Summary
This study details a successful anesthetic approach for argon plasma coagulation (APC) therapy in a patient with bronchial obstruction. The technique utilized minimal sedation via a tracheostoma, avoiding oxygen to prevent combustion risks during the procedure.
Area of Science:
- Pulmonology
- Anesthesiology
- Interventional Bronchoscopy
Background:
- Bronchial obstruction poses a significant challenge in respiratory care.
- Argon plasma coagulation (APC) is an effective endoscopic therapy for airway lesions.
- Performing APC requires careful anesthetic management due to the risk of intratracheal combustion, especially when oxygen administration is contraindicated.
Observation:
- A 54-year-old male patient with a history of left upper lobectomy, laryngectomy, and tracheotomy presented with bronchial obstruction.
- The patient underwent APC therapy via a tracheostoma under spontaneous breathing.
- Anesthesia was induced using low doses of droperidol, fentanyl, and midazolam.
Findings:
- Successful APC therapy was achieved for bronchial obstruction in a complex patient.
- The anesthetic protocol avoided oxygen administration, mitigating the risk of argon-ignited intratracheal combustion.
- The procedure was completed in 15 minutes under spontaneous air respiration through the tracheostoma.
Implications:
- This case demonstrates a safe and effective anesthetic strategy for APC therapy in patients requiring tracheostomy.
- The findings suggest that careful titration of sedative and analgesic agents can enable complex interventional procedures without supplemental oxygen.
- This approach may be applicable to other endoscopic airway interventions where oxygen use is hazardous.
