[Indication for prophylactic and therapeutic thrombocyte substitution]
Zeitschrift Fur Die Gesamte Innere Medizin Und Ihre Grenzgebiete
|July 15, 1982
Summary
Platelet transfusions are indicated for bleeding disorders or prophylactically to prevent life-limiting hemorrhages. Careful donor selection and antibody monitoring are crucial to minimize sensitization risks, especially in bone marrow transplant patients.
Area of Science:
- Hematology
- Immunology
- Transfusion Medicine
Context:
- Platelet transfusions are critical for managing bleeding disorders and preventing hemorrhages.
- Prophylactic transfusions are preferred but carry risks of sensitization.
- Specific conditions, such as bone marrow transplantation and alloimmunized patients, require tailored transfusion strategies.
Purpose:
- To outline the indications and conditions for platelet (thrombocyte) substitution.
- To detail strategies for minimizing sensitization risks during transfusions.
- To emphasize the importance of HLA matching and antibody screening in specific patient populations.
Summary:
- Platelet transfusions are indicated for bleeding disorders and prophylactically, with preference for the latter to prevent life-limiting hemorrhages.
- Prophylactic transfusions require careful consideration of sensitization risks, necessitating specific donor selection (e.g., HLA-A/B match) and monitoring.
- Bone marrow transplant recipients and alloimmunized patients have stringent transfusion requirements, including negative cross-tests and HLA compatibility.
Impact:
- Optimized patient management through appropriate platelet transfusion strategies.
- Reduced risk of alloimmunization and transfusion complications.
- Enhanced therapeutic possibilities, including bone marrow transplantation.
