Re: A gel that can stop severe bleeding instantly
#2Sounds cool, but I wonder what would happen with bacteria that are trapped underneath the rapidly solidifying gel.
Usually, the flow of blood tends to wash pathogens out of the wound, reducing the chance of nasty infections. Positive blood pressure can therefore be considered a natural defense mechanism. But if you stopped the bleeding too quickly, wouldn't it trap pathogens inside the body before the blood has had a chance to wash them out? Or does the extra-rapid clotting actually trap pathogens within the solid matrix, preventing them from spreading further into the body?

It's a temporary stop-gap. I'm assuming the strategy would be that when the injured gets brought in for treatment, then you re-open the wound, cleanse the area, and give the body appropriate anti-biotics to fight off any infections.
You've gotta pick the lesser of two evils - somebody that bleeds out, or somebody that is alive and able to fight off an infection.

I would imagine its a trade off, infections can be more readily treated, however bleeding out only takes a few moments.

Seems like you could mix in a triple antibiotic?

The article mentions that you can freely mix antibiotics into the gel, so hopefully such a thing would prevent (or at least resist) infection in the wound.

#7Could you not just use Superglue for a temporary fix before treatment?

No doctor talking: I think it all depends on the situation. If you are bleeding heavily and the only way to stopp it quickly enough would be to use the gel then use it and treat the bacteria later with antibiotics or something...

I am not a doctor, but from what I've read, treating an infection is usually considered much less of a priority by emergency responders than stopping severe bleeding.
You can bleed to death in a few minutes. Few if any infections are going to be that fast-acting. So stopping severe bleeding will hopefully buy you some time to get to the ER, where they'll pump you full of antibiotics if they have to.

#10I wonder how this differs from the existing products celox[1] and quikclot[2], which AFAIK are coagulants?

edit: from a quick look over all three (I'm no expert), it seems like this new one might be faster acting.
