John Russell 17th May 2000 The blind guided technique for insertion of double lumen (tracheobronchial) tubes was described in 1992 (Anaesthesia & Int. Care 20,71-74). Since then this technique has been taught widely. There are several important steps in the effective use of this technique. These are:- a) Recognition that the diameter of the bronchus (usually the left) is a crucial determinant of success. This size can be found from the standard P-A chest X-ray, which magnifies the air bronchogram by about 10% as the bronchi are about 15 cm from the plate. Once this is known, the correct size double lumen tube can be selected. Unfortunately, the diameter of the bronchial tube for any nominal size varies with the manufacturer. A table is given to guide the correct size.Manufacturer

This should leave the tube about 6 cm above its final position. At this point, the bronchial cuff is inflated in the trachea until the leak on inflation stops. Now the bronchial arm is connected directly to the circuit and both lungs of the patient ventilated through the bronchial tube (Fig 1).

Both lungs ventilated. c) With each breath, the tube is advanced into the trachea until the bronchial segment plugs the bronchus (Fig 2). The endpoint signs are:
[*]Resistance to advancement. (Good even with low compliance lungs).[*]Unilateral ventilation by observation and by auscultation.[*]Reduction in compliance (Often best seen with IPPV with a ventilator).At this point, the tube is about 2.5 to 3 cm (bronchial cuff length plus 1 cm) from its final position.

DL tube with over-inflated bronchial cuff plugging left main bronchus. d) Once the bronchial plugging point has been identified, the cuff is deflated and the tube inserted an additional length (bronchial cuff length + 1 cm). The final bronchial cuff inflation to seal is then usually about 1-2 ml. The patient connection is now changed to the tracheal connection and the tracheal cuff inflated until a seal is made in the trachea (Fig 3).

In a difficult case, the estimated length from plugging can be used for final insertion even if the bronchial cuff has to be deflated to get the tube positioned into the left main bronchus. If a tube goes right, turning the head 90? so that the chin is on the right shoulder and rotating the tube on its axis to restore the bronchial tube to point laterally, can usually achieve insertion into the left main bronchus. The distance inserted is then that previously determined from the right bronchial plugging. 精品资源，谢谢分享！
请教祥子，患者额头上贴的白色的是什么东东？ 我冒昧的回答一下楼上的，那可能是BIS的电极片。 请教一下，你们是过声门就拔管芯还是送到支气管再拔呢，我们两种都有，有统一的吗 楼主可以翻译成中文吗？谢谢！ 回复 6# 289684097
这就是英语很重要的，自己好好看看才能学到知识的~！~ 图片看不到，是我电脑的原因吧
