In tracheostomy care, what is essential to prevent infection?

Implementing sterile technique is crucial in tracheostomy care to prevent infection because the tracheostomy site is directly exposed to the external environment, providing a potential entry point for pathogens. Maintaining a sterile field ensures that any interventions, such as suctioning or changing the dressing, do not introduce bacteria or other microorganisms into the trachea or surrounding tissues.

Using sterile instruments and supplies, along with proper hand hygiene, reduces the risk of contamination during procedures. This is particularly important since patients with tracheostomies may already be at increased risk for respiratory infections due to their compromised airway structure.

The other options do not sufficiently safeguard against infection. Non-sterile gloves may be used in some circumstances, but they are not appropriate for direct care involving the tracheostomy site. Allowing the cannula to dry out can create an environment that is favorable for microbial growth rather than ensuring cleanliness. While changing the ties frequently is important for maintaining the tracheostomy's stability, it should also be done using sterile technique to prevent any risk of infection.
