Accurate placernent of double-lumen endobronchial tube is essential for successful one lung anesthesia We studied 58 adult patients (38 males and 20 females) undergoing thoracic surgery under one lung anesthesia. We used the fiberoptic bronchoscope as an "introducer" over which the double lumen tube was advanced under direct vision. Correct position of the left side double-lumen endobronchial tube at supine position was determined by direct vision of cephalad surface of the bright blue bronchial cuff immediately below the carina. Correct position of the right side double lumen endobronchial tube at supine position was determined by direct vision of the right upper lobe bronchial orifice through the right upper labe ventilation slot. After the patient was repositioned, the position of the double lumen endobronchial tube was rechecked by fiberoptic bronchoscope.
The results were as follows; 1) There was a significant correlation of correct depth of left and right double lumen endobronchial tube at supine position with height for both male and female patients. 2) Left side double lumen endobronchial tube: 58% of total cases (20 Case of 38 Case) were displaced by turning of the patient from supine to the lateral decubitus position. 3) Right side double lumen endobronchial tube: 65% of total cases (13 Case of 20 Case) were displaced by turning of the patient from supine to the lateral decubitus position. |
