Ascites Tap (Paracentesis)
About the procedure
Ascites tap, also called paracentesis, is a procedure to remove excess fluid from the abdominal cavity (ascites). It helps relieve discomfort, swelling, and breathing difficulties, and allows laboratory analysis of the fluid to identify infections, cancer, or liver/kidney disorders. The procedure is usually done under sterile conditions in a hospital or clinic, sometimes guided by ultrasound.
Care before the procedure
- Empty your bladder before the procedure if instructed.
- Inform your doctor about blood thinners or bleeding disorders.
- Fast for a few hours if advised by your physician.
- Arrange someone to accompany you if sedation is planned.
Care during the procedure
- You will lie on your back or slightly tilted.
- The abdomen is cleaned and draped with sterile sheets.
- Local anesthesia is applied to numb the area.
- A thin needle or catheter is inserted to drain fluid, sometimes guided by ultrasound.
- Fluid may be collected for lab testing while excess fluid is removed to relieve pressure.
Care after the procedure
- Apply pressure and a sterile dressing at the puncture site.
- Rest and avoid heavy lifting for 24 hours.
- Monitor for bleeding, infection, or worsening abdominal pain.
- Report fever, persistent pain, swelling, or redness at the site.
- Follow-up may include blood tests or repeat imaging to assess fluid reaccumulation.
Eligibility
- Patients with painful or tense abdominal swelling due to fluid accumulation.
- Liver disease patients with ascites (e.g., cirrhosis).
- Suspected infection in the abdominal fluid (spontaneous bacterial peritonitis).
- Cancer-related ascites to diagnose or relieve symptoms.
- Kidney disease or heart failure causing fluid buildup in the abdomen.
