Supraglottic airway (SGA) devices are good alternatives for failed intubations or difficult airways. The aim of our study was to compare the success of intubation with SGA devices such as LMA Fastrach (LMA Fastrach), Ambu Aura-i (Aura-i), and Cookgas Air-Q (Air-Q) in an airway manikin by novice practitioners.
This study was conducted in a randomized crossover design using a manikin model. Following training on the equipment used, 36 6-year medical students were randomized into six groups. Participants performed three stages of intubation as follows: the first stage (1S) as SGA insertion, the second stage (2S) as intubation through the SGA, and the third stage (3S) as the removal of the SGA over the intubation tube. The primary outcomes were intubation success and duration.
The successful intubation rate (Stage 1S + 2S + 3S) was 100% for LMA Fastrach and Air-Q and 83.3% for Aura-i ( = 0.002). The median time to intubation was 54.4 s, 55.8 s, and 58.7 s for LMA Fastrach, Aura-i, and Air-Q, respectively ( = 0.794).
Our study shows that novice practitioners can proficiently utilize LMA Fastrach, Air-Q, and Aura-i as SGAs in airway management. LMA Fastrach and Air-Q are more successful for endotracheal intubation than Aura-i. While the successful intubation time with SGA is similar for all three devices, the successful SGA insertion time is shorter with LMA Fastrach and Aura-i compared to Air-Q. Practitioners preferred LMA Fastrach and Air-Q more than Aura-i.
声门上气道（SGA）装置是插管失败或气道困难时的良好替代方案。我们研究的目的是比较新手从业者使用诸如LMA Fastrach（喉罩快插型）、Ambu Aura-i（Aura-i）和Cookgas Air-Q（Air-Q）等SGA装置在气道模型上进行插管的成功率。
本研究采用气道模型进行随机交叉设计。在对所用设备进行培训后，36名6年制医学生被随机分为6组。参与者进行三个阶段的插管操作如下：第一阶段（1S）为插入SGA，第二阶段（2S）为通过SGA进行插管，第三阶段（3S）为在插管导管上移除SGA。主要结局指标为插管成功率和持续时间。
LMA Fastrach和Air-Q的插管成功率（第1S + 2S + 3S阶段）为100%，Aura-i为83.3%（P = 0.002）。LMA Fastrach、Aura-i和Air-Q的插管中位时间分别为54.4秒、55.8秒和58.7秒（P = 0.794）。
我们的研究表明，新手从业者在气道管理中能够熟练地将LMA Fastrach, Air-Q和Aura-i用作SGA。LMA Fastrach和Air-Q在气管插管方面比Aura-i更成功。虽然三种装置使用SGA的成功插管时间相似，但与Air-Q相比，LMA Fastrach和Aura-i的SGA成功插入时间更短。从业者对LMA Fastrach和Air-Q的偏好超过Aura-i。
