Observational Study of Radial and Ulnar Artery Size in Young Children

This observational study is looking at the size of two important blood vessels in the arm, the radial artery and ulnar artery, in young children aged 2 to 9 years old who are having surgery under general anesthesia. Researchers will use ultrasound to measure these arteries in both arms after anesthesia has started, but before the surgery begins. The main goal is to see if there are differences in the size of these arteries within one arm, and then compare them between the dominant and non-dominant arms. You could be eligible if you are having surgery and meet certain health criteria, but not if you have known blood vessel problems, a history of punctures in these arteries, or significant arm injuries. The study aims to enroll 100 participants.

Study design
This is an observational study involving 100 participants. It is not a treatment study, but rather focuses on collecting measurements.
What's involved
Your child would have ultrasound measurements of their arm arteries performed after anesthesia induction, before surgery starts.
Compensation
Not stated in the trial record.
Follow-up
Measurements are taken at Baseline (a single point in time).

Eligibility criteria

Inclusion

ASA 1-3 patients undergoing a surgical procedure requiring general anesthesia.

Exclusion

Patients with known abnormalities in their vasculature.

What this trial measures

  • Radial artery sizeBaseline

    The anterior posterior measurement and the lateral measurement of the radial artery in both the dominant and non-dominant arm will be measured using ultrasonography.

  • Ulnar artery sizeBaseline

    The anterior posterior measurement and the lateral measurement of the ulnar artery in both the dominant and non-dominant arm will be measured using ultrasonography.
