Summary
Particle scattering increases significantly after otolaryngology examinations, posing a risk to physicians. Using personal protective equipment is crucial for otolaryngologists during patient exams to mitigate exposure to airborne particles.
Area of Science:
- Otolaryngology
- Infectious disease control
- Aerosol science
Background:
- Common otolaryngology (ear, nose, and throat) examinations are considered aerosol-generating procedures.
- Understanding particle scattering during these procedures is vital for infection control.
Purpose of the Study:
- To analyze particle scattering during standard otolaryngology examination procedures.
- To quantify aerosol and droplet production during specific ENT examinations.
Main Methods:
- 109 volunteer patients participated in the study.
- Aerosol and droplet production were measured during oropharyngeal examination, anterior rhinoscopy, rigid nasopharyngoscopy, and rigid laryngoscopy.
- Measurements were taken before and during the examinations.
Main Results:
- No significant particle scattering increase was observed during individual examination procedures compared to baseline.
- A significant increase in particle scattering across all micrometer sizes was noted at the end of all examination methods for each patient.
- Oropharyngeal examination showed higher particle increases for sizes >0.5 μm compared to other methods.
- Coughing, gagging, or sneezing during nasal endoscopy significantly increased 0.3 μm particle scattering.
Conclusions:
- Performing multiple otolaryngology examination methods together leads to a significant increase in particle scattering in the examination room.
- Otolaryngologists face significant exposure to increased particle concentrations.
- Adherence to personal protective equipment protocols is recommended for otolaryngologists during patient examinations.
