NCT07558694

Brief Summary

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.

Outcome Measures

Primary Outcomes (2)

  • Radial artery size

    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.

    Baseline

  • Ulnar artery size

    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.
