Superficial Forearm Veins Compressibility and Width Clinical Trial
Official title:
Effect of Double Tourniquet Technique on Width and Compressibility of Superficial Veins of Forearm
Vein compressibility will be assessed after light pressure applied with the ultrasound probe. Vein compressibility will be graded as 3 (100% compressed), 2 (50-100 compressed), and 1 (less than 50% compressed). After baseline measurements were taken, a proximal tourniquet will be applied to mid-arm. Repeated measurements of depth, width, and compressibility will be taken one minute after the tourniquet was applied. Same measurements will be repeated again with second tourniquet applied 1 cm distal to the first tournique.
