Artery Size Comparison Study in Young Children
This research examines whether the two main arteries in children's forearms (radial and ulnar arteries) are different sizes. Understanding these differences may help doctors place medical tubes more safely during surgery.
Summary written for real people, not researchers, by Clin2.
Who can take part
- Child is scheduled for surgery requiring general anesthesia (sleep medicine during the operation)
- Child is in generally good health or has only mild medical conditions (ASA score 1–3)
- Child has no known problems with blood vessel structure or development
- Child has never had a needle or tube placed in the radial or ulnar arteries before
- Child has no history of serious injury to the arms or hands
- Child has no conditions that affect how blood vessels grow or function (such as connective tissue disorders or severe heart disease)

This study uses ultrasound to look at the blood vessels in the hands of children before they have surgery. It helps doctors understand hand blood flow better, which can make procedures safer.
This study compares two ways to place a small tube in your arm artery during robot-assisted urologic surgery. It aims to see if a different location in your wrist keeps your blood pressure readings more stable.
This trial tests which technique works better for placing a small tube in the wrist artery for monitoring during heart surgery. It compares the standard method to one using ultrasound guidance to find the best approach for patients with difficult wrist arteries.
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 trial compares two sizes of small tubes (called sheaths) used during a heart procedure to open blocked arteries. The procedure is done through a tiny artery in your wrist, and the goal is to see if a smaller tube works just as well with fewer side effects.
This study compares measuring blood pressure through an arm artery (radial) versus a leg artery (femoral) during heart surgery that uses a heart-lung machine. The goal is to see which method works better and is safer for patients.
