Abstract

INTRODUCTION: Revision hip surgery is well documented to have a high association with substantial blood loss and the associated need for a blood transfusion. This exposes the patient to increased risk of transfusion reaction and blood borne infection. There are many strategies to minimize allogeneic transfusion rates in revision surgery such as pre-operative autologous donation, peri-operative tranexamic acid, thrombin sealants, normovolaemic haemodilution, intra-operative blood salvage and the use of post-operative autologous drains. PATIENTS AND METHODS: We prospectively looked at 177 consecutive cases performed at one centre by a single surgical and anaesthetic team to identify which patient and operative factors were most significant in minimizing the requirement for an allogeneic blood transfusion. RESULTS: Our results identified the duration of surgery as being the only significant variable affecting the level of blood loss. We noted a 3% increase in the probability of massive blood loss (> 2000 mls) for every minute of increased surgical time in our series. CONCLUSIONS: We conclude that measures to minimize the duration of surgery would be beneficial in reducing blood loss and the risks of requiring blood transfusions in revision hip surgery.
