THE USE OF AUTOLOGOUS BLOOD TRANSFUSION DRAINS IN ELECTIVE TOTAL KNEE ARTHOPLASTY

To date, there are no clear guidelines from the National Institute of Clinical Excellence or the British Orthopaedic Association regarding the use of Autologous Blood Transfusion (ABT) drains after elective primary Total Knee Replacement (TKR). There is little evidence to comparing specifically the use of ABT drains versus no drain. The majority of local practice is based on current evidence and personal surgical experience.We aim to assess whether the use of ABT drains effects the haemoglobin level at day 1 post-operation and thus alter the requirement for allogenic blood transfusion. In addition we aim to establish whether ABT drains reduce post-operative infection risk and length of hospital stay.Forty-two patients undergoing elective primary TKR in West London between September 2011 and December 2011 were evaluated pre- and post-operatively. Patient records were scrutinised. The patient population was divided into those who received no drain post-operatively and those with an ABT drain where fluid was...
