AIM To investigate whether autologous blood transfusion(ABT) drains and intra-operative cell salvage reduced donor blood transfusion requirements during scoliosis *** Retrospective data collection on transfusion requirements of patients undergoing scoliosis surgery is between January 2006 and March 2010. There were three distinct phases of transfusion practice over this time: Group A received "traditional treatment" with allogeneic red cell transfusion(ARCT) in response to an intra- or postoperative anaemia(Hb < 8 g/d L or a symptomatic anaemia); Group B received intra-operative cell salvage in addition to "traditional treatment". In group C,ABT wound drains were used together with both intra-operative cell salvage and "traditional treatment".RESULTS Data from 97 procedures on 77 patients,there was no difference in mean preoperative haemoglobin levels between the groups(A: 13.1 g/d L; B: 13.49 g/d L; C: 13.66 g/d L). Allogeneic red cell transfusion was required for 22 of the 37 procedures(59%) in group A,17 of 30(57%) in group B and 16 of 30(53%) in group C. There was an overall 6% reduction in the proportion of patients requiring an ARCT between groups A and C but this was not statistically significant(χ2 = 0.398). Patientsin group C received fewer units(mean 2.19) than group B(mean 2.94)(P = 0.984) and significantly fewer than those in group A(mean 3.82)(P = 0.0322). Mean length of inpatient stay was lower in group C(8.65 d) than in groups B(12.83) or A(12.62).CONCLUSION When used alongside measures to minimise blood loss during surgery,ABT drains and intra-operative cell salvage leads to a reduced need for donor blood transfusion in patients undergoing scoliosis surgery.
