Can the same suction catheter be used for tracheostomy tube suctioning?

Generally, it is not recommended to reuse the same suction catheter for tracheostomy tube suctioning. A new catheter should be used each time, as reusing increases the risk of infection. If in doubt, it is advised to follow sterile technique. Detailed explanation is as follows:

Suction catheters are single-use medical devices. During use, they come into contact with airway secretions and bacteria. Reusing a catheter may reintroduce residual pathogens into the airway, leading to pulmonary infection or worsening existing inflammation. Particularly in patients with tracheostomy, whose airway barriers are compromised and immunity weakened, maintaining sterility is crucial for preventing infections.

In special circumstances, if no new suction catheter is immediately available and emergency suctioning is required, the catheter may undergo strict disinfection; however, the effectiveness of such disinfection is limited, and infection risks remain. This method should only be considered a temporary emergency measure. Routine suctioning must adhere strictly to the principle of one catheter per use per patient, with immediate disposal after use to prevent cross-infection.

Strict aseptic procedures must be followed during suctioning: wear gloves and avoid hand contact with the portion of the catheter that enters the airway; select an appropriately sized catheter to ensure effective suction; perform hand hygiene before and after the procedure, and maintain a clean environment. If signs of infection such as fever or abnormal sputum occur, promptly investigate the cause and take appropriate action.
