Summary
Brief summary (as posted)
The goal of this RCT is to compare outcome with McGrath vs Macintosh laryngoscopes among patients undergoing thoracic surgery. The main questions it aims to answer are, 1. Rate of successful intubation at first attempt and 2. Time for intubation required with each device. Participants are required to sign the informed consent for, they will be placed in two groups, Group A: Macintosh (DL) Group B: McGrath (VL) Researchers will compare in Group A: Macintosh (DL) and Group B: McGrath (VL) the differences in rate of successful intubation at first attempt and time for intubation required with each device.
