The aim of our study was to determine the efficacy and cost-effectiveness of intraoperative autotransfusion that uses the cell saver system (CSS) in patients undergoing posterior instrumentation and fusion of thoracic and lumbar vertebral fractures.


We divided 121 patients who were to undergo posterior instrumentation and fusion due to thoracic and lumbar vertebral fractures into two groups: 59 patients (23 males and 36 females) were in the cell saver group, and 62 patients (22 males and 40 females) were in the control group. Hemoglobin, hematocrit, and red blood cell (RBC) values were recorded for all patients preoperatively, on the postoperative first, second, and third days, and on the hospital discharge day. Transfusion rates and numbers of allogeneic erythrocyte transfusions, as well as the costs of transfused total auto- and allogeneic transfusions were compared.


The numbers of erythrocyte suspensions transfused perioperatively were 0.2±0.6 units in the cell saver group and 0.7±1.4 units in the control group (p=0.01). Statistically significant differences were noted between the two groups on the postoperative first, second, and third days in terms of hemoglobin, hematocrit, and RBC values. These differences had disappeared by the hospital discharge day. The average cost of perioperative blood transfusions was $431±27.4 in the cell saver group and $34.5±66.25 in the control group (p<0.001).


The use of the CSS was not cost-effective, but it was particularly successful at reducing the rate and the number of units of postoperative allogenic blood transfusions.
