The purpose of double lumen endobronchial tube
 
The purpose of double-lumen endobronchial tube is to isolate and ventilate the airways of the healthy lung and the diseased lung, and also prevent the sputum or blood from the affected lung from flowing to the unaffected lung to achieve good lung isolation and prevent cross-infection and The purpose of preventing the spread of germs can also avoid lung expansion on the surgical side, which is conducive to the smooth progress of the operation.

During the process of intubation of double lumen endobronchial tube, the anesthesia should not be too shallow, so as to avoid accidents caused by the slippage of the catheter or the occurrence of coughing. When changing the position of the patient, be careful not to tilt the patient's head excessively back. Patients undergoing double-lumen bronchial catheter intubation should be given pure oxygen inhalation. If the oxygen saturation drops after intubation, relevant treatment should be carried out in time to stop sputum suction or withdraw the tube to the main bronchus. After extubation, care should be taken to keep the airway unobstructed, and given a semi-sitting position, while nursing the patient to perform deep breathing exercises, and instructing the patient to effectively expectoration to prevent atelectasis.
