The use of fetal and anencephalic tissue for transplantation.

Advances in transplantation have extended the life and relieved the suffering of thousands of individuals. The prospect of being able to use tissues from embryos, as well as from anencephalic newborns, offers the promise of further relief of suffering. However, these possibilities raise significant moral and public policy issues. The question arises of the extent to which those who disapprove of abortion may make use of tissues derived from abortion in order to treat serious diseases. This essay argues that, with proper safeguards, such tissue can be used without cooperating in abortion. That is, even those who oppose abortion can benefit from the use of tissue procured during abortion. Questions also arise regarding the probity of maintaining a pregnancy in order to produce an anencephalic newborn whose biological existence will be maintained so as better to secure organs once death is declared. It is argued that, since no harm can be done to a being that has neither a sense of self or the capacity to feel pain, and since women have a right to forego abortions, there is no legitimate ground for opposing women's seeking meaning in their pregnancy through maximizing the opportunity of others to use the organs of their anencephalic newborn once death has been declared. Finally, it is argued that, since the capacities for sentience, a minimal condition for personhood, are never realized by an anencephalic, the entity has never been alive as a person. Therefore, there should be no opposition in principle to aborting anencephalics nor, after proper declaration, to making their organs available as one would after whole-brain death, despite the continued functioning of the brain stem.

Withholding medical treatment from the severely demented patient. Decisional processes and cost implications.

We performed an observational study to determine the prevalence of severe dementia in a general medicine unit, the categories of acute medical care provided to these patients, the process by which treatment decisions are made, and their cost implications. The prevalence of severe dementia was 4.4%. The patients from whom some form of acute medical care was withheld (26 [45.6%] of 57) were more severely ill at admission and had a mortality rate five times higher than those who received full care. Physicians cited family wishes in 75.9% of the decisions to limit care but in only 10.9% of the decisions to give full care. The only differences in charges incurred were due to differential mortality rates in individuals from whom care was withheld. We recommend that hospitals develop and implement protocols for decision making in the care of the severely demented to promote open discussions among providers and families and to increase family contributions to decision making. We believe that the extension of this consultative approach to decisions involving severely demented patients may have the virtue of combining more humane care with more cost-effective care.

Fetal ventricular pacing for hydrops secondary to complete atrioventricular block.

The advent of ultrasound recording has expanded the capabilities for treatment of the fetus in utero. The diagnosis of specific disease processes has allowed for prenatal intervention by new techniques designed to improve fetal survival. The application of ventricular pacing in a hydropic fetus with complete atrioventricular (AV) block is reported. Complete AV block resulted from maternal collagen vascular disease. The application of ventricular pacing was to allow for further in utero development and for reversal of hydrops fetalis after improvement in cardiac output. Despite fetal death 4 hours after placement of the ventricular pacing lead, this procedure when applied earlier in the development of hydrops may allow for fetal survival. Ventricular pacing was accomplished without apparent trauma to mother or fetus and no evidence of fetal injury was seen at necropsy. Therefore, in the fetus who would otherwise die in utero before the point of viability ex utero, fetal ventricular pacing may be a rational alternative to current observation.
