Beta 2 Agonist Salbutamol PLUS Ipratroprium via nebuliser (preferably O2 driven)

Salbutamol 5mg

Ipratroprium 0.5 mg

If tolerating prednisilone 40 - 50 mg orally

Q

Management of acute asthma attack in child > 5 yrs

A

B2 bronchodilator plus ipratroprium:

Nebuliser salbutamol 5 mg and ipratroprium 0.25 mg every 20 minutes

OR if nebs and ipratrorium not available give B2 agonist via spacer (1 puff given at a time, inhaled by tidal breathing, give next puff after 60 seconds up to max 10 puffs)

Oral prednisilone 30-40 mg
