Do I really think the grade 1 SAH with a whisp of blood and low risk of DCI needs a Hgb of 9? No.
But for pt in clear vasospasm (aSAH but also TBI) or other perfusion disturbing physiology I think I will keep 9 as my threshold.

Interested in how others are interpreting these results. Again, huge congrats to the authors. and a special shout out to Dr. Ofer Sadan who led the SAHARA effort at

I think there is enough data to suggest that aiming for 9g/dL PARTICULARLY (maybe exclusively) in pts at ⬆️ risk for decreases in cerebral perfusion due to ongoing physiologic changes like vasospasm makes sense given the control population in this trial & the results of TRAIN

The way I have put this together, is that I will be more aggressive (than the standard 7 or what we have allowed as 8g/dL) in transfusions for the patients at highest risk for secondary neurologic injury.

It seems to me a take away is that 10g/dL is too high to offer benefit, but the lowest acceptable number I think is still up for debate, and TRAIN would suggest 9g/dL might be a more reasonable target.
Indeed, the restrictive group in SAHARA was on average > that threshold

In other neurocritically ill pts including SAH (the recently published TRAIN trial), we did reduce unfavorable outcomes when we set the "liberal" threshold of <9g/dl and restrict all the way down to <7g/dl. This looked at 6 month outcome.

This trial was very well done and is pragmatic and generalizable.
The threshold of 10 doesn't seem to improve neurologic outcomes.
However, I don't look at this trial and think that we conclude that maintaining a daily hgb of 8g/dl is proven ok.

Between these two groups, there was no significant difference in mRS at 12 months and the risk of having a poor outcome.

Note also that once the liberal group got transfused they also mostly stay well above even the liberal threshold.
So intervention was transfusion for a low threshold of 8g/dl ... but we're I think ultimately comparing outcomes for avg daily hgb of ~11g/dL to ~9.5 g/dL

However, while the two group are clearly different, its important to note... the restrict group was on avg above 9 g/dl.
Said differently the controls were anemic, but did not linger 8g/dL threshold... so, the intervention, if needed, got them well away from the "danger" level
