術後回収式自己血輸血装置 (CBC II) の使用経験

抄録

The aim of this study is to confirm the safety and usefulness of postoperative autologous blood retrieval and transfusion using the Stryker CBC II ConstaVac Blood Conservation System (CBC II), and to avoid homologous blood transfusion when heavy bleeding is indicated during and after hip joint surgery.
CBC II was used in 20 patients who were treated with Spherical Acetabular Osteotomy (SAO) for osteoarthritis of the hip joint. The average amount of postoperative bleeding was 648.3ml, and reinfused blood was 431.3ml. The mean rate of reinfusion (the amount of reinfused blood/the amount of postoperative bleeding) was 66.6%. The average value of hemoglobin in reinfused blood was 8.9g/dl. There were no cultures showing gram negative and gram positive bacteria in reinfused blood. In all cases, there were no complications of CBC II and homologous blood transfusions were avoided.
It is concluded that CBC II is safe and useful for avoiding homologous blood transfusions when heavy bleeding is indicated during and after hip joint surgery.
