Single and double developing lines improve ultrasound-guided radial artery catheterization in obese patients: A randomized controlled trial
Authors' 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.
Study context
- Population
- Obese patients undergoing radial artery catheterization
- Participants
- 240 patients
- Comparison
- Acoustic shadowing ultrasound guidance with single or double developing lines vs none
- Primary endpoint
- First-attempt success rate
Methodological detailsthree-arm
- Three-arm
Primary result
As reported in the abstract
P = 0.001
Secondary outcomes
Procedure time to success at first attempt · across 3 groups
P < 0.001
Procedure time to success at first attempt
- No significant difference between single and double
Safety
Overall complications (vasospasm and hematoma) · across 3 groups
P = 0.001
Overall complications (vasospasm and hematoma)
- No significant difference between single and double
