Oxidized Regenerated Cellulose Can Reduce Hidden Blood Loss after Total Hip Arthroplasty: A Retrospective Study.

: There is a large amount of hidden blood loss (HBL) after total hip arthroplasty (THA), but the effective and safe methods to reduce HBL are still controversial. : Sixty-nine consecutive patients who underwent THA in our hospital from January 2015 to December 2015 were analyzed retrospectively. The patients were divided into two groups, Group A (THA without oxidized regenerated cellulose) and Group B (THA with oxidized regenerated cellulose). Demographics, perioperative laboratory values, intraoperative data, blood loss, transfusion rate, transfusion reactions, and surgical complications were collected and analyzed. : A total of 37 (54%) patients used oxidized regenerated cellulose (ORC) in operation. The total blood loss (TBL), postoperative blood loss (PBL), hemoglobin (Hb) loss, and hidden blood loss (HBL) in group B were significantly lower than in group A. : The use of ORC to fill the bone surface and soft tissue gap before incision closure can effectively reduce HBL and may be a potential treatment for blood prevention after THA.
