Immediate treatment of acute asthma in children 6–11 in primary care

All of:

Can walk, speak whole sentences in one breath (younger children can speak in phrases)

SpO₂ (room air) >94%

Any of:

Unable to complete sentences in one breath due to breathlessness

Use of accessory muscles of neck or intercostal muscles/tracheal tug/subcostal recession during inspiration

Obvious respiratory distress

SpO₂ (room air) ≤94%

Any of:

Reduced consciousness/collapse, exhaustion

Cyanosis

Poor respiratory effort

SpO₂ (room air) <90%

Poor respiratory effort, soft/absent breath sounds

Immediate treatment

Give salbutamol 4–12 actuations (100 microg per actuation) via pMDI and spacer (tidal breathing)

Repeat salbutamol 4–12 actuations every 20–30 minutes for the first hour, if needed (sooner if needed)

Arrange transfer to acute care

Give salbutamol 12 actuations (100 microg per actuation) via pMDI and spacer (tidal breathing), with mask if needed

If patient cannot breathe through spacer, give 5 mg nebule via nebuliser

Start oxygen supplementation if SpO₂ <92%. Titrate to target SpO₂ 92–96%

Repeat salbutamol 12 actuations at least every 20 minutes for first hour (3 doses)

Arrange transfer to acute care

Give salbutamol 2 x 5 mg nebules via continuous nebulisation driven by oxygen

Maintain SpO₂ to target 92–96%
