The micro-trach. A seven-year experience with transtracheal oxygen therapy

Area of Science:

• Pulmonology
• Medical Devices
• Respiratory Medicine

Background:

• Long-term oxygen therapy (LTOT) is crucial for hypoxemic lung disease.
• Nasal oxygen delivery can be cumbersome and less efficient for some patients.
• Transtracheal oxygen delivery offers a potential alternative for improved oxygenation.

Purpose of the Study:

• To evaluate the efficacy and patient experience of micro-tracheal transtracheal catheters for LTOT.
• To compare oxygen delivery efficiency between transtracheal and nasal routes.
• To assess patient compliance and potential impact on life expectancy.

Main Methods:

• Prospective evaluation of 200 patients with hypoxemic lung disease over six years.
• Insertion of micro-tracheal transtracheal catheters for continuous oxygen delivery.
• Monitoring oxygen flow rates, patient compliance, and device functionality for 1-7 years.
• Saline instillation for catheter maintenance.

Main Results:

• Micro-tracheal transtracheal oxygen delivery (0.25-3 L/min) was equivalent to nasal delivery (1-8 L/min).
• 12.5% patient dropout rate within the first year.
• High patient compliance with 24-hour oxygen use was observed.
• The micro-tracheal catheter functions for six months between replacements without removal for cleaning.

Conclusions:

• Micro-tracheal transtracheal catheters provide an effective and convenient method for LTOT in hypoxemic lung disease.
• This delivery system may enhance patient compliance and potentially increase life expectancy, particularly for emphysema patients.
• The device's design minimizes maintenance and supports continuous, undisturbed tracheal function.
