Now You Can Come Back From the Dead - Really

Back from deadThe New York Post reported on a wonderful but eerie capability of the human body to come back to life after being dead for even hours at a time. MAUREEN CALLAHAN reports that death can be reversed as long as certain conditions are there.

The implications are as revolutionary as the discovery of fire and electricity, the invention of aviation and manned space flight, the A-bomb and the Internet. “For millennia, we couldn’t do anything when someone stopped breathing,” Dr Parnia says. “Now, we’re almost having to redefine the way we think about death.”

The science is still in its infancy, and successful resuscitation requires two non-negotiables: a treatable underlying cause of death, such as a clogged artery or fluid in the lungs, and a body that has been cooled, either naturally or artificially. It’s the cooling that retards cell death in the body and the brain, protecting against cognitive impairment.

The possibilities are almost inconceivable. In the near future, if you were to die of cardiac arrest before an organ transplant, you may be dead for hours or days while a new organ is found — or grown from your own stem cells — then transplanted before you’re revived. Studies are underway involving a new drug that slows the rate of brain-cell death by 50%, which could double the viability of a corpse. Death may eventually become less a permanent state than a way station.

“Many who died young and prematurely could have been saved,” Parnia says. “I arrived at Stony Brook in 2010, and we barely had any cooling being done in this unit.” Last Monday, a 50-something patient died in the cath lab at Stony Brook; she had a diseased heart and was on the list for a transplant. “We got her back in an hour and a half,” Parnia says.

“It’s absolutely the cold,” Parnia says, and one of his favorite examples is the Titanic: If we knew then what we know now, Parnia says, almost all of those who died could have been saved, their causes of death ideal — drowning and hypothermia. “Today, we would not have necessarily declared those people dead — at least not in the irreversible and irretrievable sense,” he writes, and when he saw the James Cameron film again recently, he kept coming back to the same question: When did each of those people actually, really die?

Parnia says the most compelling case yet is that of a woman in Japan who was found in a forest; her body temp was 68 degrees Fahrenheit, and it’s estimated she was dead for five hours. Doctors worked on her for another six hours using state-of-the-art medical advances, including an ECMO machine, which provides the blood and oxygen needed to keep organs alive without a heartbeat.

“She walked out of the hospital, unimpaired,” Parnia says. “If doctors put together all the latest advances” — including a machine that performs CPR with far more precision than a human — “we can push back death longer than we ever thought possible.”

The problem, Parnia says, is that there is no external mandate for these protocols in the state or nationwide, no regulatory body in place, not enough doctors and nurses aware these advances exist.

New York City, however, is unique: In 2008, the FDNY — which provides EMS services — began cooling every dying patient intravenously and in 2009 announced that they would not take a patient to any facility that did not have a hypothermia unit. For this reason, every hospital in New York City now has one. Still, if you get dragged out of the East River four hours after drowning, whether you are brought back to life will depend on the doctor you get and the call he or she makes — precisely because there are no enforceable standards.

Even many in the medical community, Parnia says, are trying to comprehend the impact of these advances. “I’ll go to conferences, and someone will say to me, ‘Oh, that patient was clinically dead,’ and I’ll say, ‘No. They were dead.’ They can’t grasp it — this concept is so ingrained in our heads. We have this social and philosophical notion of death, but it’s biological.”

Parnia also thinks we should replace the term “near-death experience” with “actual death experience” and that resuscitation science can only benefit from taking such accounts seriously. “In medicine, we’ve brushed people who’ve had this experience aside,” he says.

Parnia has no religious belief in this area, he says, and is not out to prove whether there’s a heaven or a hell or an afterlife. “We have this horde of evidence of people who have recollections,” he says, and though such accounts have existed for thousands of years, they were rare until the invention of CPR. “There are many millions of them,” he says. “We try to explain [NDEs] as lack of oxygen, hallucinations — but there’s no evidence to show it’s chemical.”

The commonality and uniformity of these accounts, which cut across cultures and religions — even atheists share similar stories — are evidence, Parnia says, that the experience is real. He thinks that those who report nothing have forgotten, just as not recalling our dreams doesn’t mean we didn’t have them. “I think this is a universal experience,” he says. “I think it happens to all of us when we die.”

Among the most reported details: a beam of white light, overwhelming feelings of love and peace, the appearance of deceased loved ones, detailed reports on what doctors and nurses were doing and saying, wearing and even thinking while trying to revive the dead patient — all point to a consciousness, Parnia says, that lives after the body and brain have died. And that consciousness, as the late Nobel Prize-winning neuroscientist John Eccles believed, may be independent of the brain.

How long the experience lasts and just what it is — transitory? Does this consciousness itself eventually die? Are our brains simply capable of far more than we know? — will be further explained by those unwitting pioneers of the future who remain dead for days, weeks, months, years and then come back to tell.

“From a medical perspective, I think it’s very hard to argue that when somebody dies, they become annihilated,” he says. “What does that mean for our definition of death? Is this person viable for 24 hours, and if so, where are they? It’s unlikely to think that consciousness dies. The question is: For how long does it exist?”
