Q

Which ICS particularly gives bad adverse effects?

A

fluticasone

20
Q

What are 2 important things to remember when using long acting beta agonists?

A
  1. do not use without ICS

2. use as fixed dose inhaler

21
Q

What is the step 4 of treating child asthma?

A

Long acting beta agonist

22
Q

What is the step 5 of treating child asthma?

A

Leukotriene receptor antagonist

23
Q

What is the leukotriene receptor antagonist used in children? (its name)

A

Montelukast

24
Q

In what form does the leukotriene receptor antagonist (LRA), Montelukast appear in for reluctant toddlers?

A

In granules

25
Q

What is the step 6 of treating child asthma?

A

Experimental medicine (only needed for minority with genuine severe disease)

26
Q

When is experimental medicine used? (i.e. what sort of lung issues are needed)

A
  1. 50% physiological

2. > 50% compliance issues

27
Q

What are two types of delivery methods of treatment for asthma in children?

A
  1. MDI/+spacer

2. dry powder device

28
Q

What are the 3 rules for using a spacer?

A
  1. shake inhaler between puffs
  2. wash spacer monthly to reduce static
  3. each increases delivery by 100%
29
Q

What is the lung deposition without a spacer?

A

<5%

30
Q

What is the lung deposition with a spacer?

A

<20% (better lung deposition)

31
Q

What are some of the factors which affect lung deposition? (3)

A
  1. with a not tightly fitting face mask
  2. crying during inhalation
  3. quietly inhaling
32
Q

What age groups use the dry powder devices?

A

licensed in over 5s (under 8s cannot use them)

33
Q

What is the lung deposition in dry powder devices?

A

20%

34
Q

Why are MDI spacers more reliable than nebulisers? (6)

A
  1. quieter
  2. quicker
  3. valve mechanism
  4. don’t break down
  5. portable
  6. cheaper
35
Q

When are nebulisers used in asthmatic patients?

A
  • when high doses of asthma reliever medicines are needed in an emergency
  • turns medication into mist and is easier to deliver as it has a mouthpiece and a facemask
  • not used day-day
36
Q

What are other management techniques for child asthma? (2)

A
  1. stop tobacco smoke exposure

2. remove environmental triggers (e.g. cats or house dust mites)

37
Q

What are the 2 initial steps for treating acute MILD asthma? (starters)

A
  1. SABA via spacer

2. SABA via spacer +prednisolone

38
Q

What are the 2 next steps for treating acute MODERATE asthma? (main course)

A
  1. SABA via nebuliser +prednisolone

2. SABA +ipratropium via nebuliser +prednisolone

39
Q

What are the 5 steps for treating acute SEVERE asthma? (specials)

A
  1. IV salbutamol
  2. IV aminophylline
  3. IV magnesium (nebuliser)
  4. IV hydrocortisone
  5. Intubate and ventilate
40
Q

What are the factors that need to be taken into account for deciding how to treat acute asthma? (7)

A
  1. respiratory rate
  2. work of breathing
  3. heart rate
  4. oxygen saturations
  5. ability to complete sentences
  6. confusion
  7. air entry
41
Q

After treating acute asthma (either mild, moderate or severe), how long should you wait for before reassessing?

A

1 hour

42
Q

What type of steroids are used for chronic/maintenance treatment of asthma?

A

inhaled steroids

43
Q

What type of steroids are used for acute treatment of asthma?

A

oral steroids

44
Q

What are MDIs useless without?

A

spacer

45
Q

There is a different approach to treating asthma in children of what age?

A

under and over 5s
