近年来,临床营养支持逐渐被广大医生所接受。根据患者的体质及疾病,为其制定合适的营养支持是非常重要的。在现代医学中,随着对不同危重病人病理与生理代谢差异的研究,证明了危重病人因高代谢状态导致严重的营养代谢障碍和免疫衰竭,从而易发生难以控制的感染和不可逆的细胞功能损害,甚至因此而加重病情,导致病人死亡。传统的营养营养支持通过喂养管经胃肠道途径的方法。随着临床营养支持的发展,使营养支持方式逐渐转变为通过鼻胃/鼻空肠导管或胃/肠造口途径为主的肠内营养支持。这种转换是基于我们对营养及其供给方面的深入了解和认识。设计较好的RCT及有外科病人的荟萃分析结果显示,PN
In recent years, clinical nutrition support gradually accepted by the majority of doctors. According to the patient’s constitution and disease, to develop appropriate nutrition support is very important. In modern medicine, with the study of pathological and physiological metabolic differences among different critically ill patients, it is proved that critically ill patients suffer severe nutritional and metabolic disorders and immune failure due to their high metabolic status, so that uncontrollable infection and irreversible impairment of cellular functions are easy to occur , And even aggravate the condition, resulting in the patient’s death. Traditional nutritional nutrition supports feeding through the gastrointestinal tract approach. With the development of clinical nutritional support, nutritional support has gradually been transformed into enteral nutrition support through the nasogastric / naso-jejunal catheter or the stomach / gastrectomy pathway. This conversion is based on our in-depth knowledge and understanding of nutrition and its supply. A well-designed RCT and a meta-analysis of surgical patients showed that PN
