Please see the Annals of B Pod article on central line placement in order to review indications for this procedure and how to select an appropriate catheter.


Preparation

  • Assess the anatomy of the selected insertion site and evaluate it using ultrasound prior to starting procedure.
  • Identify necessary PPE- wash hands, wear cap, mask, sterile gown, and sterile gloves.  Use sterile probe cover for the ultrasound.
  • Clean the insertion site with chlorhexidine.
  • Place a full drape on the patient.
  • Maintain sterile field throughout the procedure.
  • Prepare equipment including flushing lines and placing caps on the ports.

Catheter Insertion

  • Identify the needle insertion site that will allow cannulation of the desired vein.
  • Anesthetize the area over the insertion site.
  • Insert and advance the needle while continuously aspirating.
  • Follow the needle tip into the vessel using ultrasound guidance.
 
  • Successfully cannulate the vessel and ensure free return of dark red, non-pulsatile blood.
  • Stabilize the needle while disconnecting the syringe.
 
  • Insert guidewire through the needle to a depth of 20-30 cm.
  • Remove needle while maintaining control of the guidewire.
  • Confirm guidewire is in the vessel using ultrasound.
 
  • Make small skin incision adjacent to the guidewire.
  • Advance dilator over the guidewire and into skin with a twisting motion while maintaining control of the guidewire.
 
  • Ensure the guidewire moves freely within the dilator, then remove dilator.
 
  • Advance catheter over the guidewire and into the vessel to the appropriate depth for the selected insertion site.
  • Remove guidewire and keep the brown port covered to prevent air entry until a cap can be placed on the brown port.
  • Aspirate and flush each lumen.

Securing the Line

  • Suture the line in place at the blue/white clips and the triangular holder.
  • Add biopatch and place a sterile dressing.
  • Obtain CXR following the procedure.
