Pre-operative predictors of the requirement for blood transfusion following total hip replacement



Download PDF

Abstract

We have reviewed prospective data on 1016 patients who underwent unilateral total hip replacement to establish the pre-operative risk factors associated with peri-operative blood transfusion. Most patients who required transfusion were older and were of lower weight, height, pre-operative haemoglobin level and body mass index than patients who were not transfused.

Multivariate analysis revealed that only the pre-operative haemoglobin level and the patients weight were identified as significant independent factors increasing the need for transfusion (p < 0.001). A haemoglobin level below 12 g/dl was associated with a threefold increase in transfusion requirement.
