LINES AND PORTS
This page deals with the most commonly asked questions, but does not aim to replace the normal consultation process. You will have ample opportunity to discuss any further questions before your line is inserted.
Advantages of Semipermanent lines.
An ordinary drip placed in the arm will rapidly become infected and often blocks off, so that it can only be used for a short period of time before having to be replaced. Moreover, if irritant drugs such as those used in chemotherapy leak out of the drip, they can damage the skin and produce painful reactions. Semipermanent lines, as their name implies, can be left for many months with less risk of infection or damage to the patient's own tissue. Drugs and fluids can be given and blood samples taken reliably even in patients with poor veins.
Inserting the Line
Lines are either inserted on a day case basis or immediately before chemotherapy or other treatment is due to commence. It is essential that you have nothing to eat for 6 hours or drink for 2 hours before the time of the insertion, although you may take your normal tablets with a small sip of water. I urge you to have plenty to drink until then as dehydration is unpleasant and makes the operation considerably more difficult.
You should arrive at the hospital at least 2 hours before the time of the operation so that you are nicely relaxed while the line is being inserted.
The line is inserted in the operating theatre to minimise the risk of any infection. In the case of children, the line is inserted under general anaesthetic but in adults my normal practice is to insert the line under sedation. Most patients are totally unaware of the procedure but if you are at all unhappy about what is going on you will be able to tell me so that more sedation can be given. This technique is considerably safer than using a general anaesthetic and is well tolerated by all patients. Indeed, a minority of patients prefer not to have any sedation at all and this wish can be accommodated.
Local anaesthetic is used to insert the line. The vein is located with ultrasound to minimize the risk of damage to other blood vessels or the lungs, and the insertion process is repeatedly checked with an X-ray machine to ensure that the line is in exactly the right position. After the operation, you will return to your room and be given something to eat and drink. You will have a small incision 1 cm long, normally below your collar bone, as well as the tube coming out of your chest. If you have a port, there will be a small scar where the port is placed. There will be a dressing over each site.
If you stay in hospital for your chemotherapy, the nurses will teach you how to care for your line while using it in front of you. If you are to go home the same day, the nurses will briefly show you how to care for your line and you may leave hospital as soon as they are happy that this has been achieved. A friend or relative will have to take you home, and you should remain indoors for the rest of the day. Pain is minimal and patients rarely need more than a couple of paracetamol tablets for pain relief.
Please come back to the oncology outpatients' department or your chemotherapy unit a day or so after your line has been inserted so you can be shown how to look after it in more detail. If you have a port, please come back a week later so we can check the wound and flush the port. If you have chemotherapy planned, both can be done at the same time.
You will be given a copy of your Xray when you leave hospital. This must be taken with you to show the outpatient nurses the first time your system is used.
Living with your line
Semipermanent lines are designed to facilitate treatment and minimise disruption to your life. They are very easy to look after and quite painless. All patients with Groshong lines receive a patient booklet that is liberally illustrated and gives full instructions on how to care for your line when you leave the hospital. You will be given the telephone number of the oncology floor and your day unit, which you may telephone if you have any problems. You will be asked to return 10 days after the operation so that the stitches below your collarbone can be removed and the line examined. There will be some further stitches on the outside of the line, but these should not be removed except with my approval.
There are two important things to remember about caring for your line: firstly you must keep the line very clean and you must not touch it unless you have washed your hands thoroughly. Secondly, you must be very careful never to pull or tug on the line as it is possible to pull it out. Otherwise you may do all the things that you normally do. The wounds must be kept clean and dry for 10 days but after that you may shower. A bath carries a higher risk of infection, and although some patients do bathe and swim, please discuss this with your nurses.
If you have a port, you will need to keep the dressings dry for seven to ten days. After that you can shower or take a bath. The stitches dissolve and do not have to be removed, but the ends can be cut off by an oncology nurse after ten days. You cannot flush your port, but it should be flushed by your oncology unit every 3 to 4 weeks. Please click here for a sheet of instructions about your port
Complications and problems
Risks with these lines are very small in comparison with the considerable benefits that they bring. Difficulties associated with inserting the line are rare. The most common problems seen once the line is inserted are blockage and infection. Both these problems can be minimised by careful attention to cleanliness and efficient flushing of the line. If you are ever in doubt about your line, it is always advisable to give it an extra flush and to contact the hospital. I discourage other people flushing a patient's line simply because we have experienced blocked lines when such arrangements have failed. You will be given a sheet telling you when to flush your line (click here for a copy for adults or children), which can be as infrequent as once a week. Patients who really do not want to flush their own lines are best advised to have a port which will last for many weeks without flushing.
