In 2002, I wrote a paper titled “Ethical Implications of Non-Heart-Beating Organ Donation” (NHBD) and presented it at Trinity College at a medical ethics conference. At that time, brain death organ donation was well-known, but NHBD was virtually unknown to the public although it comprised about 2% of organ donations at that time.
As I wrote then:
“It is now apparent that the number of organs from people declared brain dead will never be enough to treat all patients who need new organs. ” and “doctors and ethicists have turned to a new source of organs — patients who are not brain dead but who are on ventilators and considered “hopeless”. In these patients, the ventilator is withdrawn and organs are quickly taken when cardiac death (DCD) rather than brain death is pronounced.”
Now, the term “Donation after Circulatory Death” (DCD) is used instead and means:
“Circulatory death occurs when the heart has irreversibly stopped beating and when circulation and oxygenation to the tissues irreversibly stops.” (Emphasis added)
However, with heart transplantation, the heart will be restarted as explained in a March 24, 2023 Medscape article “A ‘Game Changer’ for Heart Transplant: Donation After Circulatory Death Explained”.
In the article, Adam D. DeVore, MD, MHS is interviewed by Ileana L. Piña, MD, MPH and explains how this works and why he is excited:
“Adam D. DeVore, MD, MHS: In the field of heart transplant, DCD or donation after circulatory death is really a game changer. For decades now, we’ve been doing heart transplants from donors who die or have been declared brain dead.
There’s a whole population of potential donors who have very similar neurologic injuries — they’re just not technically declared brain dead — whose organs the family would like to donate. We didn’t have a way before.”
“There are two mechanisms. The family would withdraw care. Somebody affiliated with the hospital would declare that the donor has died. There’s usually a standoff period. That is a little variable, but it’s around 5 minutes.” (All emphasis added)
and added that then:
“…There are then two ways where that heart could be resuscitated or revived, outside the body on the organ care system. Or it could remain in the body through normothermic regional perfusion (NRP), or they’ll go on cardiopulmonary bypass and re-perfuse the heart in the room, and then look at the heart and try to evaluate it before donation. The rest of that donation looks just like every other brain-dead donation.”
…I remember when we were first starting this, I was thinking of how we would explain this to potential recipients and what would this look like. It turns out that something terrible has happened, and families that want to donate organs are relatively enthusiastic and less focused on the details.” (All emphasis added)
ETHICAL CONCERNS
In another March 23, 2023 Medscape article titled “Does New Heart Transplant Method Challenge Definition of Death?, Sue Hughes, a journalist on Medscape Neurology, writes:
“The difficulty with this approach, however, is that because the heart has been stopped, it has been deprived of oxygen, potentially causing injury. While DCD has been practiced for several years to retrieve organs such as the kidney, liver, lungs, and pancreas, the heart is more difficult as it is more susceptible to oxygen deprivation. And for the heart to be assessed for transplant suitability, it should ideally be beating, so it has to be reperfused and restarted quickly after death has been declared.” (Emphasis added)
When the NRP technique was first used in the US, these ethical questions were raised by several groups, including the American College of Physicians (ACP).
“The difficulty with this approach, however, is that because the heart has been stopped, it has been deprived of oxygen, potentially causing injury. While DCD has been practiced for several years to retrieve organs such as the kidney, liver, lungs, and pancreas, the heart is more difficult as it is more susceptible to oxygen deprivation. And for the heart to be assessed for transplant suitability, it should ideally be beating, so it has to be reperfused and restarted quickly after death has been declared.” (Emphasis added)
Harry Peled, MD, Providence St Jude Medical Center, Fullerton, California, co-author of a recent Viewpoint on the issue said that:
“There are two ethical problems with NRP, he said. The first is whether by restarting the circulation, the NRP process violates the US definition of death, and retrieval of organs would therefore violate the dead donor rule.
“American law states that death is the irreversible cessation of brain function or of circulatory function. But with NRP, the circulation is artificially restored, so the cessation of circulatory function is not irreversible,” Peled points out.
The second ethical problem with NRP is concern about whether, during the process, there would be any circulation to the brain, and if so, would this be enough to restore some brain function? Before NRP is started, the main arch vessel arteries to the head are clamped to prevent flow to the brain, but there are worries that some blood flow may still be possible through small collateral vessels.” (Emphasis added)
Nader Moazami, MD, professor of cardiovascular surgery, NYU Langone Health, New York City, is one of the more vocal proponents of NRP, stating that:
“”Our position is that death has already been declared based on the lack of circulatory function for over 5 minutes and this has been with the full agreement of the family, knowing that the patient has no chance of a meaningful life. No one is thinking of trying to resuscitate the patient. It has already been established that any future efforts to resuscitate are futile. In this case, we are not resuscitating the patient by restarting the circulation. It is just regional perfusion of the organs.” and “We are arguing that the patient has already been declared dead as they have a circulatory death. You cannot die twice.” (Emphasis added)
CONCLUSION
Ms. Hughes also wrote in her article that:
“Heart transplantation after circulatory death has now become a routine part of the transplant program in many countries, including the United States, Spain, Belgium, the Netherlands, and Austria.”
And in the US, “348 DCD heart transplants were performed in 2022, with numbers expected to reach 700 to 800 this year as more centers come online.” And “It is expected that most countries with heart transplant programs will follow suit and the number of donor hearts will increase by up to 30% worldwide because of DCD. ”
So how important is it to have strict medical ethics standards in organ donations?
In a February 9, 2023 Transplant International article titled “Organ Donation After Euthanasia in Patients Suffering From Psychiatric Disorders: 10-Years of Preliminary Experiences in the Netherlands“, it was reported that:
“Over the ten-year study period 2012–2021 59,546 patients underwent euthanasia of whom 58,912 suffered from a somatic (physical) disorder. The number of patients that underwent euthanasia for an underlying psychiatric disorder was 634 (1.1%). An estimated 10% (5955) of patients who undergo euthanasia in general are medically eligible to donate one or more organs (11).” (Emphasis added)
Organ transplants can be wonderful and lifesaving, but we must know all the facts, be able to trust our healthcare providers, and especially not allow the “slippery slope” of legalized assisted suicide/euthanasia to get any steeper.
