Research Progress on Nursing of Vascular Catheter-Associated Infection (VCAI)

The intravascular catheter (IVC) is a commonly used intravenous access for patients with various diseases. It can be used for intravenous infusion, blood transfusion, blood collection, or monitoring of hemodynamic changes in patients, grasp the progress of the patient’s disease, and is an indispensable treatment tool in clinical practice. The intravascular catheter has a longer indwelling time, which can reduce the pain of diagnosis and treatment for patients, and has higher advantages. However, prolonged catheterization can easily lead to vessel catheter-associated infection (VCAI), which can induce serious complications, affect the prognosis of the disease, increase the risk of death for patients, and also bring a great burden to the work of medical staff. There are many prevention and treatment measures for VCAI, such as reasonable selection of catheters, reasonable determination of intubation locations, and standardized nursing catheters. And with the continuous optimization of nursing technology, catheter coating technology or antibacterial solution sealing technology has become a new nursing method for the disease, which can effectively reduce the incidence of VCAI. This study comprehensively expounds on the concept, mechanism, risk factors, and preventive nursing measures of VCAI, in order to explore effective nursing plans for VCAI and improve the quality of nursing for patients with intravascular catheters.
