What is this trial about?
Patients were randomly divided into two groups: ultrasound-guided (US-guided) in-plane distal
radial access (IP-DRA) and in-plane proximal radial access (IP-PRA) catheterization.
For IP-DRA , a linear transducer is placed in the radial fossa, which is known as the
snuff-box. After obtaining a long-axis view of the radial artery ,the needle is inserted in
the midpoint of the small footprint transducer. Then,the needle is advanced under real-time
US guidance until visualizing the tip of the needle inside the artery .
For IP-PRA , a linear transducer is placed in the standard conventional forearm radial.
After obtaining a long-axis view of the radial artery ,the needle is inserted in the midpoint
of the small footprint transducer. Then,the needle is advanced under real-time US guidance
until visualizing the tip of the needle inside the artery .
