SCIENCE can do anything: 1940’s experiment on dead dog’s head.

Once Martin lurther king. Jr said ‘Our scientific power has outrun our spiritual power. We have guided missiles and misguided men.’ , but in 1940″ during the world war Russian scientists was in different world of experiments. In 1940, Russian scientists released a video of severed dog heads that were kept alive for several hours, wiggling their ears in response to sounds and even licking their mouths. The scientists claimed they could keep the animals alive by an artificial blood circulation system.Experiments in the Revival of Organismsо is a 1940 motion picture which documents Soviet research into the resuscitation of clinically dead organisms. It is available from the Prelinger Archives, and it is in the public domain. The operations are credited to Doctor Sergei Brukhonenko and Boris Levinskovsky, who were demonstrating a special heart-lung apparatus called the autojektor (or autojector), also referred to as the heart-lung machine, to the Second Congress of Russian Pathologists in Moscow.[2] It was filmed at the Institute of Experimental Physiology and Therapy, which is also in Moscow.[3] The heart-lung machine was designed and constructed by Brukhonenko, whose work in the film is said to have led to the first operations on heart valves.The autojektor device demonstrated in the film is similar to modern ECMO machines, as well as the systems commonly used for renal dialysis in modern nephrology.

Sergei Brukhonenko’s ‘Device for Artificial Circulation’ meant that blood could still pump around the body, or head, while the heart was removed.

It consisted of two parts – an oxgenator to saturate the blood with oxygen and removed excess carbon dioxide and a pump.

The pump drew used blood from the hear and deposited it in a glass chamber. It was warmed, oxygenated and then pumped back into the animal.

Using the system of tubes and pumps the head is sustained with oxygen and blood.

The head is subject to stimuli to prove it is in control of its faculties while on the machine.

The pump was not hermetically sealed and eventually the blood would coagulate. However, Brukhonenko was able to keep a dog’s head alive for one hundred minutes.

The device was never used in a clinical open heart surgery and a newer version created in the mid-1950s by John Gibbon overshadowed the work of Brukhonenko.

Modern devices are based on the same principles but are now much more complex and also control the chemical composition and temperature of the blood flowing into the body.
