Short PIVC (intravenous indentation needle) accounts for more than 50% of clinical infusion tools, but long PIVC is rarely used and studied in China. This study aims to explore the application characteristics and application effects of long PIVC in China. It provides reference for the correct selection of infusion tools, and promotes the clinical application and promotion of new intravenous therapy tools.
