Treatment and study plan

Endotracheal Intubation

Procedure

Endotracheal intubation is performed in simple head extension or sniffing position using a McGrath MAC videolaryngoscope.

Primary outcomes

  1. Ease of intubation

    Time frame: Procedure (During endotracheal intubation)

    Ease of endotracheal intubation is assessed using the intubation difficulty scale.

    Intubation difficulty scale includes number of attempts, number of operators, number of alternative techniques, glottic opening and so on.

Secondary outcomes

  1. Percentage of glottic opening (POGO) score

    Time frame: Procedure (During endotracheal intubation)

    POGO score is recorded during endotracheal intubation (0%: no visualization of glottic opening; 100%: entire visualization of the glottic opening).

  2. Number of attempts

    Time frame: Procedure (At the end of endotracheal intubation)

    Number of attempts for endotracheal intubation is recorded.

  3. Intubation time

    Time frame: Procedure (During endotracheal intubation)

    The time taken for endotracheal intubation is recorded.

  4. Palatopharyngeal wall injury

    Time frame: Procedure (During endotracheal intubation)

    Presence of palatopharyngeal wall injury is observed.

  5. Lifting force for exposure of the glottis

    Time frame: Procedure (During endotracheal intubation)

    Requirement for lifting force to expose the glottis is recorded during videolaryngoscopy

  6. Laryngeal pressure for exposure of the glottis

    Time frame: Procedure (During endotracheal intubation)

    Requirement for laryngeal force to expose the glottis is recorded during videolaryngoscopy

  7. Lifting force for advancing an endotracheal tube into the larynx

    Time frame: Procedure (During endotracheal intubation)

    Requirement for lifting force is recorded during the advancement of the endotracheal tube into the larynx.

  8. Laryngeal pressure for advancing an endotracheal tube into the larynx.

    Time frame: Procedure (During endotracheal intubation)

    Requirement for laryngeal pressure is recorded during the advancement of the endotracheal tube into the larynx.
