McGrath Video Laryngoscope for All Intubations in the Operating Room

Tracheal intubation is a very common procedure performed in the operating room. The usual intubation technique in the operating room is based on direct laryngoscopy, using a standard Macintosh laryngoscope. Although in most patients there are no complications during intubation, more than 90% of difficult tracheal intubations in the operate room are unpredictable, and several authors, recommend the universal use of the videolaryngoscope for all intubations, using as the first intubation option regardless of whether the patient has predictors of a difficult airway or no.The authors do not know whether providing a own videolaryngoscope to each anesthesiologist to use as the first option for intubation in all patients who need it in the operating room improves the percentage of patients with easy intubation and decrease the incidence of complications.

The VIDEOLAR-SURGERY trial is a prospective, observational, open-label, multicenter study, with before-after analysis. Consecutive patients requiring tracheal intubation for an elective o urgent surgical intervention from a period of 14 months by one of the 35 researcher's anesthesiologists assigned will be recruited. In the pre-implementation period (6 months), the 35 anesthesiologists will perform all tracheal intubations using the standard Macintosh direct laryngoscope as a first intubation option. During the implementation period (2 months), a personal McGrath videolaryngoscope will be provided to each anesthesiologist to train in its use. During the post-implementation period (6 months), the 35 anesthesiologists will perform all tracheal intubations using their personal McGrath Mac videolaryngoscope as a first intubation option. The main objective is to evaluate whether the use of a own McGrath videolaryngoscope by anesthesiologists, as the first intubation option, improves the percentage of patients with easy intubation compared with the standard Macintosh laryngoscope. Secondary objectives are to compare incidence of first-attempt intubation, laryngoscopic vision, need of adjuvant airway devices, difficulty, and complications.
