What is atelectasis in premature babies?
Atelectasis is a condition that causes the lungs of premature babies to collapse, which is why it’s also known as “collapsed lung” syndrome. It’s often triggered by respiratory distress syndrome.
Why are infants predisposed to atelectasis?
The main factors that contribute to atelectasis in premature neonates are the use of mechanical ventilation, poor endotracheal tube (ETT) placement, mucus plugs, elective or accidental extubation and diseases such as bacterial pneumonia, bronchopulmonary dysplasia, pleural effusion, respiratory distress syndrome.
What causes infant respiratory distress syndrome?
RDS is caused by a lack of surfactant in the lungs. The lungs of a fetus start making surfactant during the third trimester, which starts after the 26th week of pregnancy. Surfactant is a foamy substance that keeps the lungs fully expanded so that newborns can breathe in air once they are born.
What is Reticulogranular pattern?
Reticulogranularity. A reticulogranular pattern, or ground glass appearance, uniformly distributed throughout both lung fields is. characteristic of RDS. Because of surfactant deficiency, alveoli.
What causes atelectasis in kids?
Atelectasis in children is often caused by a blockage in the airway. To decrease atelectasis risk, keep small objects out of reach of children. In adults, atelectasis most commonly occurs after major surgery. If you’re scheduled for surgery, talk with your doctor about strategies to reduce your risk.
What are the three types of atelectasis?
The term atelectasis can also be used to describe the collapse of a previously inflated lung, either partially or fully, because of specific respiratory disorders. There are three major types of atelectasis: adhesive, compressive, and obstructive.
What causes atelectasis?
Atelectasis is caused by a blockage of the air passages (bronchus or bronchioles) or by pressure on the outside of the lung. Atelectasis is not the same as another type of collapsed lung called pneumothorax, which occurs when air escapes from the lung.
What are Hyperaerated lungs?
Hyperinflated lungs occur when air gets trapped in the lungs and causes them to overinflate. Hyperinflated lungs can be caused by blockages in the air passages or by air sacs that are less elastic, which interferes with the expulsion of air from the lungs.
Are premature babies lungs underdeveloped?
Topic Overview. Particularly when an infant is born before 36 weeks’ gestation , the lungs are immature, and the body has limited muscle strength and energy for breathing. So the premature infant may not get enough oxygen. This can cause serious health problems.
How is atelectasis treated in children?
The goal of treatment is to re-expand the lung. If a foreign object is in the lung, it is removed. Moving the child into different positions and gently tapping the chest will reinflate the lung. The child may also use a special device called an incentive spirometer that helps them breathe deeply.
How is atelectasis caused?
What is atelectasis in infants?
Atelectasis in Infants. Definition. Atelectasis is a collapse in part of the lungs. Normally, air passes through the airways into small sacs of the lungs.
What is alveolar atelectasis?
It occurs when the tiny air sacs (alveoli) within the lung become deflated or possibly filled with alveolar fluid. Atelectasis is one of the most common breathing (respiratory) complications after surgery.
What is atelectasis after surgery?
Atelectasis is one of the most common breathing (respiratory) complications after surgery. It’s also a possible complication of other respiratory problems, including cystic fibrosis, lung tumors, chest injuries, fluid in the lung and respiratory weakness.
What is the prevalence of atelectasis in mechanical ventilation?
Data in the literature indicate that 42% of neonates on mechanical ventilation develop atelectasis(28), which can occur when the endotracheal tube is either above or below the correct position. In adults admitted to the intensive care unit, atelectasis reportedly occurs most often in the lower lobes.
