The laryngeal mask airway (LMA) has been used extensively to provide a safe airway in spontaneously breathing patients who are not at risk from aspiration of gastric contents. The role of the LMA in the event of a failed intubation in an obstetrical patient, and its place in a failed intubation drill remains unclear. Two hundred and fifty consultant obstetric anaesthetists in the United Kingdom were asked to complete an anonymous questionnaire regarding their views about using the laryngeal mask airway (LMA) in obstetrical anaesthesia. The LMA was available in 91.4% of obstetric units. Seventy-two per cent of anaesthetists were in favour of using the LMA to maintain oxygenation when tracheal intubation had failed and ventilation using a face mask was inadequate. Twenty-four respondents had had personal experience with the LMA in obstetrical anaesthesia, eight of whom stated that the LMA had proved to be a lifesaver. We believe that the LMA has a role in obstetrical anaesthesia when tracheal intubation has failed and ventilation using a face mask proves to be impossible, and it should be inserted before attempting cricothyroidectomy.
喉罩气道（LMA）已被广泛用于为无胃内容物误吸风险的自主呼吸患者提供安全气道。LMA在产科患者插管失败时的作用及其在插管失败演练中的地位仍不明确。英国250名产科麻醉顾问被要求填写一份关于他们对在产科麻醉中使用喉罩气道（LMA）看法的匿名问卷。91.4%的产科单位备有LMA。72%的麻醉医生赞成在气管插管失败且面罩通气不足时使用LMA维持氧合。24名受访者有在产科麻醉中使用LMA的个人经验，其中8人表示LMA已被证明是救命设备。我们认为，当气管插管失败且面罩通气无法实现时，LMA在产科麻醉中具有作用，并且应在尝试环甲膜切开术之前插入。
