17
Q

What are the three options for adding on preventer?

A
  • Add on LABA
  • Add on LTRA
  • Increase ICS dose
18
Q

What should you do in under 5 patients before prescribing high dose therapies?

A

Refer for confirmation of diagnosis

19
Q

WHat should you do when prescribing continuous or regular oral steroids?

A

REFER!

20
Q

Why are inhaled corticosteroids fab?

A
  • Very useful for diagnosis
  • Very effective (when taken)
  • Very safe (when prescribed correctly) (Large therapeutic range – unlikely to cause harm)
21
Q

What is the general trend in dose response for ICS?

A

Large increase in positive effects for the initial dose of steroids - the rate of increase of positive effects gradually decreases as the dose increases.

22
Q

How do the adverse effects of ICS compare?

A
23
Q

What are the adverse effects of ICS?

A

Height suppression (1cm)

Oral candidiasis?

Adrenocortical suppression?

24
Q

What are the two things to remember about a long acting beta agonist?

A

Do not use without ICS - you can die in you use them on their own

Use as fixed dose inhaler

25
Q

What are the benefits of having a combination inhaler of LABA and ICS?

A

Better compliance as well as potential synergy between the two chemicals

26
Q

What is step 4?

A

Additional add on therapies

27
Q

What is step 5?

Q

What are the treatments for mild acute asthma?

A

SABA via spacer

SABA via spacer and prednisolone

36
Q

What is the treatment for patients for moderate acute asthma?

A

SABA via nebuliser + prednisolone

SABA and ipratropium via nebuliser and prednisolone

37
Q

What are the treatments for patients with severe acute asthma?

A

IV salbutamol

IV aminophyline

IV magnesium

IV hydrocortisone

Intubate and Ventilate

38
Q

How do you make the differential dagnosis between mild, moderate and severe acute asthma treatments?

A

Look at the following features of the patient:

  • Repiratory rate
  • Work of breathing
  • Heart rate
  • Oxygen saturations
  • Ability to complete sentences
  • Confusion - related to hypoxia
  • Air entry
39
Q

What is a measure of work of breathing between children and adults?

A

Subcostal recession in children

Adults - use of accessory muscles

40
Q
