Anesthetic Considerations for Automated High-Frequency Jet Ventilation During Electromagnetic Navigation Bronchoscopy

Area of Science:

• Pulmonology
• Anesthesiology
• Medical Devices

Background:

• Electromagnetic navigation bronchoscopy (ENB) enhances diagnostic yield in lung biopsy.
• ENB requires minimal respiratory motion for improved accuracy.
• Current anesthetic techniques may limit the pulmonologist's maneuverability.

Purpose of the Study:

• To propose and detail an automated high-frequency jet ventilation (HFJV) technique for ENB.
• To demonstrate HFJV's ability to provide hands-free anesthesia and minimize lung movement.
• To optimize the anesthetic management for ENB procedures.

Main Methods:

• Utilized automated high-frequency jet ventilation (HFJV) via double-lumen micro jet endotracheal tubes.
• Implemented a ventilation strategy delivering consistent, very low tidal volumes.
• Focused on achieving minimal diaphragmatic and lung movement during bronchoscopy.

Main Results:

• The HFJV technique resulted in minimal chest and lung motion, without interrupting ventilation.
• This approach facilitated hands-free operation for the interventional pulmonologist.
• The method allows for a single anesthesia provider to manage the case effectively.

Conclusions:

• Automated HFJV is a viable anesthetic technique for ENB, improving navigation accuracy.
• This method enhances procedural efficiency and safety by enabling hands-free operation.
• The proposed technique supports a single-provider anesthesia model for ENB.
