What is the difference between transudative and exudative pleural effusion?

“Transudate” is fluid buildup caused by systemic conditions that alter the pressure in blood vessels, causing fluid to leave the vascular system. “Exudate” is fluid buildup caused by tissue leakage due to inflammation or local cellular damage.

What is the difference between pleural effusion and thoracentesis?

Thoracentesis is a procedure to remove fluid from the space between the lining of the outside of the lungs (pleura) and the wall of the chest. Normally, very little fluid is present in this space. An accumulation of excess fluid between the layers of the pleura is called a pleural effusion.

How do you confirm pleural effusion in thoracentesis?

Thoracentesis uses imaging guidance and a needle to help diagnose and treat pleural effusions. This is a condition in which the space between the lungs and the inside of the chest wall contains excess fluid. Thoracentesis helps determine the cause of the excess fluid.

What is transudative effusion?

Transudative pleural effusion is caused by fluid leaking into the pleural space. This is from increased pressure in the blood vessels or a low blood protein count. Heart failure is the most common cause.

What is the position for thoracentesis?

The ideal position for thoracentesis is for the patient to sit up at the edge of the bed leaning forward to rest arms and face on a table such that the back is accessible for the procedure (Figure 108–2). However, this may not be possible in many patients in the ICU due to mechanical ventilation or other reasons.

Which intercostal space is entered for a thoracentesis?

The recommended location for the needle insertion varies depending upon the source. Some sources recommend the mid-axillary line in the 6th, 7th, or 8th intercostal space. It is critical that the patient hold his or her breath to avoid piercing of the lung.

What is exudative effusion?

Exudative effusion is caused by blocked blood vessels or lymph vessels, inflammation, infection, lung injury, and tumors.
