Insights
Heparin is no longer necessary for implanted vascular access device (IVAD) management. Evidence shows 0.9% sodium chloride flushes effectively prevent IVAD occlusion, reducing the need for alteplase.
Area of Science:
- Nursing Practice
- Vascular Access Device Management
- Evidence-Based Practice
Background:
- Heparin has been a standard flush solution for implanted vascular access devices (IVADs).
- Concerns exist regarding heparin's potential risks and the need for effective alternatives.
- Literature suggests saline may be a viable alternative for IVAD maintenance.
Purpose of the Study:
- To describe the implementation and outcomes of removing heparin from IVAD management.
- To evaluate the effectiveness of 0.9% sodium chloride as a replacement flush solution.
- To assess the impact on alteplase administration rates post-implementation.
Main Methods:
- Conducted an extensive literature search and appraisal to identify best practices.
- Implemented a nurse-led initiative to replace heparin with 0.9% sodium chloride for IVAD deaccessing.
- Utilized a pulsatile flushing technique with saline.
- Monitored alteplase administration rates as a key performance indicator.
Main Results:
- Successfully removed heparin from the IVAD deaccess protocol.
- 0.9% sodium chloride with pulsatile flushing proved effective in preventing occlusion.
- No statistically significant change in alteplase administration rates was observed 6 months post-implementation.
Conclusions:
- 0.9% sodium chloride alone is effective for IVAD lock maintenance.
- This evidence-based practice change demonstrates a safe and effective alternative to heparin.
- The findings support the use of saline for IVAD management, potentially reducing medication-related risks.
Abstract:
The objective of this article was to describe the implementation and outcomes of an evidence-based practice change to remove heparin from implanted vascular access device (IVAD) management. An extensive search of the literature was performed, and articles were appraised and synthesized to determine the best practice. A common theme emerged from the literature, showing that 0.9% sodium chloride alone can be as effective as heparin in preventing occlusion in IVADs. In this nurse-led initiative, heparin was successfully removed from the IVAD deaccess process and replaced with a 0.9% sodium chloride flush using a pulsatile flushing technique. Alteplase administration rates were used to measure success of the project, with no statistically significant change observed in alteplase rates 6 mo postimplementation. Successful implementation of this practice change demonstrates that 0.9% sodium chloride may be used for IVAD lock when deaccessing.
