Brief Summary

Optimal patient head and neck position when performing videolaryngoscopy for endotracheal intubation has not yet been established.The investigators aim to assess the effect of two different positions on the laryngeal view obtained and success of tracheal intubation during videolaryngoscopy with two commercially available and well established videolaryngoscopes.

Conditions

Head and Neck Position for Intubation

Keywords

Head Neck Position Videolaryngoscopy

Outcome Measures

Primary Outcomes (1)

• Optimal Head and Neck Position during Videolaryngoscopy

  This will be assessed using a Difficult Intubation Scale Score for each of the 2 videolaryngoscopes used in the study, which will be assessed in both neutral and sniffing positions.

  6 months

Secondary Outcomes (2)

• Laryngoscopy Time

  Less than 1 minute

• Intubation Time

  Less than 1 minute
