25
What are some risk factors of BRUE?
Feeding difficulties Recent URI \< 2 mo old Hx of prior episodes +/- premature birth/low birth weight, maternal smoking FU 2 PPM
26
What are the warning signs of BRUE?
Toxic appearance Lethargy Unexplained recurrent vomiting Respiratory distress Sustained cyanosis or LOC, CPR Bruising Hx or prior events Sibling Abuse or maltreatment Dysmorphic features. LTS VCR ABD
27
What does the AAP guidelines recommend for low risk?/
No need for routine testing and recommends against eval for systemic infection. For low risk they recommend parent education, CPR, and reassurance. High risk: r/o underlying conditions/ admit.
28
The most common cause of respiratory distress in premature infants is?
Hyaline membrane disease.
29
Deficiency of surfactant Surfactant also leaks into airspaces
Hyaline membrane disease
30
• decreases surface tension during expiration • allows alveoli stay partially expanded • PPX given to neonates \<27wks • Tx for infants with hyaline membrane dz
Surfactant
31
Lack of surfactant =
poor lung compliance and atelectasis
32
What is a big red flag of neonatal respiratory distress/Hyaline membrane dz?
If there is greater than 16 breaths per min. Absent breath sounds due to faulty alveoli Ground-glass appearance and or bronchogram. Ground-glass will be on atelactasis.
33
What is the treatment of Neonatal Respir Distress/Hyaline membrane dz?
O2, nasal CPAP, early intubation, surfactant, umbilical artery and vein line placement,
34
What will lessen the chance for Neonatal Respir Distress/Hyaline membrane dz if the mom takes what \> 24 hours prior to a pre-term birth?
Maternal steroids. Have better neonatal outcomes and lower chances of hyaline membrane disease.
35
Most common lethal inherited disease in caucasians?
CF
36
CF affects what organ systems mostly?
Lungs and GI
37
What is the pathophysiology of CF?
Disruption of salt and water balance. Mucus becomes thick and sticky.
38
If a patient has nasal polyps and cough what should you think?
CF
39
When is CF usually diagnosed?
6-8 mo old
40
Why does CF cause greasy malodorous stools?
The impact on the pancreas causing malabsorption.
41
Neonates with intestinal blockage is suspicious for?
CF
42
Undescended testicles Clubbing fingers (older kids)
CF
43
What are the normal ranges of the sweat chloride test?
30-60 Positive is greater than 60mmol/L
44
What other additional criteria do you need if the sweat chloride test is positive?
Either COPD Dx, Exocrine pancreatic insufficiency (via fecal test) or + fam hx of CF CFTR genetic test is easier than doing the sweat test and the additional criteria.
45
is the abnormal distortion and dilation of the bronchial tree.
Bronchiectasis
46
Loss of elasticity and will have tram tracks on CXR
Bronchiectasis
47
S/Sx are daily chronic cough with mucopurulen sputum over months to years.
Bronchiectasis
48
What is the standard dx for bronchiectasis?
CT scan
49
Are Brochiectasis airway obstruction reversible with bronchodilators?
No, the only helpful treatments are antibiotics and chest therapy.
50
defined as a single entity of oxygen requirement either at 28 postnatal days or 36 weeks postmenstrual age
Bronchopulmonary dysplasia
51
NICHD criteria also proposed that the requirement of supplemental oxygen be confirmed by using a physiologic test after a room air challenge test. What is a positive test?
If they drop below 90% on RA within 1 hour.
52
What is the most significant sequelea of ARDS
Bronchopulmonary dysplasia
53
Most cases of Bronchopulmonary dysplasia will have a birth weight below what?
1250 g
54
What is the main symptoms of bronchopulmonary dysplasia?
Tachypnea
55
What is the Tx of bronchopulmonary dysplasia?
Surfactant
56
In Bronchopulmonary dysplasia, muscles of arterioles can thicken leading to what?
Pulmonary hypertension.
57
This is usually a diagnosis of exclusion. It is a restrictive group of disorders. This is a parynchama problem as opposed to mucus or swollen airways.
Interstitial lung disease (diffuse lung disease)
58
Presents as unexplained respiratory failure in newborns, tachypnea, crackles, "velcro rales" hypoxemia, This is a chronic lung disease out of proportion to the degree of prematurity.
Interstitial lung disease (diffuse lung disease)
59
How do you Dx Interstitial lung disease (diffuse lung disease)?
Dignosis of exclusion
60
What is the treatment for Interstitial lung disease (diffuse lung disease)?
supportive, lung lavage, lung transplant.
