Abstract:

Total knee arthroplasty (TKA) and total hip arthroplasty (THA) are the most two common types of artificial joint arthroplasty. Although minimally invasive surgery and tourniquet have alleviated postoperative bleeding to a certain extent, most patients with TKA and THA have unexplained anemia symptoms and a large reduction in hemoglobin, but there is little observable blood loss, which may be related to hidden blood loss. The postoperative complications, wound healing and functional rehabilitation of patients are affected by hidden blood loss, which has gradually become a clinical problem that can not be ignored by orthopaedics doctors. Hidden blood loss is affected by many factors in the perioperative period, and the pathophysiological mechanisms are also diverse. Moreover, because of its concealment, the symptoms have already occurred and developed for a long time, which is easy to delay the best treatment opportunity and affect the postoperative curative effect. This paper reviews the possible mechanisms and influencing factors of hidden blood loss, so as to provide guiding significance for actively preventing hidden blood loss after TKA and THA.
