Summary
A previous study demonstrated topical lidocaine spray on the larynx and the trachea is
effective in reducing hemodynamic response to laryngoscopy and endotracheal intubation. In
clinical practice, blind oropharyngeal application of lidocaine without aiding direct
laryngoscopy can not assured that sprayed lidocaine effectively reaches the larynx and
trachea. Therefore, direct laryngoscopy should be necessary to reach topical lidocaine to
correct sites. Unfortunately, direct laryngoscopy itself can affect hemodynamics during
spraying lidocaine. In this study, we will investigate an effect of lidocaine sprayed on
direct laryngoscopy and the tracheal mucosa on hemodynamic change throughout intubation.
