多种微量元素注射液可以提供铁、锌、铜、锰、钴、氟、碘、硒、钼、铬等多种人体微量元素，广泛应用于需要肠外营养 治疗的患者。为了进一步提高临床医师对多种微量元素注射液的认识，更好地指导其临床合理用药，特邀请全国专家组成员， 在系统性文献检索的基础上，参考欧洲临床营养与代谢学会（ESPEN）、美国肠外与肠内营养学会（ASPEN）指南，结合我国临床 实践，经多次交流讨论，达成此共识。本共识基于临床研究证据和专家经验，为多种微量元素注射液临床用于危重症、中重度 烧伤、围手术期、肿瘤、老年、透析、肠瘘及短肠综合征等提供参考。

The multi⁃trace elements injection could provide many trace elements for human body, such as iron, zinc, copper, manganese, cobalt, fluorine, iodine, selenium, molybdenum and chromium, and is widely used in patients who need parenteral nutrition. To further improve the clinician′s understanding of multi⁃trace elements injection and better guide the rational clinical application, we invite the national expert group members to formulate a consensus paper. The consensus paper is a composite of systematically reviewing pertinent literature, Chinese clinical practice, and multiple sessions of debate, discussion, and composition, with reference to guidelines from European Society for Parenteral and Enteral Nutrition (ESPEN) and American Society for Parenteral and Enteral Nutrition (ASPEN). This consensus is based on clinical research evidences and experts′ experience, which will provide references for the clinical use of multi⁃trace elements injection in critically illness, moderate to severe burn, perioperative period, cancer, elderly, dialysis, intestinal fistula and short bowel syndrome.
