Background technique

With the development of thoracic surgery, one-lung ventilation has been continuously improved and perfected. The purpose of one-lung ventilation is to prevent secretions or blood from the operated side lung from entering the healthy side lung, to ensure unobstructed airway, and to prevent cross-infection and spread of pathogens. , to avoid expansion of the surgical side, which is beneficial to the surgical operation and reduces damage to the lung parenchyma.

There are three main types of one-lung ventilation tools currently in use: single-lumen bronchial catheters, double-lumen bronchial catheters, and bronchial catheter occluders. The latter is divided into single-lumen bronchial catheter occluder and double-lumen bronchial catheter occluder. The double-lumen bronchial catheter occluder is the latest one. There are fixed bifurcations at the front of the occluder. There are two inflatable airbags of different colors at both ends. On both sides of the tracheal carina, which side of the lung is to be blocked, the air sac on that side is filled with air to collapse the lung on that side. To ensure the smooth progress of one-lung ventilation. Using this occluder, the operation is simpler and easier to control, and there is no fear of displacement of the occluding air bag during the operation, which significantly improves the success rate of the lung isolation technique. However, there is only one situation that may lead to the failure of using this kind of occluder, that is, the carina is too wide, so that the fixed bifurcated cuffs on both sides cannot ride on the carina, or become straight, or skewed side, making the blockage fail.
