Q

What is the managment of Asthma in children in an Outpatient Setting?

A

(1) SABA :
Salbutamol PRN (consider stepping up when using inhaler ≥3x a week)
* Can use a spacer if young or difficulty using
Acute dose = 1 puff per 30-60s (≤10 puffs) – 5 tidal breaths / puff
Normal dose = do not exceed 4-hourly puffs (i.e. 4 puffs a day)

(2) ICS: Low dose inhaled corticosteroid
E.G. Becotide (BECLOMETASONE DIPROPIONATE)

(3) **2-16yo LTRA ** Leukotriene Receptor Antagonist (Oral Montelukast),
review 4-8w
* 5-16yo; if fail on review, switch LTRA to LABA
* <5yo; if fail on review, stop LTRA and refer to **specialist **

(4)** ICS increased dose** Larger dose ICS; consider reducing dose once asthma controlled
E.G. Flixotide (FLUTICASONE PROPRIONATE)

(5)** Oral steroid ** Lowest dose to maintain control (prednisolone), managed by specialist
Used in any severity exacerbation of asthma for 3-5 days

Q

What is the appropriate management of Asthma in a hospital setting?

A

Admit those of SEVERE or LIFE-THREATENING classification

  1. Burst step (if wheezy and hx of atopy) – give all the below: +** O2 therapy** (maintain SpO2 >92%)
    3x salbutamol nebs (or up to 10 inhales on a pump) SE (of too much) = shivering, vomiting
    2x ipratropium bromide (Atrovent) nebulisers
    1x oral Prednisolone (benefit after 4-6h) – ONLY USED IN ASTHMA (general hypoxia does not use this)

Involve seniors after burst therapy has failed to work

2. IV bolus step – give one of the below:
**1st –> IV bolus MgSO4 **
IV bolus Salbutamol Monitor ECG
IV bolus Aminophylline Monitor ECG, infuse slow (arrhythmias)
If “2<age<5”, consider montelukast

3.** IV infusion step** – give one of the below:
IV Salbutamol
IV Aminophylline

4. Panic step
Intubate and ventilate if classified as life threatening
Transfer to ICU

After patient has stabilised… give salbutamol 1-hourly–> 2-hourly –> 3-hourly –> 4-hourly –> home when…
**Stable on 4-hourly treatment **(can then wean further when at home)
Peak flow at 75% of best predicted
SpO2 >94%

Follow-up within 2 days of discharge / leaving A&E

Q

What is the appropriate managment of Sinusitis?

A
  1. Proper Education of patients:
  2. most likely a virus, it needs to run its course
  3. Just because something is aleviating a symptoms it does not mean that it is shortenting the course of the illness

Symptoms lasting <10 days:
1. No antibiotic
2. Advice – virus, takes 2-3 weeks to resolve, only 2% get bacterial complication, simple analgesia
* Some people may find some relief using nasal saline or nasal decongestants
* Medical advice if symptoms worsen rapidly, do not improve in 3w, systemically unwell

Symptoms lasting >10 days:
1. High-dose nasal corticosteroid for 14 days (if >12yo; e.g. mometasone)
* May improve symptoms but unlikely to affect duration of illness
* Could cause systemic side-effects
ABx not indicated (as per guidelines) but can give back up prescription
* 1st line: phenoxymethylpenicillin (clarithromycin if penicillin-allergic)
* 2nd line: co-amoxiclav

* Genetic tests

CXR (hyperinflation, peri-bronchial shadowing, bronchial wall thickening, ring shadows)

35
Q

What is the management of CF?

A

Respiratory:

(1) Increased monitoring with spirometry and symptoms watches

(2) Physiotherapy twice a day → airway clearance manoeuvres and devices + encourage physical activity

(3) Mucolytic therapy:
* 1st line: rhDNase
If too young to tolerate, use mannitol dry powder (INH)
* 2nd line: rhDNase + hypertonic saline

Infection:

  1. Prophylaxis oral antibiotics (flucloxacillin and azithromycin to reduce exacerbation chance)
  2. **Rescue packs **(for prompt IV ABx with any symptoms or signs of infection)
  3. If end stage CF lung disease – transplant is the only option
  4. Minimise contact with other CF sufferers

Nutrition:
1. High calorie + high fat diet (150% of normal) + fat-soluble vitamin supplements
2. Pancreatic enzyme replacement (with every meal)  CREON ©

Pshychological

Liver problems (i.e. cirrhosis, portal HTN) may ultimately require transplantation
Ursodeoxycholic acid therapy (improve bile flow)

36
Q

What is Laryngomalacia and at which age is it more common?

A

Congenital Abnormality of the Larynx where the epiglotis obstructs the way during breathing

Symptoms peak at 2-6 weeks old

Usually resolves by 18-24 months

37

What are the Signs and Symptoms of Laryngomalacia?

A

Stridor during inspiration, worse when supine, feeding or agitated
GORD symptoms
Normal Cry

38
Q

What is the management of Laryngomalacia?

A

Conservative (close observation and monitoring of growth)–> resolve by 18-24 months (70% by 1-year-old)

May initially worsen with age, max at 6-8 months

Complications: respiratory distress, failure to thrive, cyanosis

Endoscopic supraglottoplasty if airway compromise or feeding disrupted sufficiently to prevent normal growth

39
Q

What are the commonest causes of Pneumonia in younger and older children?

A

Younger: Usually viral

  1. Neonates: GBS from mother’s genital tracts
  2. Infants: RSV, S. pneumoniae, H. influenzae, Bordetella pertussis, C. trachomatis, S. aureus

Older: usually bacterial

> 5yo = M. pneumoniae, S. pneumoniae, Chlamydia pneumoniae

All ages = Mycobacterium tuberculosis should be considered

40
Q

How to differentiate Pneumonia from Bronchiolitis on Ascultation?

A

bronchiolitis = fine crackles; pneumonia = coarse crackles

41
Q

What is the appropriate management of Pneumonia, when should you admit?

A

Hospital admission if…
(this is the same for any respiratory condition)

  1. SpO2 <92% on air
  2. Grunting
  3. Marked chest recession
  4. RR >60/min (severe tachypnoea)
  5. Cyanosis
  6. T >38C
  7. Child <3months
  8. Low feeding
  9. Low consciousness

Whilst awaiting hospital admission–> supplemental oxygen if SpO2 <92%

Antibiotics (cannot distinguish viral from bacterial, so give anyway):

Child <2yo with mild LRTI–> do not have pneumonia usually (so, no ABx)

1st line / mild CAP = amoxicillin, 7-14 days

2nd line / severe CAP = Co-amoxiclav + macrolides (clarithromycin)

Alternative = cefaclor

Macrolides for pen-allergic patients (i.e. clarithromycin)

In pneumonia associated with influenzae, co-amoxiclav is recommended

42
Q

What is the management of Tuberculosis?

A

Ix: manteaux test (if -ve, excludes) –> IGRA test (if -ve, prophylaxis; if +ve, treat)

  • Manteaux >5mm = +ve in immunodeficiency
  • Manteaux >10mm = +ve in at-risk groups (child <4yo, healthcare workers, IVDU)
  • Manteaux >15mm = +ve in normal population

Mx: RIPE, RiCES or prophylaxis:

  • (MTB) RIPE = 6m Rifampicin, 6m Isoniazid, 2m Pyrazinamide, 2m Ethambutol
    • (NTM) RiCES = Rifampicin, Clarithromycin, Ethambutol ± Streptomycin/amikacin
  • Prophylaxis = isoniazid
43
Q

What can cause Chronic Lung Disease (CLD) to an newborn/babie?

A

AKA: Bronchopulmonary dysplasia

  1. Delay in lung maturation (i.e. premature)
  2. Pressure and volume trauma from artificial ventilation
  3. Oxygen toxicity
  4. Infection
44
Q

A

Widspread opacification

45
Q

What is the management of CLD/Bronchopulmomary Dsiplasia?

A

Artificial ventilation [bad CLD]

CPAP or high-flow nasal cannula [normal CLD]

Corticosteroids (low-dose, short course; fear of abnormal development) –> induce earlier weaning

46
Q

Which organisms causes Whooping Cough?

A

Gram negative bacterial, Bordetella pertussis

47
Q

What are the signs and Symptoms of Whooping Cough?

A

1-week coryzal symptoms (catarrhal phase) followed by…

Continuous coughing followed by inspiratory whoop ± vomiting ± epistaxis ± conjunctival haemorrhages

Child = worst at night, may go red/blue

Infants = apnoea rather than a whoop

48
Q

Which investigations for Whooping cough?

A

Culture ± PCR NPA (Naso-Pharyngeal Aspirate – i.e. nasal swab) for Bordetella pertussis

Notify HPU

49
Q

What is the appropriate management for Whooping cough?

A

Admit (and isolate on ward) if
<6mo or acutely unwell:

Treatment
(if admission is not needed, prescribe an antibiotic if the onset of the cough is within 21 days):
<1 month = oral clarithromycin
1+ months = oral azithromycin
2nd line = co-amoxiclav (if macrolides are contra-indicated; not in pregnant adults or babies <6w)

Advice:
1. Rest, fluids, paracetamol or ibuprofen
2. Educate parents – disease is likely to cause a protracted non-infectious cough (may take weeks to resolve fully); complete any outstanding immunisations;
3. Close contacts prophylaxis macrolides
4. Avoid nursery until 48 hours of antibiotics or until 21 days after the onset of the cough if not treated
