Asthma (Adult) Guideline Flashcards
Why are MDIs just as good as nebulisers?
Low resistance and low flow devices which deliver smaller drug particles and achieve greater levels of total lung deposition and penetration into the distal airway tree
What are the mainstay of asthma treatment?
SABAs and SAMAs along with early steroids
What are the 2 key concepts of asthma management?
- bronchodilation and 2. inflammation
What treatment is recommended for severe or life threatening asthma, or a poor response to repeated maximal dose bronchodilators?
- IV magnesium sulphate
Why is a spacer useful?
It decreases the particle velocity and therefore increase deposition in the lung 2. reduces particle impaction on the oropharynx
Why are MDIs and spacers good for clinicians’ safety?
Reduction in nosocomial aerosol contamination
What is the most effective treatment in severe and life threatening asthma?
SABAs and SAMAs via nebuliser are the most effective means of reversing airflow obstruction
Why is Salbutamol chosen as the SABA?
potency, duration of action 4-6 hrs, and B2 selectivity
What is the paramedic treatment for adult in severe asthma?
- high flow oxygen 2. ICP backup 3. SAL 15mg and atrovent 500mcg nebs, repeat PRN 4. Escalate to Life threat if no improvement or deteriorates 5. Transport and notify
What is the paramedic treatment for adult in life treatening asthma?
- high flow oxygen 2. ICP backup 3. SAL continuous and atrovent every 20 mins via neb 4. Fluids 500mL IV 5. Adrenaline 10mcg/kg IM up to 0.5mg, if no response repeat 6. transport and notify
What is the treatment for adult with asthma requiring IPPV?
- continuous nebs 2. ICP backup 3. IPPV with small tidal voumes and slow vent rates 4. fluid bolus 500mL IV 5. Adrenaline 10mcg/kg up to 0.5mg IM, repeat if no response 6. transport and notify
