The laryngeal mask airway, the LMA® Gastro™ (Teleflex Medical, Athlone, Ireland), is a novel airway device which permits upper gastrointestinal (GI) endoscopy to be performed via a dedicated large calibre oesophageal lumen. It has been validated in adult studies, but to our knowledge, there have been no data published regarding its use in a paediatric population. Following a brief education programme, the LMA Gastro was introduced on a trial basis at our institution and made freely available. Over a four-month period, our pre-existing endoscopy audit framework captured data on a total of 55 patients who had the LMA Gastro device chosen as the primary airway for elective upper GI endoscopy. These data were collected prospectively by the treating anaesthetist and included a range of airway and endoscopy outcomes. Of the 55 patients, the LMA Gastro provided an adequate airway in 52 (94.5%). Forty-six (88.5%) were sited on first attempt, and 50 (96.2%) insertions were rated 'easy' by the anaesthetist. Aside from three insertion failures, there were no airway events. The endoscopy success rate was 100% in the 52 patients who had an LMA Gastro airway successfully inserted. First-pass oesophageal access was achieved in 51 (98%) cases, and 100% of insertions were rated 'easy' by the gastroenterologist. Despite our relative inexperience with it, the device had a high success rate for airway maintenance and oesophageal access in our paediatric patient population. In our institution, the LMA Gastro provided a useful airway option in older children undergoing elective upper GI endoscopy.
喉罩气道，即 LMA® Gastro™（Teleflex Medical，爱尔兰奥唐奈），是一种新型气道装置，可通过专用大口径食管腔进行上消化道（GI）内镜检查。它已在成人研究中得到验证，但据我们所知，尚未有关于其在儿科人群中应用的数据发表。在进行简短的教育计划后，我们的机构开始试用 LMA Gastro，并将其免费提供。在四个月的时间里，我们现有的内镜检查审核框架收集了总共 55 名患者的数据，这些患者选择 LMA Gastro 设备作为择期上 GI 内镜检查的主要气道。这些数据由主治麻醉师前瞻性收集，包括一系列气道和内镜检查结果。在 55 名患者中，52 名（94.5%）的 LMA Gastro 提供了足够的气道。46 名（88.5%）患者在首次尝试时定位成功，50 名（96.2%）插入操作被麻醉师评为“容易”。除了 3 次插入失败外，没有发生气道事件。在 52 名成功插入 LMA Gastro 气道的患者中，内镜成功率为 100%。51 例（98%）患者首次通过食管进入，100%的插入操作被胃肠病学家评为“容易”。尽管我们经验相对不足，但该设备在我们的儿科患者群体中维持气道和食管进入方面具有很高的成功率。在我们的机构中，LMA Gastro 为接受择期上 GI 内镜检查的大龄儿童提供了一种有用的气道选择。
