Summary
Percutaneous dilatational tracheotomy (PDT) can cause tracheal ring fractures and destruction, especially with longer cannulation. Improvements to the PDT technique are needed to prevent these serious airway complications.
Area of Science:
- Medical research
- Surgical pathology
- Anatomy
Background:
- Percutaneous dilatational tracheotomy (PDT) is a common procedure.
- Potential complications of PDT include damage to the trachea.
- Understanding the extent of tracheal damage is crucial for patient safety.
Purpose of the Study:
- To investigate the macroscopic and microscopic pathological changes in the tracheas of patients following PDT.
- To correlate tracheal damage with the duration of cannulation.
- To identify potential improvements in the PDT technique to mitigate complications.
Main Methods:
- Autopsy analysis of 12 tracheas from patients who underwent PDT.
- Macroscopic and microscopic examination of tracheal tissues.
- Evaluation of tracheal ring integrity, puncture site, and lumenal changes.
Main Results:
- Fractures of one or more tracheal rings were observed in 11 out of 12 patients.
- Tracheal ring destruction was present in all 8 patients cannulated for over 10 days (p<0.005).
- Two patients exhibited anterior wall protrusion leading to tracheal stenosis.
Conclusions:
- PDT is associated with significant tracheal ring damage, including fractures and destruction.
- Duration of cannulation is a key factor in the severity of tracheal ring destruction.
- Modifications to the PDT technique may help reduce the incidence of these complications.
