Research progress of application of different dressings in peripherally inserted central catheter maintenance (不同种类敷料在PICC维护中应用研究进展)

With the widespread development of peripherally inserted central catheter (PICC), a variety of dressing are available for clinic. Selecting appropriate dressings, mastering the operation standard process and correctly evaluating replacement time of dressing can effectively reduce the complications after PICC catheterization, which includes accidental prolapse, ectopic, bleeding, puncture site infection, etc. This paper discussed the characteristics, indications, operation procedures, indications of different dressings in PICC and the different choices to be taken based on patients' own conditions. Therefore, it provides reference for the selection, usage and maintenance of clinical PICC catheterization dressings.
