Invasive Blood Pressure Monitoring Using Ultrasound-guided Artery Cannulation Through the Distal Radial Artery Approach at the Anatomical Snuffbox Compared With the Conventional Artery Approach: A Randomized Controlled Trial
Authors' conclusion
Compared with conventional radial artery and dorsalis pedis artery cannulation, the anatomical snuffbox approach achieves comparable success rates, establishing it as a clinically viable alternative for invasive hemodynamic monitoring.
Study context
- Population
- Patients scheduled for invasive BP monitoring via arterial cannulation
- Participants
- 120 patients
- Comparison
- Group A vs Group B vs Group C
- Primary endpoint
- Coprimary: first-attempt success rate and puncture duration
Methodological detailsMay 1, 2023, to May 1, 2024
- May 1, 2023, to May 1, 2024
Primary result
As reported in the abstract
First-attempt success rate
- Puncture duration significantly shorter in Group B than Group A
- P = 0.001
- Puncture duration significantly shorter in Group B than Group C
- P = 0.001
