[High-frequency jet ventilation for placing tracheal stents--a case report]

Area of Science:

• Otolaryngology
• Thoracic Surgery
• Anesthesiology

Background:

• Laryngeal and tracheal stenoses pose life-threatening risks, presenting surgical challenges.
• Stent insertion is a key therapeutic option for managing these stenoses.
• High-frequency jet ventilation (HFJV) provides specific benefits in such surgical scenarios.

Observation:

• Modern HFJV systems with pressure monitoring reduce barotrauma risk, even in severe stenosis.
• Tracheal stent implantation requires temporary access to the full tracheal lumen.
• Post-operative artificial respiration must not compromise newly implanted stents.

Findings:

• A novel method utilizing tracheal HFJV enables stent implantation with brief ventilation interruptions.
• This technique ensures the airway remains patent during the procedure.
• The method prevents displacement of the newly placed tracheal stent.

Implications:

• This approach simplifies stent insertion in complex airway stenosis cases.
• It enhances patient safety by minimizing ventilation disruptions and barotrauma.
• The described technique offers a reliable solution for managing laryngeal and tracheal stenoses.
