Grades 9-12. This detailed book looks at a host of issues brought to the fore by the advances of medical technology in the last few decades. Bioethics describes the questions of right, wrong, fairness, and justice that arise when new discoveries in the biological sciences are applied to the practice of medicine. What is life, how is death defined, and how does quality influence them both? Gene therapy, surrogate motherhood, euthanasia, assisted suicide, artificial nutrition and hydration, and living wills are all examined in the light of recent well-known examples and court cases. Regarding aggressive or nonaggressive care of disabled infants, who makes the decisions--parents, doctors, the hospital, or society at large? A chapter is devoted to costs, and the ethics connected with the allocation of such expensive treatments as kidney dialysis and organ transplants. Chronic illness, tissue transplants, and experimental cancer treatments all expose troublesome ethical questions with which patients and doctors alike are struggling. A final chapter deals with abortion and the influence of recent technology such as amniocentesis and ultrasound. The book contains a useful glossary, footnotes, and suggested readings. It is written without bias, yet with a sense of urgency that these issues must be examined, as they are shaping tomorrow's personal and societal values.
