Suspended Animation for Dogs

SCIENTISTS have created eerie zombie dogs, reanimating the canines after several hours of clinical death in attempts to develop suspended animation for humans.

US scientists have succeeded in reviving the dogs after three hours of clinical death, paving the way for trials on humans within years.
Pittsburgh's Safar Centre for Resuscitation Research has developed a technique in which subject's veins are drained of blood and filled with an ice-cold salt solution.

The animals are considered scientifically dead, as they stop breathing and have no heartbeat or brain activity.

But three hours later, their blood is replaced and the zombie dogs are brought back to life with an electric shock.

Plans to test the technique on humans should be realised within a year, according to the Safar Centre.

However rather than sending people to sleep for years, then bringing them back to life to benefit from medical advances, the boffins would be happy to keep people in this state for just a few hours,

But even this should be enough to save lives such as battlefield casualties and victims of stabbings or gunshot wounds, who have suffered huge blood loss.

During the procedure blood is replaced with saline solution at a few degrees above zero. The dogs' body temperature drops to only 7C, compared with the usual 37C, inducing a state of hypothermia before death.

Although the animals are clinically dead, their tissues and organs are perfectly preserved.

Damaged blood vessels and tissues can then be repaired via surgery. The dogs are brought back to life by returning the blood to their bodies,giving them 100 per cent oxygen and applying electric shocks to restart their hearts.

Tests show they are perfectly normal, with no brain damage.

"The results are stunning. I think in 10 years we will be able to prevent death in a certain segment of those using this technology," said one US battlefield doctor.

I'm particularly interested in that they want to apply it to more every-day uses by keeping people suspended for a few hours while they get to the hospital. I always thought this could be only used for space travel.

Thats really interesting, I wouldn't have thought something like that would even be possible.
 
They also didn't say anything about the condition of the dogs before they were "clinically dead" either, unless I just missed it. They may have been perfectly healthy, then purposfully temporarily killed. I want to know if they had any pre-existing health problems.
 
Huh, I wonder if they're dealing with ice crystals possibly forming at all? That's the main problem (aside from fracturing) with simply freezing people and thawing them out later. You need to go directly from a liquid to a glass state. This, of course, isn't the same thing... More like preserving meat in a freezer. I doubt you could use this for long term hibernation. Even cooled, the cells will start to deteriorate after an extended period of time with no oxygen. I wonder if any cryoprotectants are used and how they flush all of the water out of the veins and capillaries once they need to put the blood back in. - Colt
 
I guess they wouldn't need to get all of the salt solution out. It would be just like giving IV fluids if they didn't... kind of rehydrating the dog.
 
Sweet! It's possible to revive a dead creature. Now I can have myself frozen before death and revived when cure to whatever condition I have is discovered. I will be able to live forever! :D
 
Until someone puts you into a microwave and hits the "reheat" button, thinking the frozen rat in the freezer was a regional speciality.
 
I agree... A lot of clinical procedures are first done on dogs though. The first heart transplants (partial and full) were.

I wouldn't be so sure, "the nerd syndrome" is not so easily cured. :wink:

Back on topic:
It's surprising how cruel humans can be to animals.

That is exactly what I was thinking.

What I wonder is exactly how they get all the solution out of the dog to replace it with blood? My thinking is the solution is somewhat harmless so if even only 80% gets replaced with blood the rest will be removed by way of the liver and various excretory pathways. Though I would bet the dog would wake up feeling like hell if that was true.

New York Post[/url]]For a long time, the test subjects couldn't be brought back to life after more than two hours. But recently, the researchers added glucose and more oxygen to the blood and have pushed the maximum time the dogs can be dead to three hours.

"We've tried to get it to four hours, but we just haven't been able to do it," Kochanek told The Post.

The lucky ones turn out to be perfectly normal with no brain damage — although other dogs are stricken with serious physical or behavioral problems.

"We do not in any way say that every outcome is normal," Kochanek said.

And they aren't at absolute zero, so deterioration would be inevitable if they somehow managed to extend the time beyond a few hours.

And they're going to try and do research on humans? I'd rather not become part of that research if it comes down to it ^_^.
 
Maybe they should try it on some chimps who know sign language, maybe they could find out how it feels like...
Sounds promising but testing on humans within a year seems kind of rash.
