paracenteses

Paracentesis is a medical procedure that involves the insertion of a needle or catheter into a body cavity to drain excess fluid. It is most commonly performed in the abdomen to remove ascites, which is the accumulation of fluid in the peritoneal cavity. Ascites can be caused by various conditions, including liver cirrhosis, heart failure, kidney disease, and certain types of cancer.

The procedure is typically performed under local anesthesia. After sterilizing the skin, the healthcare provider uses ultrasound guidance to identify the best location for insertion and to avoid puncturing any organs. A needle or catheter is then inserted into the peritoneal cavity, and the fluid is allowed to drain into a collection bag. The amount of fluid removed depends on the patient's condition and the reason for the procedure.

Paracentesis can provide symptomatic relief for patients experiencing discomfort due to abdominal distension, shortness of breath, and early satiety caused by ascites. It can also be used diagnostically to analyze the drained fluid for signs of infection, malignancy, or other abnormalities. While generally safe, potential complications include bleeding, infection, and leakage of fluid from the puncture site. The frequency of paracentesis depends on the underlying cause of the ascites and how quickly the fluid reaccumulates. In some cases, it may be a temporary measure, while in others, it may be a recurring necessity.
