Bronchiolitis
Definition
bull Bronchiolitis is a first time wheezing with a viral respiratory infection
bull It is a common respiratory illness in children less than 24 months with its peak incidence between 3 to 6 months of age
bull Respiratory syncytial virus (RSV) is responsible for gt50 of cases
bull Other agents include parainfluenza adenovirus Mycoplasma and occasionally other viruses
bull Human metapneumovirus is an important primary cause of viral respiratory infection or it can occur as a co-infection with RSV
The common causal organisms of bronchiolitis
Epidemiology
bull A common respiratory illness especially in infants aged 1 to 6 months old
bull Cyclical periodicity with annual peaks occurs
in NovemberDecember and January
1)RSV infection incites a complex immune response Eosinophils degranulate and release eosinophil cationic protein which is cytotoxic to airway epithelium
2)Immunoglobulin E (IgE) antibody release may also be related to wheezing
3)Other mediators invoked in the pathogenesis of airway inflammation include chemokines such as interleukin 8 (IL-8) macrophage inflammatory protein (MIP) 1α
Pathophysiology
bull RSV-infected infants who wheeze express higher levels of interferon-γ in the airway as well as leukotrienes RSV co-infection with metapneumovirus can be more severe than monoinfection
Acute bronchiolitis is characterized by bronchiolar
obstruction with edema mucus and cellular debris
Resistance in the small air passages is increased
during both inspiration and exhalation but because
the radius of an airway is smaller during expiration
the resultant respiratory obstruction leads to early air
trapping and overinflation
If obstruction becomes complete there will be
resorption of trapped distal air and the child will
develop atelectasis
Clinical features
bull Coryzal symptoms precede a sharpdry coughincreasing breathlessness
bull Wheezing is oftenHigh pitchedexpiratorygtinspiratory
bull Feeding difficulty associated with increasing dyspnoea
bull Recurrent apnoea
bullSubcostal and intercostal recession
bullHyperinflation of the cheststernum prominentliver displaced downwards
bullFine end-inspiratory crackles
bullTachycardia
bullCyanosis or pallor

Investigations
A chest ray is not routinely requiredbut
recommended for children with
1)severe respiratory distress
2)unusual clinical features
3)an underlying cardiac or chronic respiratory
disorder
4)Admission to intensive care

2)Nutrition and Fluid therapyFeedingInfants admitted with viral brochiolitis frequently have poor feeding are at risk of aspiration and may be dehydratedSmall frequent feeds as tolerated can be allowed in children with moderate respiratory distressNaso gastric feeding maybe useful in these children who refuse to feed and also to empty the dilated stomachIntravenous fluids for children with severe respiratory distresscyanosisapnoeaFluid therapy should be restricted to maintenance requirement of 100mlkgday for infants
3)PharmacotherapybullInhaled β-2 agonistsA trial of nebulised β-2 agonistsgiven in oxygenmay be considered in infants with viral bronchiolitisVigilant and regular assessment of the child should be carried out if such a traetment is provided bullInhaled steroidsRandomised controlled trials of the use of inhaled steroids for treatment of viral brochiolitis demonstrated nomeaningful benefit

bull RSV-infected infants who wheeze express higher levels of interferon-γ in the airway as well as leukotrienes RSV co-infection with metapneumovirus can be more severe than monoinfection
Acute bronchiolitis is characterized by bronchiolar
obstruction with edema mucus and cellular debris
Resistance in the small air passages is increased
during both inspiration and exhalation but because
the radius of an airway is smaller during expiration
the resultant respiratory obstruction leads to early air
trapping and overinflation
If obstruction becomes complete there will be
resorption of trapped distal air and the child will
develop atelectasis
Clinical features
bull Coryzal symptoms precede a sharpdry coughincreasing breathlessness
bull Wheezing is oftenHigh pitchedexpiratorygtinspiratory
bull Feeding difficulty associated with increasing dyspnoea
bull Recurrent apnoea
bullSubcostal and intercostal recession
bullHyperinflation of the cheststernum prominentliver displaced downwards
bullFine end-inspiratory crackles
bullTachycardia
bullCyanosis or pallor

Investigations
A chest ray is not routinely requiredbut
recommended for children with
1)severe respiratory distress
2)unusual clinical features
3)an underlying cardiac or chronic respiratory
disorder
4)Admission to intensive care

Management outline
1)General measures
bullcareful assessment of the respiratory status and oxygenation is critical
bullArterial oxygenation by pulse oximetry Sp02 should be performed at presentation and maintain above 93-administer supplemental humidified oxygen if necessary
bullMonitor for signs of impending respiratory failure-inability to maintain satisfactory Spo2 on inspired oxygengt40 or a rising pCO2
bullVery young infants are at risk of apnoea require greater vigilance
2)Nutrition and Fluid therapyFeedingInfants admitted with viral brochiolitis frequently have poor feeding are at risk of aspiration and may be dehydratedSmall frequent feeds as tolerated can be allowed in children with moderate respiratory distressNaso gastric feeding maybe useful in these children who refuse to feed and also to empty the dilated stomachIntravenous fluids for children with severe respiratory distresscyanosisapnoeaFluid therapy should be restricted to maintenance requirement of 100mlkgday for infants
3)PharmacotherapybullInhaled β-2 agonistsA trial of nebulised β-2 agonistsgiven in oxygenmay be considered in infants with viral bronchiolitisVigilant and regular assessment of the child should be carried out if such a traetment is provided bullInhaled steroidsRandomised controlled trials of the use of inhaled steroids for treatment of viral brochiolitis demonstrated nomeaningful benefit

Prevention
Passive immunization with humanised RSV
specific monoclonal antibodies (Palivizumab)
prophylaxis is given during the expected
annual RSV outbreak season and is effective

the hisk risk categories
Recommended catagories of infants for passive immunization
