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

BACKGROUND

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.

METHODS

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.

RESULTS

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.

CONCLUSIONS

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.
