The laryngeal adductor reflex (LAR) is a brainstem reflex that closes the vocal fold and constitutes a new method for continuously monitoring the vagus and laryngeal nerves during different surgeries. Previous reports concluded that topical lidocaine in spray inhibited LAR responses. However, topical anesthesia in the upper airway may be necessary in awake intubation. We present six patients who underwent neck endocrine surgery due to an intrathoracic goiter that compromised the airway. Before awake intubation, a nebulization of lidocaine 5% was applied for at least 10 min. The intubation procedure was well tolerated, and bilateral LAR with suitable amplitudes for monitoring was obtained in all cases. In our series, the nebulization of lidocaine 5% did not affect the laryngeal adductor reflex. Laryngoscope, 134:4161-4164, 2024.
喉内收反射（LAR）是一种脑干反射，可使声带闭合，为在不同手术期间持续监测迷走神经和喉返神经提供了一种新方法。先前的报告得出结论，喷雾利多卡因可抑制 LAR 反应。然而，在上呼吸道进行局部麻醉可能在清醒插管时是必要的。我们介绍了 6 例因胸腔内甲状腺肿导致气道受损而接受颈部内分泌手术的患者。在清醒插管前，应用 5%利多卡因雾化至少 10 分钟。所有患者均能很好地耐受插管过程，并获得双侧具有适当监测幅度的 LAR。在我们的系列研究中，5%利多卡因的雾化并未影响喉内收反射。《喉镜》，134：4161-4164，2024。
