Sore throat is well recognized complaint after receiving general anesthesia. This study is conducted to compare the severity and frequency of postoperative sore throat in children undergoing elective surgery, following the use of Ambu laryngeal mask airway or I-gel®, who are able to self-report postoperative sore throat.
Seventy children, 6 to 16 years-old, undergoing elective surgery randomly allocated to either Ambu laryngeal mask (Ambu Group) or I-gel® (I-gel Group). After the procedure, patients were interviewed in the recovery room immediately, after one hour, 6 and 24 hours postoperatively by an independent observer blinded to the device used intra-operatively.
On arrival in the recovery room 17.1% (n = 6) of children of the Ambu Group complained of postoperative sore throat, against 5.7% in I-gel Group (n = 2). After one hour, the results were similar. After 6 hours, postoperative sore throat was found in 8.6% (n = 3) of the children in Ambu group vs. 2.9% (n = 1) in I-gel Group. After 24 hours, 2.9% (n = 1) of the children in Ambu Group complained of postoperative sore throat compared to none in I-gel Group. There was no significant difference found in the incidence of postoperative sore throat in both devices on arrival ( = 0.28); after 1 hour ( = 0.28); after 6 hours ( = 0.30); and after 24 hours ( = 0.31). The duration of the insertion of Ambu laryngeal mask was shorter and it was easier to insert than I-gel® ( = 0.029). Oropharyngeal seal pressure of I-gel® was higher than that of Ambu laryngeal mask ( = 0.001).
The severity and frequency of postoperative sore throat in children is not statistically significant in the I-gel Group compared to Ambu Group.
咽痛是全身麻醉后常见的主诉。本研究旨在比较择期手术患儿使用喉罩或I-gel®后，术后咽痛的严重程度和发生率，这些患儿能够自行报告术后咽痛情况。
70名6至16岁行择期手术的患儿被随机分为喉罩组（喉罩组）或I-gel®组（I-gel组）。手术结束后，由一名对术中使用的器械不知情的独立观察者在恢复室立即、术后1小时、6小时和24小时对患者进行访谈。
到达恢复室时，喉罩组17.1%（n = 6）的患儿主诉术后咽痛，而I-gel组为5.7%（n = 2）。1小时后，结果相似。6小时后，喉罩组8.6%（n = 3）的患儿出现术后咽痛，而I-gel组为2.9%（n = 1）。24小时后，喉罩组2.9%（n = 1）的患儿主诉术后咽痛，而I-gel组无患儿出现。两种器械在到达时（P = 0.28）、1小时后（P = 0.28）、6小时后（P = 0.30）和24小时后（P = 0.31）术后咽痛的发生率均无显著差异。喉罩的插入时间较短，且比I-gel®更容易插入（P = 0.029）。I-gel®的口咽密封压力高于喉罩（P = 0.00）。
与喉罩组相比，I-gel组患儿术后咽痛的严重程度和发生率无统计学差异。
