First National Rules for Controversial Organ Recovery Procedure Take Effect Dec. 6
The U.S. organ transplant system's first national NRP guidelines take effect Dec. 6, but bioethicists say they fail to resolve whether donors are truly dead when organs are removed.

In brief
- The OPTN board approved the first national NRP guidelines on Nov. 6; they take effect Dec. 6.
- More than 109,000 Americans are on the transplant waitlist; about 12 die daily waiting.
- NRP restarts circulation in dead donors' organs with an external pump to preserve them for transplant.
- New rules require venting brain blood vessels and discourage paralyzing drugs that could mask movement.
- Critics say NRP violates the Dead Donor Rule and the policy adds little to existing surgeon practice.
On Dec. 6, the first uniform national guidelines for a controversial organ-recovery procedure take effect across the U.S. transplant system — and critics say they change almost nothing.
The procedure is called normothermic regional perfusion, or NRP. Doctors use it after a family decides to withdraw care because there is no hope of meaningful recovery. Minutes after the patient's circulation stops and a doctor declares them dead, surgeons attach an external pump. That pump restores blood flow to the heart, lungs, kidneys, liver and other organs, keeping them from deteriorating before transplant.
The stakes are enormous. More than 109,000 Americans are waiting for an organ transplant, according to the Health Resources & Services Administration, the federal agency that oversees the system. About 12 die every day because of the chronic shortage.
"The hope with NRP is that it increases the supply of organs and it increases the quality of the organs," says Dr. Raymond Lynch, director of transplantation at HRSA. More organs, better organs, fewer deaths. That's the promise.
But every promise here comes with a caveat, and this one is philosophical as much as medical.
What is the Dead Donor Rule?
Transplant medicine rests on a principle called the Dead Donor Rule: surgeons can only take organs from patients declared dead — by brain death or circulatory death. NRP, critics argue, breaks that rule in plain sight. By restarting circulation with a pump, the procedure reverses the very condition upon which the person was just declared dead.
"In order to be dead by circulatory criteria it means we're not going to attempt to reestablish circulation. But that's exactly what they do in NRP," says Dr. Lainie Friedman Ross, a University of Rochester bioethicist. "So, yes, I have a real problem with NRP. I think it violates the dead donor rule. It's taking organs from people who are no longer dead."
That's a serious charge. And it's not the only one.
Why did the alarm bells go off?
To make sure a donor is brain dead once the pump restarts circulation, surgeons clamp off the blood vessels supplying the head. In some NRP cases, blood nonetheless reached — or "reperfused" — the brain.
"We have seen signs of life in NRP when the brain has been reperfused," says Dr. Claire Morgan, a transplant surgeon on the transplant network's Patient Affairs Committee who first reported such cases to HRSA. "It's extremely disturbing."
Those reports pushed HRSA to instruct the Organ Procurement & Transplantation Network, which runs the organ system, to investigate. On Nov. 6, the OPTN board of directors approved the first phase of the first national NRP guidelines.
The new policy:
- Requires surgeons not just to clamp head blood vessels but also to cut holes in them — "venting" — so that if clamping fails, blood immediately drains out rather than supplying warm, oxygenated flow to the brain.
- Recommends against giving donors drugs that would paralyze them and mask any movements.
"Clamping the blood vessels should stop blood flowing to the brain," Lynch says. "Cutting or venting above the level of the clamping is a second safeguard."
What does this change for donors and families?
Not much, according to the critics — and this is where the story gets uncomfortable for the regulators.
Morgan points out that most surgeons already both clamp and vent. "I honestly don't believe they have created a policy that creates much or any more protection than these donors already had," she says. She also objects to the guidelines being implemented on an emergency basis, before the public had any chance to weigh in.
The deeper objection remains untouched: critics say NRP donors are not technically dead when their organs are removed, and they worry the new policy will speed NRP's adoption before that question is fully aired.
"I really think the policy is the cart before the horse," says Dr. Matthew DeCamp, a University of Colorado bioethicist. "The fundamental issues around NRP still remain unresolved."
Lynch disagrees, and defends both the procedure and the policy. "This is an important first step to make sure NRP care is available but that the safety of the family's loved one is always at the forefront," he says. "This is life-saving care that will extend the supply and improve the quality of organs. And if it is done properly, it is safe."
If. That word is carrying a lot of weight. Twelve deaths a day give the urgency; the Dead Donor Rule gives the unease. The guidelines land Dec. 6 regardless, and the ethical argument — whether restarting a heart means restarting a life — stays exactly where it was.
