Second Brain Death Exam May Be Unnecessary, Hurt Organ Donation Rates

16.12.2010
Requiring a second exam on a person who is considered brain dead may be unnecessary, according to a study on the impact of a second brain death exam on organ donation rates. The research is published in the December 15, 2010, online issue of Neurology®, the medical journal of the American Academy of Neurology.

For the study, scientists reviewed the cases of 1,229 adults and 82 children ages one and older pronounced brain dead. The information was taken from the New York Organ Donor Network database during a 19-month period.

“One of the most disturbing findings of our study is the prolonged anguish imposed on grieving families in the intensive care unit waiting for the second brain death exam,” said study author Dana Lustbader, MD, FCCM, FCCP, with The North Shore LIJ Health System in Manhasset, New York. “Not only is the opportunity for organ donation reduced, but families may endure unnecessary suffering while waiting an average of 19 hours for the second exam to be completed.”

“Since organ viability decreases the longer a person is brain dead, our results show that conducting more than one brain death examination results in the loss of potentially life-saving organs,” reports Lustbader. “A repeat exam adds an extra day of intensive care resulting in additional costs of about a million dollars per year in the New York region alone.”

The study found that none of the people declared brain dead in the first exam were found to have restored brain stem function in the second exam.

Lustbader noted that 166 people, or 12 percent, sustained a cardiac arrest while awaiting a second exam or after the second exam, making them ineligible for organ donation.

The average time between the two exams in the study was 19 hours, three times longer than recommended by the New York State Health Department. As the time between exams increased, consent for organ donation decreased from 57 percent to 45 percent. In addition, refusal of organ donation increased from 23 percent to 36 percent as the time between exams increased.

In New York, the State Department of Health’s 2005 brain death guidelines require a breathing test and two clinical brain death exams, carried out six hours apart. In 2010, the American Academy of Neurology updated its brain death guidelines, which now call for only one brain death examination.

“These findings illustrate why there’s a crucial need to standardize approaches for determining brain death,” said Gene Sung, MD, MPH, of the University of Southern California in Los Angeles and a member of the American Academy of Neurology, who wrote an editorial regarding the article that is published in Neurology.

The American Academy of Neurology, an association of more than 22,500 neurologists and neuroscience professionals, is dedicated to promoting the highest quality patient-centered neurologic care. A neurologist is a doctor with specialized training in diagnosing, treating and managing disorders of the brain and nervous system such as Alzheimer’s disease, stroke, migraine, multiple sclerosis, brain injury, epilepsy and Parkinson’s disease.

Im Focus: Significantly more productivity in USP lasers

In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.

Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...

Im Focus: Novel silicon etching technique crafts 3-D gradient refractive index micro-optics

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.

Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...

Im Focus: Quantum Particles Form Droplets

In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.

“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...

Im Focus: MADMAX: Max Planck Institute for Physics takes up axion research

The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.

The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...
