PROCEDURES FOR HICKMAN CENTRAL LINES  

A Hickman catheter is a central venous line with a subcutaneous tunnel and has a cuff to hold it insitu.  It has the capacity to remain in place long term and be assessed only when required.

Hickman catheters are frequently used in patients with haematological conditions, or any medical condition when long term venous access is required.

The catheter can be used for the following:  

Taking of blood samples for laboratory analysis.
Administration of intravenous fluids, medications and chemotherapy.
Administration of blood products.
Administration of parental nutrition. 

When not in active use the catheter is kept patent by flushing and a heparinised saline ‘lock’ which prevents clot formation.  This procedure may be performed by Registered Nurse who has attended the Intravenous Study Day (part 2) and has been deemed competent. 

There are five major procedures for the care of a Hickman catheter:

1.       Twice weekly flushing to maintain patency.

2.  Taking blood samples for laboratory analysis. 

3.       Connection and disconnection for IV access. 

4.       Exit site dressing. 

5.       Observing for rigors and symptoms of infection.
