肠外营养技术的进步

Advances in parenteral nutrition technology

肠外营养是胃肠道功能严重障碍和(或)肠内营养不能满足能量需求的各类患者必需的治疗手段。近年来,肠外营养技术的进步可以体现在理念(补充性肠外营养)、配方(优化营养素组成)、制剂(工业化的多腔袋)等3个方面。补充性肠外营养的核心是在肠内营养基础上的肠外营养,既维护肠屏障功能,又能较快达到目标喂养量,满足机体代谢需求。优化营养素组成,充分发挥不同营养素的药理作用,进行代谢调理,维护器官功能。工业化生产的多腔袋肠外营养制剂,符合“全合一”的理念,使用方便,可减少处方和配置差错,降低感染并发症和医疗费用,适合病情稳定和短期应用肠外营养的患者。

Parenteral nutrition is a necessary treatment for patients with severe gastrointestinal dysfunction and(or)failure of enteral nutrition to meet their energy needs.In recent years,the progress of parenteral nutrition technology can be reflected in three aspects:concept(supplemental parenteral nutrition),formulation(optimization of nutrient composition)and preparation(industrial multi-cavity bag).The core of supplemental parenteral nutrition is parenteral nutrition based on enteral nutrition,which can not only maintain the intestinal barrier function,but also achieve the target amount of feeding quickly and meet the metabolic needs of the body.Optimize the composition of nutrients,give full play to the pharmacological effects of different nutrients,carry out metabolic conditioning,and maintain organ functions.The industrialized multi-cavity bag parenteral nutrition preparation conforms to the concept of“All-in-one”,is convenient to use,can reduce prescription and configuration error,reduce infectious complications and medical costs,and is suitable for patients with stable condition and short-term application of parenteral nutrition.
