Background And ObjectiveSore 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.MethodSeventy 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.ResultsOn 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 24hours, 2.9% (n=1) of the kids in Ambu Group 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 (p=0.28); after 1 hour (p=0.28); after 6 hours (p=0.30); and after 24 hours (p=0.31). The duration of the insertion was shorter in Ambu Group and it was easier to insert the I-gel® (p=0.029). Oropharyngeal seal pressure of I-gel® was higher than that of Ambu laryngeal mask (p=0.001).ConclusionThe severity and frequency of postoperative sore throat in children is not statistically significant in the I-gel Group compared to Ambu Group.Copyright © 2020 Sociedade Brasileira de Anestesiologia.
