Abstract
This study identified current trends of research regarding the effectiveness of venodilation techniques, focusing on experimental design, measurement methods, and venodilation effects for verification of the effects of venodilation in venipuncture. We conducted our literature search based on Cooper’s integrated literature review method. Using key search terms “venodilation,” “vasodilation AND venipuncture,” and “ (vasodilation AND peripheral) AND catheterization” to search the Japan Medical Abstract Society website, CINAHL, and PubMed, we analyzed 10 Japanese and six international reports. More than 80% of the reports described application of a tourniquet and local warming. Vein cross-sectional area and diameter increased, whereas vein depth decreased ; moreover, venipuncture success rate increased and needle insertion time was shortened by venodilation techniques. However, there were differences in methods among some reports, such as implementation time and tools, even when using the same venodilation techniques. Therefore, we conclude that is difficult to directly compare venodilation techniques among reports.
