Complications are quite common in surgery to correct spinal deformities due to the long duration under anesthesia and massive blood loss. The aim of this study was to evaluate and compare the effectiveness of Aprotinin in spinal deformity surgery.

Fifty-nine patients who underwent spinal deformity surgery were analyzed. Thirty-two patients were administered Aprotinin, and 27 control patients were not. The Pre- and Post-operative hemoglobin and hematocrit, blood loss, transfusion requirements, operative time, postoperative blood loss through suction drains and duration of suction drains were measured in both groups.

There were no differences in age, gender, height, weight, hemodynamic indices, postoperative blood loss through the suction drains and the duration of the suction drains between the two groups. Intraoperative blood loss, transfusion and operative time were 1,345±425 cc, 1,008±721 cc, and 247 minutes in the Aprotinin (+) group and 2,070±1,276 cc, 2,552±2,791 cc, and 279 minutes in the Aprotinin (-) group, respectively. The postoperative hemoglobin and hematocrit levels were also significantly different (12.9±1 cc and 38.3±3.1% in the Aprotinin (+) group, and 11.9±1.8 cc and 35±5.5% in the Aprotinin (-) group, respectively).

There was significantly less intraoperative blood loss, transfusion and surgery time in the group administered Aprotinin. Therefore, Aprotinin can be used in spinal deformity surgery that has a high risk of massive blood loss.
