The role of double-lumen endobronchial tube in operation

Double-lumen endobronchial intubation is one of the basic pulmonary isolation techniques, and it is currently the most used and most important pulmonary isolation technique. The double-lumen endobronchial intubation can completely divide the left and right main bronchus, the purpose is to isolate the bilateral lung ventilation. The functions of double-lumen endobronchial intubation are:

1. The isolation of the lungs can realize ventilation and suction on both sides of the lungs, and effectively prevent the affected side lung secretions or pus blood from contaminating the contralateral lung, such as lung lavage, lung abscess surgery, etc.;
2. Side ventilation can collapse the lung on the operating side and reduce the interference to the operating field. Not only is it convenient for surgical operations, but it can also reduce mechanical damage to the lungs caused by surgical operations;
3. Thoracic surgery, such as lung surgery, bronchial surgery, pleura surgery, and esophageal surgery, requires double-lumen endobronchial intubation for lung isolation; cardiac surgery, such as large vessel, heart, and pericardial surgery, may also use double-lumen endobronchial tube; non-cardiothoracic surgery such as spinal fusion surgery will also require double-lumen endobronchial intubation for lung isolation; in addition, first aid and rescue when severe intrapulmonary hemorrhage is used to protect the contralateral lung from bleeding and blockage, and to prevent the patient from suffocation and death And so on, it is also necessary to use a double-lumen endobronchial tube for effective lung isolation.
