Improving Transfusion Practice in Transfusion Dependent Thalassaemia Patients

The aim of this study was to improve current transfusion practice in transfusiondependent thalassaemia patients by determining whether safe transition from triplewashed red cells (TWRC) to leucodepleted red cells (LDRC), increasing transfusion rates, reducing the use of frusemide and creating uniform practice across patients is possible. In patients receiving regular transfusions (50), triple-washed red blood cells were changed to LDRC, transfusion rates were increased to 5 mL/kg/h (in line with the Cooley’s Foundation guidelines) to a maximum of 300 mL/h and frusemide was ceased. Medical review occurred at completion of the transfusion. Of the 20 patients on TWRC, 18 were transitioned to leucodepleted red cells (90%). Recurrent allergic reactions in 2 patients required re-institution of TWRC. 7 of the 8 patients on regular frusemide ceased this practice with no documented transfusion-related fluid overload. One patient refused. Of the eligible 50 patients, 20 patients (40%) were increased to the maximum transfusion rate of 300 mLs/h; 6 (12%) increased rate but refused to go to the maximum; 9 (18%) refused a change in practice and 15 (30%) were already at the maximum rate. There was only one documented transfusion reaction (palpitations) however this patient was able to tolerate a higher transfusion rate on subsequent transfusions. Thalassemia patients on TWRC were safely transitioned to LDRC. Transfusion rates were safely increased, with a calculated reduction in day-stay bed time of 17.45 h per month. This confirms a guideline of 5 mL/kg/h for transfusion-dependant thalassaemia patients with preserved cardiac function is well tolerated and may be translated to other centres worldwide.
