PURPOSE
To assess epiglottic position after laryngeal mask airway (LMA) insertion with or without the use of a laryngoscope.
METHODS
A double-blind randomized study. In 48 children an LMA (#2 for 6-20 kg, #2.5 for 20-30 kg) was inserted either blindly or with the help of a laryngoscope and its position assessed using fibreoptic endoscopy.
RESULTS
An unobstructed view of the glottis, as assessed by fibrescope, was observed in 10 of 25 patients in the laryngoscope group, but only in 1 of 22 patients in the blind insertion group (P = 0.005).
CONCLUSION
This technique offers an alternative when the standard technique has failed, or when LMA insertion precedes bronchoscopy or intubation via the laryngeal mask.
目的
评估在使用或不使用喉镜的情况下插入喉罩气道（LMA）后会厌的位置。
方法
一项双盲随机研究。在48名儿童中，将一个LMA（6 - 20千克用2号，20 - 30千克用2.5号）通过盲插或在喉镜辅助下插入，并使用纤维内镜评估其位置。
结果
在喉镜组的25名患者中，有10名通过纤维镜观察到声门视野通畅，但在盲插组的22名患者中只有1名（P = 0.005）。
结论
当标准技术失败时，或者在通过喉罩进行支气管镜检查或插管之前插入LMA时，这项技术提供了一种替代方法。
