This study assessed two disposable devices, the LMA Fastrach™ and the newly developed supraglottic airway device, the Air-Q™, as a conduit for tracheal intubation in 154 healthy adults undergoing elective surgery. Using a non-inferiority approach, the primary outcome measure was successful tracheal intubation within two blind insertion attempts. Successful blind intubation after two attempts was achieved in 75/76 (99%) of the patients in the LMA Fastrach group vs 60/78 (77%) in the Air-Q group (95% CI for the difference 12-32%, p<0.0001). Fibreoptic intubation was used to assist the third attempt. The rate of successful intubation after three attempts was 100% in the LMA Fastrach group and 95% in Air-Q group. The single-use LMA Fastrach appears superior compared with the Air-Q, as a conduit to facilitate blind tracheal intubation.
本研究评估了两种一次性设备，即 LMA Fastrach™ 和新开发的声门上气道装置 Air-Q™，作为 154 名接受择期手术的健康成年人进行气管插管的导管。采用非劣效性方法，主要结局指标是两次盲插尝试内成功进行气管插管。在 LMA Fastrach 组中，76 例患者中有 75 例（99%）在两次尝试后成功进行了盲插，而在 Air-Q 组中，78 例患者中有 60 例（77%）（差值 95%CI 为 12-32%，p<0.0001）。使用纤维支气管镜插管辅助第三次尝试。在 LMA Fastrach 组中，三次尝试后的插管成功率为 100%，在 Air-Q 组中为 95%。与 Air-Q 相比，一次性使用的 LMA Fastrach 似乎更优，可作为辅助盲插的导管。
