POWER INJECTION PROCEDURE:
Before proceeding follow institutional protocol to verify correct
catheter tip position via radiographic image prior to power injection.
1. Access the port with an appropriate non-coring needle. Make
certain that needle tip is inserted fully within the port.
Warning: The Power Injectable Implantable Infusion Port is
only power injectable when accessed with a power injectable
needle.
2. Attach a syringe filled with sterile normal saline.
3. Instruct the patient to assume the position they will be in during
the power injection procedure, before checking for patency. If
possible, the patient should receive power injection with his or her
arm vertically above the shoulder with the palm of the hand on the
face of the gantry during injection. This allows for uninterrupted
passage of injected contrast through the axillary and subclavian
veins at the thoracic outlet.
4. Aspirate for adequate blood return and vigorously flush the port
with at least 10ml of sterile normal saline.
Warning: Failure to ensure patency of the catheter prior to power
injection studies may result in port system failure.
5. Detach syringe.
6. Warm contrast media to body temperature.
7. Attach the power injection device to the needle ensuring connection
is secure. Check indicated flow rate and confirm CT settings.

8. Instruct the patient to communicate immediately any pain or
change in feeling during the injection.
9. Inject warmed contrast, taking care not to exceed the flow rate
limits.
Warning: If local pain, swelling or signs of extravasation are noted,
the injection should be stopped immediately.
Warning: Exceeding the maximum flow rate may result in port
system failure and/or catheter tip displacement.
10. Disconnect the power injection device.
11. Flush the port with 10ml of sterile normal saline.
12. Perform heparin lock procedure. Remember that some patients
may be hypersensitive to heparin or suffer heparin induced
thrombocytopenia (HIT). These patients must not have their port
primed with heparinized saline.
13. After therapy completion, flush port per institutional protocol.
Close clamp while injecting last 0.5ml of flush solution.
Warning: Do not exceed a 325 psi pressure limit setting, or the
maximum flow rate setting shown below, on the power injection machine
if power injecting through the Power Injectable Implantable Infusion Port.
The CT Implantable Port system testing included at least
