中文摘要 | 住院病人常出現微量營養素 (micronutrient) -維生素 (vitamin)和微量元素 (trace element)缺乏。不均衡的飲食、身體需求量增加或身體營養流失,都可能導致微量營養素的缺乏。微量營養素不足會影響到體內的生物化學反應以及酵素功能,進而導致器官的機能障礙、肌肉無力、傷口不易癒合以及免疫功能的改變。雖然目前針對健康成人的微量營養素攝取,已建立 13種維生素和 10項必需微量元素的每日建議量,但是重大疾病患者對於微量營養素的需求量,仍不是那麼清楚。多數腸道營養補充劑都含有適量的維生素和微量元素,但是生體利用率的多寡是相當大的變異因子。臨床在進行微量營養素補充時,可能不能單單以營養補充的觀點來思考,可能要進一步以營養治療的方式進行考慮。 |
英文摘要 | Micronutrient (vitamins and trace elements) deficienciesare often present in hospitalized patients. Deficiencies occur due to inadequate administration, increased requirements, and increased losses, affecting various biochemical processes and resulting in organ dysfunction, poor wound healing, and altered immune status. Guidelines for the 13 essential vitamins and 10 essential trace elements have been established. These recommendations, however, are not to critically ill patients. Most enteral nutrition preparations contain adequate amounts of vitamins and trace elements, although bioavailability may be an issue. Clinicians think of micronutrients should not as nutritional supplements alone but also as therapeutic agents. |
