The LMA has been commercially available since 1988, and in the United States since 1992. The device combines several advantages of endotracheal tubes and face masks and may be used in many situations where either device was previously used routinely. Its principal advantage is a clearer airway, without the morbidity associated with endotracheal intubation. Although not suitable for all patients and procedures, the LMA has become widely used in all other countries where it is available. Many of the surgical procedures for which the LMA is most suited are performed in outpatients, and we expect this device will soon become popular in carefully selected cases in this country.
喉罩自1988年开始商业化销售，1992年进入美国市场。该装置兼具气管内导管和面罩的多种优点，可用于许多以前常规使用这两种装置之一的情况。其主要优点是气道更通畅，且无气管插管相关的发病率。尽管喉罩并不适用于所有患者和操作，但在其他有该产品的国家已得到广泛应用。喉罩最适用的许多外科手术都是在门诊进行的，我们预计该装置很快会在我国精心挑选的病例中流行起来。
