Summary
The goal of this clinical trial is to to evaluate the efficacy of lidocaine sprayed at the laryngeal inlet combined with the endotracheal tube cuff compare with intravenous lidocaine on the hemodynamic response to laryngoscopy and intubation in patients undergoing elective neurological procedures during general anesthesia with total intravenous technique.
The main question it aims to answer is:
\- Does topical lidocaine sprayed at the laryngeal inlet combined with the endotracheal tube cuff have more effect on stabilizing hemodynamic responses to laryngoscopy and intubation than intravenous lidocaine, in neurosurgical patients who undergo general anesthesia with total intravenous technique?
Participants will be recruited and randomized to receive either lidocaine spray (Group SL) or intravenous lidocaine (group IL) to blunt hemodynamic response to laryngoscopy and intubation.
