What is the cause of RDS of the newborn?
RDS of the newborn, also known as hyaline membrane disease (HMD), is a major cause of morbidity and mortality in premature newborns. None of the other options are considered the chief predisposing factors for RDS. (1301) What is the primary cause of respiratory distress syndrome (RDS) of the newborn? Surfactant deficiency
How is respiratory distress syndrome (RDS) of the newborn treated?
advances in the treatment of respiratory distress syndrome (RDS) of the newborn Administering glucocorticoids to women in preterm labor accelerates the maturation of the fetus's lungs. Treatment includes the instillation of exogenous surfactant down an endotracheal tube of infants weighing less than 1000 g.
Could preventing premature births end RDS?
According to the American Thoracic Society, “ Preventing premature births could nearly eliminate RDS .” 5 In the meantime, research and experimentation continue around the globe, especially in countries that are high in preterm births and low in resources like ventilators and CPAP.
What is hyaline membrane disease of the newborn (RDS)?
RDS of the newborn, also known as hyaline membrane disease (HMD), is a major cause of morbidity and mortality in premature newborns. None of the other options are considered the chief predisposing factors for RDS. (1301)
What is the primary problem resulting from respiratory distress syndrome RDS of the newborn?
Infant respiratory distress syndrome is a lung disorder that tends to affect premature infants. Major symptoms include difficulty in breathing and collapsed lungs, potentially requiring mechanical ventilation or positive end-expiratory pressure (PEEP).
What is the chief predisposing factor for RDS of the newborn?
The results of this study show that selective cesarean section, severe birth asphyxia, PROM, male sex, and gestational glucose intolerance or diabetes are the main risk factors of RDS in full-term neonates.
Which one of the following is a primary cause of respiratory distress syndrome RDS of the newborn quizlet?
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.
What is the primary cause of respiratory distress syndrome RDS of the newborn immature immune system small alveoli surfactant deficiency anemia?
Neonatal respiratory distress syndrome (RDS) occurs from a deficiency of surfactant, due to either inadequate surfactant production, or surfactant inactivation in the context of immature lungs. Prematurity affects both these factors, thereby directly contributing to RDS.
How is RDS managed at birth?
With treatment, many newborns that are diagnosed with RDS will recover. Some common treatments include those listed below. Nasal continuous positive airway pressure (nCPAP): This device provides breathing support by gently pushing air into the baby's lungs through prongs placed in the nose.
What are the risk factors for RDS?
Other factors that can increase the risk for RDS include:A brother or sister who had RDS.Diabetes in the mother.Cesarean delivery or induction of labor before the baby is full-term.Problems with delivery that reduce blood flow to the baby.Multiple pregnancy (twins or more)Rapid labor.
What is the treatment of choice for the early stages of RDS in premature infants?
Treatment for RDS may include: Placing a breathing tube into your baby's windpipe (trachea) Having a ventilator breathe for the baby. Extra oxygen (supplemental oxygen)
How is respiratory distress treated in children?
Treatment for RDS may include:Placing an endotracheal (ET) tube into the baby's windpipe.Mechanical breathing machine (to do the work of breathing for the baby)Supplemental oxygen (extra amounts of oxygen)Continuous positive airway pressure (CPAP). ... Surfactant replacement with artificial surfactant.More items...
How can respiratory distress syndrome 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.
What happens in a patient with infant respiratory distress syndrome and the changes that occur in the respiratory system of the patient?
This lung scarring is called bronchopulmonary dysplasia (BPD). Symptoms of BPD include rapid, shallow breathing and shortness of breath. Babies with severe BPD usually need additional oxygen from tubes into their nose to help with their breathing. This is usually stopped after a few months, when the lungs have healed.
Can you recommend a treatment for a newborn suffering from respiratory distress?
Most neonates with respiratory distress can be treated with respiratory support and noninvasive methods. Oxygen can be provided via bag/mask, nasal cannula, oxygen hood, and nasal continuous positive airway pressure. Ventilator support may be used in more severe cases.
What are the major factors in the pathophysiology of RDS?
PATHOPHYSIOLOGY: The primary cause of RDS is inadequate pulmonary surfactant. The structurally immature and surfactant-deficient lung has ↓ compliance and a tendency to atelectasis; other factors in preterm infants that ↑ the risk of atelectasis are decreased alveolar radius and weak chest wall.
Which of the following neonates is at the highest risk for cold stress?
Postdates babies are at high risk for cold stress syndrome because while still in utero they often metabolize the brown adipose tissue for nourishment when the placental function deteriorates.
Which condition may cause intrauterine asphyxiation?
low birth weight. abnormal position of the fetus during delivery. preeclampsia or eclampsia. history of birth asphyxia in a previous birth.
Which maternal factors should the nurse consider contributory to a newborn being large for gestational age?
Diabetes mellitus, postdates gestation, and prepregnancy obesity are the maternal factors the nurse should consider that could lead to a newborn being large for gestational age.
Which of the following would the nurse expect to find in a newborn who is considered small for gestational age?
A small-for-gestational-age newborn typically has a sunken abdomen, wide skull sutures, decreased subcutaneous fat stores, poor muscle tone over buttocks and cheeks, and a thin umbilical cord. A nurse is caring for a baby girl born at 34 weeks' gestation.
How do antenatal corticosteroids affect RDS?
Antenatal corticosteroids accelerate fetal lung maturation by increasing the activity of enzymes responsible for surfactant biosynthesis, resulting in improved lung compliance.
Does antenatal corticosteroid help with lung injury?
Maternal antenatal corticosteroid treatment has improved survival of preterm neonates and lowered the incidence of brain injury. After birth, exogenous surfactant administration improves lung compliance and oxygenation, resulting in reductions in the incidence of pneumothorax and of death.
What is RDS in newborns?
Premature birth. RDS of the newborn, also known as hyaline membrane disease (HMD), is a major cause of morbidity and mortality in premature newborns. None of the other options are considered the chief predisposing factors for RDS.
Why is it difficult for neonates to overcome atelectasis?
The primary problem is atelectasis, which causes significant hypoxemia and is difficult for the neonate to overcome because a significant negative inspiratory pressure is required to open the alveoli with each breath. None of the other options are considered a primary problem associated with RDS.
What is ARDS pulmonary?
ARDS is characterized by progressive respiratory distress, severe hypoxemia refractory to treatment with supplemental oxygen, decreased pulmonary compliance, bilateral infiltrates on chest x-ray imaging, and no evidence of heart failure.
What causes croup in infants?
In 85% of children with croup, a virus is the cause, most commonly parainfluenza. However, other viruses such as influenza A or respiratory syncytial virus (RSV) also can cause croup. (1295-96) What is the chief predisposing factor for respiratory distress syndrome (RDS) of the newborn? Premature birth.
Why does my baby have a head bobbing sensation?
Infants may appear to be "head bobbing" because of sternocleidomastoid muscle use. Pulsus paradoxus may also be present. The child may appear anxious or diaphoretic, which are important signs of respiratory compromise. Clubbing of fingers and toes is not typically associated with asthma.
When do infants have to use nose breathers?
Infants up to 2 to 3 months of age are obligatory nose breathers and are unable to breathe in through their mouths. Nasal congestion is therefore a serious threat to a young infant. This selection is the only option that accurately describes why nasal congestion is a serious threat to young infants. (1290)
What is respiratory failure?
It is defined as respiratory failure of acute onset characterized by severe hypoxemia that is refractory to treatment with supplemental oxygen, bilateral infiltrates on chest x-ray imaging, and no evidence of heart failure, as well as decreased pulmonary compliance.
