Summary
This study introduces a novel erythropheresis technique for normovolaemic haemodilution before surgery. It offers advantages like improved asepsis and storage, making it a viable alternative for specific surgical cases.
Area of Science:
- Anesthesiology
- Transfusion Medicine
Context:
- Preoperative autologous blood donation is standard, but not always feasible.
- Normovolaemic haemodilution (NHD) is an alternative to minimize allogeneic blood transfusions.
- Erythropheresis offers a method for NHD, but requires optimized protocols.
Purpose:
- To describe and evaluate a specific NHD technique using erythropheresis and a specialized kit for orthopaedic surgery.
- To highlight the advantages of this technique over standard methods.
Summary:
- NHD was performed using erythropheresis 24-72 hours pre-surgery with a special kit, collecting red blood cells (RBCs) and replacing plasma with 4% albumin.
- The technique yielded 1-4 RBC packs with 75% hematocrit, stored for 10 days.
- Indications include expected blood loss of 1000-1500 ml or inability to donate preoperatively; contraindications are standard NHD contraindications.
Impact:
- This erythropheresis NHD technique offers excellent asepsis, 10-day storage, high hematocrit, and avoids anesthetic drugs in collected products.
- It maintains hemodynamic stability during anesthesia and saves time for surgical teams.
- The authors' experience suggests this method partially replaces conventional NHD techniques in orthopaedic surgery.
