Why does atelectasis occur in newborns?

What Causes Atelectasis in Newborns? Prematurity: Atelectasis is a relatively common complication of prematurity. Premature babies may not have enough surfactant, a chemical that helps keep alveoli open. This can cause small airway collapse and respiratory distress syndrome (RDS).

What are 3 causes of atelectasis?

Possible causes of nonobstructive atelectasis include:

  • Injury. Chest trauma — from a fall or car accident, for example — can cause you to avoid taking deep breaths (due to the pain), which can result in compression of your lungs.
  • Pleural effusion.
  • Pneumonia.
  • Pneumothorax.
  • Scarring of lung tissue.
  • Tumor.

What would cause a collapsed lung in a newborn?

The most common cause of pneumothorax is respiratory distress syndrome. This is a condition that occurs in babies who are born too early (premature). The baby’s lungs lack the slippery substance (surfactant) that helps them stay open (inflated). Therefore, the tiny air sacs are not able to expand as easily.

What causes atelectasis?

Atelectasis, the collapse of part or all of a lung, is caused by a blockage of the air passages (bronchus or bronchioles) or by pressure on the lung. Risk factors for atelectasis include anesthesia, prolonged bed rest with few changes in position, shallow breathing and underlying lung disease.

What causes atelectasis kids?

Atelectasis can be caused by a child swallowing a foreign object. The object then blocks the airways. Atelectasis may also be caused by a long bed rest. It may also be caused by not taking full breaths.

Can atelectasis be congenital?

Congenital atelectasis occurs more frequently in premature and feeble babies. Other causes are birth injury to the central nervous system, narcotization, inhaled meconium or amniotic fluid, and prolonged or difficult labor.

How can atelectasis be prevented?

To prevent atelectasis:

  1. Encourage movement and deep breathing in anyone who is bedridden for long periods.
  2. Keep small objects out of the reach of young children.
  3. Maintain deep breathing after anesthesia.

Can atelectasis go away?

Treatment of atelectasis depends on the cause. Mild atelectasis may go away without treatment. Sometimes, medications are used to loosen and thin mucus. If the condition is due to a blockage, surgery or other treatments may be needed.

What is the usual cause of atelectasis seen in the premature neonate?

The most common causes of atelectasis in the neonatal period are respiratory distress syndrome, bacterial pneumonia, meconium aspiration syndrome, gastroesophageal reflux, bronchopulmonary dysplasia, pleural effusion, and pneumothorax.

Can a newborn live with one lung?

By the time Grace was born, her chances of survival dropped to one in five. She was surviving after her birth with just 20 percent functionality in one lung. “That’s pretty uncommon,” said Patricia Chess, M.D., a neonatologist at Golisano Children’s Hospital who treated Grace.

Who is at risk for atelectasis?

You may be at higher risk of atelectasis if you smoke or have other conditions, including obesity, sleep apnea, or lung diseases such as asthma, COPD, or cystic fibrosis. You are also at higher risk if you recently had surgery.
