Air-Q™ intubating laryngeal airway (ILA) has been used successfully as a conduit for tracheal intubation in pediatric difficult airway. However, its use as an airway device and conduit for intubation in infants is not yet evaluated.
The primary objective was to evaluate ILA as a conduit for tracheal intubation in infants, and secondary objectives were to evaluate ILA in terms of ease of insertion and ventilation, oropharyngeal leak pressure (OLP), glottic view, and complications.
Twenty infants with normal airway were included. After induction of general anesthesia and neuromuscular blockade, ILA (size 1.0/1.5) was inserted. Fiberoptic bronchoscope (FOB)-guided intubation and removal of ILA with the stabilizing stylet was attempted.
The mean age and weight of the infants were 7.5 ± 2.3 months and 7.3 ± 1.8 kg. The ILA sizes 1.0 and 1.5 were inserted in 10 infants each according to the weight of the infants. The mean OLP was 18.5 ± 1.8 cm H₂O, and mean time for insertion of ILA was 13.3 ± 3.9 s. Glottic view was grade I in 6, grade II in 1, grade III in 4, and grade IV in nine infants. Tracheal intubation was successful in 19/20 infants. The mean endotracheal tube (ETT) insertion time and mean total time (ILA insertion to the confirmation of ETT placement) were 95.6 ± 32.3 s and 306.42 ± 120.2 s respectively.
The ILA is a safe and easy-to-use supraglottic airway device for intubation with FOB in infants with normal airway. Insertion and removal of ILA are easy with satisfactory oropharyngeal seal and ventilation.
Air-Q™ 插管喉罩气道（ILA）已成功用作小儿困难气道气管插管的通道。然而，其作为婴儿气道装置和插管通道的应用尚未得到评估。
主要目的是评估 ILA 作为婴儿气管插管通道的效果，次要目的是评估 ILA 在插入和通气的难易程度、口咽漏气压（OLP）、声门视野及并发症方面的情况。
纳入 20 例气道正常的婴儿。在全身麻醉和神经肌肉阻滞诱导后，插入 ILA（1.0/1.5 型号）。尝试在纤维支气管镜（FOB）引导下插管并使用稳定管芯取出 ILA。
婴儿的平均年龄和体重分别为 7.5±2.3 个月和 7.3±1.8 千克。根据婴儿体重，1.0 型号和 1.5 型号的 ILA 各插入 10 例婴儿。平均 OLP 为 18.5±1.8 cmH₂O，ILA 的平均插入时间为 13.3±3.9 秒。6 例婴儿声门视野为 I 级，1 例为 II 级，4 例为 III 级，9 例为 IV 级。20 例婴儿中有 19 例气管插管成功。气管内导管（ETT）的平均插入时间和平均总时间（从插入 ILA 到确认 ETT 位置）分别为 95.6±32.3 秒和 306.42±120.2 秒。
ILA 是一种安全且易于使用的声门上气道装置，适用于气道正常的婴儿在 FOB 引导下插管。ILA 的插入和取出操作简便，口咽密封和通气效果良好。
