Brief summary

The main objective of this study is to compare the proportion of tracheal intubations for which more than one person is necessary when using the McGRATH® MAC videolaryngoscope.

Detailed description

Videolaryngoscopes, such as McGRATH® MAC videolaryngoscope, are used to facilitate tracheal intubations. This study is designed to evaluate the proportion of cases requiring more than one member of the anesthesiology team when the video feature of McGRATH® MAC is available during laryngoscopy in a population of patients without a predicted difficult intubation (Arne's score \<11). General anesthesia from induction until tracheal intubation is recorded on a video for further analysis. Analysis includes characteristics of intubation, patient's monitoring and cooperation between anesthesiologists in two groups. In the control group, the screen of the McGRATH® MAC videolaryngoscope is hidden. In the experimental group, the McGRATH® MAC videolaryngoscope is used with its video feature.

Inclusion criteria

* Aged 18 years old minimum * Requiring general anesthesia and orotracheal intubation with a single lumen tube * Having signed an inform consent form * Having a telephone and agreeing to communicate their phone number * Benefiting from a social insurance scheme or beneficiary

Exclusion criteria

* Pregnant or breast-feeding women * Patients taken care in ambulatory surgery who could not be contacted within 24 hours following surgery * Patients having a predicted difficult intubation (Arné's score ≥ 11) or predicted difficult mask ventilation * patients requiring a rapid-sequence intubation * patients for whom general anesthesia using sufentanil, propofol, atracurium or rocuronium is not suitable.

Design outcomes

Primary

MeasureTime frameDescription
Number of people needed for tracheal intubation when the video feature of McGRATH® MAC videolaryngoscope is available30 minutesIntubation is video and audio recorded for further analysis. The availability of the video feature of McGRATH® MAC is hidden from the recording. Only the number of people required and the intubation characteristics can be seen on the video.

Secondary

MeasureTime frameDescription
Cooperation between members of the anesthesiology team during intubation30 minutesBased on the video recording: Use of the Kraus Scale (based on Kraus M, Huang C, Keltner D: Tactile Communication, Cooperation and Performance. Emotion, 2010, 10, 745-9) evaluating communication and gestures within the team
Intubation difficulty Scale (IDS)30 minutes
Number of hands necessary for tracheal intubation30 minutesBased on the video recording: 2 hands when one person intubates by itself without any help, 3 or 4 hands when assistance is given by a second anesthesiologist. 5 to 6 hands when a third person is needed.
Time to intubate30 minutesBased on the video recording: from the entrance of the blade in the patient's mouth until the presence of the first capnogram
Perception of intubation difficulty by the operator30 minutesEvaluation on a scale between zero (no difficulty at all) to ten (extremely difficult)
Intubation failure30 minutesBased on the video recording
Arterial desaturation30 minutes maximumBased on the video recording: visualisation of a pulse oximetry inferior to 92%
Impact of videolaryngoscopy on hemodynamic variables30 minutesBased on the video recording: Blood pressure and heart beat on monitoring before and after video laryngoscopy
Evaluation of usual complications after tracheal intubation24 hoursSore throat or voice change noticed on day 1
Esophageal intubation30 minutesNo capnograms during mechanical ventilation once intubation is performed
