Abstract

Objective: Complications of peripheral venous infusion are an important problem that can lead to subcutaneous tissue damage. Although the select of vessels with high blood flow has been shown to have the potential to prevent complications, a method for measuring peripheral venous blood flow has not been established. <br>　This study aimed to verify the reliability and validity of blood flow measurement in the veins of the upper limb using ultrasonography with auto volume flow (AVF) function. <br>　Method: This observational study was involved eight healthy participants with 12 arms. Blood flow was measured in the basilic vein of the upper arm and forearm, the median cubital vein of the forearm, and the cephalic veins of the forearm. Measurements were performed using the portable ultrasound system by a trained nurse researcher. Intra-rater reliability was assessed by intraclass correlation coefficients (ICC). For concurrent validity, Pearson’s correlation coefficients were calculated between the manual measurement method and the AVF function. Known-group validity was assessed by comparing the blood flow volume in the basilic vein of the upper arm to that in the forearm veins. <br>　Results: The ICCs (1.1) of the manual procedure and AVF function were 0.91 and 0.92, respectively, and the ICCs (1.3) were 0.97 and 0.97, respectively (p < 0.01). A correlation was found between the manual procedure and the AVF function (r = 0.96, p < 0.01). Significant differences in blood flow were evident between the basilic vein of the upper arm and the forearm veins when using the AVF function (p < 0.01). <br>　Conclusion: This study demonstrated the reliability and validity of blood flow measurement in the upper limbs using the AFV function.
