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.

Interventions

DEVICEChanneled blade

In the present group, a tracheal tube was launched in the channel of the blade before tracheal intubation

DEVICENon-channeled blade

In the present group, a tracheal tube was not launched in the videolaryngoscope blade before tracheal intubation
