Asthma Management in Pediatric Patients

Introduction to Asthma Treatment

• The American Academy of Pediatrics recommends administering high-flow oxygen via face mask to maintain SpO₂ >92% and salbutamol 5 mg via nebulizer or 4-8 puffs via MDI with spacer every 20 minutes for up to 3 doses in the first hour, with oral prednisolone 1-2 mg/kg (maximum 40-60 mg) immediately, and adding ipratropium bromide 100-250 mcg to each salbutamol dose for the first hour 1, 2

Oxygen Therapy

• The European Respiratory Society recommends starting high-flow oxygen immediately via face mask to maintain oxygen saturation >92% and continuing throughout treatment until SpO₂ remains stable above this threshold 1, 2, 3

Bronchodilator Administration

• The American Academy of Pediatrics recommends salbutamol dosing of 2.5 mg for children ≤2 years or 5.0 mg for children >2 years via nebulizer every 20 minutes for up to 3 doses in the first hour, with alternative MDI delivery of 4-8 puffs via MDI with large volume spacer every 20 minutes for 3 doses 1, 2

Systemic Corticosteroids

• The American Academy of Pediatrics recommends oral prednisolone 1-2 mg/kg (maximum 40-60 mg) immediately upon recognition of acute severe asthma, with oral corticosteroids preferred when the child can swallow and is not vomiting 1, 2, 4

Ipratropium Bromide

• The American Academy of Pediatrics recommends adding ipratropium bromide 100-250 mcg via nebulizer to each salbutamol dose every 20 minutes for 3 doses in the first hour, then every 6 hours, with alternative MDI dosing of 4-8 puffs every 20 minutes for 3 doses 1, 2

Severity Assessment

• The American Academy of Pediatrics defines severe exacerbation features as too breathless to talk or complete sentences in one breath, respiratory rate >50 breaths/minute (or >40 in children <5 years), pulse >140 beats/minute, peak expiratory flow <50% predicted, and oxygen saturation <92% 1, 2

Monitoring and Reassessment

• The American Academy of Pediatrics recommends repeating assessment 15-30 minutes after starting treatment, measuring peak expiratory flow before and after each bronchodilator dose, maintaining continuous pulse oximetry with target SpO₂ >92%, and monitoring respiratory rate, heart rate, and work of breathing 1, 2, 4

Escalation for Inadequate Response

• The American Academy of Pediatrics recommends intravenous magnesium sulfate for life-threatening exacerbations or those remaining severe after 1 hour of intensive conventional treatment, with nine guidelines supporting IV magnesium sulfate for severe asthma exacerbations 1, 2, 3

Hospital Admission Criteria

• The American Academy of Pediatrics recommends admitting to hospital if there are persistent features of severe asthma after initial treatment, peak expiratory flow remains <50% predicted 15-30 minutes after treatment, SpO₂ <92% despite treatment, life-threatening features are present, or parents are unable to give appropriate treatment at home 1, 2

Critical Pitfalls to Avoid

• The American Academy of Pediatrics recommends never delaying systemic corticosteroids while giving repeated albuterol doses alone, as failure to respond to initial beta-agonist treatment mandates immediate corticosteroid administration, and underuse of corticosteroids is specifically identified as a leading cause of preventable asthma mortality 2, 4

Discharge Criteria

• The American Academy of Pediatrics recommends discharging children when they have been on discharge medication for 24 hours, peak flow >75% of predicted, SpO₂ stable >92% on room air, treatment plan includes both bronchodilators and inhaled corticosteroid controller therapy, and a written action plan is provided with follow-up arranged within 1 week 1, 2
