Asthma Management in Infants Under 12 Months

Acute Symptom Management

For immediate relief of acute symptoms, administer salbutamol 2.5 mg via nebulizer or 4-8 puffs via metered-dose inhaler (MDI) with large volume spacer, as MDI with spacer is equally effective to nebulization and may result in lower admission rates with fewer cardiovascular side effects 1
For acute exacerbations requiring emergency treatment, give high-flow oxygen via face mask to maintain oxygen saturation >92% 1, 2, 3
In emergency treatment, administer nebulized salbutamol 2.5 mg every 20 minutes for up to 3 doses in the first hour 1
Add ipratropium 100 mcg to nebulizer if initial beta-agonist treatment fails 1, 2
Give oral prednisolone 1-2 mg/kg (maximum 60 mg) immediately as a single dose 1, 3

Underestimating severity in very young children—assessment can be difficult, and any concerning features should prompt aggressive treatment 4
Failing to provide proper inhaler technique education to caregivers—most young children cannot achieve coordination for unmodified MDI use and require spacer devices 1

Seek immediate medical attention if the infant has too breathless to feed 4, 1
Seek immediate medical attention if the infant has respiratory rate >50 breaths/minute 4, 1
Seek immediate medical attention if the infant has pulse >140 beats/minute 4, 1
Seek immediate medical attention if the infant has oxygen saturation <92% 1, 2, 3
Seek immediate medical attention if the infant has poor respiratory effort, cyanosis, or altered level of consciousness 4, 2

After initiating therapy, reassess response within 2-4 weeks of starting controller therapy and ensure proper medication delivery technique before escalating therapy 1
Provide written action plan for parents detailing when to increase bronchodilators and when to seek immediate care 1
