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

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

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

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

chest X-ray shows hyperinflation of the lungs with flattening of the diaphragm horizontal ribs and increased hilar bronchial markings Note chest X-ray is rarely helpful in bronchiolitis

The diagnosis is clinical particularly in a previously healthy infant presenting with a first-time wheezing episode during a community outbreak

A majority of chidren with viral bronchiolitis has mild illness and about 1 of these children require hospital admission

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

developed a runny nose and bit of a cough 2 days ago but has become progressively more chesty and has now gone off his feeds and is having far fewer wet nappies He has two older siblings who also have colds He was born at 34 weeksrsquo gestation but had no significant neonatal problems and went home at 2 weeks of age Both parents smoke but not in the houseHis mother had asthma as a child

Examination Max is miserable but alert His airway is clear He is febrile
