Endotracheal Intubation
Conditions
Brief summary
In this study, the investigators evaluate the effect of head positions (simple extension vs. sniffing position vs. head elevation) on endotracheal intubation using a videolaryngoscope.
Interventions
PROCEDUREendotracheal intubation
Endotracheal intubation is performed in simple head extension or sniffing position using a McGrath MAC videolaryngoscope.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Ease of intubation | 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
| Measure | Time frame | Description |
|---|---|---|
| Number of attempts | Procedure (At the end of endotracheal intubation) | Number of attempts for endotracheal intubation is recorded. |
| Intubation time | Procedure (During endotracheal intubation) | The time taken for endotracheal intubation is recorded. |
| Palatopharyngeal wall injury | Procedure (During endotracheal intubation) | Presence of palatopharyngeal wall injury is observed. |
| Percentage of glottic opening (POGO) score | Procedure (During endotracheal intubation) | POGO score is recorded during endotracheal intubation (0%: no visualization of glottic opening; 100%: entire visualization of the glottic opening). |
| Laryngeal pressure for exposure of the glottis | Procedure (During endotracheal intubation) | Requirement for laryngeal force to expose the glottis is recorded during videolaryngoscopy |
| Lifting force for advancing an endotracheal tube into the larynx | Procedure (During endotracheal intubation) | Requirement for lifting force is recorded during the advancement of the endotracheal tube into the larynx. |
| Laryngeal pressure for advancing an endotracheal tube into the larynx. | Procedure (During endotracheal intubation) | Requirement for laryngeal pressure is recorded during the advancement of the endotracheal tube into the larynx. |
| Lifting force for exposure of the glottis | Procedure (During endotracheal intubation) | Requirement for lifting force to expose the glottis is recorded during videolaryngoscopy |
