Use sterile technique when cleaning the inner cannula. Don sterile gloves before removing the inner cannula. There is no need to suction the client before starting tracheostomy care, although the client may be preoxygenated before removing the inner cannula. A brush is used to clean the inner cannula. Hydrogen peroxide is used to clean secretions from the inner cannula, the cannula is rinsed with normal saline. Because hydrogen peroxide can be irritating to tissue, normal saline is used to clean the skin around the tracheostomy stoma.
