Reducing airborne transmissible diseases in perioperative environments.

Area of Science:

• Medical Science
• Infectious Disease Epidemiology
• Occupational Health

Background:

• The COVID-19 pandemic underscored the threat of aerosol transmissible diseases, particularly in healthcare settings.
• Anaesthesia providers face prolonged exposure risks in operating rooms due to close proximity and limited ventilation.
• Standard surgical masks offer minimal protection against airborne pathogens in these environments.

Discussion:

• Despite recent pandemic experiences, a comprehensive understanding of operating room aerosol transmission risks remains elusive.
• Enhanced ventilation alone is insufficient to mitigate risks associated with close, prolonged exposure.
• Surgical patients are also vulnerable to airborne viral and bacterial contaminants.

Key Insights:

• Hospitals can implement immediate protective measures, including routine respirator use for staff.
• Establishing clear protocols and triggers for respirator use is crucial.
• Educating healthcare workers on aerosol transmissible disease prevention is essential.

Outlook:

• Routine provision and utilization of respirators can significantly enhance protection.
• Portable air purifiers can improve air quality in under-ventilated perioperative areas.
• Further research is needed to fully elucidate and mitigate operating room aerosol transmission risks.
