- To emphasize the integrated nature of catheter systems.
- To underscore the combined role of technique and technology in effective flushing.
Main Methods:
- This study reviews the components of catheter flushing technology.
- It examines flush solutions, delivery systems, and catheter design.
- The focus is on the interplay between technique and technology.
Main Results:
- Effective catheter flushing depends on a systems approach.
- Each component, from flush solution to catheter design, impacts patency.
- Successful flushing requires synergy between nursing technique and technological elements.
Conclusions:
- Catheter flushing is a complex process requiring a holistic view.
- Understanding the interaction between technique and technology is vital for maintaining catheter patency.
- Optimizing catheter flushing protocols can improve patient outcomes.
Abstract:
Maintenance of catheter lumen patency is an ongoing challenge. Catheter flushing is the primary nursing intervention used to prevent lumen occlusion from thrombotic and precipitate causes. The catheter and all devices attached to it must be regarded as a system in which each component directly affects the others. The technology of catheter flushing includes the flush solution itself, the source of these solutions, syringe design, mechanical pumps, needleless injection systems, and the design of the catheter. Effective catheter flushing is a combination of a technique and technology that requires an understanding of how both must work together.
