McGrath vs. C-MAC Video Laryngoscopy Comparison in Endotracheal Tube Insertion

Study Overview
=================
Brief Summary
-----------------
Tracheal intubation is commonly performed using a standard Macintosh blade, but recently there has been advanced technology using video laryngoscopy (VL).In this modern era, there are various types of available VL to make it easier for anesthesiologists to perform intubation, especially in patients with difficult airway anatomy. Various studies showed different results regarding the effectiveness of both C-MAC® and McGrath®, by assessing the comparison of the effectiveness, valuable information will be obtained for further consideration by experts in choosing the best tools in the future.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Intubation time | Time required to perform intubation until endotracheal tube is properly positioned | From first intubation attempt until successful intubation, an average of one minute | 
| Ease of intubation | Difficulty level of intubation, scores 1-2, 1=effortless, 2=difficult | From first intubation attempt until successful intubation, an average of two minutes | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Number of intubation attempts | The number of times required for a successful intubation | From first intubation attempt until successful intubation, an average of one minute | 
| Glottic visualization | Visualization of glottic assessed by the POGO (Percentage of Glottis Opening) score, 1=best, 4=worst | During first intubation attempt, an average of 30 seconds | 
| Complications of intubation | Includes orotracheal trauma, presence of blood in the blades, laryngospasm, bradycardia | From first intubation attempt until successful intubation, an average of one minute |
