Efficiency of leukocyte depletion filters and micro-aggregate filters following intra-operative cell salvage during cesarean delivery

Allogenic and autologous blood transfusions have been used for the treatment of severe obstetric hemorrhage associated with placenta accreta, placenta previa, and atonic bleeding. However, allogenic transfusion is associated with the risk of infection and allergic reactions, and there is a limit to the amount of autologous blood that can be collected before delivery. Intra-operative cell salvage (ICS), used in cardiovascular, orthopedic and gynecological surgery involves use of blood from the bleeding site collected through a heparinised tube, separation of cells by hemoconcentration, differential centrifugation in 0.9% saline, and finally washing of cells in 1 –2 L of 0.9% saline.
