Central Venous Catheter Placement

Your doctor will place this catheter in a large vein found in the patient’s neck, upper chest, leg,
or arm. These long, thin, hollow tubes are like the IVs placed in a patient’s arm except that they
are placed in a bigger vein. Central venous catheters (central lines) may be helpful if we are
having trouble finding good veins in the patient’s arms.

There are common reasons for having a central catheter. They include:
ξ To give large amounts of fluid or blood quickly.
ξ To measure how much fluid your body needs.
ξ To give medicines through the veins for a week or longer.
ξ To give medicines that can only be given through large central veins.
ξ To obtain frequent blood samples without needle sticks.
ξ To give special nutrition when foods or liquids can’t be given through the stomach or


As with any procedure, there are risks. Some of the risks include:
ξ Pain – Patients may feel a poke as the doctor inserts the needle. Numbing medicine is
used to lessen the pain. Once the needle is in, the pain is often mild and goes away.
ξ Collapsed lung – The lung is very close to veins in the neck and chest. When a central
catheter is placed in the chest area, if a needle passes through or misses the vein, the
needle could pierce the lung and cause it to collapse. If this happens, a chest tube will be
placed to re-inflate the lung. Rarely, a collapsed lung can result in death. This may
happen even if everything is done the right way.
ξ Infection – Any tube entering the body can make it easier for bacteria from the skin to
get into the bloodstream. Special care in cleaning the skin and applying the dressing at
the catheter site is done to decrease the risk of infection.
ξ Bleeding – When the doctor inserts the needle, there is a risk of nicking a blood vessel.
If this happens, the bleeding is often minor and stops on its own. Patients may notice a
bruise. Rarely, the chest can fill with blood which could be life-threatening.
ξ Clotting around the catheter – Blood clots can form in and around the catheter. If
inside, they can plug up the catheter so that we can no longer use it. These clots can
break off and travel through the bloodstream into the lungs. This could result in a serious
breathing problem (pulmonary embolism).
ξ Air in the catheter – Rarely, air enters the catheter while it is being placed. The air
bubbles may travel into the lungs causing severe breathing problems.
