HOW CAN WE HELP YOU? Call 1-800-TRY-CHOP
Abdominal drainage is a procedure to drain fluid from the peritoneal cavity, the space between the abdominal wall and organs. Inflammation, infection and traumatic injury, among other things, can cause fluid to build up in the cavity. The fluid is called ascites.
First we will perform an ultrasound or CT scan on your child to evaluate the amount and location of the fluid. Then the doctor will inject a local numbing medicine at the site where the fluid will be drained.
The doctor will guide a small needle through the skin and into the fluid, and the fluid will be sucked out (aspirated) with a syringe. If it is likely that fluid will continue to accumulate, the doctor will place a drainage catheter, using live X-ray (fluoroscopy) for guidance. Your child will be protected by an X-ray shield.
A small amount of the ascites (the fluid) will be sent to the laboratory to determine what caused the accumulation.
Younger children are usually given IV sedation so they aren’t awake during the procedure. If your child is older or has medical problems that prevent us from giving IV sedation, we will use only local numbing medicine.
Approximately 30 to 60 minutes.
The procedure is considered low risk. However, potential complications include:
Some children feel pain or discomfort at the needle insertion site, usually in the first day or two after the procedure. You may give your child over-the-counter pain medication.
We will place a bandage over the site. If your child doesn’t have a drainage catheter, keep the bandage dry and in place for 48 hours. Then you may remove the clear bandage and the gauze and your child can shower or take a bath as usual.
If a drainage catheter was placed, the clear bandage and gauze must remain dry and in place until the catheter is removed. In addition, the catheter will be secured with a locking device (StatLock®) which must not be removed. You may sponge-bathe your child, as long as you keep the site dry.
If a drainage catheter was inserted, your child will need to avoid activities, such as rough playing or contact sports, which may result in a pull to the catheter. Children who don’t have a drainage catheter may resume normal activity in one or two days.
