- Create a skin incision with the scalpel along the path of the wire (approx. 0.5 cm).
- Perform serial dilation keeping one hand always holding the wire.
- Remember you just need to dilate the soft tissue; use your ultrasound to estimate how much soft tissue depth there is before you enter the vessel.
- Serial dilations with the smallest dilator (central line kit), medium then largest dilator (both from dialysis line kit), keeping sterile gauze over the site of dilation to minimize bleeding.
- With one hand on the wire always, slide the dialysis catheter over the wire up to the skin.
- Slowly bring the wire out through the catheter. Once the wire leaves the catheters purple port, hold onto the wire there then advance catheter fully into IJ vein past the skin.
- Note: In Trialysis = wire comes out the purple port. In Niagara = wire comes out the blue port.
- Remove wire. Once wire out, then clamp purple port.
- In Niagara = remove the wire and the blue stiffener in a single motion then clamp.
- Individually unclamp all ports + withdraw blood + flush with sterile saline, then re-clamp.
- Flush both red/blue ports with citrate and re-clamp.
- Each port is labelled with how much citrate is needed ie 1.5mL, 1.6mL.
- Apply central line caps to all ports.
- Suture line in place on both sides, cover with Tegaderm.
- Obtain CXR.
- Assess for pneumothorax + ensure roughly correct position of line.
- Document procedure.
