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: Dresdner scientists print tomorrow’s world

The Fraunhofer IWS Dresden and Technische Universität Dresden inaugurated their jointly operated Center for Additive Manufacturing Dresden (AMCD) with a festive ceremony on February 7, 2017. Scientists from various disciplines perform research on materials, additive manufacturing processes and innovative technologies, which build up components in a layer by layer process. This technology opens up new horizons for component design and combinations of functions. For example during fabrication, electrical conductors and sensors are already able to be additively manufactured into components. They provide information about stress conditions of a product during operation.

The 3D-printing technology, or additive manufacturing as it is often called, has long made the step out of scientific research laboratories into industrial...

Nanometer-scale magnetic perforated grids could create new possibilities for computing. Together with international colleagues, scientists from the Helmholtz Zentrum Dresden-Rossendorf (HZDR) have shown how a cobalt grid can be reliably programmed at room temperature. In addition they discovered that for every hole ("antidot") three magnetic states can be configured. The results have been published in the journal "Scientific Reports".

Physicist Dr. Rantej Bali from the HZDR, together with scientists from Singapore and Australia, designed a special grid structure in a thin layer of cobalt in...
