• Status: Completed
• Trial end date: 2009-02-01
• Target enrollment: 0
• Participant gender: Female

Summary

It has been proven that tracheal tube inflated with lidocaine could decrease the post-intubation sore throat in nitrous oxide anesthesia. In the study, the investigators would like to evaluate the effect of lidocaine inflation in non-nitrous oxide anesthesia and compare the effect of tetracaine, the best mucosal local anesthetics with lidocaine.
