Normovolaemic haemodilution using dextran 70 in thoracic surgery
Summary
Normovolaemic haemodilution significantly reduced donor blood use and improved acid-base balance in thoracic surgery patients. This technique offers a viable alternative to donor blood transfusion, especially when supply is limited or disease transmission risks are high.
Area of Science:
- Anesthesiology
- Transfusion Medicine
- Surgical Innovation
Background:
- Elective thoracic surgery often necessitates significant blood transfusions.
- Donor blood carries risks, including disease transmission and supply limitations.
- Alternative strategies to minimize donor blood exposure are clinically relevant.
Purpose of the Study:
- To evaluate the efficacy of normovolaemic haemodilution in reducing donor blood usage during thoracic surgery.
- To compare acid-base status and blood loss in patients undergoing normovolaemic haemodilution versus standard anesthesia.
- To assess the impact of dextran 70 on clotting time in this context.
Main Methods:
- Normovolaemic haemodilution was performed on 10 patients undergoing elective thoracic surgery.
- A control group of 10 patients received standard anesthesia for similar procedures.
- Blood loss, cell loss, donor blood requirements, and acid-base changes were measured and compared.
Main Results:
- Patients undergoing normovolaemic haemodilution used significantly less donor blood compared to the control group.
- Normovolaemic haemodilution resulted in a more satisfactory acid-base status.
- Dextran 70 did not adversely affect the crude clotting time.
Conclusions:
- Normovolaemic haemodilution is a feasible and effective alternative to donor blood transfusion for elective thoracic surgery.
- This method offers advantages in managing blood loss and acid-base balance.
- It is particularly beneficial during blood shortages or when minimizing transfusion-related risks is paramount.
