Bronchopulmonary Dysplasia (BPD)

Bronchopulmonary dysplasia (BPD) is a chronic respiratory disease that most often occurs in low-birthweight or premature infants who have received supplemental oxygen or have spent long periods of time on a breathing machine (mechanical ventilation), such as infants who have acute respiratory distress syndrome. BPD can also occur in older infants who experience abnormal lung development or some infants that have had an infection before birth (antenatal infection) or placental abnormalities (such as preeclampsia). Antenatal steroid treatment prior to preterm birth and early treatment with surfactant have reduced the need for high levels of respiratory support after birth.[rx]

Affected infants may have rapid, labored breathing and bluish discoloration of the skin due to low levels of oxygen in the blood (cyanosis). Infants are not born with BPD and the condition results from damage to the lungs due to the extremely fragile nature of the underdeveloped, immature lungs. Although most infants fully recover from BPD, some have sustained abnormalities of lung function and structure throughout adolescence and into adulthood. However, the condition can cause serious complications during infancy and often requires hospitalization and intensive medical care, especially during the first 2 years after birth.[rx]

Bronchopulmonary dysplasia, or BPD for short, is a lung condition that primarily affects premature babies. Babies born too early, before their lungs have fully developed, can struggle to breathe and require medical intervention. BPD is essentially a result of these underdeveloped lungs.

Types of BPD

There are two main types of BPD:

Classic BPD: This type occurs when a baby needs mechanical ventilation or extra oxygen for an extended period after birth.
New BPD: This type is seen in babies born today and is related to changes in medical practices. It often develops without the need for mechanical ventilation.

Causes of Bronchopulmonary Dysplasia

Premature Birth: The primary cause of BPD is being born too early, usually before 28 weeks of gestation.
Low Birth Weight: Babies with a very low birth weight are at higher risk of developing BPD.
Respiratory Distress Syndrome (RDS): RDS is a common breathing problem in premature babies and can lead to BPD.
Infection: Infections can damage a premature baby’s delicate lungs and increase the risk of BPD.
Prolonged Use of Mechanical Ventilation: Babies who require a ventilator for an extended period can develop BPD.
Inflammation: Lung inflammation due to various factors can contribute to BPD.
Maternal Smoking: Smoking during pregnancy increases the risk of BPD in the baby.
Genetics: Some genetic factors may make certain babies more susceptible to BPD.
Exposure to Environmental Toxins: Prenatal exposure to harmful substances can play a role in BPD development.
Multiple Births: Twins or triplets are more likely to experience BPD.
Maternal Health: Poor maternal health or certain medical conditions can increase the risk.
Male Gender: Boys are more likely than girls to develop BPD.
Oxygen Therapy: High levels of oxygen therapy can damage a baby’s lungs.
Blood Transfusions: Multiple blood transfusions may contribute to BPD.
Necrotizing Enterocolitis (NEC): NEC is a gastrointestinal problem that can affect premature infants and increase their BPD risk.
Patent Ductus Arteriosus (PDA): This heart condition can be associated with BPD.
Maternal Drug Use: Substance abuse during pregnancy can be a risk factor.
Poor Nutrition: Inadequate nutrition during pregnancy may increase the likelihood of BPD.
Prolonged Stay in Neonatal Intensive Care Unit (NICU): A lengthy stay in the NICU can expose babies to various risk factors.
Hemorrhage: Intraventricular hemorrhage (bleeding in the brain) can impact lung development and contribute to BPD.

Symptoms of Bronchopulmonary Dysplasia

Rapid Breathing: Babies with BPD often breathe faster than normal.
Wheezing: Wheezing sounds may be heard when the baby breathes.
Cyanosis: The baby’s skin may turn bluish due to a lack of oxygen.
Difficulty Feeding: BPD can make it hard for babies to feed and gain weight.
Flaring Nostrils: The baby’s nostrils may flare during breathing.
Retractions: The chest or ribs may visibly retract with each breath.
Low Oxygen Levels: Babies with BPD may have low oxygen levels in their blood.
Frequent Lung Infections: BPD can increase the risk of respiratory infections.
Coughing: Persistent coughing is a common symptom.
Irritability: Babies with BPD may seem fussy or uncomfortable.
Poor Weight Gain: Difficulty feeding can lead to poor weight gain.
Tiring Quickly: Babies may become tired quickly during feeding or other activities.
Difficulty Sleeping: Breathing problems can interfere with sleep.
Swelling: Swelling in the legs or abdomen may occur.
Noisy Breathing: Unusual noises while breathing, like grunting, can be a sign.
Stunted Growth: BPD can affect a baby’s overall growth and development.
Nasal Flaring: Flaring of the nostrils when breathing is common.
Frequent Hospitalization: Babies with BPD may need frequent hospital stays.
Dehydration: Difficulty feeding can lead to dehydration.
Developmental Delays: In severe cases, BPD can affect a baby’s long-term development.

Diagnostic Tests for Bronchopulmonary Dysplasia

Chest X-ray: This helps visualize the baby’s lungs and assess their condition.
Blood Gas Analysis: Measures oxygen and carbon dioxide levels in the blood.
Pulse Oximetry: A non-invasive way to monitor oxygen levels in the blood.
Bronchoscopy: A tiny camera is used to examine the airways.
Lung Function Tests: These assess how well the baby’s lungs are working.
Echocardiogram: Checks the baby’s heart for any associated problems.
Complete Blood Count (CBC): Measures various blood components for clues about the baby’s health.
C-reactive Protein (CRP) Test: Helps detect inflammation in the body.
Respiratory Viral Panel: Identifies viral infections that could worsen BPD.
Feeding Evaluation: To assess if feeding difficulties are contributing to BPD.
Electrocardiogram (ECG): Measures the heart’s electrical activity.
Thyroid Function Tests: Checks thyroid hormone levels.
Magnetic Resonance Imaging (MRI): Sometimes used for a more detailed look at the lungs.
Sputum Culture: Tests respiratory secretions for infections.
Pulmonary Function Tests (PFTs): Measures lung function in older children with BPD.
Bone Density Scan: To assess bone health, especially if corticosteroids are used.
Genetic Testing: In cases where genetic factors are suspected.
Ultrasound: May be used to examine blood vessels or organs.
Nasopharyngeal Culture: Collects samples from the nose and throat to detect infections.

Treatments for Bronchopulmonary Dysplasia

Oxygen Therapy: Providing supplemental oxygen to maintain proper oxygen levels in the blood.
Ventilation Support: Mechanical ventilation or non-invasive ventilation to assist breathing.
Surfactant Replacement: Administering surfactant to improve lung function.
Diuretics: Medications to help remove excess fluid from the body, reducing strain on the lungs.
Bronchodilators: Drugs that relax airway muscles to improve airflow.
Nutritional Support: Ensuring adequate nutrition for growth and healing.
Inhaled Nitric Oxide: Used in severe cases to improve oxygenation.
Corticosteroids: Sometimes prescribed to reduce lung inflammation.
Antibiotics: If an infection is present, antibiotics are essential.
Fluid Management: Careful monitoring and control of fluid intake to prevent fluid buildup in the lungs.
Nasal Continuous Positive Airway Pressure (NCPAP): A gentler form of respiratory support.
Pulmonary Rehabilitation: Programs to help improve lung function and overall health.
Home Oxygen Therapy: For babies discharged from the hospital.
Positioning Techniques: Placing the baby in specific positions to aid breathing.
Surveillance for Complications: Regular check-ups to catch and address issues early.
Parent Education: Teaching parents how to care for their baby’s unique needs.
Surgery: In rare cases, surgery may be necessary to repair lung or heart defects.
Neurodevelopmental Follow-up: Monitoring and support for developmental delays.
Palliative Care: For severe cases where curative treatment is not possible.
Supportive Care: Ensuring comfort and quality of life.

Newborns with BPD initially require care in the hospital. Treatment may include mechanical ventilation. Ventilators are only used when necessary to help sustain effective breathing and oxygen for the baby and affected infants are taken off the breathing machine as early as possible but only when the infant has clearly shown the ability to breathe effectively and without distress. [rx]Many infants still require supplemental oxygen after being taken off mechanical ventilation, and the amount of oxygen is progressively reduced by close monitoring of the body’s oxygen level by serial measurements with a pulse oximeter. Proper nutritional management is also necessary to ensure the proper growth and development of the lungs. Some affected infants may require the insertion of a gastrointestinal (GI) tube directly into the stomach to ensure a sufficient intake of calories and nutrients. Because infants with BPD are at risk for the accumulation of excess fluid in the lungs, daily fluid intake may be monitored and adjusted.[rx]

Infants with BPD may receive different medications including bronchodilators, diuretics and antibiotics. Bronchodilators are medications that widen the airway tubes and improve the flow of air through the lungs. Diuretics are medications that reduce the amount of water in the body and may be administered to help remove excess fluid in the lungs. Antibiotics are used to help control infections and prevent pneumonia. In addition, intermittent use of steroids may reduce lung inflammation and congestion, reducing the need for high levels of respiratory support and oxygen. However, early and high doses of steroids may have adverse effects on neurocognitive and developmental outcomes. As a result, steroids are used selectively later in the clinical course, and for shorter periods of time.[rx]

Surfactant: A medication that helps the lungs stay open.
Bronchodilators: Drugs like albuterol or levalbuterol to open airways.
Corticosteroids: Such as dexamethasone or prednisone to reduce inflammation.
Diuretics: Like furosemide to remove excess fluid from the body.
Antibiotics: Used to treat and prevent infections.
Nitric Oxide: Inhaled to help with oxygenation.
