Official Title
The Comparison of Level of Aerosol Particle at the Face Level of Endoscopist Performing Upper Gastrointestinal Endoscopy in Patients With and Without Head Box; a Randomized Control Trial
Brief Summary

According to preexisting data, it has revealed the fundamental role that aerosols play in the transmission of the COVID-19 virus. Esophagogastroduodenoscopy (EGD), producing particle smaller than 5 microns, was regarded as 'aerosol-generating procedures' (AGPs) associated with an increased risk of transmission of respiratory pathogens to healthcare workers. The strategies aim to reduce spreading of aerosol during the procedure should be beneficial. Using an acrylic box to cover the head of a patient undergoing an endoscopy seems to reduce aerosol scatter and reduce the spread of respiratory pathogens. At present, there are no high-quality studies that provide quantitative data on the use of head box to reduce aerosol generation.

Detailed Description

Pandemic of coronavirus disease 2019 (COVID-19) caused by severe acute respiratory syndrome
coronavirus 2 (SARS-CoV-2) affected globally clinical practice including temporary
postponement of elective endoscopic procedures in GI office activity and has caused an
unprecedent concern in personal protection against the airborne virus. Whitin 2.5 years since
the outbreak in mid-December 2019, COVID-19 had infected over 182 million people and killed
more than 3.9 million across 210 countries worldwide. (Ref.
https://www.who.int/emergencies/diseases/novel-coronavirus-2019).

According to preexisting data, it has revealed the fundamental role that aerosols play in the
transmission of the COVID-19 virus. Previously, in the medical community attempted to find
strategies to minimize risk of respiratory transmission to HCPs during pandemic such as
wearing either standard or full personal protective equipment (PPE), including do-it-yourself
devices and gadgets are the necessary substitutes to protect them from aerosolization.
However, there has been no published study evaluating the efficacy or real benefit of these
tools in preventing aerosolization during EGD quantitatively.

Esophagogastroduodenoscopy (EGD), producing particle smaller than 5 microns, was regarded as
'aerosol-generating procedures' (AGPs) associated with an increased risk of transmission of
respiratory pathogens to healthcare workers. The strategies aim to reduce spreading of
aerosol during the procedure should be beneficial.

Using an acrylic box to cover the head of a patient undergoing an endoscopy seems to reduce
aerosol scatter and reduce the spread of respiratory pathogens. At present, there are no
high-quality studies that provide quantitative data on the use of head box to reduce aerosol
generation.
