How It Is Done continued...
The needle site between your ribs will be
cleaned with an antiseptic solution. Your doctor will give you a
local anesthetic in your chest wall so you won't feel
any pain when the longer needle that withdraws the fluid is inserted. Once the
area is numb, your doctor will insert the needle to where the fluid has
collected (pleural space). You may feel some mild pain or pressure as the
needle enters the pleural space.
A syringe or a small tube
attached to a vacuum bottle is used to remove the pleural fluid. Your doctor
will collect fluid to send to the lab. Once the fluid
is removed, the needle or small tube is removed and a bandage is put on the
procedure takes about 10 to 15 minutes.
After the test
An X-ray may be taken right after the procedure to make
sure that no complications have occurred.
If more pleural fluid collects and
needs to be removed, another thoracentesis may be done later.
How It Feels
When you are given the shot to numb your
skin at the needle site, you will feel a sharp stinging or burning sensation
that lasts a few seconds. When the needle is inserted into the chest wall, you
may again feel a sharp pain for a few seconds.
When the pleural
fluid is removed, you may feel a sense of "pulling" or pressure in your chest.
Tell your doctor or nurse if you feel faint or if you have any shortness of
breath, chest pain, or uncontrollable cough.
If a large amount of
pleural fluid was removed during the procedure, you will probably be able to
breathe more easily.
Thoracentesis is generally a safe procedure. A
chest X-ray may be done right after the procedure to make sure that no
complications have occurred. Complications may include:
- A partial collapse of the lung (pneumothorax). This may occur if the needle used to
remove the pleural fluid punctures the lung, allowing air to flow into the
- Pulmonary edema, which may occur if a
large amount of fluid is removed.
- Infection and
- Damage to the liver or spleen, though this is
