Major thrombotic and nonthrombotic complications. Loss of patency
Insights
Maintaining vascular access device and vein patency is crucial for infusion therapy. This review details causes, incidence, and prevention strategies for catheter and vein patency loss in clinical practice.
Area of Science:
- Vascular access and infusion therapy management.
- Clinical nursing and patient care.
Background:
- Vascular access device (VAD) and vein patency are essential for successful infusion therapy.
- Loss of patency can occur due to device insertion, maintenance, and patient-related factors.
Purpose of the Study:
- To review current information on causes, incidence, management, and prevention of VAD and vein patency issues.
- To provide insights for all clinical settings encountering these problems.
Main Methods:
- Literature review of recent information on catheter and vein patency.
- Synthesis of data on causes, incidence, management, and prevention strategies.
Main Results:
- Catheter patency loss is linked to insertion decisions and maintenance practices (infusion, flushing, dressing, removal).
- Vein patency loss is associated with insertion techniques, patient activity, and underlying medical conditions.
Conclusions:
- Understanding the multifactorial causes of patency loss is key to effective prevention and management.
- Implementing evidence-based strategies can improve infusion therapy outcomes by maintaining VAD and vein patency.
Abstract:
Patency of the vascular access device and the vein that houses the device is critical for the successful delivery of infusion therapy. Loss of catheter patency comes from decisions made during device insertion and from methods used for infusion, flushing, dressing, and removal. Loss of vein patency comes from insertion techniques, patient activity, anatomic and physiologic reasons, and the primary disease or underlying chronic diseases. This review provides the latest information on causes, reported incidences, management, and prevention of catheter and vein patency problems frequently encountered in all clinical settings.
