Ascites puncture (Paracentesis)

Paracentesis (abdominal puncture) is a procedure that allows the evacuation of contents from the abdominal cavity (peritoneal cavity). Ascites occur due to the accumulation of fluid in the abdominal cavity as a result of infection, inflammation, injuries or diseases such as cirrhosis or cancer. The liquid is evacuated by means of a long, thin needle that is introduced into the abdominal cavity. When intervention is done for diagnostic purposes, the fluid is sent to the laboratory for analysis. Evacuation of the fluid for therapeutic purposes reduces the pressure or pain. The procedure lasts 20-30 minutes.


• In order to detect the cause of fluid accumulation in the abdominal cavity.

• For the purpose of detecting an infection, a malignant tumor, or injuring one of the abdominal organs.

• In order to remove excess fluid from the abdominal cavity.


• During intervention, the patient is in a lying position. The puncture site is determined by physical examination or ultrasound of the abdomen. The puncture field is disinfected and then the content (ascites) is punctured with special needles or a disposable set. During this procedure you can feel pain or pressure.

• If paracentesis is done for diagnostic purposes, the content is sent to biochemical, microbiological and cytological analysis. When it comes to therapeutic paracentesis it is possible to evacuate up to 4-5 liters of liquid. If a large amount of fluid is removed, the vein (intravenous) will be compensated for liquid.

• When the procedure is completed, a bandage is placed over the puncture point. The next hour is followed by tracking pulse, blood pressure and temperature.


• Very rarely there is infection, damage to the hollow organs of the abdominal cavity and bleeding.

• If a large amount of fluid is removed, there is a risk of falling blood pressure.


• You need to completely empty the bladder.

• Tell your doctor about all the medicines you take in regular therapy. Tell your doctor if you have an allergy to medicines and food.

• If you are taking medicines that prevent blood clotting (Aspirin, Plavix, Clopidix, Farin, Sincum, Sintra, Pradaxa, Xarelto, Eliquis, Fraxiparin), consult your doctor about correcting the dose of the medicine before the procedure.

• If you are pregnant or suspected of pregnancy, report to your doctor.


• If a large amount of liquid has been evacuated, it may happen that a clear liquid is emitted from the punctate site after a day or two.

• It is necessary to contact the Tesla Medical team immediately if you have a temperature above 38 ° C, severe stomach pain, puncture site redness, urinary blood or bleeding from the puncture site.
