1:1 Blood Resuscitation

We are moving to 1:1:1 transfusion for the bad bleeders and firmly believe it reduces the amount of fVIIa we need to give for those circumstances were we just get too far behind in the transfusion of factors. But I don't really know what endpoints should initiate a 1:1:1 policy, as opposed to just giving 3 or 4 red cells, are seeing what happens (refractory hypotension?, lactate?). Unless we figure out something sensible it will be our next area of irrational exuberance!
Has anyone come up what triggers a change the release policy to 1:1:1?
Cheers

An old addage says that if you aim at nothing - you're sure to hit it.
With the 1:1:1 philosophy if we aim to get the FFP & PLT in to the bleeding patient as soon as possible we may just prevent the complications of the coagulopathy than if we tried to play catch-up later after the massive red-cell only transfusion.
My thought therefore is that by getting the blood bank "on the go" to get the products will end up with something of the comprimise you advocate: somewhere between 1:1 and 1:3 or 4. Some is still better than none.
Also there is more evidence out there for this than just the trials you mention!

Because one swallow doesn't make a spring, and one retrospective military
study shouldn't change global practice.
Most of the evidence of effect lies in those patients that are significantly
under-treated - those that receive no plasma or ratios below 1:4. There is
less effect in lowering the ratio below 1:4. Some studies show benefit,
some no effect, some worse outcome (see paper from Denver at last year's
AAST).
There are huge potential for bias and confounding factors in these
retrospective studies. Gonzalez has shown that patients who are really
bleeding are more likely to fall below the desired transfusion algorithm
(whichever is being used). Those patients who are sickest are more likely
to get lower ratios, as teams struggle to keep up with the haemorrhage and
plasma is delivered slower than red cells.
Those of you who anecdotally believe that less transfusions are used are not
supported by the data, which suggest that an equal amount of products are
used in each group within the first 24 hours. Whatever the mechanism, it's
not clear that the actual number of blood products administered is different
between groups.
The evidence for platelets is even shakier (read non-existent). Especially
if you believe in plasma, because the volume of plasma that the platelets
are stored in could potentially completely explain the platelet effect.
There are significant implications for providing 1:1 plasma instead of 1:3 -
more use of AB plasma, increased risks, increased work for transfusion
staff, increased likelihood of error, and inability to keep up (Par
Johansson, a world-class transfusionist in Copenhagen has been running 1:1
for years and has modelled resource provision. He is clear that provision
of 1:1 ratios during multiple casualty events is almost impossible).
Now I'm not saying that 1:1 is not the right thing to do. It may be, but
we have a suggestion of effect and that is all at present. Read the
Cochrane review on plasma therapy - for any indication. There's so little
evidence out there it behoves us to investigate this more thoroughly before
we expose our patients to 3-4 times the dose of a product we have little
knowledge of.
Sadly I'm speaking 'For' 1:1 in Vegas - which is much easier and more boring
:-)

So there is controversy over 1:1. How do we answer the question? Is a randomized trial justified or is it promising enough to just do it? On the one hand, we spent over 40 years using the intellectually attractive "balanced salt solution" lactated ringers without examining its impact. And blood transfusion therapy during the same interval may have been dictated by the technology that allowed fractionated blood banking - we abandoned whole blood. On the other hand, the results of 1:1 appear extremely promising. Pre-treatment Informed consent will be out of the question. Soooo, how about it Ken, Karim, Ron, Tim, all you trauma.org-istas.

We need to do research that will be large enough to produce enough
subjects in the various treatment arms that differences in outcome will
be clear.
As long as the research is small enough, or not well enough controlled,
that readers can look at the study and state that it is flawed, we will
be avoiding progress.
In 1989 in the cardiology community the question was which
antiarrhythmic, when given to patients who had had heart attacks, would
save the most lives (and make drug companies the most money).
All of the studies prior to that point had been on a surrogate end point
- which drug did a better job of eliminating PVCs.
It was taken for granted that, since patients with PVCs die more
frequently than those without PVCs, that eliminating PVCs saves lives.
The experts were in agreement on this theory.
The study was large enough to show survival differences and it was
allowed to go long enough to produce statistically significant numbers.
Too many studies are stopped early because the results are "too good to
justify withholding the study treatment from others," or vice versa.
How many of these treatments are found to be as beneficial/harmful in
follow up research?
How much of this is self delusion by the study designers?
The result of the CAST (Cardiac Arrhythmia Suppression Trial) was a
surprise to the cardiology world.
One of the drugs was leading to study participant deaths at 3 to 4 times
the rate of placebo.
The best that could be said about any of the drugs was that it did not
appear to be killing the patients at a greater rate than placebo.
All of these drugs are still used, just not very often.
Cardiologists no longer prescribe drugs to get rid of PVCs to everyone
who has had a heart attack.
Antiarrhythmia therapy has become much more conservative (part of that
is due to implantable defibrillators).
Had this study not been done, how long might it have taken before
someone realized this treatment was harmful.
Almost 20 years later, would this still be the focus of care following a
heart attack?
Diseased hearts have PVCs due to underlying disease.
Giving the patient a rhythm stabilizing drug does not change the disease
process, at least not for the better.
This study should have been an example to researchers everywhere.
In stead, it is viewed as an oddity specific to the cardiology
community.
It is not.
We need research that does an excellent job of controlling for as many
variables as possible.
Too much research contains discussions of why variable A is not worth
controlling for, even though it would have been relatively easy to
control for it.
We need to keep these flawed researchers from continuing to do fatally
flawed research.
How is it that experienced researchers, with doctorates in their fields,
continue to engage in research that should not receive passing marks
from a high school science teacher?
The scientific method is one of the most important tools we have.
Its misuse kills.

Based on the CT, I would definitely done an arteriogram, probably within an

tighten anymore.
Negative angio, successful nonoperative therapy
positive angio, plus proximal coiling, successful nonoperative therapy
This strategy gives virtually no failure. Only requires sufficient stability
to allow CT. Failure of nonoperative therapy should be a sentinel event.

Let me be the first to say that I am going to continue to use 1:1:1 as it was presented in Spinella, Holcomb et al, and start to collect data to prove to Karim that this IS the proper way to go if we want to decrease morbidity and mortality in these audibly bleeding patients! ;-)

OH, THANK YOU, THANK YOU, Sal.
I would have had this kid in the angio suite PDQ (pretty damn quick) for angio/embo based solely on the exact point you raised - "have you ever treated conservatively someone without a CT blush who failed conservative management". I have the same tone that you do, and if I were afraid of any spleen failing conservative management, this would have to be one of those!

If Dr. Mattox was not just being polite when he wrote "YES, I agree.
It will be a great session, and I don't really know who will
will win. It will all be in the delivery," then the research
certainly needs to improve significantly. We have far too much that is
the result of persuasive researchers. In stead, we need persuasive
research, not charismatic people driving patient care decisions with
research that does not address what it claims to address. I am not
stating that there is any particular trauma study that this would
describe, but that if the delivery is the deciding factor, the research
is less than adequate.

Gotcha. On that I do agree.
Take care,

If Dr. Mattox was not just being polite when he wrote "YES, I agree.
It will be a great session, and I don't really know who will
will win. It will all be in the delivery," then the research
certainly needs to improve significantly. We have far too much that is
the result of persuasive researchers. In stead, we need persuasive
research, not charismatic people driving patient care decisions with
research that does not address what it claims to address. I am not
stating that there is any particular trauma study that this would
describe, but that if the delivery is the deciding factor, the research
is less than adequate.

For what it's worth, I've appended the most recent version of our
Massive Transfusion Protocol (finalizing as I type; still technically a
DRAFT). It includes default conditions for dispensing plasma. I'd be
obliged for your collective kindly critiquing...
Also have attached a couple of documents we stole from Baltimore in
consideration of building Factor VII into our process. Interesting
reading.
While we're on the subject, my hospital is struggling with ubiquitous
chronic community anticoagulation (there's warfarin in the drinking
water, and more patients on clopidogrel than multivitamins), which
conspires against our rural elderly (geography is destiny -- especially
when your blood won't clot). If anyone would like to share their
approaches, we're all ears. Just got a new platelet function analyzer,
and we're itchin' to use it!

To all,
Who's doing 1:1 fresh frozen plasma to packed RBCs transfusions and
limiting crystalloid for resuscitation in hemorrhagic shock? If you've
adopted it - why? If not - why? Any and all comments requested.
