Pharmaceutical Care of Respiratory Patients hospital 2 Flashcards
list some diseases that may be affected by drugs used in asthma/COPD or diseases that may affect drugs.
1) Diabetes
2) Cardiovascular disease (watch potassium)
3) Hypertension
4) Prostatic hyperplasia
5) Glaucoma
6) Liver disease, pneumonia, heart failure – reduce theophylline clearance
list some symptoms of Severe Acute asthma
1) Severe breath-lessness
2) Tachypnea (abnormally rapid breathing)
3) Tachycardia
4) Silent chest
5) Cyanosis
6) Accessory muscle use
7) Altered conscious-ness
8) Decreased O2 saturations
list some Drug-drug Interactions in Asthma/COPD
1) Patients already on theophylline – careful with aminophylline infusions
2) Drugs that lower potassium
3) Theophylline interactions e.g. Lithium, macrolides
outline how you would treat the symptoms of Severe Acute asthma
1) Oxygen to maintain SpO2 94-98%
2) β2 agonist bronchodilators
3) Steroids
4) Ipratropium Bromide
5) Magnesium sulphate
6) Aminophylline
7) Leukotriene Receptor Antagonists/Antibiotics- Not indicated in acute asthma
describe how you would use a β2 agonist bronchodilator for the treatment of severe Acute asthma
1) high doses act quickly to relieve bronchospasm with few side effects – salbutamol 2.5mg – 5mg can be given “back to back”
2) Can also use repeated doses of inhaler via spacer
3) nebulised route (oxygen-driven)
4) Repeat at 15-30 minute intervals
5) Can be given IV
outline the use of Steroids for the treatment of sever acute asthma
1) Prednisolone 40-50mg for at least 5 days
2) Reduce mortality, relapses, subsequent hospital admission and requirement for β2agonist therapy
3) Earlier they are given, better the outcome
4) Steroid tablets are as effective as injected steroids, provided they can be swallowed and retained
outline the use of Ipratropium Bromide for the treatment of sever acute asthma
1) Greater bronchodilation than a β2agonist alone, leading to a faster recovery and shorter duration of admission
2) 500 micrograms every 4-6 hours (usually QDS)
outline the use of Magnesium sulphate for the treatment of sever acute asthma
1) Bronchodilator when given IV or nebulised
2) 1.2-2g iv infusion over 20 minutes
outline the use of Aminophylline for the treatment of sever acute asthma
1) Some patients with near-fatal asthma or life threatening asthma with a poor response to initial therapy may gain additional benefit from IV aminophylline
2) Check levels if taking oral theophylline
what parameters would need to be monitored for an Asthma patient
1) PEFR- peak expiratory flow rate (PEFR)
2) Oxygen saturation
3) Heart rate
4) Potassium
5) Blood glucose
6) Serum theophylline
what promotional health advice should asthma patients be provided with?
1) Patient should be followed-up and reviewed as soon as possible by their asthma nurse
2) Asthma action plan (PAAP) written/reviewed
3) Other lifestyle advice- e.g. pneumococcal vaccine
discuss the counselling advice you would provide to acute asthma patients
1) Assess the exacerbation: trigger factors
2) Optimize treatment:
- compliance and review inhaler technique.
- Consider stepping-up treatment
3) Review self-management education and written action plan:
- Review understanding of how to recognize an exacerbation and what to do
who provides the guidance for the treatment of asthma?
1) Guidance from the British Thoracic Society and Scottish Intercollegiate Guidelines Network (BTS/SIGN)
- Stepwise approach.
- Personalised asthma action plan (PAAP)
- Self-management and inhaler technique
with regards to the step wise approach for the management of asthma, what happens at step one
mild intermediate asthma: Inhaled short-acting beta-2 agonists e.g. salbutamol, terbutaline
with regards to the step wise approach for the management of asthma, what happens at step two
regular preventer therapy: Inhaled corticosteroids (ICS) e.g. beclometasone, fluticasone
