While I am not sure how long the Soviets were able to keep the dogs alive for (they say "hours"), there is a very interesting film about reanimation of dogs from decades ago. Warning that the film does show a decapitated dog being artificially kept alive through a bypass device. A much different era. https://m.youtube.com/watch?v=KDqh-r8TQgs https://m.youtube.com/watch?v=KDqh-r8TQgs

I have seen this. I tend to question whether they actually did it, and whether this represents an authentic film. Consider, say, the space race. They have a clear motivation to demonstrate superiority close to this era. I have also gotten the impression that the classic soviet government didn't exactly have a reputation for sterling honesty, and this doesn't seem wildly far afield from something you could achieve with practical effects. I have limited specialist domain knowledge, but the head doesn't really have a power source. Blood can give the brain oxygen, but hours seems a bit far-fetched. They definitely skip a lot of detail here, like where/how they oxygenate the blood without lungs. The head has the brain, which takes a lot of energy to run for its size, and probably doesn't carry out the metabolic processes of energy production, with the blood/brain barrier. So, you have a big power draw, and no engine. Hours of observable or verifiable life seems like a lot for stale blood with no power source and a big power draw. I also don't know the authentic history of the video to verify it didn't come as a complete fabrication of a historical curiosity at a later date. I would like to see credible verification, but it doesn't really add up.

  Thank you for your response. I do have some domain knowledge as it seemed to be a crude form of ECMO (https://en.m.wikipedia.org/wiki/Extracorporeal_membrane_oxygenation https://en.m.wikipedia.org/wiki/Extracorporeal_membrane_oxyg...) , but it made me dig deeper into the history of extracorporeal perfusion. I think you will enjoy the link below which has a lot of information about the video. The scientist in the beginning of the film is the famous physiologist Haldane, which is why I originally believed the video. However your response led me to find out he was a Marxist! Now I was torn and had doubts. Turns out that while the film was propaganda aimed toward Western Scientists, it was real and did work. http://perfusiontheory.com/who-really-invented-the-heartlung-pump-and-ecpr/ http://perfusiontheory.com/who-really-invented-the-heartlung...

    Thanks for the link! It was interesting. I could never really figure out if it was real. Seems pretty advanced for the time. I definitely didn't know about ECMO.

    > However your response led me to find out he was a Marxist! You say that as if you just found out he was a member of ISIS and killed women and children by burning them alive. I can't find anything in Karl Marx' teachings that could cause such a response, even when you disagree with him completely.

      I think there is a misunderstanding about what is surprising, I'd be just as surprised if he was an Ayn Rand card-carrying objectivist (is that what they call themselves?). My surprise was that I didn't think Haldane would have any political bias to cause doubt about the authenticity of the video.
