| What stops the central line falling out?
There is a small 'cuff' around the central line which can be felt under the skin just above the exit site. The tissue under the skin grows around this cuff over a period of about three weeks and holds the line safely in place. Until this has happened you will have a stitchholding the line in place.
Care of your central lineWhen the central line is not being used there is a small risk that it may become blocked. To stop this happening a small amount of fluid is 'flushed' into the line using a syringe. This is usually done once a week. The exit site will also need to be cleaned once a week to reduce the risk of infection. If you have a dressing on the site it will need to be changed once a week.The nurses at the hospital may teach you how to do this for yourself if you feel able to, or a district nurse can do it for you at home.Possible problems
Infection It is possible for an infection to develop either inside the central line or around the exit site. You should contact your hospital doctor or nurse if:the exit site becomes red or swollen or painfulyou notice discoloured fluid coming from ityou develop a temperature.You will be given antibiotics but if these do not clear the infection from the line, it may have to be removed.Clots It is possible for a blood clot (thrombosis) to form in your vein at the tip of the line. You may be given a tablet of warfarin (an anticoagulant) to take each day to help prevent this. If a clot does form the line may have to be removed. You will also be given some medication to dissolve the clot.Signs of this are:Air in the central line No air must be allowed to get into your central line. The clamps should always be closed when the line is not in use. The line must not be left unclamped when the caps are not in place.Break or cut in the line It is important that you do not get a break or cut in the line. Do not use scissors near the line and only use the clamp on the thicker, strengthened part of the line.If the line does get cut or split, try to clamp it between the split and the exit site (where it comes out of your ****) and call your hospital. The nurses may be able to repair the line, but if this can't be done, the line will be removed.how the central line is removedWhen you no longer need the central line it will be taken out. A doctor or nurse will do this for you, usually in the outpatients department. You will not need to have a general anaesthetic when the central line (catheter) is removed.
You will be asked to lie flat on a bed. Your chest will be cleaned with antiseptic, and the line will be gently but firmly pulled until it loosens and comes free. This does not usually take more than a few minutes, but can be uncomfortable.If the line has been there a long time, the nurse or doctor may need to do a minor procedure to remove it. A dressing will be put over the exit site and you will be asked to remain lying down until it is certain that there is no bleeding
