Q: While inserting axillary arterial line, it should be ideally placed
A) as high as possible within the axilla
B) at low as possible within the axilla
Answer: A
The axillary arterial line should be inserted as high into the apex of the axilla as possible by palpation, or ideally as visualized by ultrasound. The axillary fossa can be exposed well by abduction and external rotation of the arm. This is due to the fact that as at a higher level the axillary artery receives good collateral flow through thyrocervical trunk and subscapular artery. This reduces risk of ischemia.
