[Present role of selective intubation sounds in thoracic surgery]

After the indications for selective bronchial intubation, the methods of bronchial control by various techniques, together with their advantages and disadvantages, are discussed. A Advantages: -the right and left lungs are completely separated and if the tube is correctly placed in position, it will avoid any loss of secretions towards the healthy lung; -the lungs may be ventilated together or separately; -there is perfect water tightness within the traches and bronchi; -rapid deflation or inflation of each may be obtained without modifying the position of the tube. B Disadvantages: -there is an increased resistance to the air flow if only one lung is ventilated; -alone, a small diameter aspiration catheter may be used; -the catheters are costly, they may be difficult to introduce in small size subjects.
