“…They also indicate that, often, the patient is on sedation (maybe unconscious), which means they do not fully notice what is around them. Although a couple of papers studied the effects of aerosol boxes on anxiety and performance of the medical team [ 29 , 36 ], these effects on the patient have remained a critical line of research in the future. The COVER device is effective in containing aerosols and droplets, and it is built entirely from non-medical components.…”

The emergence of the SARS-CoV-2 pandemic has imposed a multitude of complications on healthcare facilities. Healthcare professionals had to develop creative solutions to deal with resource shortages and isolation spaces when caring for COVID positive patients. Among many other solutions, facilities have utilized engineering strategies to mitigate the spread of viral contamination within the hospital environment. One of the standard solutions has been the use of whole room negative pressurization (WRNP) to turn a general patient room into an infection isolation space. However, this has not always been easy due to many limitations, such as direct access to the outdoors and the availability of WRNP units. In ER, patient and operating rooms where a patient is likely to go through aerosol-generating procedures, other solutions must be considered because most operating rooms use positive pressure ventilation to maintain sterility. The research team has designed, built and tested a Covering for Operations during Viral Emergency Response (COVER), a low-cost, portable isolation chamber that fits over a patient's torso on a hospital bed to contain and remove the pathogenic agents at the source (i.e., patient's mouth and nose). This study tests the performance of the COVER system under various design and performance scenarios using particle tracing techniques and compares its efficiency with WRNP units. The results show that COVER can dramatically reduce the concentration of particles within the room, while WRNP is only effective in preventing the room-induced particles from migrating to adjacent spaces.

“…Algunos otros autores concluyen que la caja de aerosol es clínicamente irrelevante siempre y cuando el operador se encuentre experimentado en el manejo de la vía aérea, esto en condiciones normales. 9,10,12,[22][23][24][25][26][27][28] A partir de la caja original se han realizado diversas modificaciones que han disminuido las limitaciones originalmente publicadas, recientemente Kim et al evaluaron el TI con diferentes diseños de caja de aerosoles en maniquíes con vía aérea normal y difícil, encontrando que una modificación en la caja reduce el TI, sin encontrar diferencias significativas en el TI sin caja de aerosol versus caja de aerosol modificada tanto para vías aéreas normales como difíciles, por lo que confiere beneficio protector sin retrasar el tiempo de intubación. 29 En nuestro estudio, la capacitación en ambientes simulados mejoró el tiempo de intubación, incluso comparado con la intubación sin caja, similar a lo reportado por Lima et al, que encontraron que el TI mejoró tras cinco maniobras de intubación por cada participante con caja y sin caja de aerosoles, con tiempos similares a lo reportado en nuestro estudio.…”

RESUMEN. Introducción: en la pandemia por SARS-CoV-2, la modificación de la técnica de intubación utilizando dispositivos de barrera (aerosol box) para disminuir la exposición a aerosoles generó ansiedad en los trabajadores de la salud (TS), al incrementar el grado de dificultad y el tiempo de intubación endotraqueal (TI). Los ambientes simulados de intubación incrementan la habilidad para la intubación y disminuye el TI. Objetivo: medir el TI pre y posmaniobra educativa (sin caja sin entrenamiento -SS-, con caja sin entrenamiento -CS-, con caja con entrenamiento -CC-). Material y métodos: retrospectivo, comparativo, con médicos capacitados en el ambiente simulado.

Background and Aims: The coronavirus disease 2019 (COVID-19) pandemic has initiated modified protocols for aerosol-generating procedures. A simulation study using dye was conducted to highlight contamination at intubation and extubation and to encourage adherence to the new COVID-19 protocol among anaesthesia personnel in our institution. Methods: A video demonstrating the new COVID-19 protocols was circulated in the Department of Anaesthesiology a week prior to the study. Thirty teams, each comprising an anaesthesia resident and a staff technician, were enroled. Each team was asked to demonstrate the steps of preparation, intubation and extubation on a mannequin in a COVID-19 scenario. Checklists were used to assess points of contamination and adherence to the protocols. Following debriefing, a repeat simulation was conducted. The use of a dye highlighted the points of contamination. The study subjects provided feedback on the usefulness of the session and practical difficulties encountered in adapting to the new protocols. Results: The average contamination scores decreased by 3.4 (95% confidence interval (CI): 2.4–4.4, P < 0.001) in the post-debrief session. Adherence to the steps of the modified protocol improved by a score of 2.7 (CI: 3.6–1.83) among anaesthesiologists and by 4.3 (CI: 5.3–3.3) among technicians. Further, 93% felt that the use of the colour indicator reinforced awareness of the possible points of contamination. Conclusion: Simulation with a low-fidelity mannequin by using colour indicator for secretions is an effective teaching tool to reduce health hazards during airway management in COVID-19 times.
