•
Have patient lift his/her head from the bed to define the
sternomastoid muscle. Catheterization will be performed at
the apex of a triangle formed between the two heads of the
sternomastoid muscle. The apex should be approximately three
finger breadths above the clavicle. The carotid artery should be
palpated medial to the point of catheter insertion.
•
Note the position of the subclavian vein, which is posterior
to the clavicle, superior to the first rib, and anterior to the
subclavian artery. (At a point just lateral to the angle made
by the clavicle and the first rib.)
WARNING:
•
Patients requiring ventilator support are at increased risk of
pneumothorax during subclavian vein cannulation, which may
cause complications.
•
Extended use of the subclavian vein may be associated with
subclavian vein stenosis.
