Ultrasound guidance for placing a wrist arterial line
This study compares two ways of using ultrasound to guide the placement of a small tube in the wrist artery (radial arterial line) for close blood pressure monitoring during surgery. It helps doctors find the best method to place the tube safely and with fewer complications.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are 18 years old or older.
- Your doctor plans to place a small tube in your wrist artery (radial artery) to closely watch your blood pressure during a surgery or procedure.
- You must have a healthy wrist area on the arm being used — no infection, burn, scar, or skin problem at the site.
- You have adequate blood flow to the hand, which will be checked with a simple test (Allen test) or ultrasound.
- You do not have a severe bleeding disorder, recent surgery on that arm, or a condition like a blocked artery or an arteriovenous fistula in that arm.
- You are not pregnant and are not allergic to the ultrasound gel used during the procedure.

This study compares two methods of placing a small tube (arterial line) in your wrist or arm to monitor blood pressure during heart surgery. Both methods use ultrasound to guide the tube, and the study aims to see which technique works better when the artery is hard to access.
This trial compares two methods of placing a small tube in an artery in the wrist to monitor blood pressure continuously during robotic urologic surgery. The goal is to see which method gives more stable and accurate readings when your arms are tucked at your sides.
This study tests a new laser-guided tool to help doctors place a small tube in the wrist artery of babies and young children during surgery. It aims to make the procedure faster and safer for your child.
This study compares two ways of accessing the heart's blood vessels through the wrist artery during a heart imaging procedure. Researchers will test whether using ultrasound to guide the needle improves the success and safety of the procedure.
This study looks at the sizes of two arteries in the wrist (the radial and ulnar arteries) in young children during surgery. It will help doctors understand normal sizes, which may improve how they place small tubes in arteries for monitoring during and after surgery.
This trial looks at using the ulnar artery in the wrist instead of the radial artery for heart catheterization or stent placement, when the radial artery on that side is blocked. It may be an option for people who cannot use the other arm's radial artery.
