Settings: Single ICU in Poland, randomized trial

Participants: intubated patients who needed arterial catheter placement. Patients who had adequate access to one axillary and one femoral artery were eligible.

Patients were randomized 1:1 for axillary or femoral artery cannulation.

Outcome measurement: Primary outcome was cannulation success rate. Secondary outcomes were first pass success rate, number of attempts.

Study Results:

• A total of 109 patients with data: 55 patients in the Axillary group vs. 54 for femoral group.
• Cannulation success rate for axillary group was 96.4% vs. 96% for femoral group
• First pass success rate for Axillary group was 69% vs. Femoral group of 74% (p=0.56)
• 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.

Discussion:

• 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.
• 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.
• There was overall low rate of complications.

Conclusion:

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.
