Summary
The new Xtra cell saver offers an improved user interface and data management system, enhancing data quality for electronic perfusion data management. It also achieved a higher hematocrit yield compared to traditional methods.
Area of Science:
- Biomedical Engineering
- Medical Devices
- Cardiovascular Surgery
Background:
- Declining donor blood supplies and rising transfusion costs necessitate alternatives like cell salvage.
- Transfusions are linked to higher mortality rates in cardiac patients, increasing the need for advanced cell salvage technology.
- The Xtra represents the first new cell saver model since 2001, coinciding with the growing demand for electronic perfusion data management (EPDM).
Purpose of the Study:
- To evaluate the usability and effectiveness of the new Xtra cell saver.
- To assess the capabilities of its integrated data management system (DMS) for EPDM.
- To compare the hematocrit yield of the Xtra's proprietary protocol (Popt) against a standard team protocol.
Main Methods:
- User interface (UI) and data management system (DMS) usability assessment.
- Comparison of data compilation efficiency and quality between the Xtra's DMS and traditional methods.
- Quantitative analysis of processed blood hematocrit levels using the Xtra's Popt protocol versus a custom protocol.
Main Results:
- The Xtra's UI was user-friendly, and its DMS facilitated comprehensive data management and central compilation, reducing data redundancy and inconsistency.
- The Popt protocol resulted in a higher '1st bowl' hematocrit (59.1% vs. 57.3%) and a 0.68% higher overall end-product hematocrit compared to the team's protocol.
- The Popt cycle time averaged 330 seconds, slightly longer than the team's protocol (approx. 300 seconds).
Conclusions:
- The Xtra cell saver is poised to lead the next generation of cell salvage technology with its advanced UI and DMS, supporting robust EPDM.
- The integrated DMS enhances data integrity and research potential, crucial for future-proofing cell salvage.
- The manufacturer's Popt protocol demonstrated superior hematocrit recovery, positioning the Xtra as a significant advancement for perfusion and cardiac surgery.
