Use of re-transfusion versus vacuum drains in primary total hip replacement

Whilst the use of re-transfusion drains in primary knee arthroplasty has gained acceptance in reducing the requirement for donor blood products postoperatively, their use in total hip arthroplasty remains uncertain. Using two groups of 32 patients, a comparison was made between re-transfusion drains and vacuum drains in primary total hip arthroplasty in one centre and the requirement for postoperative donor blood. No statistically significant difference was found between the groups in terms of blood loss (p=0.51) or requirements for postoperative blood transfusion (p=0.12). The use of re-transfusion drains in primary total hip arthroplasty did not alter the rate of postoperative blood transfusion.
