Albuterol (Ventolin) Dosing for a 12-Month-Old Boy
For a 12-month-old boy with bronchospasm, administer 0.63 mg/3 mL of albuterol nebulizer solution every 4-6 hours as needed, or alternatively, 1-2 puffs (90 mcg per puff) via metered-dose inhaler with spacer and face mask every 4-6 hours. 1
Routine Bronchodilator Dosing
Nebulizer Solution (Preferred for This Age)
- Standard dose: 0.63 mg/3 mL nebulized every 4-6 hours as needed for bronchospasm 1
- Dilute the solution to a minimum of 3 mL with normal saline for optimal delivery 2
- Use oxygen as the preferred gas source for nebulization 1, 2
Metered-Dose Inhaler Alternative
- Standard dose: 1-2 puffs (90 mcg per puff) every 4-6 hours as needed 1
- Must use a spacer/holding chamber with face mask for children under 4 years of age 3, 1
- Puffs can be taken in 10-15 second intervals 1
Acute Exacerbation Dosing
For Moderate to Severe Acute Asthma
Nebulizer approach:
- Initial treatment: 0.075 mg/kg (minimum dose 1.25 mg) every 20 minutes for 3 doses 3
- Maintenance: 0.075-0.15 mg/kg up to 5 mg every 1-4 hours as needed 3
- For severe exacerbations, the dose may be doubled 1
MDI approach:
- Acute dosing: 4-8 puffs every 20 minutes for 3 doses, then every 1-4 hours as needed 1
- Use with spacer and face mask 3, 1
Addition of Ipratropium for Severe Exacerbations
- Add ipratropium bromide 0.25-0.5 mg to albuterol nebulization every 20 minutes for 3 doses during the first 3 hours of severe exacerbations 3
- Ipratropium provides benefit primarily in the first 3 hours and should not be continued once the patient is hospitalized 3
Critical Administration Considerations
Delivery Technique
- For nebulizer: ensure adequate flow rate (6-8 L/min) and dilute to minimum 3 mL total volume 2
- For MDI: proper spacer technique is essential—each puff should be delivered separately with 5-6 breaths through the spacer before the next puff 1
- Supplemental oxygen may be needed when compressed air-driven nebulizers are used 1
Monitoring Requirements
- Monitor heart rate, respiratory rate, and oxygen saturation during treatment 2, 4
- Watch for adverse effects including tachycardia, tremor, hypokalemia, and hyperglycemia 1, 2
- Administration can be repeated and dose adjusted until desired clinical effect is achieved, unless symptomatic tachycardia develops 1
Common Pitfalls to Avoid
Route Selection Error
- Avoid oral albuterol formulations when nebulized or inhaled options are available—they are slower acting, less effective, and have more systemic side effects 2
- Direct airway delivery provides rapid bronchodilation with lower systemic absorption 2
Dosing Errors in Young Infants
- At 12 months of age, weight-based dosing (0.075 mg/kg) may result in doses below the minimum effective dose of 1.25 mg 3
- Always use the minimum dose of 1.25 mg even if weight-based calculation yields a lower number 3
Spacer Technique Failure
- Failure to use a spacer with face mask in children under 4 years dramatically reduces drug delivery 3, 1
- The face mask must create a good seal around the nose and mouth 1
Clinical Decision Points
When to Escalate Therapy
- Increasing use or lack of expected effect indicates diminishing asthma control and requires reassessment 1
- Consider adding ipratropium for severe exacerbations in the first 3 hours 3, 1
- For life-threatening features, consider continuous nebulization at 0.5 mg/kg per hour (up to 10-15 mg/hour) in an intensive care setting 1
