Background:
@EN During total hip arthroplasty, replacement of substantial amount of blood loss is necessary. The adverse effects of homologous blood transfusion have been documented consequently and the intraoperative autotransfusion has attracted
considerable
interest. The authors have attempted to reduce the amount of the homologous blood transufusion by inducing hypotension and autotransfusion.
@ES Methods:
@EN Twenty patients who underwent revision total hip arthroplasty were divided into two groups. Group I received homologous blood perioperatively. Group II was transfused with predonated autologous blood and intraoperative salvage technique with
Cell
Saver apparatus, were used along with sodium nitroprusside for hypotensive anesthesia to decrease intraoperative bleeding. We observed the amount of blood loss and transfused blood, and hematologic laboratory data, and complications.
@ES Results:
@EN The mean requirement for transfusion was 3083ml in group I and 1289 ml in group II. In the level of the hematocrit, there was a significant smaller hematocrit drop (8%) over the first two postoperative days in group II. There were no
complications
such as disseminated intravascular coagulopathy, severe thrombocytopenia, microemboli, and nephrotoxicity.
@ES Conclusions:
@EN The autologous transfusion and induced hypotension in the total hip arthroplasty is though to be an effective method to reduce the amout of homologous blood transfusion. (Korean J Anesthesiol 1996; 30: 692~697)
