[Does preoperative erythroapheresis avoid homologous transfusion?]
1Centre d'Hémobiologie-Transfusion, Groupe Hospitalier Pitié-Salpêtrière, Paris.
The risk of transfusion-related viral infections promotes techniques intended to reduce such a risk. Preoperative erythroapheresis is an autologous blood collection technique which minimizes the inconvenience of repeated predeposit autologous donations. Erythroapheresis has been performed in 451 patients, 24 to 72 hours before surgery using a discontinuous flow cell separator (PCS+Haemonetics). The mean collected red cells volume was 485 ml (250-900) and was replaced by hydroxy-ethyl-starch (ELOHES). Homologous blood transfusion was avoided in 431 patients (95,6%). This technique is indicated for surgery with an expected blood loss between 1000 and 1500 ml or when the patient cannot be included in a preoperative blood donation programme. Preoperative erythrocytapheresis is a simple and well tolerated procedure. To have recourse to apheresis techniques allows to increase the number of autologous transfused patients.
