Supraglottic Mask Airways such as the LMA have been in the U.S. market since the early 1990"s.They are used as an alternative to the combination of face masksand other airway devices.

气道通气罩作为喉罩早已在1990年的美国市场盛行,他们用作于能代替气道装置和面罩相结合的产品


Incubating Laryngeal Airways are inserted into the pharynx and create a low pressure sealaround the laryngeal inlet in the pharynx.

喉罩被插入咽喉部,同时在咽喉部创建了一个低压且密闭的空间围绕在咽喉。


All alternative airways share the same basic principle -- a tube delivers oxygen and or gaswithout penetrating the vocal cords(glottis) - hence the generic name of supraglottic airways.

These airways genera\ have one or two cuffs that inflate in the lower pharynx to createa seal enabling oxygen (gas) delivery. These devices are alternatives to ET tubes thatpenetrate the glottis and to mask ventilation.

可选的气道通气设备都有同一个原则——通过管路输送氧和气,但对声门无影响。因此,他们有着通用的名称"喉罩"。这些装置都有1个或2个面罩,在会厌部与喉腔形成一个密闭的、只供气体通过的空间。这些设备代替ET管穿透声门产生通气。


Supraglottic Airways provide an effective method of forming an airway during anesthesiain patients. The airways are more secure than a face mask while less invasive than intubationwith an ET tube. They are used when tracheal intubation is not necessary or during anunexpected difficult airway situation. Patients requiring controlled orassisted-ventilation receive fresh gas through the airway connector.

喉罩通过一个有效的方法,给麻醉后的病人进行人工通气,且比面罩直接插管更安全,伤害更小。

在气管插管时使用喉罩,就不必在困难的咽喉条件下进行插管。病人需要通过喉罩中通管进行控制或辅助通气。


The growing popularity of these devices stem from their ease-of-use, their role in the difficultairway and the advantages it offers over the face mask and more invasive tracheal intubation.

随着医疗设备的日益普及,气道通气从困难至发展提高,它提供了超出于面罩和有创气管插管的优势。


General Advantages of supraglottic airways over tracheal intubation with an E.T tube are:

与普通气管插管与有创气管插管相比较:


Clinicians find they are quicker and easier to insert.

医生们发现 喉罩更方便、更容易插入。


Less resistance to breathing.

减轻了呼吸产生的阻力


Less incidence of sore throat.

减少咽喉部的术后并发症


Smaller hemodynamic and respiratory response to insertion, maintenance and removal. This allows use of lighter levels of anesthesia agents than what might otherwise be necessary.

插入与拔出时,呼吸系统及心血管系统的反应较小,可无需使用喉镜及麻醉剂
