Summary
Intraoperative autotransfusion (IAT) in urology is limited by contamination concerns. While IAT removed urine, it did not fully eliminate bacteria or cancer cells from blood mixtures.
Area of Science:
- Urology
- Transfusion Medicine
- Biomedical Engineering
Context:
- Intraoperative autotransfusion (IAT) is valuable but limited in urological surgery due to contamination risks.
- Concerns include contamination by urine, bacteria, or tumor cells, hindering widespread adoption.
- No prior studies experimentally assessed contamination protection during IAT in urology.
Purpose:
- To evaluate the efficacy of the Haemonetic Cell Saver in separating blood from urine, bacteria, and cancer cells.
- To assess the safety and feasibility of IAT in urological procedures with potential contamination.
Summary:
- Three experiments tested the Haemonetic Cell Saver with blood mixed with urine, bacteria, or cancer cells.
- The machine completely removed urine constituents but incompletely removed bacteria and did not remove cancer cells.
- Biochemical, bacteriological, and cytological analyses confirmed the separation effectiveness and limitations.
Impact:
- IAT in urological operations should be restricted to patients with sterile urine and no tumor cells in the operative field.
- Findings highlight the need for careful patient selection to mitigate risks associated with IAT.
- This study provides critical data for refining IAT protocols in urology.
