The question over whether to administer clinically assisted nutrition and hydration (CANH) to a dying patient is controversial, with much debate concerning this sensitive issue. The administration of CANH poses clinical and ethical dilemmas, with supporting and opposing views. Proposed positive effects of CANH include preventing thirst, delirium, hypercalcemia, and opioid toxicity. However, CANH has been shown to increase the risk of aspiration, pressure ulcers, infections, and hospital admissions as well as potentially causing discomfort to the patient. Guidance from several national bodies generally advises that the risks and burdens of CANH outweigh the benefits in the dying patient. However, an individualized approach is needed, and the patient's wishes regarding CANH need consideration if they have capacity and can communicate. Otherwise, sensitive discussions are required with the family, enquiring about the patient's prior wishes if there is no advanced care plan and acting in the patient's best interests. The ethical principles of autonomy, beneficence, non-maleficence, and justice need to be applied being mindful of any cultural and religious beliefs and potential misperceptions.
是否向临终患者提供临床辅助营养和水合(CANH)的问题存在争议,围绕这一敏感问题存在很多争论。给予 CANH 会带来临床和伦理上的困境,支持和反对的观点都有。CANH 的拟议积极影响包括预防口渴、意识混乱、高钙血症和阿片类药物毒性。然而,CANH 已被证明会增加患者发生吸入、压疮、感染和住院的风险,并可能导致患者不适。几个国家机构的指南通常建议,在临终患者中,CANH 的风险和负担超过了益处。但是,需要采取个体化的方法,如果患者有能力并且能够进行沟通,就需要考虑他们对 CANH 的意愿。否则,如果没有预先的护理计划,就需要与家属进行敏感的讨论,询问患者之前的意愿,并以患者的最佳利益为出发点。在应用自主、善行、不伤害和公正的伦理原则时,需要考虑到任何文化和宗教信仰以及潜在的误解。
