Procedure
Ultrasound is used to determine the appropriate site for the ascites puncture. After disinfection of the skin and local anesthesia of the skin and abdominal wall, a needle is inserted into the ascites until the fluid can be aspirated. The stitch only lasts a few seconds. We may also inject a sleeping pill into your vein. In the case of a therapeutic puncture, a cannula is left in the fluid collection through which the ascites can drain over the next few hours. After the needle or cannula has been withdrawn, a plaster is applied to the puncture site and the intervention is complete. In rare cases, a small tube is inserted into the abdominal wall, which can remain permanently implanted (PleurX); this will be discussed with you separately in advance.
Preparation
Apart from determining the blood coagulation parameters, no special preparations are necessary before an ascites puncture. The procedure sometimes requires an infusion in your arm, which will be given to you before the procedure.
Aftercare
Once the procedure is complete, you may return home or to the ward. In the case of large-volume (> two liters) therapeutic punctures, an albumin infusion is administered as a protein/fluid substitute. If you feel dizzy or have circulatory problems, sit down and drink something. If the symptoms do not improve, contact your doctor or otherwise go to an emergency ward. If you have been given a sleeping pill during the procedure, you are not allowed to drive on the same day, so do not come with your own vehicle and ask to be picked up.
