Week 6 Paediatrics (Q. 1 & 2) Flashcards
What is the difference between an ‘extrathoracic obstruction’ and an ‘intrathoracic obstruction’?
- The extrathoracic (superior) airway, which includes the supraglottic, glottic, and infraglottic regions
- The intrathoracic (inferior) airway, which includes the trachea, the mainstem bronchi, and multiple bronchial generations (which have as their main function the conduction of air to the alveolar surface)
Upper Respiratory Tract Infections are generally treated with referral to GP and Paracetamol. What some sign and symptoms?
Children experience 6-8 of these a year
Mostly young children as socialisation takes place (daycare)
SxSx
- Runny Nose
- Pharyngitis
- Fever
Rx
- Symptomatic including paracetamol for discomfort
- GP referral
True or False
Viral infections of the tonsils are more common than bacterial infections?
What are Sx and Sx of Tonsilitis and what is the Rx as per paramedics?
A. True
Tonsilitis is usually viral in origin (can be bacterial)
Severe tonsillitis may cause URTI
SxSx
- swelling on tonsils and pharynx
- may have white exudate on tonsils
- Bacterial tonsillitis may cause yellow coloured pus formation over the tonsils
Rx
- Generally viral so antibiotics not required
- Gargles, lozenges and paracetamol

Explain where the obstruction is for Inspiratory and expiratory stridor and snoring?
Inspiratory Stridor = extra thoracic obstruction
Expiratory Stridor = intra thoracic obstruction
Snoring = Nasopharyngeal obstruction

Rx
- Most will resolve spontaneously

- Antibiotics if a bacterial infection
What is Croup and what age bracket does it commonly appear?
Acute Laryngotracheobronchitis
Croup is a Virall inflammation of the
- upper airway,
- larynx,
- trachea and
- bronchi
Common in children 6 months to 6 years
Aetiology
- According to Jacqui’s lecture, 85% of croup presentations are viral
True or False?
Males have a greater risk of Croup than females.
True
Risk Factors
- Late autumn and winter
- Males > females

What is the Rx for Croup as per the Upper Airway Obstruction CPG P0601
Mild
- BLS,
- Rx per severe if Pt deteriorates
Mod
- Dexamethasone 600 mcg/kg Oral (max 12mg)
- Tx
- Rx per severe if Pt deteriorates
Severe
- Adrenaline 5mg (5mL) Nebulised
- Dexamethasone 600 mcg/kg Oral (max 12mg)
- if improved –
- continue to monitor Pt
- Tx
- if unimproved –
- Repeat Adrenaline 5min intervals until improvement
- continue to monitor Pt
- Tx
Paracetamol as per the pain guideline
15mg/kg oral (if not already administered 4/24)
Epiglottitis is a severe, life-threatening and progressive infection of the Epiglottis and surrounding areas.
What is the primary cause of epiglottitis?
A. Haemophilus influenza type B Vaccine
B. Haemophilus influenzae type A
C. Haemophilus Ducreyi
D. Haemophilus Parainfluenzae
Haemophilus influenza type B Vaccine
Children who are not vaccinated have a greater risk of contracting Epiglottitis.
What are the Sx and Sx of epiglottitis?
Hint: NERDS
N - No Cough E - Expiratory Snore R - Rapid Onset D - Drooling and Dysphagia S - Septic and Flushed
Epiglottitis can kill fast
Why do we NOT inspect the airway in patients with suspected epiglottitis?
A. Increases risk of respiratory arrest
B. May spread the infection to other areas
C. Increases anxiety in the patient
D. A and C
D. A and C
Avoid examination of the airway as this may cause laryngospasm and respiratory arrest
Limit anxiety – hands off the sick child
Expedient transport to a paediatric facility
In hospital: intubation in theatre (? surgical airway) and IV antibiotics
Which is not an upper airway disorder?
A. Croup
B. Epiglottitis
C. URTI
D. Bronchiolitis
D. Bronchiolitis
Inflammatory obstruction and necrosis of the cells of the lower airways
What is Respiratory Distress Syndrome?
Poorly developed lung structure and lack of surfactant = RDS
SxSx
- Appears minutes after birth
- Respiratory distress: grunting, ↑ WOB
- Acute pulmonary oedema
- Cyanotic, dusky skin
What is the survival rate of Respiratory Distress Syndrome
A. 5 - 10%
B. 25 - 50%
C. 50 - 70%
D. 60 - 80%
C. 50 - 70%
It is the leading cause of death in newborns - primarily preterm infants
Rx includes:
- Glucocorticoid Administration during labour = enhanced lung maturation
- Mechanical ventilation with PEEP
- Exogenous surfactant administration
Which is not a Treatment for Respiratory Distress Syndrome?
A. Glucocorticoid Administration during labour = enhanced lung maturation
B. Mechanical ventilation with PEEP
C. Exogenous surfactant administration
D. Bronchodilators
D. Bronchodilators
Not a treatment for RDS
Bronchodilators may not actually work due to underdeveloped Beta 2 receptors
Which is true for Pneumonia?
A. Results from shared contact via sex and ulcerative wounds, cuts or menstrual blood
B. Only affects the elderly and paediatrics
C. Requires no in hopsital Rx
D. Bacterial infection more serious than Viral Pneumonia
D. Bacterial infection more serious than Viral Pneumonia
Leading cause of death and illness in young children, elderly and immunosuppressed
Viral is more common than bacterial
Results from inhalation of microbes dispersed in ambient air
What is bronchiolitis?
A. Swelling and inflammation leading to overinflation of the lungs
B. Severe, life-threatening and progressive infection of the epiglottis
C. Eustachian tube dysfunction
D. An acute episode of airway constriction due to a pathogen
A. Swelling and inflammation leading to overinflation of the lungs
Epithelial cells of the respiratory tract become swollen and inflamed –> obstruction –> progression over inflation of the lungs
What is not true regarding bronchiolitis?
A. Most common < 2-year-olds B. Often preceded by URTI C. Bronchodilators are used as an Rx option D. Usually bacterial E. Most common in winter months
D. Usually bacterial
Bronchiolitis usually is a viral infection. Respiratory syncytial virus (RSV) causes more than half of all cases.
How is a Febrile Convulsion different to Epilepsy?
Seizure occurring with fever in infancy or childhood without evidence of other underlying cause
or
sudden change in your child’s body temperature, and is usually associated with a fever
Epilepsy: recurring seizures due to a chronic abnormality in the cerebral cortex
Why do we not give paracetamol for fever?
During fever, a protein called pyrogen is generated. This increases the synthesis of a compound called prostaglandin in the hypothalamus, raising its temperature set point. Paracetamol acts as an antipyretic and inhibits the synthesis of prostaglandin
As a consequence, the lower body temp, reduces the effect of fever –> to increase body temp to kill the pathogen
What is the Midazolam does for a Small Child suffering from Status Epilepticus?
A. 2.5 - 5mg IV
B. 2.5mg IM
C. 1mg IV
