How is pleural tapping done?

How is pleural tapping done?

Thoracentesis (pleural tap) is a procedure to remove excess fluid from the space between the lungs and the chest wall. This space is called the pleural space. The procedure is done with a needle or a plastic catheter that is inserted through the chest wall.

What are indications for pleural tapping?

Indications. Diagnostic tap: unilateral pleural effusion. bilateral pleural effusions where aetiology unclear (not a presumed simple transudate from common causes)

Is thoracentesis and pleural tapping same?

Thoracentesis, also known as a pleural tap, is a procedure performed to remove excess fluid or air from your pleural space. The pleural space is the small space between your lungs and your chest wall. A buildup of fluid in your pleural space is called pleural effusion.

Which needle is used for pleural tapping?

Using a 25-gauge needle, place a wheal of local anesthetic over the insertion point. Switch to a larger (20- or 22-gauge) needle and inject anesthetic progressively deeper until reaching the parietal pleura, which should be infiltrated the most because it is very sensitive.

What position is used for thoracentesis?

You will be in a sitting position in a hospital bed. Your arms will be resting on an over-bed table. This position helps to spread out the spaces between the ribs, where the needle is inserted. If you are not able to sit, you may lie on your side on the edge of the bed.

At what level is pleural tapping done?

In order to minimize potential injury of the diaphragm, the lowest recommended level for thoracentesis is between the eighth and ninth ribs (eighth intercostals space). Mark the area of needle insertion by pressing a pen or pen cap firmly on the skin creating an indentation that will remain after the ink is washed off.

Which is the preferred site for doing a pleural tap and why?

Defining the correct site: Mark the optimal site for aspiration, on the posterolateral aspect of the chest wall (midscapular or posterior axillary line), 1–2 intercostal spaces below the percussed upper border of the effusion.

What size needle is used for a thoracentesis?

It is generally recommended that needle size be limited to 18-gauge or smaller to minimize risk of pneumothorax and damage to nearby structures. US-guided thoracentesis is associated with a significantly lower rate of complications and has become the standard of care.

Which rib is thoracentesis?

Be sure to insert the thoracentesis needle just above the upper edge of the rib and not below the rib, to avoid the intercostal blood vessels and nerves at the lower edge of each rib.

How much fluid is removed during thoracentesis?

Traditional guidelines recommend that the volume of fluid removed during a thoracentesis should be limited to <1.5 liters, to avoid re-expansion pulmonary edema.

Where can I do pleural tap?

Is pleural tapping painful?

You may feel a pinch and stinging when your doctor injects local anesthetic into you back. You may feel pressure or discomfort when the needle is inserted into your back. You may also have chest pain and an urge to cough when your doctor withdraws the pleural fluid in your chest. These sensations should be brief.

What medicine removes fluid from lungs?


  • Diuretics. Diuretics, such as furosemide (Lasix), decrease the pressure caused by excess fluid in the heart and lungs.
  • Blood pressure drugs. These help manage high or low blood pressure, which can occur with pulmonary edema.
  • Inotropes.
  • Morphine (MS Contin, Infumorph, others).

What color is pleural fluid?

Normally, this area contains about 20 milliliters of clear or yellow fluid. If there’s excess fluid in this area, it can cause symptoms such as shortness of breath and coughing. An excess of pleural fluid, known as pleural effusion, will show up on a chest X-ray, CT scan, or ultrasound.
