Supraglottic airway devices are developed with increasing frequency following the overwhelming success of the laryngeal mask airway (LMA). In contrast to the first generation devices such as the 'classic' LMA and the laryngeal tube second generation devices usually offer an oesophageal drainage tube and/or an improved oropharyngeal leak pressure during positive pressure ventilation such as the laryngeal mask ProSeal and the laryngeal tube S. Recently the disposable versions of these supraglottic airway devices and the novel I-Gel mask have gained increasing interest. Both the LMA and the PLMA have been shown to be perfectly suitable for routine anaesthesia and emergency airway management. While the lacking protection against aspiration is still considered a major limitation of the LMA, the value of airway devices with an oesophageal drainage tube in this respect remains untermined at present.
继喉罩气道（LMA）取得巨大成功之后，声门上气道装置的研发频率日益增加。与第一代装置如“经典”LMA和喉管不同，第二代装置通常配备食管引流管和/或在正压通气期间具有改善的口咽漏气压，如喉罩ProSeal和喉管S。最近，这些声门上气道装置的一次性版本以及新型I-Gel面罩越来越受到关注。LMA和PLMA均已被证明非常适合常规麻醉和紧急气道管理。虽然缺乏防止误吸的保护措施仍被认为是LMA的一个主要局限性，但目前带食管引流管的气道装置在这方面的价值仍未明确。
