Abstract: Central venous catheter is an important type of vascular access, among which tunneled cuffed central venous catheter (TCC) is increasingly used and has been adopted by many institutions in China. However, due to inconsistencies in concepts and techniques across different institutions, some demonstrate deficiencies in the indications for TCC insertion, replacement, and removal, as well as in procedural standardization and operational risk management. Given that TCC insertion and replacement are inherently high-risk procedures, non-standard practices may lead to complications such as asphyxia, catheter dysfunction, and catheter-related infections, which can severely affect patients' dialysis outcomes and quality of life. Meanwhile, many institutions still require the performance of TCC insertion, replacement, and removal. In view of this, an expert consensus panel established a writing committee to systematically outline standardized oper ating procedures for the insertion, replacement, and removal of tunneled cuffed central venous catheters, integrating evidence-based consensus with clinical experience. It is hoped that under the guidance of this consensus, the techniques for TCC insertion, replacement, and removal in China can be further promoted, standardized, and refined, thereby benefiting a broader population of hemodialysis patients.
