Bloodstream infection derived from an intravascular catheter occupies an important position among the various types of nosocomial infection. It is therefore necessary to establish a system for preventing catheter infection not only as measures for each separate infection, but also for the entire hospital. Catheter infections are mainly caused by contamination of the connecting part of a transfusion line during the infusion of drug solution as well as by contamination of the part of the catheter inserted. Consequently, the greatest possible care should be taken in the preparation of aseptic transfusion and the prevention of contamination when connecting a transfusion line. In particular, there are problems with three-way stopcocks, management of hubs, frequency of transfusion line exchange, fat emulsion injection method, and blood preparation. It is most important to consider effective nutritional management methods that do not require the insertion of a central venous catheter.
血管内导管引起的血流感染在各类医院感染中占据重要地位。因此，有必要建立一套预防导管感染的系统，这不仅是针对每一种单独感染的措施，也是针对整个医院的措施。导管感染主要是由输液过程中输液管路连接部位的污染以及导管插入部位的污染引起的。因此，在无菌输液的准备过程以及连接输液管路时防止污染方面应格外小心。特别是，三通旋塞、接头管理、输液管路更换频率、脂肪乳剂注射方法和血液制备存在问题。考虑采用不需要插入中心静脉导管的有效营养管理方法最为重要。
