ASTHMA GUIDELINES Flashcards
adult asthma BTS guidelines
1) low dose ICS
2) +LABA to ICS
3) increase ICS dose / +LTRA
(if no response to LABA - STOP)
4) specialist
child asthma BTS guidelines
1) very low dose ICS
OR LTRA <5yrs
2) >5 = +LABA/LTRA
<5 = +LTRA
3) increase ICS to low rose
or +LABA/LTRA
(if no response to LABA - STOP)
4) specialist
moderate acute asthma
PIN
- PEF >50–75% best or predicted
- increasing symptoms
- no features of acute severe asthma
severe acute asthma
PRSH
- PEF 33–50% best or predicted
- RR ≥25/min
• inability to complete
sentences in one breath
• HR ≥110/min
life threatening asthma
In a patient with severe asthma any one of:
- PEF <33% best or predicted
- SpO₂ <92%
- PaO₂ <8 kPa
- ‘normal’ PaCO₂ (4.6–6.0 kPa)
- altered conscious level
- exhaustion
- arrhythmia
- hypotension
- cyanosis
- silent chest
- poor respiratory effort
management of acute asthma in adults
oxygen
steroid therapy
high dose B2Agonists
Ipratropium 0.5mg 4-6 hourly
Other:
MgSO4 1.2-2g IV over 20mins in patients with acute severe
oxygen aim when treating acute asthma
94-98%
prednisolone dose in acute asthma
40-50mg daily for 5 days
acute severe asthma in children
SpO₂ <92%
PEF 33–50% best or predicted
Can’t complete sentences in one breath
Heart rate
>140/min (1-5 years)
or
>125/min (>5 years)
Respiratory rate
>40/min (1-5 years)
or
>30/min (>5 years)
life threatening asthma in children
SpO₂ <92%
PEF <33% best or predicted
Exhaustion Hypotension Cyanosis Silent chest Poor respiratory effort Confusion
treating acute asthma in children over 1
B2Ag - discontinue any LABA
+ipratropium 250mcg
+150mg MgSO4 in first hour in children with spO2 <92%
steroid therapy in child < 2
10mg 3 days
steroid therapy in child 2-5
20mg 3 days
steroid therapy in child >5
30-40mg 3 days
asthma NICE guidelines >17yo
1) SABA
2) +low dose ICS
3) +LTRA and review in 4-8 weeks
4) +LABA and assess need for LTRA
5) consider MART
6) Increase ICS to high maintenance dose / trial LAMA/theophylline / specialist
