Q

What advice can you give parents about caring for a child with tonsillitis?

A

Bacterial vs. viral (which will get better on its own)

Drink a lot of fluids
Plenty of rest
Serve liquids and soft foods if hard to eat (including ice cream lol)

Keep child’s glasses and utensils separate and wash thoroughly in hot, soapy water

Acetaminophen or ibuprofen for pain relief, NOT aspirin!! (Reye syndrome)

Everyone in the family to wash their hands very often, because very contagious

Q

What treatment is available for otitis media?

A

Analgesia (regular paracetamol or ibuprofen)

Q

What are the characteristics of acute upper airway obstruction?

A

Stridor
Hoarseness of voice due to inflammation of vocal cords

Barking cough
Variable degree of dyspnoea

18
Q

What is the basic management of upper airway obstruction?

A 
DO NOT examine throat!
Reduce anxiety (be calm and confident)

Observe for signs of hypoxia/deterioration.

If severe - nebulised adrenaline

Contact anaesthetist. Resp failure may develop and will need tracheal intubation

19
Q

Which viruses normally cause croup?

A

Parainfluenza virus commonest

Human metapneumovirus
RSV
Influenza

20
Q

What is croup? Aetiology?

A

laryngotracheobronchitis

Mucosal inflammation and increased secretions affecting the airways

21
Q

At which ages does croup occur?

A

6 months to 6 years old

22
Q

Symptoms of croup? Which time of year

A

Commonest in autum
Symptom onset/worsen at night
Should resolve in 48 hours

Barking cough
Harsh stridor
Hoarseness
Preceded by fever and coryza

23
Q

How would parents be advised to care for a child with viral croup?

A

Observe closely for signs of increasing severity - ambulance
(stridor, restless, agitated, intercostal recession)
Cyanosis

If appears distressed due to fever, can give paracetamol/ibuprofen to lower distress (alternate agents if persists)

Encourage regular fluids

Continue breastfeeding

24
Q

Which treatment options are available fo croup?

A

Reduce severity and duration:
Oral dexamethasone (0.15mg/kg)
Oral prednisolone
Nebulised steroids (budesonide)

If severe obstruction:
nebulised adrenaline with oxygen facemask for transient improvement. Close monitoring required (inc anaesthetist) because there may be rebound symptoms after 2 hours

Supplementary oxygen to all children with severe illness

25
Q

What is the causative organism of epiglottitis?

A

HiB

>99% reduction due to vaccine

26
Q

How does acute epiglottitis present? Age group

A

Life-threatening emergency (high risk of resp obstruction)

Swelling of epiglottis and surrounding tissues associated with septicaemia

Usually 1-6year olds

VERY ACUTE:
High fever, ill-looking.
Intensely painful throat (prevents from speaking/swallowing).
Saliva drools down the chin
Soft inspiratory stridor and rapidly increasing respiratory difficulty.
Sitting upright, immobile, with open mouth.

27
Q

How can viral laryngotracheitis (croup) and epiglottitis be distinguished clinically?

A 
CROUP
Onset over days.
Preceding coryza.
Cough - severe, barking.
Able to drink.
No drooling saliva.
Appears unwell and fever <38.5°C.
Stridor harsh and rasping. Voice hoarse.
Epiglottitis:
Onset over hours.
No coryza.
Absent cough/slight.
Unable to drink.
Drooling saliva.
Toxic appearance, very ill.
>38.5°C.
Soft, whispering stridor.
Reluctant to speak.
28
Q

When should a child with fever be taken to the doctor?

A

< 3 months old with >38°C
3-6 months old with >39°C

Or other signs of being unwell: persistent vomiting, refusal to feed, floppiness, or drowsiness
Sometimes even rash, fits/seizures, SOB

29
Q

What treatment is available for fever?

A

Plenty of fluid/milk even if isn’t thirsty.
Appropriately dressed, but eg. thinner sheets

Paracetamol and ibuprofen, but only if DISTRESSED! Never both at the same time. If one does not work, can give the other one later on.

If >41°C, methods such as cooling blankets are indicated

30
Q

What are febrile seizures?

A

Can occur in any child <6 years of age
If no previous afebrile seizures or neurological pathology.
Most last <15 min (simple)

31
Q

What are the physiological consequences of fever?

A

Can cause febrile seizures in children.
Increases stress in cardiac/pulmonary illness due to raising BMR.

> 41°C can cause damage: protein denaturation, cytokines activate inflammatory cascade leading to cellular and organ failure. DIC due to activation of coagulation cascade.

32
Q

What is the pathophysiology of fever?

A

Fever results when something raises the hypothalamic set point, triggering vasoconstriction and shunting of blood from the periphery to decrease heat loss; sometimes shivering, which increases heat production, is induced. These processes continue until the temperature of the blood bathing the hypothalamus reaches the new set point. Resetting the hypothalamic set point downward (eg, with antipyretic drugs) initiates heat loss through sweating and vasodilation.

33
Q

What are the clinical features of bacterial tracheitis?

A

Rare but dangerous. Pseudomembranous croup.
The difference to viral croup is that there is:
High fever
Toxic appearance
Rapidly progressing airway obstruction with copious thick airway secretions.

Loud, harsh stridor

34
Q

What are the differentials for acute upper airway obstruction?

A

Croup most common (coryza and mild fever)
Foreign body (sudden onset cough)
Epiglottitis (painful throat, high fever, toxic)
Bacterial tracheitis (high fever, toxic)
Laryngomalacia or congenital airway abnormality (recurrent)

Allergic laryngeal angioedema 
Infectious mononucleosis 
Measles and diphtheria
Trauma
Retropharyngeal abscess
35
Q

What is the immediate danger posed by burns, scalds and smoke inhalation?

A

Skin thinner, thus burns quicker.
Most deaths caused by house fire are due to smoke inhalation. There is a chance of developing respiratory complications and CO poisoning. There should be a low threshhold to protect the airway.

36
Q

What can be the consequence of a burn to the mouth or face?

A

Face - disfiguring

Mouth - compromise to airway from oedema

37
Q

What is the treatment protocol for burns?

A

Assess: resusc, smoke inhaled? Depth and surface are of burns

Analgesia (may require iv morphine)

IV fluids (plasma expanders)

Wound care (cling film)

Irrigate only for <10% SA burns. Check tetanus immunisation status.

38
Q

Advise parents on how to care for a child with acute otitis media

A

Usually spontaneously resloves within 24h

For pain and fever: paracetamol, change to ibuprofen if persists
Alternate between paracetamol and ibuprofen if still persists

39
Q

Features of bacterial pharyngitis (tonsillitis)

A

CENTOR criteria

Tender cervical lymphadenopathy
Absence of cough
White exudate
Temperature >38°C
Age 3-14
40
Q

Which antibiotics are usually prescribed for severe tonsillitis/pharyngitis?

A

10 day course of penicillin or erythromycin

AVOID amoxicillin, as it may cause widespread maculopapular rash if infection is due to infectious mononucleosis
