The laryngeal mask airway (LMA) is a relatively recent development that fills the gap in airway management between endotracheal intubation and the use of a face mask. The device is inserted blindly into the pharynx, forming a low-pressure seal around the laryngeal inlet permitting gentle positive-pressure ventilation. It allows the administration of inhaled anaesthetic agents through a minimally stimulating airway. This factor, combined with its ease of insertion, suggested that the laryngeal mask airway might offer some distinct advantages in otolaryngologic paediatric surgery. Our experience in utilizing the laryngeal mask in tonsillectomy and adenoidectomy, and in myringotomies with insertion of ventilating tubes is described, and its advantages and disadvantages are discussed.
喉罩气道(LMA)是一项相对较新的发明,它填补了气管插管和使用面罩之间气道管理的空白。该装置通过盲插方式置入咽部,在喉入口周围形成低压密封,从而实现轻柔的正压通气。它允许通过刺激性极小的气道给予吸入麻醉剂。这一因素,再加上其易于插入的特点,表明喉罩气道在小儿耳鼻喉科手术中可能具有一些明显的优势。本文描述了我们在扁桃体切除术、腺样体切除术以及鼓膜切开置管术中使用喉罩的经验,并讨论了其优缺点。
