Background The aim of the study was to evaluate the risk for postoperative sore throat (POST) using the self-pressurizing Air Q compared with that using classic laryngeal mask airway (LMA). Patients and methods A total of 150 patients were included in this double-blind prospective study. After induction of general anesthesia, the airway was maintained with an Air Q device (in group Q, 75 patients) and with a classic LMA (in group C, 75 patients). The POST was evaluated and graded (on the basis of its severity) within 20 min in the recovery room and 24 h after surgery. Results The incidence of POST and its severity were comparable in both groups. Conclusion Despite the self-pressurizing cuff of Air Q, there was no reduction in the POST incidence or severity compared with that using classic LMA.
