Condition Intervention
Anesthesia, General
Intubation
Behavioral: head position change

Further study details as provided by Soonchunhyang University Hospital:

Primary Outcome Measures:
  • anatomical landmark point (AL) - ultrasonography point (US) distance(the distances from the AL point to the US point ) [ Time Frame: within 5 minutes after itubation ] [ Designated as safety issue: Yes ]
    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.


Secondary Outcome Measures:
  • The average depth of the right IJV [ Time Frame: within 5 minutes after intubation ] [ Designated as safety issue: Yes ]
    measure the depth of the right IJV center in ultrasonography

Groups/Cohorts Assigned Interventions
neutral head position
supine with neutral head position
Behavioral: head position change
AL-US distance measure using the ultrasound in two different head position
head rotation
supine with 30° head rotation
Behavioral: head position change
AL-US distance measure using the ultrasound in two different head position

Detailed Description:

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.
