In the University Hospital of Granada (Spain), 359 trauma surgical patients underwent intraoperative autotransfusion. Patients from group I (blood loss less than 2000 ml) did not requiere homologous blood transfusion. So the high risk involved in the type of transfusion was avoided. With patients from group II, however, that is, those with a blood loss of more than 2000 ml, we had to fall back on homologous transfusion in addition to retransfusing autologous blood. The main indication for intraoperative autotransfusion is without doubt abdominal and thoracic trauma which lead to high blood loss.

In the University Hospital of Granada (Spain), 359 surgical trauma patients underwent intraoperative autotransfusion. The patients were divided into 2 groups, according to their blood loss: group I (blood loss less than or equal to 2000 ml) and group II (blood loss greater than 2000 ml). Patients from group I did not require homologous blood transfusion. So the high risk involved in this type of transfusion was avoided. Macroscopic haemoglobinuria was only found in those patients where the Solcotrans, Viavae type of autotransfusion system was used; with the Bentley ATS system, no macroscopic haemoglobinuria was registered. With patients from group II, however, that is, those with a blood loss of more than 2000 ml, we had to fall back on homologous transfusion in addition to retransfusing autologous blood. When the transfusion exceeds 4000 ml there is increasing bleeding, which requires treatment with fresh frozen plasma, platelets and/or fibrinogen. The mortality rate of patients in group II was very high but the patients died from the severity of their injuries or from postoperative complications which were not due to autotransfusion in itself with the exception of 3 patients who underwent massive autotransfusion (12,000 to 25,000 ml) and died from acute renal failure. The main indication for intraoperative autotransfusion is without doubt abdominal and thoracic trauma which lead to high blood loss.
