The blood saving protocol, which is the product of 15 years of experience, has gradually been improved, until the current form has been achieved, which includes predeposit, acute intentional isovolemic hemodilution, controlled hypotension, intraoperative blood recovery, postoperative monitoring and blood recovery, external compressive elastic dressing. The acceptance of values for hemoglobin which may even be < 8 g/dl during the late postoperative period, as long as this is well-tolerated by patients, has allowed us to drastically reduce the use of homologous transfusions. Over the last 2 years, out of 59 autotransfused patients submitted to revision surgery of the hip, only 9 (equal to 15%) required homologous transfusion. An analysis of the data shows that the use of homologous blood is associated with the presence of ischemic cardiopathy (p < 0.001) and with a predeposit which is less than 4 units of blood (packed red blood cell+fresh frozen plasma) (p = 0.05).
