Child health 3 Flashcards
Bacteraemia vs septicaemia
> bacteraemia = presence of bacteria in the BS
septicaemia = presence of pathogens in the BS -> sepsis
Diagnosing infections
> urine
blood tests & culture
CXR
lumbar puncture for CSF
resp secretions
swabs
Croup
> viral
hoarse voice
barking cough
resp distress
Epiglottis
> Bacterial
child looks septic, drooling, soft stridor
avoid examining
call for senior help
chemoprophylaxis
> refers to the administration of a medication for the purpose
of preventing disease or infection
When should vaccines be avoided
during febrile illness
absolute CI to vaccines
> Absolute CI: severe local or generalised reaction previously
Not given when on systemic steroids or immunosupression
Gap between ig and live vaccine administration
12 week gap between human immunoglobulin and live vaccine administration
vaccines: egg allergy
influenza, yellow fever, hepatitis A
What could be causing a pyrexia of unknown origin
> Infectious diseases – bacterial, viral, fungal, parasitic
Connective tissue disorders
Malignancy
Miscellaneous
• Drug fever
• Inflammatory bowel disease
• Sarcoidosis
Kawasaki disease
> fever lasting 5+ days without any other cause
at least 4 out of 5:
• Bilateral non-purulent conjunctivitis
• Polymorphous rash
• Cervical lymphadenopathy
• Peripheral peeling / oedema / erythema
• Oral mucous membrane changes
Causes of stridor in children
> Croup
acute epiglottis
laryngomalacia
inhaled foreign body
Features of inhaled foreign body
> Features are of sudden onset
coughing
choking
vomiting
stridor
Laryngomalacia
> Congenital abnormality of the larynx.
Infants typical present at 4 weeks of age with:
stridor
What is croup
> upper resp TI seen in infants and toddlers
stridor from laryngeal oedema and secretions
caused by parainfluenza viruses
more common in autumn
CF of croup
> cough - barking, worse at night
stridor (do not examine throat at the risk of prec airway obstruction)
fever
coryzal symptoms
inc work of breathing e.g. retraction
Grading severity of croup
> Image
Ix for croup
> Most diagnosed clinically
if a CXR is done:
PA view will show subglottic narrowing - steeple sign
lateral view will show swelling of the epiglottis - thumb sign
Mx of croup
> single dose of dexamethasone to all kids regardless of severity
predinsolone is the alt
Emergency Tx of croup
> high-flow oxygen
nebulised adrenaline
Epiglottitis
> caused by haemophilus influenza type B -> swelling can completely occlude airways -> life threatening
children vaccinated against haemophilus (higher risk in unvaccinated kids)
Presentation of epiglottitis in exams
> unvaccinated child presenting with a fever, sore throat, difficulty swallowing that is sitting forward and drooling and suspect epiglottitis.
Presentation Suggesting Possible Epiglottitis
> Patient presenting with a sore throat and stridor
Drooling
Tripod position, sat forward with a hand on each knee
High fever
Difficulty or painful swallowing
Muffled voice
Scared and quiet child
Septic and unwell appearance
investigations for epiglottitis
> if ppt acutely unwell then do not perform Ix
XR of neck shows thumb sign - soft tissue shadow that looks like a thumb pressed into the trachea.
Mx of eoglottitis
> do not distress the child
prepare to intubate
once airway is secure:
IV antibiotics (e.g. ceftriaxone)
Steroids (i.e. dexamethasone)
Common complication of epiglottitis
A common complication to be aware of is the development of an epiglottic abscess, which is a collection of pus around the epiglottis. This also threatens the airway, making it a life threatening emergency. Treatment is similar to epiglottitis.
Mx of mild croup at home
> Symptoms usually resolve within 48 hours, although some episodes may last for up to one week.
Parents/carers should be advised to give paracetamol or ibuprofen to control fever and pain and to seek urgent medical advice if there is any deterioration.
Hospital admission may be required in some cases, for example if there is chronic lung disease, congenital heart disease, immunodeficiency, respiratory rate of over 60 breaths/minute, high fever, or inadequate fluid intake.
croup - what is an indicatio for admission
Croup: audible stridor at rest is an indication for admission

Mx of acute limp for kids
Urgent assessment should be arranged for a child < 3 years presenting with an acute limp - NICE guidance states transient synovitis is rare in this age group and septic arthritis more common - an urgent specialist assessment is therefore indicated for a child < 3 years with an acute limp.
