Efficacy of Alkalinized Lidocaine in the Endotracheal Tube Cuff on the Incidence of Coughing During Emergence

This study is designed to compare the efficacy of endotracheal tube cuffs pre-filled with alkalinized lidocaine on the: * incidence of coughing during emergence of general anesthesia * time needed for emergence following a desflurane-based anesthesia * incidence of sore throat after extubation. The investigator\'s hypothesis is that the use of endotracheal tube cuffs pre-filled with alkalinized lidocaine will reduce the incidence of coughing by 50% relative to a control group following a desflurane-based anesthesia.
