Withholding and withdrawing life-sustaining medical treatment are common in paediatric practice, especially in intensive care units. However, not all clinicians apparently adhere to principles in ethical guidelines or to the principles which are to be found in judgments from common law cases arising when doctors and parents dispute treatment. This article examines selected ethical guidelines and compares them to judgments in leading cases. The rationale to forgo treatment is usually the child's "best interests" in both clinical practice guidelines and legal cases but in the former "best interests" may remain ill defined. Although "best interests" must essentially pertain to the individual child, the interests of others are not irrelevant. In legal cases "best interests" of the child are defined in terms such as "burden versus benefit", "futility", "indignity", "intolerability", "prolonging death rather than saving life" and "quality of life". These or like terms should form the basis of ethical decisions in discussions with parents when contemplating withholding or withdrawing life-sustaining treatment. 相似文献

In this paper, we review the result of research conducted in the context of a 13-year collaborative partnership between DePaul University and a community-based, self-run, residential substance abuse recovery program called Oxford House. This collaborative effort highlights several examples of the research and action activities fostering a positive alliance that benefited both the research team and the Oxford House community. It also proposed practical guidelines for developing effective action research collaboratives that may be helpful to others who desire to cultivate and maintain similar mutually beneficial partnerships; including such processes as the development of trust, respecting the personal experiences of the community members and group, commitment to serving the community, validating findings with organization members, and accountability. 相似文献

The authors report on a drug fatality of a 21-year-old man with a propofol (2,6-di-isopropylphenol) dependency. Propofol was detected in tissues and body fluids using SPME-GC/MS methods. The postmortem concentrations of propofol were 364 ng/ml in urine, 71 ng/ml in heart blood and 79 ng/ml in femoral blood. The drug addict had only an autodidactic medical knowledge, but had inserted himself a permanent cannula for intravenous injection of propofol several times a day. The injection material was bought via online auctions from eBay. The case illustrates how job-related drug dependencies become indistinct due to the free access to information and goods via the Internet. 相似文献

Minor soft tissues injuries are common in both adults and children who have had cardiopulmonary resuscitation (CPR). Potentially life-threatening injuries are rare. The pre-arrest history in a resuscitated adult often assists the pathologist to interpret autopsy findings. In contrast, an infant or child may not have a reliable history. In this situation, it may be difficult if not impossible to distinguish resuscitation injuries from pre-existing accidental or inflicted trauma. I describe two children who had significant autopsy-documented injuries initially attributed to abuse. The State filed murder charges against the caretaker in each case. However, further history and review of the medical records suggested that resuscitation rather than pre-arrest trauma caused almost all of the injuries. The State dismissed the charges in the first case. A jury returned a "not guilty" verdict in the second. It is essential to consider the entire history and not just autopsy findings when performing a death investigation. 相似文献
