• Status: Not yet recruiting
• Trial end date: 2025-09-09
• Target enrollment: 0
• Participant gender: All

Summary

The goal of this clinical trial is to test the effect of nebulized lidocaine on the hemodynamic response in the participant undergoing double-lumen endotracheal intubation.

The main question it aims to answer is to evaluate the changes in mean arterial pressure after intubation.

Participants will inhale 5ml of 2% lidocaine by nebulization15min before intubation.

Researchers will compare saline group to see if saline effects
