Vascular access for venepuncture and peripheral intravenous cannulation is a common procedure within health care. First-attempt cannula insertion success rate has been found to be lower in some patient groups. Multiple unsuccessful cannulation attempts have negative impacts for both patients and practitioners. This article reports on research investigating the effectiveness of an innovative device called the Vacuderm—a single-use tourniquet with added manual vacuum pump—in increasing vein dimensions, temperature difference between vein and its surrounding and visual clarity through an additional effect of creating a vacuum on top of the tourniquet. A randomised crossover design was used in this study for looking at the vein visibility, dimensions and thermal behaviour using infrared thermography. Dorsal areas of both hands were assessed in a random crossover study of 20 healthy volunteers with and without the application of the Vacuderm. The results show significant increase in venous diameter and venous cross-sectional area with highly significant increase in vein clarity caused by using the Vacuderm, which creates a negative pressure for transient suction in addition to its vein occlusion effect.
