Initial Treatment for Wheezing in a 12-Month-Old
For a 12-month-old infant with wheezing, administer salbutamol (albuterol) 2.5 mg via nebulizer or 4-8 puffs via metered-dose inhaler (MDI) with large volume spacer as first-line therapy for acute symptom relief. 1
Delivery Method Selection
- MDI with large volume spacer is the preferred delivery device and is equally effective to nebulization, potentially resulting in lower admission rates with fewer cardiovascular side effects. 1, 2
- If using nebulizer, administer salbutamol 2.5 mg via nebulizer every 20 minutes for up to 3 doses in the first hour if needed. 1
- The spacer device is easier to use and better accepted by children compared to nebulization. 3
When to Escalate Treatment
If the infant shows signs of severe respiratory compromise, immediately escalate care:
- Administer high-flow oxygen via face mask to maintain oxygen saturation >92% if hypoxemia is present. 1, 2
- Add ipratropium 100 mcg to nebulizer if initial beta-agonist treatment fails, as the combination reduces hospitalizations in severe exacerbations. 1, 2
- Give oral prednisolone 1-2 mg/kg (maximum 60 mg) immediately as a single dose for severe exacerbations requiring emergency treatment. 1, 2
Critical Assessment Points
Recognize features requiring immediate aggressive treatment:
- Too breathless to feed 1, 2
- Respiratory rate >50 breaths/minute 1, 2
- Pulse >140 beats/minute 1, 2
- Oxygen saturation <92% 1, 2
- Poor respiratory effort, cyanosis, or altered consciousness 1, 2
Important Clinical Context
- Most infants with wheezing have transient conditions associated with viral respiratory infections and do not have increased risks of asthma later in life. 4
- There is limited evidence for overall beneficial clinical effect of nebulized beta-agonists in all infants with acute wheezing, though some may respond. 4
- However, in infants with allergies or eczema (positive modified asthma predictive index), early recognition and treatment may be important, as these children are at increased risk of developing persistent asthma. 5
Common Pitfalls to Avoid
- Do not underestimate severity in very young children—assessment can be difficult, and any concerning features should prompt aggressive treatment. 1
- Ensure proper inhaler technique education to caregivers—most young children cannot achieve coordination for unmodified MDI use and require spacer devices. 1, 2
- Do not delay systemic corticosteroids while giving repeated albuterol doses alone if the infant shows signs of severe exacerbation. 2
Reassessment and Follow-Up
- Reassess response 15-30 minutes after starting treatment to evaluate effectiveness. 2, 1
- Relief treatment can be repeated 2-4 hours at home, but failure to respond or early deterioration requires immediate medical assessment. 2
- Provide written action plan for parents detailing when to increase bronchodilators and when to seek immediate care. 1, 2
