Respiratory Illness of Lower Airway - Bronchiolitis, Pneumonia, Asthma, Cystic Fibrosis Flashcards
where does lower airway infections happen and what is the general thing that they do to the body
-Considered the “reactive” portion of the lower respiratory tract
-Includes bronchi and bronchioles
-Cartilaginous support is not fully developed until adolescence
-Constriction of airways
-Trapped air
what is bronchiolitis
-Acute inflammatory disease
-Small airway obstruction.
-RSV (Respiratory Syncytial virus): 50 to 90% of cases, 5 to 40 % of pneumonia cases, contact precautions
-Peak incidence is 2 to 5 months of age.
what is pneumonia
-Causative organism varies greatly by age
-The most useful classification is etiologic agent: Viral, Bacterial, Mycoplasmal, Aspiration of foreign substances
what is the RSV pneumonia presentation & diagnosis
-Seasonal Presentation
-Under two years
-Clinical Presentation, Significant respiratory distress: tachypnea, retractions, wheezing, rales, prolonged expiration
-Hyperinflated chest x-ray
-Rapid testing: swab
-hear rales (crackles is different in pneumonia)
how do you manage RSV pneumonia
-Apnea (especially <6months)
-Oxygen
-May be NPO
-Maintenance fluids
-Albuterol nebulized
-Antibiotics if uncertain dx
what are the RSV medications
-Ribavirin (anti-viral) for high-risk patients (i.e.. congenital heart disease, cystic fibrosis, immunocompromised)
-Steroids only with asthma-like presentation
-Prophylaxis (Monthly): Respigam (IV Immunoglobulin) & Synagis (IM)
explain aspiration pneumonia
-Risk for a child with feeding difficulties
-Prevention of aspiration
-Feeding techniques and positioning
-Avoid aspiration risks: Oily nose drops, Solvents, Talcum powder
what is the most common lethal genetic illness among white children
cystic fibrosis
what is cystic fibrosis
-Exocrine gland dysfunction that produces multisystem involvement
-Autosomal recessive trait
what is the prognosis of cystic fibrosis
-CF continues to be a progressive, incurable disease
-Organ transplantation has increased the survival rate
what are the respiratory cystic fibrosis symptoms
Cough, wheezing, increased work of breathing, frequent bouts of respiratory illness, thick secretions
what are the GI manifestations of cystic fibrosis
-Excretion of undigested food in stool
-Stool is bulky, frothy and foul smelling
-Wasting
what are the endocrine manifestations of cystic fibrosis
-Insulin resistance, insulin deficiency, unstable glucose homeostasis = microvascular complications.
-Bone health
what type of chest do cystic fibrosis patients have
barrel chest due to hyperinflammation and clubbing
what are the treatment goals for cystic fibrosis
-Prevent or minimize pulmonary complications: CPT, bronchodilators, antibiotics, steroids, Dornase alpha (decreases viscosity of mucous – aerosolized medication)
-Adequate nutrition for growth: Pancreatic enzymes, high protein and high calorie diet
-Assist the child and family in adapting to a chronic illness
