ENT exam - this should never be carried out in patients with upper airway obstruction as this may make it a lot worse

  • Hoarse cough
  • Hoarse voice
  • Drooling
21
Q

How do we manage patients with bacterial tracheitis?

A

Emergency airway management

22
Q

What are the prodromal signs of viral croup?

A

12-48 hour history of;

  • non-specific cough
  • rhinorrhoea
  • fever
23
Q

What should all children who are admitted with mild, moderate or severe croup receive?

A

A stat, single dose of oral dexamethasone (0.15mg/kg)

24
Q

How long does viral croup usually take to self-limit?

A

48 hours

25
Q

What signs do we see in mild croup?

A
  • Seal-like barking cough
  • No stridor
  • No intercostal recession at rest
26
Q

What signs do we see in moderate croup?

A
  • Seal-like barking cough
  • Stridor
  • Sternal recession
27
Q

What signs do we see in severe croup?

A
  • Seal-like barking cough
  • Stridor
  • Intercostal/sternal recession
  • Agitation or lethargy
28
Q

What can we give nebulised to children with moderate or severe croup?

A

Adrenaline 5ml 1:1000

29
Q

What does the term ‘anaphylaxis’ describe?

A
  • Hypotension
  • Bronchoconstriction
  • Airway compromise
30
Q

When assessing a child for risk of future anaphylaxis, what questions must we ask?

A
  1. Does your child have asthma?
  2. If yes, what treatment do they take?
  3. Do they take a regular preventer inhaler?
  4. When they had their initial reaction, how much of the foodstuff or allergen had they been in contact with?
31
Q

What is a major risk factor for anaphylaxis?

A

Poorly controlled asthma

32
Q

What type of hypersensitivity is a food allergy?

A

Type I

33
Q

How does sensitisation occur and what are the underlying physiological mechanisms involved?

A

Following exposure to an antigen the protein causes cross binding of two bound IgE molecules on the Mast Cell or Basophil surface.
This process results in degranulation of the Mast Cell.

34
Q

After a Type I hypersensitivity reaction, which immune mediator is released immediately?

A

Histamine - it is released after mast cell degranulation

35
Q

What are the actions of histamine;

a. Vasodilation
b. Localised irritation
c. Endothelial separation
d. Vasoconstriction
e. Bronchoconstriction
f. Bronchodilation

A

a, b, c, e

36
Q

What is the criteria for prescription of an adrenaline pen?

A
  • Hx of anaphylaxis
  • Previous cardiovascular/respiratory involvement
  • Evidence of airway obstruction
  • Poorly controlled asthma, requiring regular ICS
  • Reaction to a small amount of allergen
  • Ease of allergen avoidance
37
Q

When a newborn/infant changes their feeding habits, what questions would you like to ask mum/dad/guardians?

A
  • How much milk would they normally taken and how much are they taking now?
  • How quickly has their decline in milk intake occurred?
  • Establish why mum/dad/guardian think they stop feeding ; this can give us a lot of insight
  • Explore any sleepiness as this is a VERY worrying sign
  • Ask mum/dad/guardian their thoughts on what is happening
38
Q

How do we assess feeding in newborns/infants?

A

mls/kg/day

39
Q

What is the minimum milk requirement to provide enough calories to grow in newborns up to 1 month old?

A

150mls/kg/day

40
Q

What is the minimum milk requirement to provide enough calories to grow in newborns over 1 month old?

A

100mls/kg/day as long as they are gaining weight

41
Q

What is important information to gather about an infants PMHx?

A

The antenatal history - this accounts for a large portion of their development!!

  • Maternal health - any infections, bleeding, conditions?
  • Delivery - PPROM? PROM? NVD? LSCS?
  • Gestation
  • BW
  • Post delivery - NICU? Any abnormalities?
42
Q

What is the Westley-Croup score?

A

A tool used in assessing the severity of a Childs croup. This should only be used in conjunction with clinical assessment.

43
Q

What is the maximum score on a Westley-Croup score?

A

17

44
Q

At what score do we class a child as having ‘life-threatening croup’?

A

> 6

45
Q

When a child presents with wheeze, why is it important to determine if the child is asthmatic or not?

A

This will help guide management. Asthmatic children will be given steroids (commonly dexamethasone) to help with their asthmatic exacerbation and reduce inflammation. This should not be a management plan for non-asthmatic patients.

46
Q

List causes for newborn/childhood tachycardia

A
  1. Upset/distressed
  2. Pyrexia
  3. Pain
  4. Fear
  5. Cardia arrhythmia e.g. SVT
  6. Increase work - similar to exercise
  7. Cardiac/circulatory failure
  8. Shock (due to injury)
  9. Shock, commonly hypovolaemic
  10. Endocrine e.g. hyperthyroid
47
Q

Give 4 reasons why a baby can be increasingly sleepy.

A
  1. Hypoglycaemic due to poor feeding
  2. Exhausted due to IWOB
  3. Encephalopathic due to infection both viral and bacterial
  4. Encephalopathic due to high ammonia secondary to a metabolic condition
  5. Neurological secondary to head injury
  6. Kernicterus due to increased bilirubin
  7. Hypoxia
48
Q

When is foreign body aspiration most common?

A

Between 6 months and 3 years
