Brief Summary

The investigators aimed to evaluate the predictive factors for successful videolaryngoscopic intubation without stylet.

Conditions

Intubation; Difficult or Failed; Videolaryngoscopy

Outcome Measures

Primary Outcomes (1)

• 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 Outcomes (4)

• Success rate of videolaryngoscopic intubation without stylet using BURP maneuver after failure of the first attempt

  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

  From the start of endotracheal intubation to 120 seconds

• Incidence of successful endotracheal intubation after the failure of the third attempt using stylet

  From the start of endotracheal intubation to 120 seconds

• Time to completion of endotracheal intubation

  From the start of endotracheal intubation to 120 seconds

Eligibility Criteria

• Age: 19 Years+
• Sex: all
• Healthy Volunteers: No
• Age Groups: Adult (18-64), Older Adult (65+)
• Sampling Method: Probability Sample
