Wikipedia Meaning and Definition on 'Paracentesis'
Paracentesis is a medical procedure involving needle drainage of fluid from a body cavity, most commonly the peritoneal cavity in the abdomen.
A related procedure is thoracocentesis, which is needle drainage of the chest cavity. Pericardiocentesis involves taking fluid in the area of the pericardium.
It is used for a number of reasons:
The procedure is often done in a doctor's office or an outpatient clinic. In an expert's hands, it is very safe, although there is a very small risk of introducing an infection, causing excessive bleeding or perforating a loop of bowel. Some of these risks can be minimized greatly with the use of ultrasound guidance.[See more about Paracentesis at Dictionary 3.0 Encyclopedia]
