Clinical Trial Summary

A randomized controlled prospective study of laryngoscopy and intubation success comparing direct laryngoscopy and the McGrath® Mac videolaryngoscope.


Description:

As airway management continues to evolve the investigators do not have an accurate statement of the success of direct laryngoscopy in daily clinical practice. The use of videolaryngoscopy is increasing as a technique for rescue intubation as well as for elective intubation. Current airway management guidelines recommend video-assisted laryngoscopy as a choice for basic airway management. This is a proposed comparison study of a video laryngoscope, use in the daily anesthesia practice, and its likely increased success compared to direct laryngoscopy. An international, multi-center, prospective randomized comparative trial (RCT) is proposed testing the superiority of oral tracheal intubation with the McGrath® MAC versus conventional laryngoscope in adult patients under general anesthesia.
