WHILE YOU ARE HERE:
Before your procedure:
- Informed consent is a legal document that explains the tests, treatments, or procedures that you may need. Informed consent means you understand what will be done and can make decisions about what you want. You give your permission when you sign the consent form. You can have someone sign this form for you if you are not able to sign it. You have the right to understand your medical care in words you know. Before you sign the consent form, understand the risks and benefits of what will be done. Make sure all your questions are answered.
- Medicine may be given to help you relax. General anesthesia may also be given to keep you asleep and free from pain during the procedure. You may instead get local anesthesia to numb the procedure area. You may feel pressure or pushing during the procedure, but you should not feel pain.
During your procedure:
- The table may be tipped so that your head is slightly lower than your feet. Your healthcare provider will insert a needle through your skin until the needle reaches your vein. Ultrasound or x-ray may be used to help guide placement of the catheter. The catheter may be placed through your chest, neck, or arm.
- A guide wire will be used to help place the catheter in your vein. A catheter that contains or is coated with germ-killing medicine may be used to help prevent infection.
- The needle and guide wire will be removed, and the catheter will stay in the vein. Healthcare providers will secure the catheter to your skin with tape or stitches. A new bandage will be placed over the area to keep it clean and help prevent infection.
After your procedure:
Do not get out of bed until healthcare providers say it is okay. You will need to rest for a period of time. You may need to have a chest x-ray. The central line will be flushed with saline solution, heparin, or both. Saline and heparin are used to help keep the catheter open and clear. Heparin may help stop blood from clotting inside the catheter.
RISKS:
- The catheter may go into the wrong area or blood vessel during the procedure. Air or blood may get into the space around your lungs, causing heart or lung problems. You may get an infection where the catheter enters your body, or in your bloodstream. The catheter may break, bend, or move out of place, and not work. You may need to have the catheter replaced.
- Medicine may leak on your skin, causing swelling, pain and blisters. You 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. You may get a blood clot in the vein where your catheter was placed. This can cause pain and swelling, and it can stop blood from flowing where it needs to go in your body. The blood clot may break loose and travel to your lungs. This can be life-threatening.
