Management of Asthma Exacerbation in Children

Initial Assessment and Treatment

For an 11-year-old child with acute asthma exacerbation, immediately administer high-flow oxygen to maintain SpO₂ >92%, 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, oral prednisolone 1-2 mg/kg (maximum 40 mg), and add ipratropium bromide 100-250 mcg to each salbutamol dose for the first hour, as recommended by the Global Initiative for Asthma (GINA) 1
Identify severe exacerbation by clinical features such as being too breathless to talk or complete sentences in one breath, respiratory rate >50 breaths/minute, pulse >140 beats/minute, according to the American Thoracic Society 2
Life-threatening features requiring immediate aggressive intervention include peak flow <33% predicted, silent chest or poor respiratory effort, exhaustion, altered consciousness, or agitation, as stated by the European Respiratory Society 2

Administer high-flow oxygen via face mask immediately to maintain SpO₂ >92% and continue oxygen throughout treatment until SpO₂ remains stable above this threshold, as recommended by the American College of Chest Physicians 1, 2
Salbutamol administration has two equally effective options: nebulized route or MDI with spacer, with the latter resulting in lower admission rates and fewer cardiovascular side effects, according to the European Respiratory Review 1

Administer oral prednisolone 1-2 mg/kg (maximum 40-60 mg) immediately upon recognition of acute severe asthma, as recommended by the Global Initiative for Asthma (GINA) 1
Add ipratropium bromide 100-250 mcg via nebulizer every 20 minutes for 3 doses, then every 6 hours, or 4-8 puffs every 20 minutes for 3 doses via MDI, as stated by the European Respiratory Review 3, 2, 1

Repeat assessment 15-30 minutes after starting treatment, measuring peak expiratory flow, maintaining continuous pulse oximetry, and monitoring respiratory rate, heart rate, and work of breathing, as recommended by the American Thoracic Society 1, 2
Response to initial treatment in the emergency department is a better predictor of hospitalization need than initial severity, according to the Global Initiative for Asthma (GINA) 1

Continue high-flow oxygen, oral prednisolone, and salbutamol as needed, and consider intravenous magnesium sulfate for life-threatening exacerbations, as recommended by the American College of Chest Physicians 1, 2
Admit to hospital if persistent features of severe asthma after initial treatment, peak expiratory flow remains <50% predicted, or SpO₂ <92% despite treatment, as stated by the European Respiratory Society 1, 2

Children can be discharged when on discharge medication for 24 hours, peak flow >75% of predicted, SpO₂ stable >92% on room air, and treatment plan includes both bronchodilators and inhaled corticosteroid controller therapy, as recommended by the Global Initiative for Asthma (GINA) 1, 2, 3
