BACKGROUND: Acute asthma exacerbations remain a common cause of hospitalisation and healthcare utilisation in South African children. AIM: To update the South African paediatric acute asthma guidelines according to current evidence, and produce separate recommendations for children above and below 2 years of age. METHODS: A working group of the South African Childhood Asthma Group was established to review the published literature on acute asthma in children from 2000 to 2012, and to revise the South African guidelines accordingly. RECOMMENDATIONS: Short-acting inhaled bronchodilators remain the first-line treatment of acute asthma. A metered dose inhaler with spacer is preferable to nebulisation for bronchodilator therapy to treat mild to moderate asthma. Two to four puffs of a short-acting bronchodilator given every 20 - 30 minutes, depending on clinical response, should be given for mild attacks; up to 10 puffs may be needed for more severe asthma. Children with severe asthma or oxygen saturation (SpO₂) <92% should receive oxygen and frequent doses of nebulised β₂-agonists, and be referred to hospital. Nebulised ipratropium bromide (via nebulisation or multidosing via pMDI-spacer combination) should be added if there is a poor response to three doses of β₂-agonist or if the symptoms are severe. Early use of corticosteroids reduces the need for hospital admission and prevents relapse; oral therapy is preferable. Assessment of acute asthma in children below the age of 2 years can be difficult, and other causes of wheezing must be excluded. Treatment of acute asthma in this age group is similar to that of older children. CONCLUSION: Effective therapy for treatment of acute asthma - primarily inhaled short-acting β₂-agonists, oral corticosteroids and oxygen with appropriate delivery systems - should be available in all healthcare facilities and rapidly instituted for treatment of acute asthma in children. ENDORSEMENT: The guideline document is endorsed by the Allergy Society of South Africa (ALLSA), the South African Thoracic Society (SATS), the National Asthma Education Programme (NAEP), the South African Paediatric Association (SAPA) and the South African Academy of Family Practice.
