Title: Infraclavicular, Ultrasound-Guided Percutaneous Approach to the Axillary Artery for Arterial Catheter Placement: A Randomized Trial<br/>Author: Quincy Tran<br/><a href='http://umem.org/profiles/faculty/1281/'>[Click to email author]</a><hr/><p>
<strong>Settings</strong>: Single ICU in Poland, randomized trial</p>
<p>
<strong>Participants</strong>: intubated patients who needed arterial catheter placement. Patients who had adequate access to one axillary and one femoral artery were eligible.</p>
<p>
Patients were randomized 1:1 for axillary or femoral artery cannulation.</p>
<p>
<strong>Outcome measurement</strong>: Primary outcome was cannulation success rate. Secondary outcomes were first pass success rate, number of attempts.</p>
<p>
<strong>Study Results</strong>:</p>
<ul>
<li>
A total of 109 patients with data: 55 patients in the Axillary group vs. 54 for femoral group.</li>
<li>
Cannulation success rate for axillary group was 96.4% vs. 96% for femoral group</li>
<li>
First pass success rate for Axillary group was 69% vs. Femoral group of 74% (p=0.56)</li>
<li>
Total number of procedural complications (puncture of opposite wall of artery, puncture of adjacent vein, periarterial extravasation, ischemia of extremity) was non-statistically different between groups.</li>
</ul>
<p>
<strong>Discussion</strong>:</p>
<ul>
<li>
There was higher rate of dysfunction of arterial pressure curve among Axillary group (15%) vs. femoral group (2%, P = 0.016). The reason for this finding is not quite clear.</li>
<li>
Needle visibility was worse with the femoral group. There were 75% patients with excellent and good view for the Axillary group, vs. 24% for the femoral group. This could be due to the difference between out-of-plane cannulation for femoral group vs. in-plane cannulation for axillary group.</li>
<li>
There was overall low rate of complications.</li>
</ul>
<p>
<strong>Conclusion</strong>:</p>
<p>
Ultrasound-guided cannulation of the axillary artery via the infraclavicular route is non-inferior to the cannulation of the common femoral artery. When cannulation of the radial or femoral artery is not available, we can consider axillary artery via the infraclavicular approach.</p>
