Arm && Interventions

Group	Intervention	Description
Head elevated position	endotracheal intubation	After induction of anesthesia, endotracheal intubation was performed in a head elevated position with a pillow using a McGrath MAC videolaryngoscope.
Simple extension	endotracheal intubation	After induction of anesthesia, endotracheal intubation was performed in simple extension without a pillow using a McGrath MAC videolaryngoscope.
Sniffing position	endotracheal intubation	After induction of anesthesia, endotracheal intubation was performed in a sniffing position using a McGrath MAC videolaryngoscope.

Primary Outcome Measures

Name	Time	Method
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 Outcome Measures

Name	Time	Method
Number of attempts	Procedure (At the end of endotracheal intubation)	Number of attempts for endotracheal intubation is recorded.
Laryngeal pressure for exposure of the glottis	Procedure (During endotracheal intubation)	Requirement for laryngeal force to expose the glottis is recorded during videolaryngoscopy
Palatopharyngeal wall injury	Procedure (During endotracheal intubation)	Presence of palatopharyngeal wall injury is observed.
Lifting force for exposure of the glottis	Procedure (During endotracheal intubation)	Requirement for lifting force to expose the glottis is recorded during videolaryngoscopy
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).
Intubation time	Procedure (During endotracheal intubation)	The time taken for endotracheal intubation is recorded.
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.
