Edema marked by excess serous fluid in the peritoneal cavity. Synonym: hydroperitoneum; hydrops abdominis; See: edema; peritonitis; illustrationascitic (-sit'ik), adjective


Ascites may be caused by interference in venous return of the heart (as in congestive heart failure), obstruction of flow in the vena cava or portal vein, obstruction in lymphatic drainage, disturbances in electrolyte balance (as in sodium retention), depletion of plasma proteins, cirrhosis, malignancies (such as ovarian cancer), or infections within the peritoneum.

Patient care

Ventilatory effort, appetite and food intake, fluid intake and output, and weight are assessed. The patient should be advised to limit fluid intake to about 1.5L daily and be educated about a low-sodium diet. Both of these interventions may limit or slow the reaccumulation of fluid in the peritoneum. Abdominal girth is measured at the largest point, and the site marked for future measurements. Paracentesis, if necessary, is explained to the patient. Emotional and physical support are provided to the patient throughout the procedure. Desired outcomes include eased ventilatory effort, improved appetite, improved general comfort, and identification of the cause of the accumulated fluid.

ascites chylosus

Chyle in the ascitic fluid, usually due to rupture of the thoracic duct.

diuretic-resistant ascites

Ascites in the peritoneal cavity that cannot be eliminated with diuretic medications such as furosemide and spironolactone. It must be managed with high-volume paracentesis or a transjugular intrahepatic portosystemic shunt).
