Detaljeret beskrivelse
Background: This study was performed to ultrasonographically demonstrate the changes in relationship between the right IJV and an anatomical landmark in two different head positions: neutral and rotational.
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.

|
anatomical landmark point (AL) - ultrasonography point (US) distance(the distances from the AL point to the US point )
Tidsramme: within 5 minutes after itubation
|
The distance between the two points was considered "positive" if the US point was lateral to the AL point and "negative" if it was medial to the AL point.

within 5 minutes after itubation
