A comparison of tracheal intubation in the simulated unstable cervical spine: McGrath videolaryngoscope versus Macintosh laryngoscope

In patients with a simulated unstable cervical spine, does laryngoscopy with a McGrath videolaryngoscope versus a Macintosh laryngoscope result in faster intubation, better laryngoscopic view and reduced intubation difficulty?

Brief summary

The aim of this project is to determine if the McGrath laryngoscope makes insertion of a breathing tube easier and safer compared to the conventional Macintosh laryngoscope. This procedure is done after the anaesthetic has started (you will be asleep when the breathing tube is put in). It is important to investigate better laryngoscopes for insertion of the breathing tube because sometimes this procedure can be more challenging than usual, especially if the patient has a neck injury and their neck must be held still during the procedure. In this setting, certain laryngoscopes may make the procedure easier by providing a better view of the larynx. There is evidence to suggest that the McGrath laryngoscope can make breathing tube insertion easier than when the conventional Macintosh laryngoscope is used.

Interventions

Intubation with a McGrath videolaryngoscope. Intubation involves passing an endotracheal tube into the trachea to enable ventilation during surgery. Evidence suggests that the McGrath videolaryngoscope provides an improved view of the larynx to enable safe passage of the tracheal tube. Duration of laryngoscope will be approximately 30-60 secs. Intubation will take place after induction of anaesthesia.
