Comparison of the Intubation Condition Between Two Different Types of Video Laryngoscope Blades

Study Overview
=================
Brief Summary
-----------------
The present study compares two different types of videolaryngoscope blade, which is a channeled and non-channeled blade. The purpose of the study is to investigate the effect of the type of videolaryngoscope blade on the intubation condition.

Detailed Description
-----------------
In tracheal intubation for general anesthesia, one of the two types of the blade during a video laryngoscopy can be used, one is a channeled blade that has a channel for tracheal tube launching, the other is a non-channeled blade. In the present study, the outcomes by using two types of the videolaryngoscope blade such as the intubation condition, intubation time, first-pass rate, and the incidence of intubation-related complications were compared.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: Channeled group<br>Group of patients using a channeled blade for videolaryngoscopy | Device: Channeled blade<br>* In the present group, a tracheal tube was launched in the channel of the blade before tracheal intubation<br>|
