A Comparison Between Using Video Stylet and Video Laryngoscope in Difficult Intubation of Traumatic Patients .


The aim of this study is to compare the visualization of the glottis, the time for tracheal intubation, the success rate of intubation, and the need for manoeuvres to optimize the view using video stylet or video laryngoscope in patients with expected difficult intubations.

Detailed Description

The airway, breathing and circulation support '' ABCs" of trauma resuscitation were born from the assumption that correcting hypoxemia and hypotension reduces morbidity and mortality. Definitive care for severely injured or polytrauma patients includes the ability to provide advanced airway management in a variety of settings: in the emergency department, 20% to 30% intubations are for trauma. Airway management in traumatic patient presents numerous unique challenges beyond placement of an endotracheal tube, without comes dependent on the provider's ability to predict and anticipate difficulty and have a safe and executable plan. In severely injured patients, the cervical spine must be protected by in-line immobilisation during airway management. If orotracheal intubation is required, then manual in-line stabilisation is recommended to facilitate tracheal intubation to secure a space for tongue displacement into the submandibular space. However, manual in-line stabilisation can make alignment of the oral, pharyngeal and laryngeal axes difficult, resulting in a poor direct laryngoscopic view and prolonging the intubation time. Video stylets, which are portable and easier to prepare than flexible fiberoptic bronchoscopes, could be better option for tracheal intubation in patient with cervical immobilization. Previous studies have shown the usefulness of video stylets for tracheal intubation in cervical immobilized patients. Video laryngoscopes provide a better laryngeal view. They are easy to use and have a high success rate and short intubation time in patients with predicted difficult airways. Successful use of video laryngoscopy is increasing for airway management of patients with trauma in the emergency department.


  • Device: Intubation
    • Using video stylet and video laryngoscope in difficult intubation in patients with trauma or suspected to be have difficult intubation.

Arms, Groups and Cohorts

  • Other: Group A
    • Group A will include 168 patients and will be intubated by the use of video stylet.
  • Other: Group B
    • Group B will include 168 patients and will intubated by the use of video laryngoscope

Clinical Trial Outcome Measures

Primary Measures

  • Comparison of success rate for the tracheal intubation in patients with anticipated difficult airways, demonstrating the non inferiority of video stylet efficacy compare to the most consolidated technique based on videolaryngoscope
    • Time Frame: 9 minutes
    • The success rate of the rigid fiberoptic stylet to perform tracheal intubation in patients with anticipated difficult airways [ Time Frame: up to a maximum of 3 attempts and up to 3 minutes from device insertion for each attempt (max 9 minutes) ] . success rate of the procedure defined as correct positioning of the tracheal tube in the trachea confirmed both endoscopically and through the capnographic curve end tidal carbon dioxide (Et CO2) time consumed to achieve a successful intubation by each device.

Secondary Measures

  • Average time of intubation procedure expressed in seconds [ Time Frame: up to 9 minutes ]
    • Time Frame: 9 minutes
    • Time in minutes measured from device insertion into the patient’s mouth until the endotracheal tube will be positioned into the trachea .
  • Development of any complications [ Time Frame: up to 12 hours measured from the insertion of the device ]
    • Time Frame: 12 hours
    • Occurrence of any complications or adverse event during the procedure (desaturation episodes, hemodynamic changes, oral-pharynx and larynx traumatism)
