[Expert consensus on clinical application of multi-chamber bag for parenteral nutrition (2022)].

Parenteral nutrition has become a routine clinical nutritional treatment. The guidelines at home and abroad unanimously recommend and standardize the application of "all in one" parenteral nutrition."Multi-chamber bag" parenteral nutrition encapsulates nutrients such as fat emulsion, amino acid and glucose in a non polyvinyl chloride soft bag composed of two or three cavities. When in use, the inner cavity separator is opened. The multi-chamber bag preparation has a variety of specifications and has the characteristics of reasonable prescription, strict quality standards, ready-to-use, and other characteristics, which can reduce prescription and configuration errors, reduce bloodstream infections, and meet the clinical nutritional needs of most patients. In view of the non-standard application of multi-chamber bag, the Chinese Society for Parenteral and Enteral Nutrition organized domestic experts in general surgery, critical care medicine, gastroenterology, geriatrics, nutrition, clinical pharmacy, and evidence-based medicine to write this expert consensus in accordance with the latest guidelines, expert consensus, and the latest clinical evidence. According to the improved Delphi method, 43 experts discussed and modified 23 recommendations one by one in the first round, and 219 experts voted and put forward modification suggestions in the second round. Each recommendation shall be established only when the approval rate of ≥ 90%. It is hoped that this consensus can promote the rational application of multi-chamber bag for parenteral nutrition.肠外营养是临床常规治疗方法，国内外指南中一致推荐规范应用“全合一”模式。肠外营养多腔袋将脂肪乳、氨基酸、葡萄糖等营养素分组封装于2个或3个腔组成的非聚氯乙烯软袋中，在使用时将内腔分隔带打开。多腔袋制剂有多种规格，具有处方合理、质量标准严格、即开即用等特点，可减少处方和配制差错，减少血流感染，满足多数患者的临床营养需求。针对肠外营养多腔袋在国内临床应用中的不规范现象，中华医学会肠外肠内营养学分会组织国内普通外科、重症医学科、消化科、老年医学、营养科、临床药学和循证医学等领域专家，遵循最新临床指南编撰国际标准，收集肠外营养多腔袋临床最新证据，参考国内外相关指南或共识，结合中国专家临床经验等，撰写本共识。遵循改良Delphi原则，首轮由40名专家对23条推荐意见进行逐条讨论及修改，二轮由219名专家进行投票并提出修改建议，每条推荐意见需获得≥90%的赞成率方为成立。希望本共识能够推动肠外营养多腔袋的合理应用。.
