- <1 yrs
- 18 months and over
- 2-3 yrs
- > 3 yrs
- <1 yrs
what is the most common aetiological cause of bronchiolitis
respiratory synctical virus
what is the peak age on set of bronchiolitis
3-6 months
list 3 RFx for developing bronchiolitis
lung disease/pathology e.g.CF
congenital heart disease
immunodeficiency
prematurity
what time of the year are children with bronchiolitis most likely to present
increased presentation during the winter
list 1 underlying lung disease that increases the chance of developing bronchiolitis
cystic fibrosis
list 5 pathophysiological features of developing bronchiolitis
oedema inflammation mucus secretion necrosis of respiratory epithelial tissue small airway obstruction
on what day of presentation are children with bronchiolitis most likely to present with increased work of breathing
- day 1
- day 3
- day 5
- day 6
- day 3
on examination what sign would be suggested of respiratory distress in a child with bronchiolitis
intercostal and subcostal recession
what does intercostal and subcostal recession suggest in a child with bronchiolitis
use of accessory muscles to help with breathing due to respiratory distress
what might the parent suggest in the Hx that would indicate a child is having difficulty breathing
poor feeding
list 3 signs and 5 symptoms of bronchiolitis
signs: tachyponea low o2 sats grunting/nasal flaring tracheal tug intercostal/subcostal recession
symptoms: reduced feedings difficulty breathing cough and wheeze coryza mild fever
list 3 reasons for referral according to NICE in a child with bronchiolitis
child looks seriosuly unwell apnoea severe resp distress RR >70 central cyanosis persistent o2 sats <92%
what investigations might you consider to rule out pneumonia in a child with bronchiolitis
CXR
