Summary
The Sorensen autotransfusion unit is a practical tool for moderate bleeding, reducing homologous blood use. It showed minor lab value changes and is reliable for specific patient groups.
Area of Science:
- Cardiovascular Surgery
- Trauma Surgery
- Medical Devices
Context:
- Clinical application of the Sorensen autotransfusion unit since 1980 in Würzburg.
- Evaluation in 47 patients, including vascular, trauma, and specific arterial bleeding cases.
Purpose:
- To assess the practicability, advantages, and disadvantages of the Sorensen autotransfusion unit.
- To determine its clinical utility in reducing homologous blood transfusions.
Summary:
- The Sorensen autotransfusion unit demonstrated convenience, ease of use, and reliability.
- Minor decreases in hemoglobin, hematocrit, and platelets were observed, with stable coagulation parameters and organ function tests.
- Free hemoglobin was detected in three cases of extremely high-volume autotransfusions.
Impact:
- The unit is suitable for moderate hemorrhage, with hemothorax blood requiring anti-fibrinolytic therapy.
- Effective use can significantly contribute to saving homologous blood in specific surgical and trauma scenarios.
