THE EFFECT OF CELL SAVERS ON THE TRANSFUSION RATE AND POSTOPERATIVE HAEMOGLOBIN IN PATIENTS UNDERGOING A PERIACETABULAR OSTEOTOMY FOR HIP DYSPLASIA.



Abstract

Introduction: We present the results of a prospective study of the blood transfusion requirements in patients undergoing a Bernese periacetabular osteotomy (PAO) with the use of an intra-operative cell-saver and without pre-donated blood. These data were compared with an earlier audit of patients who underwent this procedure without use of a cell saver.

Material and Methods: A cohort of 50 patients (56 hips) underwent a PAO for hip dysplasia between December 2006 and November 2008 performed by the senior author. The average age was 29 years (17–51) and there were 38 females and 12 males. The average weight was 69.96 kg (46–110) and the mean duration of operation was 136 minutes (100–240). A cell saver (Fresenius-Hemocare, Germany) was used intra-operatively for this cohort. Pre-operative Hb, post-operative Hb taken the day after surgery and any units transfused were documented. A post-operative transfusion policy was adopted where a haemoglobin (Hb) concentration of < 7.5 g/dl was an indication for transfusion or where a patient was sufficiently symptomatic

Results: The mean pre-operative Hb was 13.60 g/dl (10.8–15.9) and the mean post-operative Hb was 9.91 g/dl (6.4–11.8). Overall 4 patients received post-operative allogenic blood transfusion; 3 patients receiving one unit and one patient receiving 2 units. No patients received intra-operative allogenic blood.

Conclusion: Compared to our previous audit, the use of the cell saver resulted in an improvement in the mean post-operative Hb, (9.2 g/dl compared to 8.0 g/dl). The transfusion rate was also reduced (7.27% compared to 10.8%)..
