血管通路器械的合理选择和规范管理是消化系统肿瘤治疗中亟待解决的问题。本共识的目的是制定消化系统癌症患者静脉血管通路装置安全管理的解决方案，并为临床决策提供依据。本共识由中国医疗保健国际交流促进会临床营养健康分会、中国营养学会临床营养分会、中国肠外肠内营养学会多学科专家共同制定。它基于当前最佳证据并结合中国临床实践经验。这些建议围绕以下主题进行了讨论：如何为消化系统癌症患者选择血管通路装置；外周插入中心导管的穿刺部位和尖端定位的最佳选择；中心静脉置管术后并发症的预防和处理；预防和治疗中心静脉导管阻塞的策略；中心静脉导管拔除标准；消化系统癌症患者使用静脉港通路的指征和外周静脉导管的标准。

The rational selection and standardized management of vascular access devices is an urgent issue in the treatment of digestive system cancer. The purpose of this consensus is to develop solutions for the safe management of intravenous vascular access devices for patients with digestive system cancer and to provide evidence for clinical decision-making. This consensus is developed by a group of experts from multiple-disciplines in China International Exchange and Promotive Association for Medical and Health Care Clinical Nutrition Health Branch, Clinical Nutrition Branch of Chinese Nutrition Society, Chinese Society for Parenteral and Enteral Nutrition. It is based on the best current evidence and combined with Chinese clinical practice experience. The recommendations were discussed and on the following topics: how to choose vascular access devices for patients with digestive system cancer; optimal selection of puncture sites and positioning of the tip for peripherally inserted central catheters; prevention and management of complications post-central venous catheterization; strategies for prevention and treatment of central venous catheter occlusion; criteria for central venous catheter removal; indications for the use of venous port access and criteria for peripheral venous catheter in patients with digestive system cancer.
