Abstract:
The central venous access device (CVAD) is widely used in infusion of intravenous high nutrient solution, chemotherapy drugs, rapid infusion, blood transfusion, etc. CVAD is left in the patient′s blood vessels for a long time, although it has certain advantages in intravenous therapy, but also risks associated with it. In the past 20 years, many studies have focused on the mechanism of CVAD on vascular injury, trying to explore its mechanism from a different perspective at the microscopic level of pathophysiology. This article will review the three aspects of acute damage to the blood vessel caused by CVAD catheterization and chronic changes caused by indwelling catheters, analysis of the causes of vascular injury caused by CVAD catheterization, and research on preventing vascular injury caused by CVAD catheterization, aiming at providing reference for clinical intravenous therapy.
