Tunneled catheters intended for dialysis are not suitable for power injecting contrast due to their design and material properties. These catheters are primarily made for hemodialysis access and may not withstand the high pressures generated by power injection. Using them for this purpose could lead to complications such as catheter rupture or thrombosis, potentially causing harm to the patient.

In cases where contrast media needs to be administered, intravenous access devices specifically designed for high-flow rates and pressure, such as dedicated power-injectable catheters, should be used instead. This ensures both the integrity of the catheter and patient safety.

Although certain clinical situations might prompt the consideration of alternatives, the standard guidelines clearly advise against the use of dialysis catheters for contrast injection, reinforcing the importance of selecting the proper vascular access devices for such procedures.
