Abstract and Introduction
Abstract
Background: We studied whether laryngoscopy and tracheal intubation were easier when using the Pentax-AWS (Tokyo, Japan), a new videolaryngoscope, than when applying the Macintosh laryngoscope, during manual in-line neck stabilization.
Methods: In 203 anaesthetized patients with manual in-line neck stabilization, we inserted the Pentax-AWS and a Macintosh laryngoscope, in turn, and recorded the view of the glottis and time taken to laryngoscopy. The success rate of tracheal intubation (within 120 s) and time to intubation were also recorded.
Results: The view of the glottis was significantly better with the Pentax-AWS than with the Macintosh laryngoscope (P<0.001). For the Macintosh laryngoscope, the view was obscured in 22 of 203 patients (11%) (Grade 3 in 21 patients and Grade 4 in one patient), whereas for the Pentax-AWS, the glottis was always clearly seen (Grade 1). Time taken to see the glottis with the Pentax-AWS [mean (SD): 6.0 (3.1) s] was significantly shorter than with the Macintosh laryngoscope [11.0 (5.0) s] (95% CI for difference: 4-6 s). The success rate of tracheal intubation with the Pentax-AWS (all of 99 patients) was significantly higher than with the Macintosh laryngoscope (93 of 104 patients) (P=0.001). Time taken for intubation was similar between the Macintosh laryngoscope [51 (27) s] and the Pentax-AWS [54 (14) s] (95% CI for difference: -9 to 3 s).
Conclusions: In patients with stabilized neck, the Pentax-AWS provided a better view of the glottis and a higher success rate of tracheal intubation, compared with the conventional Macintosh laryngoscope.

好家伙，够先进的哦，变成了可视插管，可能很昂贵吧！

与可视喉镜有什么区别呢？？？除了显像系统以外，前端的镜片还有差别啊？？？

不错这样我们就不用直对着病人的口腔了并且可以预防传染病

看是国人在操作，太酷了！
这么好的东西太诱人了，只有成人用的镜片吗？哪儿有啊、报价多少？

我们医院也有这种可视喉镜用过几次不过对于绝对的困难气道这个东西还是不一定搞得赢哈不要被表面现象所迷惑比如说下颌骨骨折的病人不可能用它来插一般都会用纤维支气管镜插起来也很恼火的有的要助手把患者的舌头拉出来才可以顺利插好！

很先进呀，只是不知道能不能推广，感觉还是急诊科用这个合适

够先进的,希望有机会实际操作,体会一下,

好家伙，只是不知道要多少钱一套啊？
