"Neutral Head Position" and "Head-lift Position" for Orotracheal Intubation With "Trachway" Intubating Stylet in Adults

Tri-Service General Hospital

About

The purpose of this study is to investigate two different patient's head and neck positions(neutral head position and head-lift position) for the effectiveness of orotracheal intubation with using the "Clarus Video System (Trachway®)" intubating stylet.

Full description

The sniffing position has traditionally been considered the optimal head position for direct laryngoscopy, However, it may aggravate cervical spine injury. The Trachway® video stylet is an intubating device that may avoid cervical movement during intubation. Nonetheless, the effectiveness of limited neck movement in patients with neutral head or head-lift position using the Trachway® video stylet remains unclear. The purpose of this study was to compare the intubation time of the two positions with the Trachway® video stylet.

Treatment:

Device: 7cm high pillow

Procedure: Head-lift position

Neutral Position

No Intervention group

Description:

The patients' head was placed in the neutral position and then the patient was intubated with Trachway by single-handed chin lift technique
