Would this work to stop hemorrhagic bleeding? We'll never know because our stroke associations will never follow up with research to test this out.

UBC researchers have created the first self-propelled particles
capable of delivering coagulants against the flow of blood to treat
severe bleeding, a potentially huge advancement in trauma care.
“Bleeding is the number one killer of young people, and maternal
death from postpartum hemorrhage can be as high as one in 50 births in
low resource settings so these are extreme problems,” explains Christian
Kastrup, an assistant professor in the Department of Biochemistry and
Molecular Biology and the Michael Smith Laboratories at the University
of British Columbia.
Traditional methods of halting severe bleeding are not very effective
when the blood loss originates inside the body like the uterus, sinus
or abdomen.
“People have developed hundreds of agents that can clot blood but the
issue is that it’s hard to push these therapies against severe blood
flow, especially far enough upstream to reach the leaking vessels. Here,
for the first time, we’ve come up with an agent that can do that,”
Kastrup said.
Kastrup teamed up with a group of researchers, biochemical engineers
and emergency physicians to develop simple, gas-generating calcium
carbonate micro-particles that can be applied in powder form to stop
critical bleeding.
The particles work by releasing carbon dioxide gas, like antacid tablets, to propel them toward the source of bleeding.
The carbonate forms porous micro particles that can bind with a
clotting agent known as tranexamic acid, and transport it through wounds
and deep into the damaged tissue.
After studying and modeling the movement of the particles in vitro,
the researchers confirmed their results using two animal models. Even in
a scenario that mimicked a catastrophic event like a gunshot wound to a
femoral artery, the particles proved highly effective in stopping the
bleeding.
While much more rigorous testing and development is needed to bring
the agent to market, the particles could have a wide range of uses, from
sinus operations to treating combat wounds.
“The area we’re really focusing on is postpartum hemorrhage: in the
uterus, after childbirth where you can’t see the damaged vessels but you
can put the powder into that area and the particles can propel and find
those damaged vessels,” said Kastrup.
This study was published in today in Science Advances. The research was
initially funded by the University of British Columbia and through a
“Rising Stars” grant from Grand Challenges Canada. Collaborators
included James Baylis, a Ph.D candidate in the Department of Biomedical
Engineering at the University of British Columbia, Nathan White, a
trauma specialist at the University of Washington in Seattle, Thomas
Burke, the Chief of the Division of Global Health and Human Rights at
Massachusetts General Hospital, Lindsay Machan from the Department of
Radiology and James Piret from the Department of Chemical and Biological
Engineering at the University of British Columbia.
Use the labels in the right column to find what you want. Or you can go thru them one by one, there are only 28,987 posts. Searching is done in the search box in upper left corner. I blog on anything to do with stroke.DO NOT DO ANYTHING SUGGESTED HERE AS I AM NOT MEDICALLY TRAINED, YOUR DOCTOR IS, LISTEN TO THEM. BUT I BET THEY DON'T KNOW HOW TO GET YOU 100% RECOVERED. I DON'T EITHER, BUT HAVE PLENTY OF QUESTIONS FOR YOUR DOCTOR TO ANSWER.
Changing stroke rehab and research worldwide now.Time is Brain! trillions and trillions of neurons that DIE each day because there are NO effective hyperacute therapies besides tPA(only 12% effective). I have 523 posts on hyperacute therapy, enough for researchers to spend decades proving them out. These are my personal ideas and blog on stroke rehabilitation and stroke research. Do not attempt any of these without checking with your medical provider. Unless you join me in agitating, when you need these therapies they won't be there.
What this blog is for:
My blog is not to help survivors recover, it is to have the 10 million yearly stroke survivors light fires underneath their doctors, stroke hospitals and stroke researchers to get stroke solved. 100% recovery. The stroke medical world is completely failing at that goal, they don't even have it as a goal. Shortly after getting out of the hospital and getting NO information on the process or protocols of stroke rehabilitation and recovery I started searching on the internet and found that no other survivor received useful information. This is an attempt to cover all stroke rehabilitation information that should be readily available to survivors so they can talk with informed knowledge to their medical staff. It lays out what needs to be done to get stroke survivors closer to 100% recovery. It's quite disgusting that this information is not available from every stroke association and doctors group.
