Summary

A novel voice tracheostomy tube (VTT) allows mechanically ventilated patients to speak. This innovation maintains sufficient ventilation and prevents tracheal damage, improving patient communication.

Background:

Mechanical ventilation often necessitates tracheostomy, preventing speech.
A voice tracheostomy tube (VTT) was developed to restore vocalization in these patients.

Purpose of the Study:

To evaluate the efficacy and safety of a voice tracheostomy tube (VTT) in enabling speech during mechanical ventilation.
To assess ventilation parameters and potential complications associated with VTT use.

Main Methods:

A VTT with a specialized elastic cuff was designed to allow airflow through the glottis during expiration.
A model lung experiment assessed air leakage during inspiration and expiration.
Sixteen patients transitioned from conventional tracheostomy tubes to VTTs.

Main Results:

15 out of 16 patients could speak with the VTT without significant changes in blood oxygen (PaO2) or carbon dioxide (PaCO2) levels.
No complications were reported, and bronchoscopy confirmed no tracheal mucosa damage.
Model lung tests showed minimal inspiratory leakage and approximately 40% expiratory air diversion for vocalization.

Conclusions:

The VTT effectively enables speech in mechanically ventilated patients.
Sufficient ventilation and patient safety, including tracheal integrity, are maintained.
The VTT is a viable option even for patients with low lung compliance.
