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

Overview

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

  • Device: Channeled blade
    • In the present group, a tracheal tube was launched in the channel of the blade before tracheal intubation
  • Device: Non-channeled blade
    • In the present group, a tracheal tube was not launched in the videolaryngoscope blade before tracheal intubation

Arms, Groups and Cohorts

  • Experimental: Channeled group
    • Group of patients using a channeled blade for videolaryngoscopy
  • Active Comparator: Non-channeled group
    • Group of patients using a non-channeled blade (standard type) for videolaryngoscopy

Clinical Trial Outcome Measures

Primary Measures

  • Intubation time
    • Time Frame: Immediately after tracheal intubation completed
    • the time for tracheal intubation

Secondary Measures

  • First-pass rate
    • Time Frame: Immediately after tracheal intubation completed
    • the success rate of tracheal intubation with one attempt
  • Intubation-related complications
    • Time Frame: within 24 hours after surgery
    • the incidence of overall complications related with tracheal intubation
