Brief summary

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.

Detailed description

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 personal 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.

Interventions

DEVICEMacintosh laryngoscope

During the pre-implementation period (6 months), the 35 assigned attending anesthetists will perform all tracheal intubations in the operation room according to the standard of care using the standard Macintosh direct laryngoscope as a first intubation option

During the post-implementation period (6 months), the 35 assigned attending anesthetists will perform all tracheal intubations using their personal McGrath Mac videolaryngoscope as a first intubation option.

Design outcomes

Primary

MeasureTime frameDescription
easy intubationduring intubationTo compare easy intubation in the two study periods. Easy intubation defined as intubation at the first attempt, modified Cormack-Lehane grades of I or IIa and absence of need of adjuvant airway devices for intubation. (percentage)

Secondary

MeasureTime frameDescription
Intubations at the first attemptduring intubationTo compare difference in the incidence of intubations at the first attempt in the two periods studied. (percentage)
Number of intubations attemptsduring intubationTo compare number of intubations attempts in the two periods studied
Modified Cormack-Lehane grade of glottic viewduring intubationTo compare Modified Cormack-Lehane grade of glottic view in the two periods studied Modified Cormack-Lehane grade of glottic view:I: full view of the glottis IIa: partial view of the glottis IIb: arytenoid or posterior part of the vocal cords just visible III: only epiglottis visible IV: neither glottis nor epiglottis visible
Need of adjuvant airway devices for intubationduring intubationTo compare need of adjuvant airway devices for intubation in the two periods studied airway devices for intubation: bougie, videolaryngoscope, others)
Complications during intubationParticipants will be followed from the beginning of the intervention to 30 minutes after the interventionTo compare percentage of complications associated with the intubation in the two periods studied
Overall success rate intubationDuring intubationTo compare the difference overall success rate intubation (percentage) with the first device used in each period
Need to change the device for intubationDuring intubationTo compare the need to change the device for intubation in the two periods studied
Operator-assessed subjective difficultyduring intubationTo compare degree of subjective difficulty experienced by the operator in the two periods studied. Subjective difficulty of intubation by means of a special analogue numerical scale from 0 to 10, where 0=no subjective difficulty and 10=maximal subjective difficulty
