The i-gel™ (i-gel) and Laryngeal Mask Airway Supreme™ (LMA Supreme) have been safely used in children. We compared the airway performance of the i-gel and LMA Supreme in infants undergoing general anesthesia.
Sixty infants with American Society of Anesthesiologists physical status I or II were randomly assigned to place either the i-gel or the LMA Supreme. The size 1 or 1.5 of each airway was selected by the weight of infants. The primary outcome variable was oropharyngeal leak pressure (OLP). We also assessed insertion success rate, insertion time, fiberoptic view of the larynx, airway quality, airway manipulations, and perioperative complications.
Demographic data did not differ between the two groups. Insertion success rate was similar in both groups. OLP for the i-gel (26.0 ± 3.8 cmHO) was higher than for the LMA Supreme (23.7 ± 3.2 cmHO) (P = 0.016). Insertion time for the i-gel (16.4 ± 2.8 s) was shorter than for the LMA Supreme (18.5 ± 2.7 s) (P = 0.002). There were no differences in fiberoptic view of the larynx, airway quality, airway manipulations, and complications between the two groups.
This study demonstrated that the i-gel and LMA Supreme provided a similar performance of airway in infants. Compared with the LMA Supreme, the i-gel provided shorter insertion time and higher OLP in infants.
i-gel™（i-gel）喉罩和Laryngeal Mask Airway Supreme™（LMA Supreme）喉罩已在儿童中安全使用。我们比较了i-gel喉罩和LMA Supreme喉罩在接受全身麻醉的婴儿中的气道性能。
60例美国麻醉医师协会身体状况为I或II级的婴儿被随机分配使用i-gel喉罩或LMA Supreme喉罩。根据婴儿体重选择每种气道的1号或1.5号尺寸。主要观察变量为口咽漏气压（OLP）。我们还评估了插入成功率、插入时间、喉镜光纤视野、气道质量、气道操作和围手术期并发症。
两组的人口统计学数据无差异。两组的插入成功率相似。i-gel喉罩的OLP（26.0±3.8 cmH₂O）高于LMA Supreme喉罩（23.7±3.2 cmH₂O）（P = 0.016）。i-gel喉罩的插入时间（16.4±2.8秒）短于LMA Supreme喉罩（18.5±2.7秒）（P = 0.002）。两组在喉镜光纤视野、气道质量、气道操作和并发症方面无差异。
本研究表明，i-gel喉罩和LMA Supreme喉罩在婴儿气道方面表现相似。与LMA Supreme喉罩相比，i-gel喉罩在婴儿中插入时间更短，OLP更高。
