Brief summary
The purpose of this study is to determine if chewing gum immediately prior to transport to the operating room reduces the severity of post-operative sore throat in patients who have an LMA (laryngeal mask airway) placed for procedures with duration greater than 1 hour.
Detailed description
Patients will be randomized into two groups. Group 1 will receive a piece of gum immediately prior to transport to the operating room. They will be asked to chew the gum for 2 minutes and then spit the gum in the garbage. Group 2 will not receive any gum. They will be asked to swallow twice and have no other intervention.
