We compared the effectiveness of external manual laryngeal fixation (MLF) for tracheal intubation during chest compression using three laryngoscopes, the Macintosh laryngoscope (McL), McGRATH® MAC (McGRGTH), and Pentax-AWS Airwayscope® (AWS) on an adult manikin.
Sixteen novice doctors and 15 experienced anesthesiologists performed tracheal intubation during chest compression on an adult manikin using the McL, McGRATH, and AWS with or without MLF. Tracheal intubation time and intubation success rate were measured.
In the AWS trial, all novice and experienced doctors successfully secured the airway with or without MLF during chest compression. In McL and McGRATH trials, MLF significantly improved the rate of successful intubation during chest compression compared to without MLF for novice doctors. While intubation time did not significantly differ with or without MLF in the AWS trial, MLF significantly shortened intubation time in McL and McGRATH trials for both novice and experienced doctors.
These findings suggest that MLF facilitates tracheal intubation with the McL and McGRATH during chest compression.
我们在成人人体模型上，比较了使用三种喉镜（麦金托什喉镜（McL）、麦格拉思®MAC喉镜（McGRGTH）和宾得-AWS气道镜®（AWS））进行胸外按压时，外部手动喉固定（MLF）对气管插管的有效性。
16名新手医生和15名经验丰富的麻醉医生在成人人体模型上使用McL、McGRATH和AWS进行胸外按压时，在有或没有MLF的情况下进行气管插管。测量气管插管时间和插管成功率。
在AWS试验中，所有新手和经验丰富的医生在胸外按压时有或没有MLF的情况下都成功建立了气道。在McL和McGRATH试验中，与没有MLF相比，MLF显著提高了新手医生在胸外按压时的插管成功率。虽然在AWS试验中，有或没有MLF时插管时间没有显著差异，但在McL和McGRATH试验中，MLF显著缩短了新手和经验丰富医生的插管时间。
这些发现表明，MLF有助于在胸外按压时使用McL和McGRATH进行气管插管。
