Laryngeal obstruction is a challenging complication during anaesthesia with a face mask or laryngeal mask and is due to insufficient analgesia in most cases. However, with a laryngeal mask in place it must be differentiated whether the airway obstruction is caused by the laryngeal mask itself or by other factors. Knowledge of the pathophysiology of the laryngeal closure and experience with the use of the laryngeal mask are essential for adequate treatment. Not the removal of a correctly inserted laryngeal mask which initially provided a satisfying airway, but the relaxation of laryngeal muscle activity by adequate anaesthesia is the first mandatory treatment if intraoperative airway obstruction occurs.
喉梗阻是面罩或喉罩麻醉期间具有挑战性的并发症，在大多数情况下是由于镇痛不足所致。然而，在喉罩就位时，必须区分气道梗阻是由喉罩本身还是其他因素引起的。了解喉关闭的病理生理学以及使用喉罩的经验对于充分治疗至关重要。如果术中发生气道梗阻，首先必须采取的治疗措施不是移除最初能提供满意气道的正确插入的喉罩，而是通过充分麻醉来松弛喉肌活动。
