A bronchoscopy is a procedure that involves examining the tracheobronchial tree for diagnostic and/or therapeutic purposes. The bronchoscope can either be flexible or rigid. Flexible bronchoscopes, which are more commonly used, have multiple ports that allow the proceduralist to visualize, suction, irrigate, and take biopsies. Spontaneous ventilation can be maintained when using a flexible bronchoscope, which affords the possibility of doing this procedure on an awake patient (although a flexible scope can also be introduced via an LMA/ETT). A rigid bronchoscope has a larger working channel, which allows for the introduction of larger instruments for grasping, sampling, or retrieving samples or foreign objects.

Labs and studies
Operating room setup
- Have bronchoscopy swivel adapter (allows bronchoscope to be inserted through ETT/LMA)
Patient preparation and premedication
- Glycopyrolate to dry the airway
- Albuterol if wheezing noted pre-operatively
- Avoid sedative premedication in elderly or patients with upper airway obstruction
- Patients with significant respiratory disease may need specialized ventilation techniques, such as jet ventilation, apnea intermittent ventilation, high-flow nasal cannula
- A plan (and backup plan) for securing the airway should be discussed with surgeon prior to induction, particularly if airway is compromised
Regional and neuraxial techniques
Intraoperative management
Monitoring and access
Induction and airway management
- If doing a GA, can use ETT or LMA
- Need large ETT (8.0 or greater) to accommodate bronchoscope
- Succinylcholine or intermediate acting NDMR
- LTA lidocaine
- If doing a MAC, have supplies ready to secure aware if needed
Positioning
- Supine
Maintenance and surgical considerations
- Consider TIVA with propofol/remifentanyl
- Avoid inhalation agents given the potential for large leaks
- Minimal use of narcotics given brevity of case
- Decadron
Emergence
Postoperative management
Disposition
Pain management
Potential complications
- Bleeding from biopsy sites
- Laryngospasm
- Breathing difficulties
- Sore throat
