Thoracentesis (say "thor-uh-sen-TEE-sis") is a procedure to remove fluid from the space between the lungs and the chest wall (pleural space). This procedure may also be called a "chest tap." It's normal to have a small amount of fluid in the pleural space. But too much fluid can build up because of problems such as infection or heart failure. The procedure may have been done to help with shortness of breath and pain caused by the fluid buildup. Or your child may have had this procedure so the doctor could test the fluid to find the cause of the buildup.
Your child's chest may be sore where the doctor put the needle or catheter into the skin (the puncture site). This usually gets better after a day or two. Your child can go back to his or her normal activities as soon as your child feels up to it.
If the doctor sent the fluid to a lab for testing, it may take several days to get the results. The doctor or nurse will discuss the results with you.
