Single and double developing lines improve ultrasound-guided radial artery catheterization in obese patients: A randomized controlled trial - 22/03/23
Abstract |
Background |
Arterial catheterization is challenging in obese patients. The present study tested the hypothesis that ultrasound guidance with acoustic shadowing improves the success rate of radial artery catheterization in obese patients.
Methods |
240 obese patients were enrolled and were randomly assigned to three groups: control group, single developing line group, or double developing lines group. Patients underwent radial artery catheterization guided by acoustic shadowing ultrasound with none, single or double developing lines. The primary outcome was the first-attempt success rate. The secondary outcomes included the procedure time and complication rate.
Results |
In the single or double developing lines group, the success rate of radial artery catheterization at the first attempt was higher than in the control group (control vs. single vs. double, 71% vs. 90% vs. 91%, P = 0.001). Besides, the single and double developing lines groups had a shorter procedure time to success at the first attempt and a lower overall complication (vasospasm and hematoma) rate than the control group (procedure time: control vs. single vs. double, 63 s vs. 54 s vs. 40 s, P < 0.001; overall complication rate: control vs. single vs. double, 29% vs. 10% vs. 9%, P = 0.001). There was no significant difference in the first-attempt success rate, the procedure time to success within the first attempt, or overall complications’ rate between the single and double developing lines groups.
Conclusion |
Single and double developing lines improve first-attempt success rate and reduced the overall complications’ rate of ultrasound-guided radial artery catheterization in obese patients.
