INSERTION SITES:
Warning: Physician discretion is strongly advised when inserting this
catheter in patients who are unable to take or hold a deep breath.
•
The patient should be in a modified Trendelenburg position, with
the upper chest exposed and the head turned slightly to the side
opposite the insertion area. A small rolled towel may be inserted
between the shoulder blades to facilitate the extension of the chest
area.
•
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.
Warning: Extended use of the subclavian vein may be associated with
subclavian vein stenosis.
