Air Q和插管型喉罩作为模拟颈椎固定患者插管通道的比较：

一项前瞻性观察研究

插管型喉罩（ILMA）可用于插管尝试期间的通气和氧合，但成功率在33%至96%之间。

Air Q是一个相对较新的器械。

帕克软管有助于无创伤性插管。

本研究的主要目的是比较在模拟颈椎固定的患者中使用Air Q和ILMA作为parker软管的插管通道的效果。

这是一项单盲、随机、前瞻性和对比研究，在91名年龄在18岁至60岁之间的男女患者中进行，这些患者计划在全身麻醉下进行择期手术，美国麻醉师学会身体状况（ASA）I和II级。

研究流程如下图

两组患者的一般情况如下

每组45名患者中，43名患者成功放置Air Q，44名患者成功放置ILMA。

35.56%的患者放置Air Q时需要调整，而对于放置ILMA，只有15.56%患者需要调整。 39例患者通过AIR Q插管成功，44例患者通过ILMA插管成功，但两组之间无显著差异。 尝试次数和导管插入时间具有可比性。 进行气管插管的尝试次数、所需操作次数和时间相似。

两组的咳嗽和喉咙痛发生率具有可比性。 我们得出结论，在模拟颈椎固定的患者中，使用Parker软管进行气管插管时，ILMA的成功率高于Air Q。需要更优化的操作技巧来放置Air Q。 关键词： Air Q；帕克软管；颈托；困难气道；气管导管；插管型喉罩；插管；插管通道；手动线性稳定；模拟颈椎固定；声门上装置。 

原文摘要 Comparison between Air Q and intubating laryngeal mask airway as intubation   in patients with simulated fixed cervical spine: a prospective observational study The intubating laryngeal mask airway (ILMA) can be used for ventilation and oxygenation between intubation attempts, but there is a varied success rate ranging from 33% to 96%. Air Q is a relatively new entrant. Parker flex tube aids in atraumatic intubation. The primary aim of this study was to compare Air Q intubating laryngeal airway with ILMA as intubation conduits in patients with simulated fixed cervical spine using a Parker flex tube. It was a single-blinded, randomized, prospective, and comparative study conducted on 91 patients aged between 18 to 60 years of either sex, scheduled to undergo elective surgery under general anesthesia belonging to the American Society of Anesthesiologists physical status I and II. Out of 45 patients in each group, Air Q was successfully placed in 43 patients and ILMA was successfully placed in 44 patients. 35.56% of the patients required maneuvers for placing the Air Q, whereas, for placing the ILMA, only 15.56% of the patients required maneuvers. Intubation through the AIR Q was successful in 39 patients and through the ILMA in 44 patients, but there was no significant difference between the two groups. The number of attempts and the time of device insertion were comparable. There were a similar number of attempts, maneuvers required, and time is taken for endotracheal intubation. The incidence of cough and sore throat was comparable in both groups. We conclude that ILMA has a higher success rate than Air Q for tracheal intubation with Parker Flex tube in patients with simulated fixed cervical spine. More optimized maneuvers were required for the placement of Air Q.
