% due to RSV? remainder due to?

80% RSV - rest = metapneumonvirus, parainfluenza, rhinovirus, adenovirus, influenza, mycoplasma pneumoniae


% of infants admitted a year? rare after? annually what happens?

Ix bronchiolitis

PCR analysis of NPsecretions
CXR if complicated
pulse oximetry to monitor sats.
ABG/VBG if severe and monitoring for hypercapnia


What could CXR show

CXR if complicated - can show hyperinflation from trapped air due to small airway obstruction, and focal atelectasis (collapse)


MGMT bronchiolitis

humidified O2 by nasal cannulae
monitor for apnoea
BG/IV fluids
assisted vent via CPAP facemask or nasal
full ventilation in some


infection control?

RSV infection control - hand hygiene and other measures, prevent cross infection to other infants
