Respiratory Flashcards
most common cause of bronchiolitis
RSV
peak incidence autumn + spring
presentation of bronchiolitis
course crepitations
wheeze
tachypnoea
hypoxia
what might a CXR show in bronchiolitis
hyperinflation / patchy infiltrative change
what is given to infants at risk of bronchiolitis?
e.g. children with chronic lung disease
palivizumab (RSV monoclonal antibody)
- given monthly as primary prophylaxis during RSV season
barking cough
croup
- viral laryngotracheal infection
presentation of croup
stridor, barking cough, increased work of breathing
tx croup
oral dexamethasone or nebulised budesonide
nebulised adrenaline if severe
fever, stridor, drooling, minimal cough
epiglottitis
tx epiglottitis
emergency - ENT/anaesthetic review to secure airway
IV antibiotics
organism that causes epiglottis
haemophilus influenza B
- rare now due to Hib vaccine
organism that causes whooping cough
bordatella pertussis
features of viral induced wheeze
wheeze following cough/coryza
tx viral induced wheeze
- SABA - salbutamol
2. Leukotriene receptor antagonist - Montelukast
what type of hypersensitivity is asthma
type 1 - IgE mediated
asthma signs and symptoms
expiratory wheeze
reduced peak flow
cough- worse at night
wheeze
breathlessness
chest tightness
spirometry results in asthma
FEV1 - reduced
FVC- normal
FEV1/FVC: <70%
asthma pathway in children
SABA
SABA + ICS
SABA + ICS + Leukotriene receptor antagonist
SABA + ICS + LABA
management of whooping cough
admit if under 6 months old
give clarithromycin if onset within 21 days
presentation of whooping cough
2-3 days of coryza
bouts of coughing - usually worse at night / after feeding
inspiratory whoop
vomiting
management of croup if steroids fail
oxygen + nebulised adrenaline
what organism causes croup
parainfluenza
most common cause of stridor in neonate
laryngomalacia
features of a viral wheeze
wheeze present with an upper respiratory tract infection, absent the rest of the time
management of a viral wheeze
1st line: salbutamol inhaler
2nd line: trial of montelukast / ICS
