Clinical Trial Summary

1. Airway length from the medial incisor to carina is divided into four segments ; the length from medial incisor to mouth angle, mouth angle to epiglottis, epiglottis to vocal cords and vocal cords to carina.

2. Determining the mean length of each segments with the direct laryngoscope, videolaryngoscope and fiberoptic bronchoscope at the time of endotracheal intubation.

3. Making a new formula to determine the proper individualized depth of intubation on the basis of the length of segments

4. Virtual experiment : comparing the new formula with conventional method of determining the depth of endotracheal intubation

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Comparison of Airway Length Between Male and Female	Airway length is defined the distance from medial incisor to carina. It is divided into four parts. It is medial incisor to mouth angle, mouth angle to epiglottis tip, epiglottis tip to vocal cords and vocal cords to carina.	Endotracheal intubation time	No
Primary	Airway Length vs Height in Male		Endotracheal intubation time	No
Primary	Airway Length vs Height in Female		Endotracheal intubation time	No
Secondary	Comparison Between Conventional Method and Touch and Read Method for Risk Group of Male	Normal group is defined as the patients whose airway length from medial incisor to carina is below 25cm.; Conventional method : depth of intubation is 23cm at the medial incisor for male.; Touch and read method : depth of intubation is calculated as follow : length from mouth angle to epiglottis tip plus 12.5cm for male.	Endotracheal intubation time	No
Secondary	Comparison Between Conventional Method and Touch and Read Method for Normal Group of Male	Normal group is defined as the patients whose airway length from medial incisor to carina is over 25cm.; Conventional method : depth of intubation is 23cm at the medial incisor for male.; Touch and read method : depth of intubation is calculated as follow : length from mouth angle to epiglottis tip plus 12.5cm for male.	Endotracheal intubation time	No
Secondary	Comparison Between Conventional Method and Touch and Read Method for Risk Group of Female	Risk group is defined as the patients whose airway length from medial incisor to carina is below 23cm.; Conventional method : depth of intubation is 21cm at the medial incisor for female.; Touch and read method : depth of intubation is calculated as follow : length from mouth angle to epiglottis tip plus 11.5cm for female.	Endotracheal intubation time	No
Secondary	Comparison Between Conventional Method and Touch and Read Method for Normal Group of Female	Normal group is defined as the patients whose airway length from medial incisor to carina is over 23cm.; Conventional method : depth of intubation is 21cm at the medial incisor for female.; Touch and read method : depth of intubation is calculated as follow : length from mouth angle to epiglottis tip plus 11.5cm for female.	Endotracheal intubation time	No
