Chronic lung disease (CLD) is a general term for long-term respiratory problems in premature babies. It is also known as bronchopulmonary dysplasia (BPD).
CLD results from lung injury to newborns who must use a mechanical ventilator and extra oxygen for breathing. The lungs of premature babies are fragile and are easily damaged. With injury, the tissues inside the lungs become inflamed and can break down causing scarring. This scarring can result in difficulty breathing and increased oxygen needs. Some of the causes of lung injury include the following:
Chronic lung disease can develop in premature babies who have had mechanical ventilation (breathing machine). Risk factors for developing CLD include:
The following are the most common symptoms of CLD. However, each baby may experience different symptoms of the condition. Symptoms may include:
Symptoms of CLD may resemble other conditions or medical problems. Always consult your baby's physician for a diagnosis.
Because CLD is a chronic disease and appears gradually, physicians must look at several factors. It is often diagnosed when a premature baby with respiratory problems continues to need additional oxygen after reaching 36 weeks gestational age. Chest x-rays compared with previous x-rays may show changes in the appearance of the lungs. The x-ray of lungs with CLD often have a bubbly, sponge-like appearance. X-rays are diagnostic tests which use invisible electromagnetic energy beams to produce images of internal tissues, bones, and organs onto film.
Specific treatment for CLD will be determined by your baby's physician based on:
Treatment of CLD may include:
CLD can be a long-term condition. Some babies with CLD require mechanical ventilators for several months. Some babies will continue to require oxygen when they go home from the hospital, but most can be weaned from oxygen by the end of their first year. Babies with CLD may be at increased risk for respiratory infection and may have to be re-hospitalized.
