This information will teach you about the placement and care of your central venous catheter (CVC).
There are many different types of catheters (thin, flexible tubes) and your doctor will decide which kind is best for you.
All devices have 1 central catheter that enters your body. On the outside, the catheter may divide into 1, 2, or 3 lumens (see Figure 1). Each lumen has a clamp, a needleless connector, and a disinfection cap on the end.
A CVC can be used to take blood samples, as well as give:
- Chemotherapy and other medications
- Blood transfusions
- Intravenous (IV) nutrition
The advantages of having a catheter are:
- You won’t need as many needle sticks.
- It can stay in your body for as long as a few years and be removed when it’s no longer needed.
Your nurse will teach you how to care for your catheter. You can have a caregiver, family member, or friend learn with you. You will learn how to use sterile technique to change your dressing. This will minimize your risk for infection. You will also learn how to change your needleless connectors and disinfection caps (SwabCaps®), as well as flush your catheter using a syringe with normal saline solution. You must flush your catheter to keep blood clots from forming inside of it. Once a week, you will change the needleless connectors, disinfection caps, and your dressing, as well as flush your catheter. You may want to mark your calendar to help you remember to do so. After you go home, use this information to help you remember the steps to care for your catheter.
Before Your Procedure
You may need to stop taking some of your medications before your procedure. Talk with your doctor about which medications are safe for you. We have included some common examples below.
- If you take medication to thin your blood, ask your doctor what to do. Some examples are aspirin, warfarin (Coumadin®), dalteparin (Fragmin®), heparin, tinzaparin (Innohep®), enoxaparin (Lovenox®), clopidogrel (Plavix®), cilostazol (Pletal®), prasugrel (Effient®), dabigatran (Pradaxa®), ribaroxaban (Xarelto®), apixaban (Eliquis®), and ticlopidine (Ticlid®). These medications can be used to treat blood clots or to prevent a heart attack or stroke.
- If you take insulin or other medications for diabetes, you may need to change the dose before your procedure. Ask the doctor who prescribes your diabetes medication what you should do the morning of your procedure.
- Please review the information in Common Medications Containing Aspirin and Other Nonsteroidal Anti-inflammatory Drugs (NSAIDs) for examples of what not to take and what to take instead.
- Don’t take vitamin E for 10 days before your procedure, or as directed by your doctor.
You must have someone 18 years or older take you home after your procedure. If you don’t have someone to do this, call one of the agencies below. They will send someone to go home with you. There’s usually a charge for this service, and you will need to provide transportation.

When you arrive at Memorial Hospital, take the M elevator to the 2nd floor. Enter through the glass doors and check in at the desk.
MSK Westchester is located at 500 Westchester Avenue, West Harrison, NY 10604.
When you enter the building, check in at the reception desk and they will direct you to Interventional Radiology.
Once you arrive, doctors, nurses, and other staff members will ask you to state and spell your name and date of birth many times. This is for your safety. People with the same or similar names may be having procedures on the same day.
Two areas of your body will be numbed. A small incision (surgical cut) will be made at the base of your neck. A second small incision will be made on your chest, under your collarbone. The catheter will be inserted through the second incision, tunneled under your skin to the first incision, and threaded into your vein.
The incision at the base of your neck will be stitched closed. The stitches will be absorbed and will not need to be removed. Your catheter will be stitched to your skin at the point where it exits your body (exit site) so that it will stay in place (see Figure 1).Back to top
After Your Procedure
You may have some discomfort at your incision sites and along the CVC tunnel. Ask your nurse for medication to relieve your pain.
Your dressings need to be kept dry following your procedure. Your nurse will change your dressings 24 to 48 hours after your procedure. He or she will teach you how to do this.
Two days after your procedure, you can remove the dressing that covers the small incision at the base of your neck. You don’t need to put a new dressing on this site. The strips of adhesive tape that cover this incision should be left in place until they start to peel off. This should happen about 3 to 5 days after your procedure.
Your catheter exit site will still need to be covered with a special dressing. This dressing prevents infection at this site. You will have stitches under your dressing. These stitches keep your catheter in place until the cuff on the catheter becomes anchored in the tunnel under your skin.
Your catheter will not interfere with your usual activities, such as household tasks, job responsibilities, and exercise. However, we suggest that you avoid contact sports, such as football and soccer, while your catheter is in place.
Prepare the following emergency kit and keep it with you at all times:
- 1 toothless clamp
- 1 dressing change kit
- Your doctor’s office and emergency telephone numbers
Changing Your Dressing, Needleless Connectors, and Disinfection Caps
- Don’t change your dressing, needleless connectors, or disinfection caps in the bathroom after a shower. The steam from a shower can create a moist environment under your dressing and affect the adhesive. Make sure you change your dressing, needleless connectors, and disinfection caps on a clean, flat surface.
- You will see the folded Map for Dressing Change: CVC included in the print version of this resource. Use it to follow the step-by-step instructions for changing your dressing. This is when you will use sterile technique. You will not be able to touch the booklet then because that would break sterile technique. Open the map and spread it out where you can see it.
- You will use a Tegaderm™ CHG dressing to cover your exit site unless your doctor or nurse gives you another dressing to use. Change your dressing once a week, as long as it stays dry, intact, and clean. Change it on the day you change your needleless connectors and disinfection caps and flush your catheter. You may need to change it more often if it becomes moist, soiled, or peels away from the skin.
- If the gel pad on your Tegaderm CHG dressing becomes swollen, change your dressing. You can test the gel pad by applying pressure to it with your index (pointer) finger. If you see an indent, the gel pad is swollen and your dressing should be changed. This can happen if there is a lot of sweat under your dressing.
- If you have problems with your skin, such as irritability or sensitivity, your nurse may suggest a different type of dressing. In that case, you may need to change it more often than once a week. No matter which dressing you are using, always change it right away if it starts to come off or gets wet. Don’t just put another dressing or more tape over it.
- 1 dressing change kit
- An alternative dressing, if supplied by your nurse
- 1 needleless connector for each catheter lumen
- 1 disinfection cap for each lumen
- Extra alcohol pads
- Nonsterile gloves
- Paper tape
- A mirror that can stand up on a table (a makeup mirror works well)
Sterile procedure for changing your dressing
- Prepare a clean area in which to work. Remember not to change your dressing in the bathroom after a shower.
- Gather your supplies. Wash your hands thoroughly with warm water and antibacterial soap or use hand sanitizer.
- Get into a comfortable position. Unpin the catheter from your clothing, if necessary. Open or remove your clothing to expose the catheter.
- Check to make sure the catheter clamp(s) is (are) closed.
- Open the Map for Dressing Change: CVC instructions included in the print version of this resource and spread it out where you can see it.
- Open and remove the outer plastic packaging of the dressing change kit. Two masks will be right on top (see Figure 2). Put the mask on. If someone is helping you with your dressing, they will also need to wear a mask. Don’t touch anything else inside the kit.
- Put on the nonsterile gloves. Remove the old dressing by gently grasping an edge of the dressing and slowly peeling it off your skin toward the exit site of the catheter. As you peel the dressing back, place your thumb or forefinger on top of the dressing over the catheter to prevent tugging on the catheter. To make it easier to remove, wipe the area underneath the dressing with an alcohol pad as you pull the dressing away from your skin. Make sure the entire gel pad comes off with the dressing. Throw away the gloves and old dressing.
- Without touching the area, inspect the exit site and the skin around it. It is easier to do this by looking in the mirror. Call your doctor or nurse after you complete the dressing change if you notice any signs of infection or irritation, such as:
- Red or raw skin
- Any drainage from the exit site
- Leakage around your catheter
- Unwrap your dressing change kit by pulling back on the corners of the outer wrapping in the following manner:
- Place the kit in front of you so that the top flap is facing you. Open the top flap away from you.
- Open the first side flap.
- Open the other side flap.
- Open the bottom flap towards you.
Open the package with the needleless connectors and drop them on your sterile field. If your nurse gave you an alternative dressing to use, drop them on the sterile field.
From this point on, don’t touch your catheter or your skin except with an alcohol pad. This will decrease your risk of getting an infection.
- Wash your hands thoroughly with warm water and antibacterial soap. Dry your hands thoroughly. Or you can use the hand sanitizer packet provided on the outside of the kit, as instructed by your nurse.
- Take the package with the sterile gloves out of the tray. Be careful not to touch anything else in the tray. Put on the sterile gloves following How to Put on Your Sterile Gloves, touching only the inside of the sterile glove with your bare hand. Be careful not to touch anything except what is in the dressing change tray after your gloves are on. Move everything from inside the dressing change tray onto the sterile drape.
- Open and remove all the alcohol prep pads from their wrappers. Put the alcohol pads back into the tray. Put the wrappers to the side or drop them in the trash.
- Pick up the ChloraPrep® applicator with your dominant hand. Pinch the wings on the side together until you hear a click (see Figure 3). This will make the antiseptic soak into the applicator sponge. You must press very hard to make the click sound.
- Using an alcohol pad, grasp the catheter with your nondominant hand, just above where it separates into lumens. (see Figure 4). Don’t touch the catheter itself. Touch only the alcohol pad. Hold the catheter away from your chest.
- Use your dominant hand to pick up the Chloraprep. Beginning at the exit site, scrub up and down and side to side with the Chloraprep to make a 2-inch box (see Figure 5). Discard the Chloraprep.
- Allow the site to dry completely. This may take at least 30 seconds. Don’t fan or blow on the site to speed up the drying. Hold the catheter away while it dries.
- While holding the catheter with your nondominant hand, take another alcohol pad in your dominant hand. Place it around the catheter at the incision site and gently, without tugging, clean down the catheter toward the area where it separates into lumens. Discard the alcohol swab in your dominant hand. Continue holding the catheter in your nondominant hand.
- Pick up a new alcohol pad with your dominant hand. Without tugging, clean down the lumen of the catheter (see Figure 6). Discard the alcohol pad. Repeat this step to clean each lumen. If the exit site is red, raw, swollen, or has drainage, notify your doctor after you finish the dressing change.
- Apply the No Sting Barrier Film to your skin in the shape of an open rectangle about the size of the Tegaderm CHG dressing. Allow it to dry completely. The No Sting Barrier Film will help the dressing stick to your skin. Discard the alcohol pad in your nondominant hand.
- Peel the backing off the Tegaderm CHG (see Figure 7). Center the gel pad over the exit site and smooth down the dressing edge. Don’t stretch the dressing when applying.
- Grasp the round paper tab on the outside and peel the plastic off all the way around the dressing (see Figure 8). Peel the notched tape off of the paper tab. Apply the tape under the tubing and over the dressing edge to secure the catheter. You may press the outside of the dressing to make sure it is intact.
You are now done with the sterile part of the dressing change. Keep your gloves and mask on to change the needleless connectors and disinfection caps.
- You will change the needleless connector and disinfection cap on each lumen of your catheter. Make sure you have 3 alcohol pads for each lumen.
- Check to make sure that the clamps on your lumens are closed before you change the needleless connectors and disinfection caps.
- Even though your gloves are on, they will no longer be sterile if you touched your skin when you put on your dressing, so don’t touch the inner part of the catheter tip or needleless connector. Using an alcohol pad, hold your catheter with your nondominant hand close to, but not touching, the needleless connector (see Figure 9).
- Using your dominant hand, scrub the connection site for 15 seconds with another alcohol pad and allow it to dry for 15 seconds. Twist off the old needleless connector. Throw away the old needleless connector and alcohol pad.
- Scrub the end of your catheter with a new alcohol pad for 15 seconds and allow it to dry for 15 seconds.
- Pick up the new needleless connector with your dominant hand. If there is a cover in place over the new needleless connector, remove it and then twist the new needleless connector onto your catheter (see Figure 10).
- If you won’t be flushing your catheter immediately, apply the disinfection cap to the end of the needleless connector.
- Repeat steps 22-27 for the second and third lumens.
- Remove your mask and sterile gloves. Throw them away.
Flushing Your Catheter
Flush the lumens with normal saline solution once a week, when your catheter is not in use. This is to keep the lines from becoming clogged. For more information, you can watch How to Flush Your Central Venous Catheter.
- 1 prefilled, 10 mL syringe containing normal saline solution. You will need 1 syringe for each lumen
- Nonsterile gloves
- Alcohol pads
- 1 disinfection cap for each lumen
- Gather your supplies.
- Wash your hands thoroughly with warm water and antibacterial soap. Dry them with a clean towel or a paper towel. Put on a pair of nonsterile gloves.
- To release the air bubbles in the syringe, gently tap the side of the syringe. Point the syringe up as you do this. Loosen but don’t remove the cap on the syringe. Press the plunger on the syringe until the air is pushed out. Retighten the cap.
- Pick up 1 lumen and unclamp it.
- If you have a disinfection cap, remove it.
- If you don’t have a disinfection cap, scrub the end of the needleless connector with an alcohol pad for 15 seconds and allow it to dry for 15 seconds.
- Remove the cap from the syringe. Throw away the cap. Make sure that nothing touches the clean end of the needleless connector while you are doing this.
- Carefully push the syringe into the needleless connector and twist it in a clockwise (to the right) direction until the connection feels secure. Try to inject the saline. If you can’t inject the saline, stop and check to be sure there are no twists or other blockages in the tubing. Try to inject the saline again. If you still can’t inject the saline, don’t use extra pressure to flush the line. Remove the syringe, reclamp your catheter, and call your doctor or nurse.
- Use the following push/pause method to flush your catheter:
- Quickly inject ? of the saline.
- Inject the last ? of the saline. After the injection, clamp your catheter.
- Untwist the syringe from the lumen and throw it away.
- Attach a disinfection cap to the end of the needleless connector.
- Repeat steps 3-11 for each lumen.
- Reclamp the lumens.
- Secure your catheter in a way that makes you feel comfortable. If you will pin your catheter to your clothing, prepare one 5-inch piece of paper tape. Fold down the edges of the tape (see Figure 11). Leave enough sticky tape so you can wrap it around all of the lumens. Avoid placing tape over the connection site. Leave the catheter hanging loose only if you are sure it will not be pulled.
- Throw away your mask and gloves and wash your hands thoroughly.
Caring for Your CVC
- Don’t submerge your catheter in water (such as in a bathtub or swimming pool).
- Clamp the lumens when your catheter is not in use.
- Keep your catheter secure at all times to avoid pulling it. You can tape the lumens of your catheter to your skin, tuck them into a bra if you wear one, or pin them to your clothing. Ask your nurse about the best way to secure your catheter. Avoid placing tape over the connection site.
- If your catheter is leaking at any time, clamp it above the leak. Use the white catheter clamp on the catheter, if possible. If the white clamp is not available, use the clamp found in the emergency kit. Wipe the area that is leaking with an alcohol pad. Cover the site with tape. Call your doctor or nurse immediately. Catheters can often be repaired.
While your catheter is in place, it is especially important to take good care of your skin to reduce your risk of infection. We recommend that you wash with Hibiclens® every day while your catheter is in place. It contains a fast-acting antiseptic called chlorhexidine gluconate (CHG) that kills germs that live on your skin and will reduce your risk of infection. Hibiclens can work for up to 6 hours after using it. You can purchase it from any local pharmacy or online. You will be sent home with a small bottle when you are discharged from the hospital. For more information, you can watch the video Showering While You Have a Central Venous Catheter.
Instructions for using Hibiclens
- If you are washing your hair, shampoo and rinse thoroughly.
- Wash your face with regular soap.
- Rinse your body with warm water from the neck down.
- Apply Hibiclens to a washcloth or directly to the skin being cleansed. Wash gently. Don’t dilute the Hibiclens.
- Rinse thoroughly with warm water and pat yourself dry.
Important points to remember when using Hibiclens
- Don’t use Hibiclens if you are allergic to chlorhexidine.
- Don’t use Hibiclens on your face, ears, genital region, or on deep wounds.
- Don’t use regular soap, lotion, powder, or deodorant after washing with Hibiclens.
You can shower with your catheter in place using a one-time-use waterproof cover that goes over your dressing. Each time you shower, cover the Tegaderm CHG dressing completely with a new waterproof cover to protect it from getting wet.
- To put on the waterproof cover, peel off the top and side strips. Place the top edge above your dressing. Smooth it down over your dressing. Do the same for the bottom part of your dressing, making sure that the bottom edge of the waterproof cover is below your dressing. Make sure the lumens of your catheter are tucked into the waterproof cover and completely covered.
- Don’t let the tape on the waterproof cover touch the Tegaderm CHG dressing. It can lift your dressing when you remove the waterproof cover after showering.
- Dry the waterproof cover before removing it.
- Don’t shower for longer than 15 minutes. Use warm water, not hot water. This will help prevent the waterproof cover from coming off.
- If your dressing gets wet, change it.
Call Your Doctor or Nurse Immediately if You:
- Have redness, swelling, or drainage around the area where the catheter exits your body
- Are unable to flush your catheter or if your needleless connector falls off
- Have a temperature of 100.4° F (38° C) or higher or chills
- Have a break or leak in your catheter
- Have an unexplained problem with your catheter
