Pulmonary Empyema

What is Pulmonary empyema?

Pulmonary empyema is a buildup of pus in the pleural space (space between the lung and chest wall).  It is a complication of bacterial pneumonia when the bacteria get into the pleural space and infect the tissue that lines the inside of the chest. Pulmonary empyema:

  • occurs infrequently and can happen to anyone
  • requires hospitalization for effective treatment

What are the signs and symptoms?

Symptoms of bacterial pneumonia include:

  • Fever
  • Weak cough
  • No interest in activity
  • Poor appetite

If empyema develops, symptoms become worse, and your child may have the following:

  • Very tired
  • Fever over 102°F
  • Shallow and rapid breathing

Sometimes the pus pushes on the healthy lung and it becomes hard to breathe. This can cause:

  • Shortness of breath with gasping
  • Pale or grey color
  • Difficulty walking
  • Chest pain with anxiety

How is pulmonary empyema diagnosed?

Tests to diagnose pulmonary empyema include:

  • Chest x-ray to confirm that an empyema is present and estimate the amount of pus in the chest
  • Ultrasound of the chest to determine the thickness and amount of pus
  • A computed tomography study (CT scan) may be done if there is any question about the diagnosis, but is usually not necessary
  • Blood tests to check for changes due to the empyema
  • A culture of the pus from the chest is the best way to identify the bacteria causing empyema

How is it treated?

  • Pain medicine is used to keep your child comfortable
  • Antibiotics are given for 14 days or more depending on the bacteria causing the infection
  • A chest tube (a small tube inserted between the ribs through the chest wall) is placed to drain the pus from the inside of the chest (see education sheet “Chest tube”)
  • The chest tube stays in place for 3 to 5 days
  • Oftentimes, medicine is given through the chest tube to help dissolve and drain the thick pus

In 10-20% of patients, surgery may be needed to help drain the pus. This surgery is called a VATs procedure (Video-Assisted Thoracoscopic surgery).  Several small incisions are made in the chest wall: one for a small video camera and others for instruments.  Pus and blood are removed from the chest. After the procedure the child returns to the hospital room with a chest tube in place to collect any remaining pus. This chest tube stays in place for 3 to 5 days. Pain medications are given to keep your child comfortable.

What else do I need to know?

  • Your child will be eligible for discharge after the chest tube is removed and he or she is able to drink fluids and take oral medications.
  • Children can easily lose 1 – 5 pounds during a complicated infection and nutrition is important to help with wound healing.
  • Remember, the lung is temporarily injured during pneumonia, but will heal with antibiotics and nutrition.
  • Pulmonary empyema is an uncommon complication of pneumonia and rarely recurs.
  • Children who experience pulmonary empyema are not vulnerable to subsequent lung infections.
  • Lung function studies performed months or years after pulmonary empyema reveal that children have remarkable healing ability.
  • Pulmonary empyema generally does not limit a child’s ability to participate in normal activity within one month of the event.
  • Additional antibiotics for 1 or more weeks may be required.
