Q1: When should bronchoscopy be performed in COVID-19 patients?
Bronchoscopy indications in COVID-19 patients must be strictly limited to clinical necessity, such as aspirations, atelectasis, or airway relocation. It should not be performed routinely for diagnostic purposes alone. This restriction minimizes aerosol generation and reduces infection risk to medical staff while maintaining patient safety during respiratory care.
Q2: What personal protective equipment is required before entering a COVID-19 patient's room for bronchoscopy?
Healthcare providers must wear an FFP3 mask, protective glasses and visor, and doubled-up gloves when donning personal protective equipment before entering a patient room. This comprehensive protection is essential due to the high aerosol generation risk during bronchoscopy procedures in COVID-19 patients.
Q3: How should the team be organized for a COVID-19 bronchoscopy procedure?
The team should be minimized to essential personnel only, typically consisting of one examiner and two assistants. All required equipment must be prepared outside the patient's room before entry. This streamlined approach reduces unnecessary exposure and maintains procedural efficiency while limiting infection transmission risk.
Q4: What ventilator settings and pre-oxygenation protocol are used during COVID-19 bronchoscopy?
Patients are pre-oxygenated with an FiO2 of 1.0 before the procedure begins. Volume-controlled ventilation mode with appropriate alarms and pressure limits is selected. The ventilator is paused during bronchoscope insertion and removal. These settings optimize oxygenation while protecting the airway during the procedure.
Q5: Why are multiple specimen collectors used during COVID-19 bronchoscopy?
Three specimen collectors rather than two are obtained during COVID-19 bronchoscopy to aid diagnosis. Separate collectors are used for each lung lobe, and bronchoalveolar lavage is performed with 10 milliliters of 0.9% sodium chloride per site. This approach enables comprehensive diagnostic sampling while minimizing aerosolization during specimen collection exchanges.
Q6: What precautions should be taken when examining the airways in COVID-19 patients?
The mucous membrane in COVID-19 patients is often very fragile and vulnerable to bleeding. Pus is expected, especially with bacterial superinfection. Careful monitoring of mucous membrane fragility through gentle contact is essential throughout the procedure. Secretions must be lavaged and suctioned before advancing the bronchoscope to prevent tissue trauma.
Q7: How should specimen collectors and equipment be handled after bronchoscopy?
Specimen collectors are closed with white tops marked with laboratory stickers and placed in marked bags for virology and microbiology transport. The single-use bronchoscope and all remaining materials must be disposed of immediately. All ventilation circuit connections are checked before resuming ventilation to ensure system integrity.
