Abstract
A program of autologous blood transfusion in 101 patients who underwent spinal surgery was analyzed. Autologous transfusion was achieved by intraoperative blood salvage using a cell saver adn with predeposited blood. The techniques of predeposition of blood included. freezing the blood and using a storage solution. Forty-eight patients had scoliosis and received mainly cryopreserved autologous blood and 53 patients had other spinal diseases. Furgery was performed using only autologous blood transfusion in more than 90% of all patients cases. The program was well tolerated by the patiens and easily managed by the blood canter staff. There were no severe complications associated with this program. The use of instrumentation and extensive spinal fusion were found to be factors associated with inceased intraoparative blood loss. This finding suggests that instrumentation surgery and extensive spinal fusin are indications for autologous blood transfusion. Cryopreserved autologous blood transfusion in an affective method for storing a sufficient volume of blood for scoliosis surgery without affecting the patients' preoperative hemodynamic status.
