Lying motionless on a crisp sheet, the 17 year-old resembles a dis- heveled department store manne- quin. The dull, artificial quality of her arms and legs is accentuated when the nurse by her bedside grips the patient's forearm, lifts it up- ward, and slides a hypodermic needle into her flesh. "No pain response," says Dr. Joel Saper, standing at the foot of the bed in the University Hospital's in- tensive care ward. As Saper approaches to take a closer look at Marla, the nurse gen- tly pulls out the hypodermic needle and lowers Marla's arm to the bed. It lies still, palm up, sallow. Marla's jaw remains slack as Sa- per lifts her eyelid and shines a penlight at the pupil. He gingerly touches her face to avoid knocking the plastic tube running into her nostril w h i c h maintains her breathing. "The pupils don't con- strict," he notes. He gently lets her head go, and it rolls slightly on the pillow. Marla-not her real name-had tried to kill herself with an over- dose of sleeping pills. She was rushed to the hospital, her stomach pumped, and as her breathing slow- ed to a halt, she was wheeled to in- tensive care and attached to a res- pirator. 'THREE SMALL television screens a few feet from her bed moni- tor her heart and breathing rates and brain wave activity. The pulse and respiration rate show up as uniform, jagged lines on the screens. But the brain activity graph, or electroencephalograph (EEG), is flat. No apparent brain waves. The reason that Marla's brain activity is dormant may be only that she has taken a drug overdose. For up to two weeks after a person has taken a large quantity of bar- biturates, EEG activity can be tem- porarily suppressed, only to start up again when the drug is com- pletely purged from the system. If the barbiturate still in her blood- stream is the cause of her flat EEG, she could be on the road to recov- ery. 'Whenever the plug is pulled on a respirator, the patient is already dead. I've n e v e r seen a plug pulled on a living patient.' -Dr. Joel Saper to transplant organs. As the de- mand for organ donors increased, doctors began to look for ways to quickly determine whether coma- tose patients are alive or dead. Transplantable organs are often needed in a hurry. And the longer a patients stays in a coma, the more the body deteriorates. A team of doctors has been or- ganized at University Hospital to make fast decisions at any time of the day or night on whether a co- maose patient is alive. The group is called the Cerebral Death Determ- ination Committee. "R. MARTHA WESTERBERG, a neurologist and one of the six physicians on the committee, ex- plains that the group is "set up to deal only with patients who are to be used as donors. "Others may ask our advice," she says, "but that's rare. People die everywhere in the hospital, and in most cases that's the responsibility of the doctor on duy." The "brain death committee," Westerberg says, consists of a pair of EEG experts, a pair of neurolo- gists, and a pair of neurosurgeons. Twenty-four hours a day, at least one doctor from each pair is avail- able to help decide whether a po- tential donor is dead. The doctor attending a comatose patient will always be an EEG ex- pert, a neurologist or a neurosur- beon. In deciding a patient's sta- tus, he or she will consult with two brain death committee members, one from each of the other two ca- teiz-ories. The committee uses a strict set of criteria, dictated by state law, for making its life or death judg- ments. One of the tests is to study Daily Photo by PAULINE LUBENS Dr. Joel Saper But things will not bode well for Marla if after two weeks her EEG remains flat. Even if the respirator '- her breathing and her heart continues beating, she may then be legally dead. * ~* * A BOUT 15 YEARS AGO, respira- tor machines caused a revolu- tion in the medical profession's " 'w of what constitutes death. Until then, the fact that a person was breathing and had a beating heart was considered evidence of life. But as the machine which keeps Marla alive came into more common use, it became clear that a person's heart and lungs can be made to work long after all other sig'ns of life have evaporated for good. Ton of death was EEG readings taken 24 hours apart. The patient is considered to be alive, Westerberg notes, if the graphs are not flat. But flat graphs are not considered evidence of death if the person has taken de- pressant drugs or has an abnorm- ally low body temperature. rFHE COMMITTEE ALSO consid- ers these characteristics, de- termined by clinical tests, to be evi- dence that a patient is dead: -- contracted pupils which do not respond to light; - no response to pain or other stimulation; - absence of all other than spin- al reflexes; and -inability to breathe or sustain circulation of the blood without ar- tificial support. Doctors on the wards treating comatose patients who are not to be organ donors use the same cri- teria for death but do not make decisions as quickly. When a patient is judged to be "brain dead," the respirator ma- chine keeping him or her alive can be disconnected. Neurologist Joel Saper, the physician who treated Marla, explains that even on the wards, the decision that a patient is dead is made by a group of doc- tors. "WHEN THE PLUG is pulled on a patient determined to be dead," he says, "it isn't an indivi- dual decision. Several doctors get together and all say, 'the person is dead'. So the respirator goes off." Is the plug ever pulled at 'U' Hospital on a patient who doesn't fill all the criteria for death? "No. Even if a patient was in so much pain that he wanted to be killed," Saper says, "under the law it's murder if the doctor pulls the plug on him or gives him a fatal shot of morphine. Personally, I wouldn't kill a patient even if it were legal. "Whenever the plug is pulled on a respirator, the patient is already dead. I've never seen a plug pulled on a living patient, and I've never seen a patient neglected." Leaning back in his chair in his small office at University Hospital, Saper tamps down a fresh tuft of tobacco in his pipe, lights it, and puffs, wrinkling his eyebrows. He brushes a morsel of tobacco from his white smock, and strokes his beard. "I'VE READ SOME charges that euthanasia is practised in some hospitals in the country, and I don't know if it's true," he re- marks. "But if it happened here, I'm pretty sure I would know about it. At teaching hospitals like this one, people know about what ev- eryone else is doing." "Sometimes, with certain pa- tients," he continues, "we think that because they'll be in pain or because their chances of making it are very small that maybe we shouldn't attach machines at all. We doctors might discuss that over coffee, but I don't know of anybody who doesn't try to keep that pa- tient alive when a life is actually on the line." See LIFE, Page 5 Sti, hheu Dire'cior.

By JEFF RISTINE 'HE QUESTION of whether sci- ence will serve the world or rear back and become its Franken- stein monster was graphically il- lustrated on a fateful day in Au- gust, 1945. The awesome destruc- tion wreaked on Hiroshima dem- onstrated convincingly that the ability to destroy the world was locked up in the atom. But, as time has shown, unleashing the armageddon-like forces of the atom has proved far easier than chan- nelling its terrifying energy into peaceful purposes. The power to destroy the world in a few, fiery hours provoked a spate of moral and philosophical questions. And not until recently, with the new DNA technology, has any scientific research provoked such intense debate. When recom- binant DNA research was unveiled about five years ago, scientists opened the door to an issue which has since become a national con- troversy. At one end of the DNA de- bate are certain scientists and an assemblage of optimistic support- ers who believe that this new re- search may help rid the world of numerous diseases, provide defense against allergies, vastly increase agricultural yields, and offer a less desirable consequences. The most extreme opponents warn of a genetic apocalypse - of a sud- den, unpredictable and irreversi- ble new disease which may kill human life and vegetation. While university researchers may have only the best intentions, some of the critics say, the ends toward which government or industry may work could be far less desirable. They urge that all risks be identi- fied and calculated before sci- entists ever tinker with the mi- croscopic gene. However, the potential dangers and benefits probably lie some- where between the scenarios paint- ed by the doomsayers and the rosy pictures offered by the scientists. The concerned layperson, who can now only guess at DNA's impact, is faced with a battery of statis- tics, probabilities, and promises of good faith on the one hand, and counterstatistics, skepticism, and pleas for caution on the other. And if the two sides share any thought about the research, it is the unsettling fear that there may never be a way to decide - to the satisfaction of all - who is right. THE QUESTION is difficult, be- cause it involves a substantial dose of highly technical issues, DNA, deoxyribonucleic acid, is a type of molecule found in the nucleus of virtually every cell in every organism. DNA molecules, which consist of two strands wound into parallel spirals (the double helix), are an important part of the study of biology because they form the basic units of heredity for the cells-genes. Therefore, if two organisms have different genetic material, it is because the bases (also called nucleotides) in' their DNA molecules are arranged differently, which means the genes will carry different "information." Recombinant DNA research is a broad term referring to a rela- tively new way to experiment with DNA molecules. Only a fraction of the experiments are considered risky at all, and a few of them have been banned by the scien- tists themselves. Recombinant DNA experiments essentially involve the transplant of genetic material from one cell into cells of a wholly different species - an action that never occurs in nature. Microbiologists remove tiny, circular DNA mole- cules called plasmids from the bac- terium of one species, split them open chemically, and attach new genes from a different species to the gap in the DNA plasmid.
