Salbutamol and Salbutamol Nebulizer Use in Asthma and COPD

Acute Severe Asthma Management

The British Thoracic Society recommends that adults with acute severe asthma should receive nebulized salbutamol 5 mg (or terbutaline 10 mg) plus oxygen plus oral steroids 1
The British Thoracic Society suggests that nebulized salbutamol 5 mg should be repeated every 4-6 hours if improving, and ipratropium bromide 500 μg should be added if not improving 1
For children with acute severe asthma, the British Thoracic Society recommends nebulized salbutamol 5 mg (or 0.15 mg/kg) or terbutaline 10 mg (or 0.3 mg/kg), repeated 1-4 hourly if improving 1

The Global Initiative for Chronic Obstructive Lung Disease recommends using nebulized salbutamol 2.5-5 mg combined with ipratropium bromide 250-500 μg, given 4-6 hourly for 24-48 hours or until clinical improvement 2
Combination bronchodilator therapy is superior to single-agent therapy, especially in severe cases, according to the Global Initiative for Chronic Obstructive Lung Disease 2

The American Thoracic Society advises that nebulizers should always be driven with air, not oxygen, in patients with carbon dioxide retention and acidosis to prevent worsening hypercapnia 2
The American Thoracic Society recommends providing supplemental oxygen via nasal cannulae at 4 L/min during air-driven nebulization if needed 1, 2

The National Asthma Education and Prevention Program recommends that MDIs with spacers are the first-line option, providing effective bronchodilation with fewer side effects than nebulizers 2
The National Asthma Education and Prevention Program suggests using salbutamol 200-400 μg or terbutaline 500-1000 μg up to four times daily via MDI 2

The American Association for Respiratory Care recommends that patients should sit upright during nebulization for optimal delivery 3
The American Association for Respiratory Care advises using 2.0-4.5 mL volume of fluid in the nebulizer chamber 3
The British Thoracic Society recommends that the first treatment should always be done under supervision 1

The American Thoracic Society warns that water should never be used for nebulization as it may cause bronchoconstriction 2
The American Thoracic Society advises against routinely using oxygen to drive nebulizers in COPD patients due to CO2 retention risk 2
The British Thoracic Society recommends considering using a mouthpiece when administering ipratropium to prevent worsening in glaucoma patients 1
The National Asthma Education and Prevention Program emphasizes that proper inhaler technique must be demonstrated and checked periodically before changing treatments 2
