Research Article: Risk Factors Analysis and Nomogram Model Establishment of Hidden Blood Loss in Overweight and Obese Elderly Patients After Total Hip Arthroplasty
Abstract:
Total hip arthroplasty (THA) is a common treatment for hip joint diseases in elderly patients, such as aseptic necrosis of the femoral head, femoral neck fractures, and other end-stage hip diseases., The mean perioperative blood loss in primary unilateral THA is ml, increasing the probability of postoperative allogeneic transfusion, which may lead to an increase in complications, mortality, and length and cost of hospital stays. However, total blood loss (TBL) after THA is higher than that actually observed, as first described in by Pattison et al and formally defined as hidden blood loss (HBL) in ., Blood infiltration into the tissues, blood accumulation around the joints, and hemolysis contribute to the formation of HBL.–
