Video games are activities that require actively hand-eye coordination and where 3D thinking is at the forefront.

During the teaching of both laparoscopic surgery and robotic surgery techniques, it was revealed by the studies that the participants who played video games completed the trainings more easily and the success rate increased.

In a study comparing fiberoptic intubation success, anesthesia assistants playing video games had higher successful intubation rates and shorter intubation times in the first attempt.

Video stylets are newly developed devices that allow the use of video technology in airway management.

It has a camera at the end and a monitor to which the image is transferred. By transferring the real-time view of the airway structures, tracheal intubation increases the success rate and shortens the intubation time.

In order to determine whether video game playing has positive effects on videostylet use,ıt was aimed to compare the performances of the assistants who did play with the video game assistants.

Anesthesiology assistants will be questioned about whether participants have played video games before or not.

Participants will be divided into two different groups as those with and without prior video game experience.

Video game will be played for those who have previous experience for 5 days via 0.5 hour mobile phone (Pubg mobile).No games will be played on the other group.

Then, all participants will be trained on the video stylet.

Within the scope of this training, all participants will watch videos about 1-Video stylet application.

2-Verbal explanation will be made by the responsible and investigators of the study 3- All participants will practice on the model first

4-Responsible investigators will practice and show on the real patient.

5-Then all participants will perform the application on the real patient under the supervision of responsible and investigators.

Tracheal intubation time, success rate, number of interventions will be recorded by responsible and investigators.

Inclusion Criteria:

• Mallampati score I-II
• Cormack-Lehane score I-II
• ASA physical status I-II
• who required endotracheal intubation for elective surgery

Exclusion Criteria:

• Pregnancy
• Mallampati score III-IV
• Cormack-Lehane score III-IV
• ASA physical score III-IV
• sternomental distance < 12.5 cm
• mandibular-hyoid distance < 6 cm

Patients who will undergo general anesthesia under elective conditions and have endotracheal intubation and who do not meet difficult intubation criteria will be included in the study.
