Paracentesis Offered at Mercy in Baltimore, Maryland

Paracentesis, also known as an abdominal tap, is used to remove excess fluid from the abdomen. It also can be used to remove a small sample of abdominal fluid for diagnosis. Excess abdominal fluid is often associated with cirrhosis and less commonly with heart failure, cancer and kidney disease.

Before paracentesis is performed, an area on the skin of the abdomen is cleaned and numbing medicine (lidocaine) is applied. During paracentesis, a needle is inserted into the abdomen with ultrasound guidance to extract fluid from the abdominal cavity. In people with cirrhosis, albumin is also given intravenously during the procedure to protect from kidney damage. The procedure is performed in our dedicated endoscopy suite. When performed as an outpatient procedure, patients typically go home the same day. 

Paracentesis can be recommended when there is a buildup of fluid in the abdomen causing discomfort, or when a physician needs a sample of abdominal fluid for diagnosis.
