A
  • throat swab

Q

What mechanism underlies (bacterial) bronchitis?

A
  • the cause isn’t really an infection - reduced mucociliary clearance due to damage by virus or from minor airway malacia
  • infection is secondary

Q

do not treat, reassure and worry if there are red flag symptoms

  • typical history!
30
Q

What is the typical history of bronchiolitis? Learn this as it is useful to be able to tell parents what to expect from the condition depending on when they present.

A

cough start—-3 days later RSV attacks airway and child gets worse to feed—-2 days stable state—2 weeks recovery

31
Q

How should we manage bronchiolitis?

A
  • observe

- no medicines

32
Q

In general, what 4 features characterise a LRTI?

A

-lasting for 48 hours or more
-fever greater than 38.5
-SOB
-cough
wheeze makes bacterial cause unlikely

33
Q

What are common infective agents in LRTI?

A
  • viruses in <35%
  • pneumococcus, mycoplasma, chlamydia
  • mixed infection in <40%
34
Q

When would you call an LRTI, pneumonia?

A

-signs are focal
-crepitations
-high fever
(otherwise just call it an LRTI)

35
Q

What should you do if a child has a community acquired pneumonia?

A
  • nothing and review if symptoms are mild
  • oral amoxycillin (first line) or oral macrolide (second line or in penicillin allergy e.g. clarithromycin)
  • only IV if child is vomiting
36
Q

What is pertussis and what are features of it?

A
  • ‘whooping’ cough
  • very common LRTI
  • child has coughing fits and may vomit at end of it and change colour due to effort
37
Q

What is empyema?

A
  • complication of pneumonia

- spread of infection into pleural space

38
Q

How does empyema present?

A

chest pain and very unwell

39
Q

How would we treat empyema in a child?

A

IV antibiotics with or without drainage

40
Q

What are features of asthma?

A
  • chronic
  • parental asthma
  • wheeze!!!
  • dry nocturnal cough (just after falling asleep), may be exertional too
  • SOB at rest (may see cooking in of ribs with wheeze)
  • variable/reversible!!!!
  • responds to asthma treatment!!!!
  • may be trigger identifiable e.g. URTI, exercise, allergen, cold air, other such as emotion or menstruation
41
Q

What differences are there between asthma in adults and asthma in children?

A
  • gender (affects boys and women)
  • asthma can be severe
  • occupational asthma uncommon
42
Q

What is the suspected aetiology of asthma in children and adults?

A

combination of genetic, environmental and lung function factors e.g. if you had low lung function, high genetic predisposition and smoked then you would be more likely to develop asthma than if you were of low genetic risk, had great lung function and didn’t smoke

43
Q

What is important to consider first in management of asthma in children?

A

watching and waiting if no QOL implications of symptoms

44
Q

What must you have to have asthma and how can you differentiate this from a parent’s history for their child?

A
  • WHEEZE!!!

- can ask if the wheeze sounds more like a rattle or a whistle (can never be a rattle)

45
Q

How can you test whether a child has asthma?

A

if have suspicion do trial dose of ICS for 2 months then do a drug ‘holiday’ to see if the symptoms recur

46
Q

What can be included in a differential diagnosis with asthma?

A
  • viral induced wheeze
  • foreign body, cystic fibrosis, immune deficiency (secretions cause noise)
  • ciliary dyskinesia
  • aspiration
  • tracheo-bronchomalacia
47
Q

What should you do to treat an infrequent episodic wheeze with a cold?

A

salbutamol

48
Q

If there is a child with a preschool moist cough with no associated wheeze and no red flag symptoms, what would you consider the diagnosis to be?

A

bacterial bronchitis

49
Q

If there is a preschool child with a dry cough, no wheeze but has red flag symptoms, what would you consider the diagnosis to be?

A

bronchiectasis

50
Q

What are the goals of treatment of asthma?

A
  • ‘minimal’ symptoms during day and night
  • minimal need for reliever medication
  • no attacks (exacerbations)
  • no limitation of physical activity
51
Q

How can you measure control of asthma?

A

closed questions:SANE:

  • Short acting beta agonist
  • Absence from school/ nursery
  • Nocturnal symptoms
  • Exertional symptoms
52
Q

What is the first step in treatment for asthma?

A

very low dose ICS if greater than 5 years old (orLTRA if <5 years) then review after 2 months

53
Q

If the first step in management is not sufficient what can be done as as second measure?

A
  • if child >5, add inhaled LABA

- if child<5 add LTRA

54
Q

If the second step is not sufficient to managing asthma, what can be done as a third measure?

A

child >5, stop LABA and increase ICS to low level from very low level

55
Q

If the third step is not sufficient in managing asthma, what can be done as a fourth measure?

A

consider trials of:

  • increasing ICS to medium dose
  • addition of SR theophylline
  • refer patient to specialist care
56
Q

If the 4th stage is insufficient is managing asthma, what should be done?

A
  • use daily steroid tablet in lowest dose providing adequate control
  • maintain medium dose ICS
  • consider other treatments to minimise use of steroid tablets
  • refer patient to specialist care
57
Q

What is the maximum dose of ICs for children?

A

800 mcg

58
Q

What else is offered at ALL levels of management for asthma in children?

A

SABA as and when required (the blue inhaler) and must be with a spacer if it is a MDI

59
Q

What are adverse effects of using ICS?

A
  • height suppression (minimal)
  • oral candidiasis
  • adrenocortical suppression
60
Q

What is the only LTRA we use for children?

A

montelukast

61
Q

If a child is having a mild asthma attack, how would you manage it?

A
  • SABA via spacer or

- SABA via spacer and prednisolone

62
Q

If a child is having a moderate asthma attack, what should you do?

A
  • SABA via nebuliser and prednisolone or

- SABA and ipramide nebuliser and prednisolone

63
Q

If a child is having a severe asthma attack or is unresponsive to other treatments, what should you do?

A
  • IV salbutamol
  • IV aminophylline
  • IV magnesium
  • IV hydrocortisone
  • Intubate and ventilate
64
Q

How can you determine the severity of an asthma attack?

A

look at the patient!!!

  • respiratory rate
  • work of breathing
  • heart rate
  • oxygen saturations
  • ability to complete sentences
  • confusion
  • air entry
