Purpose: The aim of this study was to verify the necessity of endotracheal intubation through video laryngoscope and to provide basic data to inform the provision of video laryngoscope education. Methods: Eighty paramedic students participated in this study. A survey was conducted from November 5, 2018 to December 7, 2018. Data were analyzed with independent t-tests, and the chi-squared test. Results: The video laryngoscope is a highly usable instrument that can easily be applied during training. The instrument provides better visual evaluation of the normal airway (p=.004), the airway in case of cervical collar and head fixation (p=.000), and the airway in case of tongue edema (p=.000). The time of endotracheal intubation in the normal airway was significantly less with the video laryngoscope compared with the direct laryngoscope. The success rate of tracheal intubation was significantly higher in the video laryngoscope group than in the direct laryngoscope. Conclusion: This study suggests the necessity of education on endotracheal intubation through video laryngoscope in the professional airway maintenance training course of emergency department students. The video laryngoscope is easier to apply than the direct laryngoscope in cases of intubation in various clinical situations.
