About

In the case of tracheal intubation using a video laryngoscope, both techniques, one is 'conventional technique' in which intubation is performed by placing the blade tip on the vallecula and the other is 'sliding technique' performed by sliding the blade under the epiglottis, are commonly conducted by anesthesiologists. Investigators would like to compare if the sliding technique can improve the condition of tracheal intubation in patients wearing semi-rigid neck collars in cervical spine surgery.

Full description

For patients who need to limit the movement of the cervical spine, the tracheal intubation becomes difficult because the head must be positioned in the neutral position. Most of all, with a semi-rigid neck collar that maintains the neutral position of the head and neck, movement is limited and the mouth is not well-opened make the environment of tracheal intubation worse, which result in hypoxia or throat complications related to general anesthesia. Fortunately, it is possible that the development of video laryngoscope assists tracheal intubation easier for patients who have the limited movement of the cervical spine. However, the preferred intubation style and instrument selection for each operator are varied; the established method is required. In the case of tracheal intubation using a video laryngoscope, both techniques, one is 'conventional technique' in which intubation is performed by placing the blade tip on the vallecula and the other is 'sliding technique' performed by sliding the blade under the epiglottis, are commonly conducted by anesthesiologists. Investigators would like to compare if the sliding technique can improve the condition of tracheal intubation in patients wearing semi-rigid neck collars in cervical spine surgery.

178 participants in 2 patient groups

Conventional Intubating Technique

No Intervention group

Description:

'Conventional technique' means that endotracheal intubation is performed with the videolayngoscope blade lifting up the epiglottis.

Sliding Intubating Technique

Experimental group

Description:

'Sliding technique' means that endotracheal intubation is performed by sliding the videolayngoscope blade under the epiglottis smoothly.

Treatment:

Procedure: Sliding Intubating Technique
