Reducing potential aerosol generation in flexible nasolaryngoscopy: a novel method

Area of Science:

• Otolaryngology
• Medical Device Development
• Infectious Disease Control

Background:

• Fibre-optic nasoendoscopy and laryngoscopy are high-risk aerosol-generating procedures.
• Transmission prevention is critical during the coronavirus disease 2019 pandemic.
• Existing protective measures require enhancement for aerosol-generating procedures.

Purpose of the Study:

• To develop and evaluate a novel patient-worn device.
• To mitigate aerosol contamination during nasoendoscopy and laryngoscopy.
• To improve safety during high-risk otolaryngological procedures.

Main Methods:

• Development of a patient-wearable device designed to contain aerosols.
• Evaluation of the device's efficacy in reducing environmental contamination.
• Assessment of the device's usability, tolerability, and cost-effectiveness.

Main Results:

• The developed device effectively reduces potential aerosol contamination.
• The device is simple to use and well-tolerated by patients.
• The device is economical to produce and implement.

Conclusions:

• The patient-worn device offers a practical solution for aerosol containment.
• It serves as an adjunct to, not a replacement for, full personal protective equipment for operators.
• Implementation can enhance safety during fibre-optic nasoendoscopy and laryngoscopy.
