可弯曲喉罩的临床应用进展

背景 可弯曲喉罩(flexible laryngeal mask airway,FLMA)是专为头颈、上躯干手术设计的一种声门上人工气道装置,由与经典喉罩(classic laryngeal mask airway,CLMA)相同的通气罩及充气阀和带螺旋形钢丝的通气管组成,兼具普通喉罩操作简便、呼吸道刺激小、血流动力学稳定、术后并发症少等优点,及加强型气管导管的可弯曲性、抗折抗扭曲性、不干扰术野等优点,在临床中被逐渐推广. 目的 了解FLMA的分类,掌握FLMA使用方法及适用范围. 内容 对FLMA的发展历史及特点、应用前选择及检查、置入及拔除操作、术中管理及应用现状进行总结. 趋向 对FLMA目前存在的问题及改良方向进行探讨.

Clinical application advance in flexible laryngeal mask airway

Background The flexible laryngeal mask airway (FLMA) is an artificial superglottic device used in surgery to the head,neck and upper torso.It is identical to the classic laryngeal mask airway (CLMA) expect that the airway tube is supported by a continuous coil of wire.It is convenience mild damage,circulatory stabilization,less complication and more flexibility,resistance to compression,combining the advantages of the standard device and the reinforced endotracheal tube these features make it clinically useful.Objective It is needed to learn the classification,method and application of FLMA.Content This review summarize the development,feature,selection,examination,insertion,administration,extraction and application of FLMA.Trend The review proposes some improvements to solve the problems encountered in clinical using.
