To cast light on the effects of aging on the metabolic responses to physical trauma an Ottawa researcher has studied strength and blood glucose metabolism in elderly people. He finds that because older people have less lean body mass, particularly muscle mass, than younger people, they are less able to tolerate trauma. They weaken faster and to a greater extent than younger patients who have experienced similar trauma, and they recover more slowly. At the same time, elderly people are less able to tolerate glucose, which is often given as part of their nutritional support. These findings have implications for care: the elderly trauma patient will be weaker than a younger counterpart, and nutrition will need to be provided early, with the glucose intolerance of elderly people borne in mind.
为了阐明衰老对身体创伤代谢反应的影响,渥太华的一位研究人员对老年人的力量和血糖代谢进行了研究。他发现,由于老年人的瘦体重,尤其是肌肉量,比年轻人少,他们对创伤的耐受性较差。与经历过类似创伤的年轻患者相比,他们衰弱得更快、程度更大,恢复也更慢。同时,老年人对通常作为营养支持一部分给予的葡萄糖耐受性也较差。这些发现对护理具有启示意义:老年创伤患者会比年轻患者更虚弱,需要尽早提供营养,并要考虑到老年人的葡萄糖不耐受情况。
