    Aim

    To safely connect the patient to the haemodialysis circuit via the CVC using aseptic technique

    Patient preparation

    Position patient flat with head turned away from CVC

    Equipment

    • renal dressing pack
    • sterile gloves
    • povidine iodine solution
    • 2 x 10ml syringes
    • 2 x 3ml syringes
    • 1 x 20G needle
    • 10ml normal saline ampoule

    Procedure

    Prepare work surface

    1. Simple handwash
    2. Open Renal dressing pack

    9. Place sterile towel under clean catheter lumens and place paper towel on opposite side to create sterile field
    10. Remove cap from arterial lumen.  Place a 3ml syringe onto lumens.  Open clamp and aspirate the heparin lock. ie. 3mls. Close clamp. 
      Note:  Always keep the CVC under direct vision when the end is uncovered, only turn your back if the CVC tip is covered with a cap or syringe
    11. Flush arterial lumen, using 5mls normal saline, and ensure lumen will yield by flushing in and out two or three times
    12. Repeat 10 & 11 for venous lumen
    13. Take line with sterile gauze and clean it with Betadine before connecting it to the catheter. Release clamp on arterial lumen
    14. Repeat 13 for venous line
