Double lumen bronchial tube type: left type, right type
Specifications of double-lumen bronchial tube: Fr26, Fr28, Fr31, Fr32, Fr33, Fr35, Fr37, Fr39, Fr41
A double-lumen bronchial tube is inserted into the left or right bronchus to confirm that the airway is clear in the left or right lung.
A double-lumen bronchial tube temporarily separates ventilation in the left and right bronchus and isolates the airways in the healthy and diseased lungs. It can not only inhale anesthetic gas through bilateral lumen, but also use only healthy lumen for anesthesia and ventilation. It can also absorb secretions at any time, and it can prevent sputum or blood flow from diseased lungs to healthy lungs, thus achieving good lung isolation.
The rational use of double-cavity bronchial cannula can prevent cross infection and spread of bacteria, and also can avoid the expansion of the lung on the operating side, which is conducive to the smooth operation.
What are the indications of double lumen bronchial intubation?
The indications of double-lumen bronchial intubation are mainly the diet of tracheal, bronchial and lung tumors, which leads to the symptoms of tracheobronchial foreign body. This includes respiratory insufficiency, the need for artificial ventilator, airway protection and endotracheal intubation during general anesthesia.
Precautions for double-lumen bronchial intubation
1, anesthesia should not be too shallow;
2. When helping patients to change their position, the head should not be tilted back too much;
3. Double-lumen bronchial intubation requires pure oxygen inhalation;
4. If blood oxygen saturation decreases during intubation, relevant treatment should be carried out in time;
5. After extubation, the respiratory tract should be kept unobstructed, and the patient should be in the semi-seated position;
6. Patients should carry out deep breathing exercises to guide patients to effectively cough up phlegm and avoid atelectasis.
