A controversial topic in biomedical ethics concerns the moral status of embryos and fetuses and the rights that should be granted to them. Some argue that moral obligations such as beneficence and non-maleficence are owed to the fetus because it possesses a moral position. Others argue that the principle of autonomy is due to the mother carrying the fetus because it is her body and she has the right to make autonomous decisions regarding her health care. This article analyzes which biomedical principles cause conflict in cases involving mother-fetal problems and to whom the principles of biomedical ethics apply. Although this article examines ethical considerations as well as several theories and concepts regarding these issues, it concludes with a defense of my position on maternal-fetal issues and what I believe should be done in such cases.Analysis Ethics IntroductionMaternal-fetal issues generate complex and controversial debates in the field of biomedical ethics (Farber-Post, 1996). Conflicts arise when health professionals try to determine who has their ethical obligations. Many ethicists argue that autonomy is precedential and therefore it is the medical staff's duty to the pregnant mother because it is her body and she has the right to make decisions regarding her health care. health. Others argue that other, but equally important, ethical principles, such as beneficence, non-maleficence, and avoidance of killing, trump the principle of autonomy and that, therefore, these principles are due to the fetus. As seen in many cases, there are often conflicts between ethical principles. principles in the field of biomedical ethics. Case #2 is a perfect example of a case that begs the question of ethics...... middle of document ...... is not about ethical principles or even the conflict between them, but rather the determination to whom these principles are due and to what moral priority they relate. The ethical question in maternal-fetal conflict actually rests on how health professionals perceive the mother and fetus (American College of Obstetricians and Gynecologists, 2005). Staff may consider the pregnant mother to be a unique patient. That is, the fetus is nothing more than a part of a woman's body. Proponents of this vision argue that biomedical commitments and principles are due only to the pregnant woman. In contrast, others believe that a pregnant woman is actually two individuals and that the commitment to ethical principles applies to both patients. If we believe that there are indeed two patients, how do doctors, nurses and residents determine which principle is more important ??
