The role of red cell transfusion in the management of iron-deficiency anaemia is controversial. This audit was undertaken to monitor the overall transfusion practices of patients admitted to a 600-bed acute tertiary hospital with confirmed severe iron deficiency. ⋯ Red cell transfusions are commonly administered to elderly patients with severe iron-deficiency anaemia. They may be necessary to alleviate severe morbidity until the time at which iron therapy becomes clinically effective. However, greater emphasis should be given to restrictive transfusion strategies and dosing. Transfusion of single red cell units followed by clinical assessment will determine the need for subsequent units and ensure that this valuable resource is appropriately used.

Transfusion based on the Thrombelastograph (TEG) results reduces transfusion requirements in cardiac surgery and in liver transplantation. Taking the pivotal role of thrombin generation in the coagulation process into consideration, the clinical utility of the TEG may, in part, depend on its reflection of the dynamics of thrombin generation. ⋯ The kinetics of thrombin generation, as evaluated by CAT, correlates with the thrombus generation, as evaluated by thrombelastography and this may in part explain the clinical utility of the TEG in identifying clinically relevant coagulopathies, secondary to impaired thrombin generation.
