Blood transfusions for brain bleeding: Large trial in aneurysmal subarachnoid haemorrhage patients adds to debate about optimal threshold
A large trial published in the New England Journal of Medicine is adding to the debate for patients who have had a kind of brain bleeding called aneurysmal subarachnoid haemorrhage (aSAH). Although the randomised controlled trial found no major difference in clinical outcomes between a restrictive compared to a liberal transfusion strategy in critically ill patients following an aSAH, the authors emphasise the potential value of integrating these results with other research to provide a deeper understanding.
The multicentre trial was run by researchers at the Ottawa Hospital and the University of Ottawa, Canada. The Australian arm of the trial was led by Dr. Anthony Delaney, associate professor and senior intensive care specialist at the Royal North Shore Hospital and professorial fellow at The George Institute for Global Health.
