Differences in Radial and Ulnar Artery Size in Young Children (NCT07558694)
Differences in Radial and Ulnar Artery Size in Young Children: Does Hand Dominance Impact the Differences?
🩺 Plain-English Summary (8th-Grade Level)
This is a prospective observational study that requires measurement of the size of both arteries in both upper extremities using ultrasound. These will be performed after the induction of anesthesia prior to the start of the surgical procedure. The primary objective of this study is to evaluate differences in the size of the radial and ulnar artery in a single extremity and then compared to the non-dominant extremity.
Who can join: To join this study, participants generally need to meet the listed inclusion criteria (1 items) and avoid the listed exclusions (6 items).
