Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| First-pass success rate of videolaryngoscopic intubation without stylet | An intubation attempt is defined as passing the laryngoscope blade between the patient's teeth. Duration of endotracheal intubation is defined from the moment the operator grasps the tube until the black line on the tube passes through the vocal cords | From the start of endotracheal intubation to 120 seconds | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Success rate of videolaryngoscopic intubation without stylet using BURP maneuver after failure of the first attempt | An intubation attempt is defined as passing the laryngoscope blade between the patient's teeth. Duration of endotracheal intubation is defined from the moment the operator grasps the tube until the black line on the tube passes through the vocal cords | From the start of endotracheal intubation to 120 seconds | 
| Incidence of using a stylet for the success of videolaryngoscopic intubation after the failure of the second attempt using the BURP maneuver | An intubation attempt is defined as passing the laryngoscope blade between the patient's teeth. Duration of endotracheal intubation is defined from the moment the operator grasps the tube until the black line on the tube passes through the vocal cords | From the start of endotracheal intubation to 120 seconds | 
| Incidence of successful endotracheal intubation after the failure of the third attempt using stylet | An intubation attempt is defined as passing the laryngoscope blade between the patient's teeth. Duration of endotracheal intubation is defined from the moment the operator grasps the tube until the black line on the tube passes through the vocal cords | From the start of endotracheal intubation to 120 seconds | 
| Time to completion of endotracheal intubation | An intubation attempt is defined as passing the laryngoscope blade between the patient's teeth. Duration of endotracheal intubation is defined from the moment the operator grasps the tube until the black line on the tube passes through the vocal cords | From the start of endotracheal intubation to 120 seconds |
