This is secondary to the association of AV access with reduced vascular access-related events such as infection, thrombotic, and nonthrombotic complications [5]. In special circumstances, a temporary CVC may be required to manage a vascular access complication (<2 weeks). In such cases, a nontunneled CVC or nontunneled dialysis catheter may be used. The KDOQI guidelines considers it reasonable to use a nontunneled internal jugular CVC strictly for temporary purposes for a defined period of time such as <2 weeks or per institutional policy in order to reduce the risk of infection [5]. It is considered prudent to limit the use of such noncuffed, nontunneled dialysis catheters, with special Dialysis Fistula Malfunction consideration for patients requiring emergent access. As such, given the lower infection risk, tunneled CVCs are often used in preference to nontunneled CVCs. In the case of a tunneled dialysis catheter, there is no maximum time limit to CVC use. However, regular evaluation is needed to determine if the CVC offers the most appropriate means for dialysis access.
