During tracheal intubation with the Airtraq laryngoscope (AL), the tracheal tube tip sometimes impinges on the glottis or other laryngeal structures. We tested a hypothesis that Parker flex-tip tube (PT) makes AL assisted tracheal intubation easier and faster than a conventional tube (Mallinckrod Hi-Lo tube : HT).
Study 1. Fifty patients were assigned to group PT (n = 25) or group HT (n = 25). After induction of general anesthesia, intubation was performed with AL. We recorded tube passage time, the number of tube impingements, circulatory changes and incidences of postoperative complications. Study 2. Twenty patients were divided into two groups and intubated either by HT or PT. We assessed the tip direction and contact points of each tube.
Study 1. The use of PT significantly reduced the number of tube impingements compared to HT. Tube passage time in group PT was shorter than that in group HT, but the difference was not statistically significant. Study 2. The tube tip contact with the vocal cords was more frequent with HT.
PT significantly reduced the number of impingements. The shape of tube tip and the smaller angle of PT when fitted in AL contributed to the relative ease of tube passage.
在使用Airtraq喉镜（AL）进行气管插管时，气管导管尖端有时会撞击声门或其他喉部结构。我们检验了一个假设，即派克弯曲尖端导管（PT）使AL辅助气管插管比传统导管（马林克罗德高低位导管：HT）更容易、更快。
研究1。50例患者被分为PT组（n = 25）或HT组（n = 25）。全身麻醉诱导后，使用AL进行插管。我们记录了导管通过时间、导管撞击次数、循环变化和术后并发症的发生率。研究2。20例患者分为两组，分别使用HT或PT进行插管。我们评估了每根导管的尖端方向和接触点。
研究1。与HT相比，使用PT显著减少了导管撞击次数。PT组的导管通过时间短于HT组，但差异无统计学意义。研究2。HT与声带的导管尖端接触更频繁。
PT显著减少了撞击次数。导管尖端的形状以及PT安装在AL中时较小的角度有助于导管相对容易通过。
