Caution: When introducer needle is used, do not withdraw
guidewire against needle bevel to avoid possible severing of
guidewire.
6. Remove the needle, leaving guidewire in the vessel. Enlarge
cutaneous puncture site with scalpel.
7. Thread the dilator over the proximal end of the guidewire.
Dilate subcutaneous tissue and vein wall to allow easy
passage into target vein.
Caution: Do not leave vessel dilator in place as an indwelling
catheter to avoid possible vessel wall perforation.
Caution: Insufficient tissue dilation can cause compression of the
catheter lumen against the guidewire causing difficulty in the
insertion and removal of the guidewire from the catheter. This can
lead to bending of the guidewire.
8. Irrigate catheter with saline, and clamp arterial extension. Use
clamps provided. Thread the catheter over proximal end
of the guidewire.
9. Ease the catheter through the subcutaneous tissue and into
the target vein.
10. Make any adjustments to catheter under fluoroscopy. The
distal tip should be located just before the junction of the
superior vena cava and the right atrium. Femoral placement
to be determined by physician.
11. Once proper placement is confirmed, remove guidewire and
stylet and close clamp.
12. Attach syringes to both extensions and open clamps. Blood
should aspirate easily from both arterial and venous sides. If
either side exhibits excessive resistance to blood aspiration,
the catheter may need to be rotated or repositioned to obtain
adequate blood flow.
13. Once adequate aspiration has been achieved , both lumens
should be irrigated with saline filled syringes using quick
bolus technique. Assure extension clamps are open during
irrigation procedure.
14. Clamp the extensions, remove the syringes, and place an
injection cap on each luer lock connector. Avoid air embolism
by keeping tubing clamped at all times when not in use and by
filling the catheter with saline prior to use. With each change
in tubing connections, purge air from the catheter and all
connecting tubing and caps.
15. Immediately after insertion, confirm proper placement of the
tip of the catheter with fluoroscopy.
Caution: Failure to verify catheter placement may result in serious
trauma or fatal complications.
CATHETER SECUREMENT AND WOUND DRESSING:
16. Suture the catheter to the skin using the suture wing. Do not
suture the catheter tubing.
17. Cover the insertion site with an occlusive dressing.
18. Catheter must be secured/sutured for entire duration of
implantation.
19. Record catheter length and catheter lot number on patient's
chart.
• The heparin solution must be removed from each lumen prior
to treatment to prevent systemic heparinization of the patient.
Aspiration should be based on dialysis unit protocol.
