[Selection of the bronchial tube for one-lung anesthesia by multidetector-row computed tomography (MD CT) evaluation].
One-lung anesthesia is a method of anesthesia performed by inserting the tip of a bronchial tube into either the right main bronchus or the left main bronchus. The right bronchial tube is a special structure. Since the distance of the carina to the right upper lobe bronchus is short, a side hole is made to prevent blockading of the right upper lobe bronchus, and the cuff is attached aslant to it. When inserting a bronchial tube into the right main bronchus, care is required to prevent the occurrence of atelectasis though a gap in the bronchial tube. We evaluated the structure of a trachea and a bronchus using the multidetector-row computed tomography (MD CT), and tried to select the right bronchial tube most suitable for each structure. There are individual differences in the structure of a trachea and a bronchus. By creating a 3-dimensional image of a trachea and a bronchus, the structure could be easily grasped, and therefore selection of the most appropriate bronchial tube according to the structure was possible.
