Effect of Chewing Gum and Mouthwash Before Operation on Sore Throat After General Anesthesia With a Laryngeal Mask

Study Overview
=================
Brief Summary
-----------------
Postoperative sore throat (POST) is an important problem after general anaesthesia. We assessed whether chewing gum preoperatively or mouthwash can reduce the incidence of POST after general anaesthesia administered via a streamlined liner of the pharyngeal airway (SLIPA).
