Tunneled Central Lines In Children


A tunneled central line is a type of IV catheter. A catheter is a flexible tube used to give treatments and to take blood. A tunneled central line is a catheter that you can see under your child's skin before it enters a large vein near his heart. A tunneled central line can stay in for several months.


The night before the procedure:

  • Your child may need blood tests before the procedure. Write down the date, time, and location for each test.
  • Ask healthcare providers about directions for eating and drinking.

The day of the procedure:

  • Write down the correct date, time, and location of your child's procedure.
  • Tell healthcare providers if your child is allergic to latex or has any other allergies.
  • Ask your child's healthcare provider before you give your child any medicine or food on the day of the procedure. Bring a list of your child's medicines or the medicine bottles when you take him to see his healthcare provider. Tell healthcare providers if your child takes herbs, food supplements, or over-the-counter medicine.
  • You or a close family member will be asked to sign a legal document called a consent form. It gives healthcare providers permission to do the procedure or surgery on your child. It also explains the problems that may happen, and your choices. Make sure all your questions are answered before you sign this form.


  • Ultrasound and x-ray may be used to help guide placement of the catheter. Local anesthesia medicine will be used to numb the area where the catheter will be inserted. Your child may get general anesthesia to make him sleep.
  • The healthcare provider will insert a needle through your child's skin until the needle reaches the vein. A guide wire is used to help place the catheter in the vein. A catheter that contains or is coated with germ-killing medicine may be used to help prevent infection.
  • The needle and guidewire will be removed, and the catheter left in the vein. Healthcare providers secure the catheter to your child's skin with tape or stitches. A bandage is placed over the area to keep it clean and help prevent infection. An x-ray will be done to check the catheter's location.


  • Your child gets sick with a cold or flu, or he has a fever.
  • You cannot get your child to his procedure on time.


  • Your child may bleed more than expected, or the catheter may go into the wrong area or blood vessel during the procedure. Air or blood may get into the pleural (lung) cavity in the chest and cause heart or lung problems. Your child may get an infection where the catheter enters his body, or the infection may be in his bloodstream. The catheter may break, bend, or move out of place and not work. It may need to be taken out, and a new catheter put in. The catheter may go into the wrong area or blood vessel during the procedure. Air or blood may leak into the space around your child's lungs and cause heart or lung problems. The area around your child's catheter may get infected, or he may get an infection in your bloodstream. Your child's catheter may get blocked, and healthcare providers may need to remove or replace it.
  • Medicine may leak on your child's skin, causing swelling, pain, or blisters. Your child can have bleeding, an allergy to heparin, or heparin-induced thrombocytopenia (HIT). HIT is a low number of blood platelets, which increases the risk of bleeding. Your child may get a blood clot in the vein where the catheter is placed. This can cause pain and swelling, and it can stop blood from flowing where it needs to go in his body. The blood clot may break loose and travel to the lungs. A blood clot in the lungs can cause chest pain and trouble breathing. This problem can be life-threatening.
  • If your child does not have a central line placed, he may need to get multiple needle sticks. It may be hard for your child's healthcare providers to give him the treatment he needs. Contact your child's healthcare provider if you have questions about the risks of a tunneled central line.
