Abstract
Introduction
The correction of paediatric scoliosis is a surgical procedure in which substantial bleeding occurs, and which historically has been associated with high levels of blood transfusion. Transfusions are associated with risks of infection, allergic reactions, volume overload and immunosuppression.
The purpose of our study was to evaluate the efficacy of a care pathway implemented at St Thomas' hospital over ten years with a focus on minimising the need for blood transfusions. A Spinal Surgery Care Pathway was developed including: nurse-led clinics facilitating pre-operative haemoglobin optimisation; intra operative cell-salvage, the use of tranexamic acid, and a transfusion criteria awareness programme.
Methods
We reviewed the records of all patients 18 years of age or younger undergoing spinal corrective surgery between 2000 and 2010. Collating data from the surgical records and haematology laboratory, we identified the proportion of patients requiring transfusion and the respective volume of blood or blood products transfused.
Results
534 spinal procedures were undertaken on patients over the decade of interest. Over this time, the proportion of patients requiring transfusion reduced from 83.3% in 2000, to 6.4% in 2010 (p < 0.001); a consistent year on year reduction was witnessed between 2005 and 2010. In those requiring transfusion, the volume of packed red cells transfused fell from a mean of 7.7 units in 2000, to 1.5 units in 2010 (p < 0.001). These results were despite an increase in posterior fusions, associated with higher bleeding, from 50.0% to 79.4% over the same time period.
Conclusion
Over ten years, we have demonstrated that the implementation of a multifaceted, multidisciplinary pathway together with challenging cultural attitudes to blood transfusion, can dramatically and sustainably reduce the need for blood transfusion and the risks associated therewith. These data lends weight to the adoption of such a care pathway in paediatric scoliosis surgery.
