Nebulizer Solutions and Administration Guidelines for Pediatric Patients

The American Academy of Allergy, Asthma, and Immunology recommends albuterol (salbutamol) as the primary bronchodilator used in nebulized form for pediatric patients with respiratory conditions, particularly asthma exacerbations 1, 2
For acute exacerbations, albuterol should be administered every 20 minutes for 3 doses, then every 1-4 hours as needed, with a typical dose of 0.15 mg/kg (minimum dose 2.5 mg) 1, 2

The American Academy of Pediatrics suggests that ipratropium bromide (anticholinergic) can be added to albuterol for children with moderate to severe asthma exacerbations 1
When using combination therapy, the recommended dose is 1.5 mL of solution containing 0.25 mg ipratropium bromide and 1.25 mg salbutamol 3

Masks are preferred for babies and young children when coordination is difficult, according to the British Thoracic Society 4
Mouthpieces should be used for nebulized steroids to prevent facial deposition and for antibiotics when a filter is needed, as recommended by the British Thoracic Society 4

Budesonide (Pulmicort) respules, a nebulized steroid, may be used in croup (500 μg) to reduce symptoms in the first two hours, as suggested by the British Thoracic Society 4, 5
Normal saline (0.9% sodium chloride) may be used to assist with physiotherapy, according to the British Thoracic Society 4

Water should never be used as a diluent as it may cause bronchoconstriction when nebulized, as warned by the British Thoracic Society 4
In patients with acute severe asthma, oxygen should be used as the driving gas for nebulization when possible, as recommended by the British Thoracic Society 4

For mild to moderate exacerbations, a metered-dose inhaler (MDI) with spacer can be as effective as nebulized therapy with appropriate technique and coaching, according to the American Academy of Allergy, Asthma, and Immunology 1, 2
Nebulizers are preferred when large drug doses are needed, when coordinated breathing is difficult, or when hand-held inhalers have been ineffective, as suggested by the British Thoracic Society 4

The American Academy of Pediatrics recommends a minimum dilution volume of 2-3 mL of normal saline for all ages to ensure adequate nebulization 6

For infants and children under 5 years, the dose is 0.15-0.30 mg/kg (minimum 2.5 mg), mixed in 2-3 mL normal saline, and administered every 20 minutes for 3 doses, then every 1-4 hours as needed 6, 7
For children 5-11 years, the dose is 1.25-5 mg, mixed in 3 mL of saline, and administered every 20 minutes for 3 doses, then every 1-4 hours as needed 7
For adults and children ≥12 years, the dose is 2.5-5 mg, mixed in 3 mL of saline, and administered every 20 minutes for 3 doses, then every 1-4 hours as needed 7

For refractory severe asthma, a dose of 0.5 mg/kg/hour up to 10-15 mg/hour is recommended, requiring dilution in a larger volume (25-30 mL) for 1 hour of continuous nebulization 6
The misconception that dilution ratios change with age stems from confusion between dose adjustment (which is age/weight-based) and dilution volume (which remains constant at 2-4 mL normal saline for adequate nebulization across all ages) 6, 7
