Changing a cannula, specifically the inner cannula of a tracheostomy tube, involves a straightforward process that requires careful steps to ensure patient safety and comfort. Here’s a step-by-step guide based on the provided reference:
Steps for Changing an Inner Cannula
Here's how to change the inner cannula of a tracheostomy tube:
-
Wash Your Hands: Begin by thoroughly washing your hands with soap and water or using an alcohol-based hand sanitizer. This crucial step helps prevent infection.
-
Stabilize the Neck Flange: With one hand, hold the neck flange of the tracheostomy tube steady. This prevents movement of the outer tube while changing the inner cannula, which is essential for maintaining airway stability.
-
Remove the Old Inner Cannula: Using your other hand, gently pull the used inner cannula out of the tracheostomy tube using a smooth, downward motion. Avoid jerky or abrupt movements.
-
Dispose of the Old Cannula: Immediately throw away the used inner cannula into a designated waste container. Do not reuse inner cannulas as they are single-use devices.
-
Insert a New Inner Cannula: Gently insert the new, clean inner cannula into the outer tracheostomy tube.
-
Secure the New Cannula: Make sure the new inner cannula is securely locked and correctly in place. You may hear a click or feel it lock in position. Always check to make sure it's stable before releasing your hold.
Important Considerations
- Cleanliness: Always maintain strict hygiene during the process to reduce the risk of infection.
- Smooth Movements: Use smooth and gentle movements to avoid causing any discomfort or damage.
- Proper Disposal: Dispose of used inner cannulas properly to prevent contamination.
- Check for Secure Fit: Ensure the new inner cannula is correctly locked into the tracheostomy tube to maintain proper functioning.
Table Summary
