Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Methods: One hundred patients scheduled for elective surgery under general anesthesia with endotracheal intubation were enrolled in this study. The patients were placed in the supine position with a neutral head position and without a pillow. The apex of the triangle formed by the sternal and clavicular heads of the sternocleidomastoid muscle and clavicle was marked (anatomical landmark point: AL point). The ultrasonography of the neck anatomy was performed, and a mark was placed at the central point of the IJV to the skin (ultrasonography point: US point). The other investigator measured the distances from the AL point to the US point (AL-US distance). The patient's head was then turned 30° to the left; the same procedure was repeated and the AL-US distance was again measured. The changes in AL-US distance were calculated.
