Hi MJWL

Over in Germany they have published some work on washing donor blood through the cell salvage machine in their ED Resus. Main aim was to remove K+ and other contaminants, including haemolysis, but there is actually more haemolysis caused by the cell salvage process than that in a donor unit!
In critical scenerios I would be concerned about adding in additional delay, in obtaining a maching, priming it, spiking unit, sampling....etc, but their reports stated no impact on provision. It's not something that the UK is undertaking.
