Percutaneous endoscopic gastrostomy is an accepted technique for long-term enteral feeding. The demand of percutaneous endoscopic gastrostomy placement continues to increase because of the increasing numbers of vulnerable patients with chronic diseases coupled with the relative ease of insertion, and societal ambivalence about such treatment. Despite the demand and improvements in placement technique, the issue of tube feeding in vulnerable patients remains an ethical minefield, leading to considerable discussion and debate. This contentious area of clinical ethics is further complicated by the recent papal allocution regarding artificial nutrition and hydration. The case of Terri Schiavo should serve as a timely reminder of those problematic clinical and ethical issues inherent in percutaneous endoscopic gastrostomy placement and feeding in vulnerable patients.

Nurses are increasingly faced with situations in practice regarding the prolongation of life and withdrawal of treatment. They play a central role in the care of dying people, yet they may find themselves disempowered by medical paternalism or ill-equipped in the decision-making process in end-of-life situations. This article is concerned with the ethical relationships between patient autonomy and medical paternalism in end-of-life care for an advanced cancer patient. The nurse's role as the patient's advocate is explored, as are the differences between nursing and medicine when confronted with the notion of patient autonomy. The impetus for this discussion stems from a clinical encounter described in the following scenario.

Ethics is a hot topic these days. Home health care providers need not be ethicists, however they do need to be able to identify problems quickly, and know how to address them. This paper explores the ethical issues arising from a narrative analysis involving an advanced cancer patient receiving Total Parenteral Nutrition (TPN) at home. It shows how complicated it is today to make nutrition support decisions that would have been customary less than 30 years ago. For and against arguments of TPN for advanced cancer patients are reviewed. Ethical positions adopted by the medical and nursing professions are explored and contrasted. The importance of patient autonomy, within a holistic notion of care, including decisions incorporating quality of life, are affirmed, providing a challenge to monitoring the status quo in approaches to decision making.
