The Montgomery tracheal cannula: radiological assessment
Journal of the Canadian Association of Radiologists
|March 1, 1985
Summary
The Montgomery silicone tracheal cannula offers an alternative airway for specific conditions like obstructive sleep apnea. Evaluation showed one patient had respiratory issues due to improper cannula positioning.
Area of Science:
- Medical Devices
- Respiratory Medicine
- Surgical Technology
Background:
- The Montgomery silicone tracheal cannula is an emerging airway device.
- It is utilized in specific clinical scenarios as an alternative to traditional tracheostomy tubes.
- Its application includes managing conditions such as obstructive sleep apnea.
Purpose of the Study:
- To assess the positioning of the Montgomery silicone tracheal cannula in patients.
- To identify any potential complications related to cannula placement.
- To evaluate imaging techniques for visualizing the cannula.
Main Methods:
- The study involved four patients requiring the Montgomery silicone tracheal cannula.
- Cannula position was assessed using conventional or xeroradiographic lateral neck views.
- Lateral tomography was employed for visualization, particularly in an obese patient.
Main Results:
- Improper positioning of the cannula was identified in one patient.
- This malpositioning led to respiratory difficulties for the affected patient.
- Lateral tomography proved beneficial for visualizing the cannula in an obese individual.
Conclusions:
- The Montgomery silicone tracheal cannula requires careful placement to avoid respiratory complications.
- Radiographic evaluation, including lateral tomography, is crucial for confirming correct positioning.
- This device may require specific imaging considerations, especially in patients with obesity.
