How frequently should tracheal cannula be replaced?

Update Date: 2024-06-19 Source: Network

For patients with long-term tracheotomy, the tube core is replaced 2 to 3 times a day, and the cannula is generally replaced once a month. This situation may be due to infection or fungal infection. It is recommended to further examine at the ENT outpatient department.

Indications:

1. Laryngeal obstruction: severe laryngeal obstruction caused by laryngeal inflammation, tumors, trauma, foreign bodies, etc.

2. Retention of lower respiratory tract secretions: retention of lower respiratory tract secretions caused by various reasons (such as craniocerebral trauma, chest and abdominal trauma, and poliomyelitis). In order to aspirate sputum and maintain airway patency, tracheotomy can be considered.

3. Preventive tracheotomy: pharyngeal tumors, abscesses with dyspnea; for certain major surgeries of the oral cavity, nasopharynx, maxillofacial, pharynx, and larynx, tracheotomy can be performed to prevent blood flowing into the lower respiratory tract during and after surgery, maintain postoperative respiratory tract patency, and prevent postoperative bleeding or local tissue swelling that may obstruct breathing.

4. Removal of tracheal foreign bodies: When endoscopic forceps removal is unsuccessful, and it is estimated that there is a risk of asphyxia in further attempts, or when there is no equipment and technology for tracheal endoscopy, the foreign body can be removed through tracheotomy (rare).

Postoperative Care Methods:

1. Adjust the tightness of the cannula strap at any time.

2. Closely observe the respiratory status to ensure smooth airflow. Do not cover the cannula with bedding; wipe away secretions coughed out of the cannula at any time. Regularly administer intratracheal drops or nebulization. Wet the cannula mouth with physiological saline and a single layer of gauze.
