Summary
Serious complications from transtracheal high-frequency jet ventilation (HFJV) are rare. This study found subcutaneous emphysema and pneumothorax as the most common issues in 643 patients undergoing airway surgery.
Area of Science:
- Anesthesiology
- Pulmonology
- Otolaryngology
Background:
- Serious complications during high-frequency jet ventilation (HFJV) are uncommon, typically seen in patients with difficult airways.
- Previous data on HFJV complications come from animal studies or limited case reports.
Purpose of the Study:
- To prospectively evaluate the complications associated with transtracheal high-frequency jet ventilation (HFJV).
- To assess the safety and reliability of transtracheal HFJV in a large patient cohort undergoing laryngeal procedures.
Main Methods:
- A prospective multicentre study involving 643 patients undergoing laryngoscopy or laryngeal laser surgery.
- Data collection focused on the incidence and nature of complications related to transtracheal catheter insertion and ventilation.
Main Results:
- Transtracheal catheter insertion failure occurred in 0.3% of patients.
- Subcutaneous emphysema was observed in 8.4% of cases, particularly after multiple tracheal punctures.
- Pneumothorax occurred in 1% of patients, with some cases linked to laser injury or difficult laryngoscopy.
- Arterial desaturation was more frequent during laser surgery and in overweight individuals.
Conclusions:
- Transtracheal HFJV is a reliable method for experienced users when employing a ventilator with an automatic cut-off device.
- While airway pressure control is important, it does not entirely eliminate the risk of pneumothorax.
