Supraglottic airway device is presently the most common modality of airway management in children for short surgical procedures. The i-gel is one such novel supraglottic airway device with a non-inflatable cuff. The objective of the present study was to evaluate the efficiency of i-gel compared to LMA Proseal regarding oropharyngeal leak pressure, insertion time, ease of insertion, and fibreoptic view of larynx.
After obtaining ethical clearance and parental consent, 70 children aged 2-10 years, weighing 10-30 kg were randomised to receive LMA Proseal or i-gel for airway management. Data with respect to oropharyngeal leak pressure, insertion time, ease of insertion, number of attempts, and fibreoptic score were collected. The primary outcome was the oropharyngeal leak pressure with the two supraglottic airway devices measured by manometric stability.
Demographic data were comparable between the two groups. The oropharyngeal leak pressure (LMA Proseal vs. i-gel, 20.51 ± 4.71 cmHO vs. 19.57 ± 5.71 cmHO), ease of insertion, number of attempts, and fibreoptic view score was similar between the two groups. The insertion time was faster with i-gel (22.63 ± 5.79 s) compared to LMA Proseal (43.26 ± 7.85 s).
I-gel was similar to LMA Proseal with respect to oropharyngeal leak pressure in children under controlled ventilation.
在儿童进行短期手术时，目前最常用的气道管理方法是使用声门上气道装置。i-gel 是一种新型的非充气式声门上气道装置。本研究旨在评估 i-gel 与 LMA Proseal 在气道管理方面的有效性，比较两者的经口咽漏气压、插入时间、插入难易程度和纤维喉镜下的喉部显露效果。
本研究获得伦理委员会批准并征得家长同意后，将 70 名年龄在 2-10 岁、体重在 10-30kg 的儿童随机分为 LMA Proseal 组和 i-gel 组，分别使用这两种声门上气道装置进行气道管理。收集两组的经口咽漏气压、插入时间、插入难易程度、尝试次数和纤维喉镜评分等数据。主要观察指标为两种声门上气道装置的经口咽漏气压，通过压力计测量管腔稳定性来评估。
两组儿童的一般资料无统计学差异。LMA Proseal 组和 i-gel 组的经口咽漏气压（20.51±4.71cmH2O vs. 19.57±5.71cmH2O）、插入难易程度、尝试次数和纤维喉镜评分相似。i-gel 组的插入时间（22.63±5.79s）快于 LMA Proseal 组（43.26±7.85s）。
在儿童控制通气下，i-gel 与 LMA Proseal 相比，经口咽漏气压无显著差异。
