Paracentesis
A trained physician will insert a special needle into the abdominal cavity giving the patient a local anesthetic around the injection site. The patient is seldom sedated for this procedure. Fluid is removed over a period of one to three hours depending on the individual. An IV may be started on the patient so that albumin may be given if the physician so orders.
In most cases, nothing to eat or drink for at least 6 hours prior to the procedure.
