The aim of the present study was to compare two supraglottic airway (SGA) devices (i.e., the i-gel® © Intersurgical Ltd and air-Q® (Reusable) Cookgas company) in terms of the insertion time, amount of leak during ventilation with maximum positive pressure, and postoperative complications in patients referring to Modarres Hospital in Tehran.
The present double-blind clinical trial was performed on 60 patients undergoing elective surgeries that required general anesthesia with muscle relaxation. Patients were randomly assigned to either i-gel® ( = 30) or Air-Q® ( = 30) groups.
The mean age, body mass index, duration of surgery, duration of anesthesia, and gender ratio were not significantly different between the two groups. Mean ± SD values of the SGA devices' insertion time (in seconds) in the air-Q® and i-gel® groups were 4.87 ± 1.6 and 6.80 ± 1.2, respectively (P < 0.001). The mean OLP in the Air-Q® group was significantly higher than that of the i-gel® group (35.9 ± 9.6 versus 24.8 ± 3.7, p < 0.001). The frequency of complications occurred after the supraglottic airway insertion was higher in the i-gel® group. However, only in terms of sore throat, the difference between the two groups was statistically significant: 6 (20%) had sore throat (P = 0.024) in the i-gel groups, but in in the Air-Q® groups no one had this side effect after surgery.
It was concluded that the Air-Q® supraglottic airway was placed faster and easier with fewer complications than the i-gel in general anesthesia with muscle relaxation. The frequency of the occurrence of all three complications, cough, sore throat, and blood, on the cuff (6 (20%) was higher in the i-gel group than that in the air-Q® group (cough3 (10%), sore throat 0 (0%), and blood on the cuff 3 (10%) (P < 0.05).
本研究旨在比较两种声门上气道（SGA）设备（即 i-gel ® ® （Intersurgical Ltd 公司）和 air-Q ® （可重复使用）（Cookgas 公司））在插入时间、通气时最大正压漏气量以及德黑兰 Modarres 医院就诊患者的术后并发症方面的差异。
本双盲临床试验纳入了 60 例需全身麻醉并肌松的择期手术患者。患者随机分为 i-gel ® 组（n=30）或 air-Q ® 组（n=30）。
两组患者的年龄、体重指数、手术时间、麻醉时间和性别比例无显著差异。air-Q ® 组和 i-gel ® 组 SGA 装置插入时间（秒）的均值±标准差分别为 4.87±1.6 和 6.80±1.2（P<0.001）。Air-Q ® 组的平均 OLP 明显高于 i-gel ® 组（35.9±9.6 与 24.8±3.7，P<0.001）。i-gel ® 组 SGA 插入后并发症的发生率更高，但仅在咽痛方面，两组间差异具有统计学意义：i-gel ® 组 6 例（20%）发生咽痛（P=0.024），而 air-Q ® 组术后无人发生此副作用。
在全身麻醉并肌松的情况下，与 i-gel ® 相比，Air-Q ® 声门上气道插入更快、更简单，且并发症更少。i-gel ® 组三种并发症（咳嗽、咽痛、气切套囊上出血）的总发生率（6 例（20%））高于 air-Q ® 组（咳嗽 3 例（10%），咽痛 0 例（0%），气切套囊上出血 3 例（10%））（P<0.05）。
