29、 anesthesia.成功要点Tips for Success经鼻气管插管要比经口插管容易Nasal intubation is easier than oral intubation请助手帮忙挡开舌并托起下颌打开气道，同样可用Ovassapian 通气道帮助经口气管插管。Ask assistant to pull our tongue and give chin liftto open up airway.Can also use Ovassapian Airway to aid in oral intubation.纤支镜更容易通过内径较小的气管导管是因为其直径差异更小Easier to

30、 thread smaller endotracheal tube over fiberscope because of the smaller difference in diameter如果气管内导管不能轻易的通过，旋转180度。同样可以使用末端呈锥形的气管导管。If endotracheal tube(ETT)does not pass easily,turn it 180 degrees.Can also use tapered end ETT.气道阻滞不充分可能会导致喉痉挛Inadequate airway block may cause laryngospasm练习，练习，再练习！练习，练习，再练习！PRACTICE,PRACTICE,PRACTICE!Awake FOI videoAristotle,The Nicomachean Ethics“For the things we have to learn before we can do them,we learn by doing them.”“对于很多事情我们需要先学习，才能去做，我们从实践中学习他们。”亚里士多德,Nicomachean 伦理学谢谢聆听
