This leaflet has been produced to give you general information about your procedure. Most of your questions should be answered by this leaflet. It is not intended to replace the discussion between you and the healthcare team, but may act as a starting point for discussion. If after reading it you have any concerns or require further explanation, please discuss this with a member of the healthcare team.
What is a skin tunnelled line?
A skin tunnelled line is a long, hollow tube inserted into one of the veins in the neck or under the collar bone. You might hear it referred to as a ‘line’, ‘skin tunnelled line’ or ‘Hickman’. It has openings on both ends and the space inside the line is called a lumen. A line can have one or two lumens. The lumens can be found at one end of the line, while the other end which is the tip will sit in a large vein located just outside your heart. The lumens have clamps and bungs on them which will remain closed when not in use. The line is held in place by a small ‘cuff’ around the central line which can be felt under the skin near the exit site (where the line comes out of your body). This information leaflet will explain why you need a line, what to do before you come in for the procedure and how to care for it when you are at home.
Why do I need a skin tunnelled line?
A skin tunnelled line allows you to receive Parenteral Nutrition (PN) or Intravenous Fluids (IVF) that could cause irritation to your veins in your arms.
Can there be any complications or risks?
Serious problems are extremely rare while a skin tunnelled line is being placed. However as with most procedures, there are some risks involved. The doctor placing your skin tunnelled line will explain these to you.
How do I prepare for the skin tunnelled line?
Most skin tunnelled lines are put in as a ‘day case’ procedure (this means that you will not have to stay in hospital overnight). Your doctor/nurse will tell you what time you should come into hospital to have your line inserted if you are not already an in patient.
Some patients may prefer to have some sedation during the line insertion. This involves giving you a sedative through a cannula which can make you feel relaxed. This medication will not make you sleep during the insertion but will help reduce any anxiety you may be feeling.
A member of your hospital team will talk to you about whether intravenous sedation is a suitable option for you.
What will happen?
The skin tunnelled line is inserted by a specially trained doctor. A local anesthetic is administered to numb the area where the line enters the body. You may be given sedation to help you relax during the procedure. A small opening is made on the skin near to the collarbone or neck to help find the correct vein. This is called the insertion site. The exit site is where the line comes out of the chest. After the line has been put in you will have a chest X-ray to make sure it is in the right place. You will have stitches on the skin, holding the line in place. Insertion site sutures to be removed 7 days post insertion and exit site sutures to be removed 21 days post insertion. The site will be covered by a clear dressing. This will be changed once a week.
Should I feel pain?
You may have some bruising and be a little sore for a few days. Some patients take mild pain relief medication to ease this (make sure you follow the instructions on the packet). Once the bruising has gone the skin tunnelled line should be painless.
What will happen after the procedure?
The local anaesthetic will wear off after you have returned to the day unit or ward. It is normal to feel some discomfort and you will be given pain relief medication to ease this. There may also be some blood on the dressing and bruising. This is all normal. The dressings will be changed after a 24 hours.
Who will care for my skin tunnelled line?
While in hospital your skin tunnelled line will be looked after by nursing staff. This involves:
- Cleaning the exit site and applying a new dressing at least once a week.
- Flushing the line every week to prevent blockages when it is not being used.
- Checking the skin tunnelled line and the area it enters your chest every day for problems with the tubing or exit site.
Before you leave hospital you will be shown how to care for your line, you will go through a training package with your nutrition nurse. If you are unable to care for the line, the nutrition nurses will arrange for your homecare registered nurse to look after your line. If you have any problems at home, please contact us using the numbers at the end of this leaflet.
Caring of your skin tunnelled line at home
Use a transparent dressing to cover the line. This will ensure the exit site is kept dry during a shower.
Having a bath
Bathwater is not as clean as shower water so if you have a bath please make sure to keep the exit site and the end of the line out of the water. The line must not be placed under water.
Sports like tennis, golf or strenuous gym exercises should be avoided. There is a risk your skin tunnelled line could become dislodged due to a lot of upper body movement. Swimming is not advised with a tunnel line as you are not be able to keep the exit site or end of line out of water. This could increase the risk of infection. Your doctor/ nutrition nurse can advise you about other sports which are acceptable.
To prevent infection your skin tunnelled line must be kept clean and dry. The dressing should be changed once weekly or more frequently if the dressing becomes soiled, loose or wet.
Keeping the skin tunnelled line working
If your skin tunnelled line is not always being used, the plastic clamp must stay closed. Remember to check it is closed every day and that the needle free device on the end is securely attached. Flushing your line before and after each infusion will help to prevent it becoming blocked. We recommend your line is flushed once a week with normal saline. You will be trained how to complete this or if you are unable to care for your line the homecare team will complete this for you. The needle free device at the end of your line should be changed at the same time (weekly).
You should contact your specialist nurse Monday to Friday between 7:00am – 4:00pm or Ward 11 at Castle Hill Hospital after 4 pm and at weekends for any of the possible problems listed below.
It is possible for an infection to develop inside the line or in the area where it goes into the vein. If you develop a temperature 38 degrees or higher, notice any swelling, or redness, along the vein above the insertion site contact your specialist nurse or home care team.
Leaking of Parenteral Nutrition (PN), Blood or Fluid:
If you notice any leaking from the line it may be a hole that has developed in the line. Contact your specialist nurse or home care team.
Line Blocked/infusion stops:
Your infusion of parenteral nutrition (PN) or Intravenous Fluid (IVF) will not flow through the line, or you are unable to flush using normal pressure.
Report any difficulties flushing your line to your specialist nurse who may need to arrange admission to hospital to ensure you continue to receive your home prescription to prevent dehydration. In this instance you may be required to have a cannula inserted for the administration of peripheral fluids or peripheral parenteral nutrition.
The line breaks or you accidentally cut the line:
You notice a cut or tear in the line. Contact your specialist nurse or homecare team who will arrange a repair or replacement of your tunnelled line.
Air in the Tunnelled line entering the bloodstream:
You may suddenly have difficulty breathing, experience chest pain, dizziness or confusion. Stop the infusion and immediately clamp the catheter.
Contact the emergency services
If possible lie down with your head lower than your hips and feet until assistance arrives.
