In most cases, you will lie on your back. In some instances, you may need to be in a different position. The area where the needle will be inserted is cleaned with a solution and draped with sterile cloths. An injection of a local anesthetic will be given to numb the area. A needle will be carefully inserted into the abdomen. The fluid will be removed using a syringe.
The amount of fluid removed depends on your condition. If it is being done to make a diagnosis, the doctor will remove a small amount of fluid and send it for testing. If the procedure is being done to make you feel better, more fluid may be removed.
About 10-15 minutes, depending on how much fluid needs to be removed
There will be some stinging or burning while the anesthesia is injected. After the area is numb, you will not feel pain.
You will stay in the recovery room for a few hours. Your blood pressure and other vital signs will be monitored. If you have a lot of fluid leakage or are having trouble breathing, you may need to stay in the care center.
Follow special instructions on caring for the needle insertion site and watching for signs of infection.
