When Your Child Has Pleural Effusion

The area between the chest wall and lung is called the pleural space. The lining around this space produces small amounts of fluid. This fluid helps lubricate the lining and allows the lungs to expand smoothly. Pleural effusion occurs when too much fluid builds up in the pleural space.

What Causes Pleural Effusion?Outline of child showing fluid trapped between compressed lung and body wall on right side. Healthy lung on left.

Pleural effusion can occur if your child has a lung inflammation or bacterial infection. It can also happen if fluid builds up after a surgery. If not treated, pleural effusion can lead to serious breathing problems. That’s why your child needs treatment right away.

What Are the Symptoms of Pleural Effusion?

Pleural effusion may not cause symptoms. If symptoms occur, they can include:

  • Shortness of breath or rapid breathing

  • Cough

  • Sharp chest pain that worsens with coughing or deep breaths

  • Fever of 100.4°F or higher

How Is Pleural Effusion Diagnosed?

Your child’s doctor listens with a stethoscope and taps on the chest. One or more of the following tests may be done to confirm the diagnosis:

  • X-rays in different positions to check whether fluid is free-flowing, which would indicate that infection is not present

  • Ultrasound or CT scan to view the amount and nature of fluid

  • Pleural fluid analysis, which involves inserting a needle into the pleural space to remove fluid and then sending it to a lab for testing

How Is Pleural Effusion Treated?

Treatment depends on how much fluid is present and whether or not it is infected.

  • If there is a small amount of fluid, it will likely go away on its own. Your doctor will have you watch your child at home. No hospital stay is needed.

  • If your child has a lot of fluid or pus, is having trouble breathing, or is uncomfortable, he or she may need to stay in the hospital. A chest tube will likely be placed to drain the fluid. 

  • If an infection is present, antibiotics will be given to treat it.

  • The doctor will identify and treat any other underlying problem.

What Are the Long-Term Concerns?

Often, the causes of pleural effusion in children are less serious than for adults. Your child should have no long-term effects once the underlying problem is treated. The doctor can tell you more about your child’s condition and what to expect.

After treatment, call the doctor right away if your otherwise healthy child has any of the following:

  • In an infant under 3 months old, a rectal temperature of 100.4°F (38.0°C) or higher

  • In a child 3 to 36 months, a rectal temperature of 102°F (39.0°C) or higher

  • In a child of any age who has a temperature of 103°F (39.4°C) or higher

  • A fever that lasts more than 24-hours in a child under 2 years old, or for 3 days in a child 2 years or older

  • A seizure caused by the fever

  • Increasing trouble breathing or rapid breathing

  • Coughing up blood

  • Worsening or continued chest pain
