations for personal protective equipment to combat COVID-19Abstract: The World Health Organization - WHO confirmed the international circulation of the new Coronavirus in January 2020, naming it as COVID-19 and declaring a pandemic. It is extremely important that during the pandemic, health professionals have access and knowledge about the correct use of Personal Protective Equipment (PPE) and its indications, thus taking appropriate precautions to prevent infections. The present study sought to identify the worldwide standardization regarding the use of PPE utilized to take care of suspected and confirmed patients with COVID-19 in Brazil, USA, China, Spain, Italy and other European countries.
