Comparison of Application Effects Between Long- and Standard Short- Peripheral Venous Catheters

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. The study nurse will work with the responsible physician to assess the eligibility for enrollment and sign the informed consent. Were randomly assigned to the control group (to receive a new 24G/22G (0.7mm\*19mm/0.9mm\*25mm) short PIVC (closed needle protected venous catheter system) puncture) or the intervention group (to insert a new 3F (8cm) or 4F(10cm) long PIVC) for daily routine maintenance until catheter removal, General demographic data, laboratory-related data, catheter-related data, catheter-related complications (unplanned extubation, phlebitis, catheter blockage, catheter-related thrombosis, catheter-related bloodstream infection, exudation, etc.) and patient satisfaction were collected.
