respiratory distress syndrome of newborns, also called hyaline membrane disease, a common complication in infants, especially in premature newborns, characterized by extremely laboured breathing, cyanosis (a bluish tinge to the skin or mucous membranes), and abnormally low levels of oxygen in the arterial blood.

What are the five symptoms of respiratory distress in the newborn?

Symptoms
  • Bluish color of the skin and mucus membranes (cyanosis)
  • Brief stop in breathing (apnea)
  • Decreased urine output.
  • Nasal flaring.
  • Rapid breathing.
  • Shallow breathing.
  • Shortness of breath and grunting sounds while breathing.
  • Unusual breathing movement (such as drawing back of the chest muscles with breathing)

What is respiratory distress of the newborn?

Newborn respiratory distress syndrome (NRDS) happens when a baby's lungs are not fully developed and cannot provide enough oxygen, causing breathing difficulties. It usually affects premature babies. It's also known as infant respiratory distress syndrome, hyaline membrane disease or surfactant deficiency lung disease.

How is infant respiratory distress treated?

Treatments for RDS include surfactant replacement therapy, breathing support from a ventilator or nasal continuous positive airway pressure (NCPAP) machine, or other supportive treatments. Most newborns who show signs of RDS are quickly moved to a neonatal intensive care unit (NICU).

Which medication is appropriate for a neonate with respiratory distress syndrome?

Drugs such as corticosteroids, proterelin (thyrotropin-releasing hormone) and ambroxol have all been administered to mothers to promote fetal lung maturation, but of these only corticosteroids have been proven to be of benefit. The management of RDS includes assisted ventilation and surfactant replacement therapy.

How is neonatal respiratory acidosis treated?

Treatment of respiratory acidosis

The latter is achieved by either increasing the tidal volume (increasing PIP or decreasing PEEP), or increasing the set tidal volume if the baby is ventilated using a targeted ventilation mode such as 'volume guarantee', or by increasing the respiratory rate.

What is the role of surfactant in neonatal lung development?

The surfactant mixture is an essential group of molecules to support air breathing. Thus, preterm infants, who are born with immature lungs and are surfactant deficient, develop respiratory distress syndrome after being born.

What causes RDS in premature babies?

What causes RDS in premature babies? RDS occurs when there is not enough surfactant in the lungs. Surfactant is a liquid made by the lungs that keeps the airways (alveoli) open. This liquid makes it possible for babies to breathe in air after delivery.

How can you prevent neonatal respiratory distress syndrome?

How can RDS in premature babies be prevented? Preventing a premature birth is the main way to prevent RDS. When a premature birth can't be prevented, you may be given corticosteroids before delivery. These medicines may greatly lower the risk and severity of RDS in the baby.

Why do C section babies have breathing problems?

Babies delivered by C-section (without labor) are more likely to have this condition. This is because without the hormone changes of labor the fluid in the lungs is still there. The baby has to work to reabsorb it after birth. Babies of moms with asthma and diabetes may also be more likely to have this condition.

How does a neonate can develop breathing respiratory difficulties?

The earlier the infant is born, the more likely it is for the baby to have RDS and to need extra oxygen and help breathing. RDS is caused by the baby not having enough surfactant in the lungs. Surfactant is a liquid made in the lungs at about 26 weeks of pregnancy. As the fetus grows, the lungs make more surfactant.

How do you assess neonatal respiratory distress?

Assessment for respiratory distress may differ depending on clinical setting but should include at least some of the following parameters: (1) measurement of respiratory rate (normal 40–60); (2) observation for increased work of breathing: inspiratory sternal, intercostal and subcostal recession/in-drawing, tracheal ...

What is the cause of respiratory distress?

ARDS happens when the lungs become severely inflamed from an infection or injury. The inflammation causes fluid from nearby blood vessels to leak into the tiny air sacs in your lungs, making breathing increasingly difficult.

What is neonatal pneumonia?

Neonatal pneumonia is lung infection in a neonate. Onset may be within hours of birth and part of a generalized sepsis syndrome or after 7 days and confined to the lungs. Signs may be limited to respiratory distress or progress to shock and death. Diagnosis is by clinical and laboratory evaluation for sepsis.

How is RDS diagnosed?

RDS is usually diagnosed by a combination of assessments, including the following:
  1. Appearance, color, and breathing efforts (indicate a baby's need for oxygen).
  2. Chest X-rays of lungs. ...
  3. Blood gases (tests for oxygen, carbon dioxide and acid in arterial blood). ...
  4. Echocardiography.

What are the signs of neonatal distress for the prioritization of care?

The signs and symptoms of neonatal RDS are: - Tachypnoea (respiratory rate >60/minute); - Nasal flaring (from the use of alae nasi as accessory muscles); - Sternal and intercostal recession (due to compliant chest wall and noncompliant lungs);

What is the most common complication of surfactant administration in a preterm neonate?

Bronchopulmonary dysplasia is the most common respiratory complication in preterm infants who survive prolonged mechanical ventilation. Surfactant administration reduces distress syndrome and consequently ventilation and prolonged oxygen therapy.

What causes distress in newborn?

The most common etiology of neonatal respiratory distress is transient tachypnea of the newborn; this is triggered by excessive lung fluid, and symptoms usually resolve spontaneously. Respiratory distress syndrome can occur in premature infants as a result of surfactant deficiency and underdeveloped lung anatomy.

What happens in RDS?

RDS happens when a baby's lungs don't make enough of a fatty substance called surfactant (ser-FAK-tent). Surfactant is made in the last few weeks of pregnancy. It helps tiny air sacs in the lungs called alveoli (al-VEE-oh-lye) open more easily. These sacs fill with air when a baby breathes after birth.

Why RDS is called hyaline membrane disease?

The word "hyaline" comes from the Greek word "hyalos" meaning "glass or transparent stone such as crystal." The membrane in hyaline membrane disease looks glassy. Hyaline membrane disease is now commonly called respiratory distress syndrome (RDS). It is caused by a deficiency of a molecule called surfactant.

What are the complications of RDS?

What are the complications associated with neonatal respiratory distress syndrome?
  • air buildup in the sac around the heart, or around the lungs.
  • intellectual disabilities.
  • blindness.
  • blood clots.
  • bleeding into the brain or lungs.
  • bronchopulmonary dysplasia (a breathing disorder)
  • collapsed lung (pneumothorax)
  • blood infection.

How does surfactant work in neonates?

Surfactant is a liquid made by the lungs that keeps the airways (alveoli) open. This liquid makes it possible for babies to breathe in air after delivery. An unborn baby starts to make surfactant at about 26 weeks of pregnancy.

What is neonatal surfactant?

Neonate – infant less than 28 days old. Surfactant - complex and highly surface active material composed of lipids and proteins which is found in the fluid lining the alveolar surface of the lungs, which serves to reduce alveolar surface tension. RDS – respiratory distress syndrome.

Which action best explains the main role of surfactant in the neonate?

Which action best explains the main role of surfactant in the neonate? Surfactant works by reducing surface tension in the lung. Surfactant allows the lung to remain slightly expanded, decreasing the amount of work required for inspiration.

At what gestational age is surfactant produced?

Surfactant is made by the cells in the airways and consists of phospholipids and protein. It begins to be produced in the fetus at about 24 to 28 weeks of pregnancy, and is found in amniotic fluid between 28 and 32 weeks. By about 35 weeks gestation, most babies have developed adequate amounts of surfactant.
