A thoracentesis is an operative surgical procedure to " to remove fluid from the space between the lining of the outside of the lungs (pleura) and the wall of the chest."[1][2]

Procedure

Routine ultrasonography can help obtain fluid samples and reduce complications according to randomized controlled trials.[3][4][5]

The amount of fluid sent for cytology should be at least 60 mL if only direct smear/cytospin is used; whereas 150 mL should be sent if both direct smear/cytospin and cell block preparations are used.[6]

Although a catheter is recommended by some expertsref name="pmid17035643">Thomsen TW, DeLaPena J, Setnik GS (October 2006). "Videos in clinical medicine. Thoracentesis". N. Engl. J. Med. 355 (15): e16. DOI:10.1056/NEJMvcm053812. PMID 17035643. Research Blogging. </ref>, it does not clearly reduce the rate of pneumothorax.[5]

Complications

The rote of pneumothorax is about 6%.[7]
