title: Blood loss during primary total hip arthroplasty: use of preoperative measurements to predict the need for transfusion.
abstract: The blood loss resulting from total hip arthroplasty was studied in 53 patients. Calculated blood loss exceeded measured blood loss in all cases. The most significant predictor of postoperative packed-cell volume (PCV) was the preoperative PCV. In a further 37 patients the preoperative PCV was used successfully to predict the postoperative PCV and the need for transfusion.
