What are the procedure of paracentesis?

Paracentesis is a medical procedure that involves the insertion of a needle into the abdominal cavity to remove excess fluid for diagnostic or therapeutic purposes. The patient is typically positioned comfortably, and the skin is cleaned and sterilized. A local anesthetic may be administered to minimize discomfort, and a needle or catheter is carefully inserted into the abdominal cavity, guided by ultrasound if necessary, to withdraw the fluid. The collected fluid is then sent for analysis, and the site is bandaged after the procedure.
