This study is designed to compare the effects of alkalinized lidocaine in the endotracheal
tube cuff to a bolus dose of remifentanil given prior to the emergence of anesthesia:
- on the incidence of perioperative coughing
- on the time needed for the emergence of a desflurane-based anesthesia
- on the incidence of sore throat after extubation.
The investigators hypothesis is that the use of alkalinized lidocaine in the endotracheal
tube cuff will reduce the incidence of perioperative coughing after a desflurane-based
