Adult Asthma Management Flashcards
What investigations can be carried out in the diagnosis of asthma?
- Peak flow monitoring
- Spirometry
- Bronchodilator reversibility
- Blood tests
- Allergy tests
- Bronchia; hyper-responsiveness
- Exhaled NO
- CXR in some patients
- Challenge testing
What is occupational asthma?
- Symptoms related to work exposure
- No prior history of asthma
What is work exacerbated asthma?
- Symptoms related to work exposure
- Prior history of asthma
What non-pharmacological management is there for acute asthma attack?
- ITU/HDU
- Ventilation
- ECCO2R
- Chest drain if pneumothorax
What non-pharmacological management is there for chronic asthma?
- Asthma action plan
- Weight loss if high BMI
- Vaccines
- Allergen avoidance
- Physiotherapy
- Smoking cessation
- Bronchial thermoplasty
What drugs should be avoided in asthma?
- Beta blockers
- NSAIDs/aspirin
- Sedatives/ strong opiates unless in critical care
What bronchodilators are used in asthma management?
- B2 agonists (b)
- Anti-muscarinincs (b)
- Theophyllines (b)
- Magnesium (a)
What anti-inflammatories are used in asthma management?
- Steroids (b)
- Leukotriene RAs (c)
- Monoclonal Abs (c)
Why are inhalers used in chronic asthma management?
- Small doses
- Delivery directly to the target organ
- Onset of effect is faster
- Minimal systemic exposure
- Systemic adverse effects are less severe and less frequent
Describe the use of pMDI.
- Needs co-ordination
- Elderly, young children and the unwell can’t use effectively
- Generates aerosol: low inspiratory flow
What are the advantages of using pMDI with a spacer?
- Low oro-pharnygeal deposition of aerosol
- Reduced speed of the aerosol
- Decreases bad taste associated with oral deposition
- Reduced the risk of oral candidiasis and dysphonia with steroids
- Reduced cold-Freon effect in some
Describe the use of DPI.
- Patient generates aerosol: high inspiratory flow
- Less coordination required
- Similar issues with deposition
What is complete control of asthma defined as?
- No daytime symptoms
- No night time awakening due to asthma
- No need for rescue medication
- No asthma attacks
- No limitation on activity and normal lung function
- Minimal side effects
What forms do SABA relievers come in?
- Salbutamol as MDI or DPI
- Terbutaline as DPI
What are the adverse effects of oral B2 agonists?
- Tremor
- Cramp
- Headache
- Flushing
- Palpitations
- Angina
What ICS preventers are there?
- Beclomethasone
- Budesonide
- Fluticasone
- Ciclesonide
- Mometasone
