Childhood Asthma & Wheeze Nursing

GCC Context — BTS/GINA Evidence-Based Clinical Reference | Paediatric Nursing Competency Guide

📍 GCC Prevalence

Saudi Arabia

  • 10–20% of children affected — rising trend
  • Urbanisation, air conditioning, indoor allergens
  • Dust storms (haboob) — particulate matter trigger
  • Higher rates in cities vs rural areas

Regional Factors

  • UAE coastal: high humidity — mould, dust mite burden
  • Qatar/Kuwait: desert dust + industrial emissions
  • Oman: frankincense burning — indoor smoke exposure
  • Shisha prevalence — passive smoke in children
Key point: Asthma is under-diagnosed in GCC — cultural reluctance, symptom normalisation ("just a cough"), limited spirometry availability in primary care.

🔬 Diagnosis

Clinical Features (All Ages)

  • Episodic wheeze — bilateral, polyphonic, expiratory
  • Recurrent cough — worse at night/early morning
  • Shortness of breath, chest tightness
  • Symptoms triggered by exercise, allergens, URTI, cold air
  • Symptom-free intervals between episodes

Spirometry (>5 years)

  • FEV1/FVC ratio <0.7 = obstructive pattern
  • Reversibility: >12% increase FEV1 post-salbutamol
  • Bronchial challenge (methacholine) if normal spirometry

FeNO (Fractional Exhaled NO)

  • >35 ppb = eosinophilic airway inflammation
  • Guides ICS therapy decisions
  • Useful in atopic children, limited in GCC primary care

⚖️ Differential Diagnosis

Age <1yr Bronchiolitis (RSV)

  • Seasonal (winter), coryza, wheeze, crackles
  • SpO2 drop, feeding difficulty
  • Supportive management — NOT salbutamol
  • Hospitalise if SpO2 <92% or poor feeding

Age <3yr Viral-Induced Wheeze

  • Wheeze only with viral URTI, none between
  • No atopy, no family history
  • Often resolves by school age
  • Treat episodes — not prophylactic ICS initially

Any Age Foreign Body Aspiration

  • Sudden onset, unilateral wheeze, absent breath sounds
  • No fever initially, history of choking event
  • CXR: hyperinflation, mediastinal shift
  • Urgent bronchoscopy — do NOT give bronchodilator

<5yr Croup (Laryngotracheitis)

  • Barking cough, stridor (inspiratory), hoarse voice
  • Worse at night, viral prodrome
  • Nebulised adrenaline + dexamethasone
  • NOT wheeze — upper airway obstruction

Any Age Cardiac Wheeze

  • Heart failure, cardiomyopathy, congenital heart disease
  • Bilateral crackles, hepatomegaly, poor weight gain
  • ECG, echo essential before labelling asthma
  • Diuretics, not bronchodilators

Any Age Other Differentials

  • Vascular ring — stridor, difficulty swallowing
  • Tracheomalacia — expiratory stridor, resolves with age
  • Cystic fibrosis — failure to thrive, recurrent infections
  • Vocal cord dysfunction — inspiratory stridor, anxiety

🧬 Asthma Phenotypes

Allergic Asthma

  • Most common in children — atopic background
  • Positive SPT/RAST (dust mite, pollen, pet dander)
  • Elevated total IgE, eosinophilia
  • Good response to ICS; consider omalizumab if severe

Exercise-Induced

  • Bronchospasm 5–15 min post-exercise
  • Pre-exercise salbutamol 2 puffs 15 min before
  • Warm-up exercises; ICS if frequent
  • Important for school-age children in GCC heat

Non-Allergic Asthma

  • Triggered by infection, cold air, exercise (non-atopic)
  • Normal IgE, negative SPT
  • Often responds less well to ICS alone
  • Consider LTRA (montelukast) adjunct

Aspirin-Exacerbated

  • NSAID/aspirin triggers severe bronchoconstriction
  • Rare in children but important to identify
  • Often with nasal polyps (Samter's triad)
  • Avoid all NSAIDs — paracetamol safe alternative

📊 BTS/GINA Stepwise Management — Under 5 Years

StepTreatmentDetailsNotes
Step 1SABA PRNSalbutamol 100mcg — 2–4 puffs via spacer + mask as neededFor intermittent symptoms only (<3×/week)
Step 2Low-dose ICSFluticasone 50mcg BD via spacer OR Budesonide 200mcg BD nebuliser (under 2)DAILY even when well — education critical
Step 3Add LTRAMontelukast 4mg (age 2–5) / 4mg granules (age 1–2) once daily at nightNOT LABA in under 5s; LTRA is add-on choice
Step 4Specialist ReferralRefer to paediatric respiratory / allergy specialistConsider diagnosis review, adherence, technique
Under 5s — Key: No LABA monotherapy. Spacer with face mask mandatory. Diagnosis must be confident before starting preventer. Review every 3 months.

Step 5BiologicsOmalizumab (anti-IgE, allergic asthma age >6) / Mepolizumab (anti-IL5, eosinophilic age >6)Specialist only; approved by MOH Saudi/DHA UAE

⚠️ ICS Safety: Growth Monitoring

  • Low-dose ICS — minimal/no clinically significant effect on growth
  • High-dose ICS — small reduction in growth velocity (1 cm/year)
  • Benefit of asthma control far outweighs growth risk
  • Plot height/weight every 6 months on centile chart
  • If growth faltering — review dose, technique, alternative ICS
  • Budesonide generally preferred in growth-sensitive cases
Nurse role: Reinforce that low-dose ICS is safe. Parents often stop preventer due to growth/steroid fears — address this at every review.

✅ Preventer Compliance Education

  • ICS must be used daily even when well — not just for attacks
  • Takes 2–4 weeks to reach full anti-inflammatory effect
  • Stopping preventer = increasing exacerbation risk
  • Rinse mouth after ICS — prevents oral candidiasis
  • Use spacer whenever possible — reduces oropharyngeal deposition
  • Adherence monitoring — dose counter, pharmacy refill frequency

Spacer Cleaning (Monthly)

  • Dishwasher OR rinse with warm soapy water
  • Air dry — do NOT towel dry (static build-up)
  • Replace spacer every 6–12 months
  • Metal/anti-static spacers preferred (reduce electrostatic loss)

  • Cyanosis  |  Poor respiratory effort  |  Exhaustion
  • Bradycardia / hypotension  |  Confusion / decreased consciousness
  • Silent chest = air movement so poor wheeze cannot be heard — CRITICAL SIGN

💉 STEP Protocol — Acute Asthma Treatment

S — Salbutamol (Reliever)

  • Mild/Moderate: 4–10 puffs via spacer, repeat q20min × 3
  • Severe/LT: 2.5–5mg nebulised, continuous if needed
  • Spacer as effective as nebuliser for mild/moderate
  • IV salbutamol 15mcg/kg bolus if no IV access, then infusion
  • Monitor: HR, tremor, hypokalaemia with frequent doses

P — Prednisolone (Steroid)

  • Oral: 1–2mg/kg, max 40mg once daily × 3–5 days
  • Give early — full effect at 4–6 hours
  • IV hydrocortisone 4mg/kg q6h if unable to take oral
  • No need to taper if course <7 days

I — Ipratropium (Add in Moderate/Severe)

  • 250–500mcg nebulised q20min × 3 then PRN
  • Combined with salbutamol — synergistic bronchodilation
  • Greatest benefit in first hour of severe asthma
  • NOT for maintenance — only acute use

E — Escalate (Severe/LT Not Responding)

  • IV Magnesium Sulphate: 25–75mg/kg IV (max 2g) over 20 min
  • Indicated: severe/LT not responding after 1 hour
  • Monitor: BP, HR, respiratory rate, knee reflexes during infusion
  • Calcium gluconate at bedside (antidote)
  • Paediatric senior review + consider HDU/ICU transfer
O2 Target: SpO2 94–98% in all children with acute asthma. Use high-flow O2 via face mask if SpO2 <94%. Pulse oximetry continuous monitoring.

📋 Accordions — Acute Protocols

IV Magnesium Sulphate Protocol — Severe Childhood Asthma ▼

Indications

  • Severe or life-threatening acute asthma
  • Not responding to 1 hour of maximal bronchodilator therapy
  • SpO2 persistently <94% despite O2

Dose & Administration

  • Dose: 25–75mg/kg IV, maximum 2g per dose
  • Dilution: Dilute in 100mL 0.9% NaCl or 5% glucose

  • Concentration: Do not exceed 200mg/mL (20%)

Monitoring During Infusion

  • Continuous SpO2 and cardiac monitoring
  • BP every 5 minutes
  • Respiratory rate and depth
  • Knee jerk reflexes (loss = early toxicity sign)
  • Urine output (ensure renal function adequate)

Toxicity Signs & Antidote

  • Loss of deep tendon reflexes — first sign
  • Respiratory depression, cardiac arrest at very high levels
  • Antidote: Calcium gluconate 10% — 0.5mL/kg IV slowly (max 20mL)
  • Keep at bedside throughout infusion
Discharge Criteria & Follow-up Planning ▼

Safe for Discharge When:

  • SpO2 >94% on air for at least 4 hours
  • PEFR >75% predicted (if measurable)
  • Salbutamol requirement <4 hourly
  • Able to eat/drink normally
  • No nocturnal symptoms
  • Parents/carers confident with action plan

Discharge Medications

  • Continue prednisolone to complete 3–5 day course
  • Salbutamol inhaler + spacer (prescribe new spacer if old/damaged)
  • Continue or commence preventer ICS
  • Written asthma action plan in Arabic (GCC standard)

Follow-up

  • GP review within 48 hours of discharge
  • Paediatric asthma nurse clinic within 2 weeks
  • Inhaler technique assessment at follow-up
  • Review potential triggers from admission episode

🧪 Paediatric Acute Asthma Severity Assessment Tool

    💨 MDI + Spacer (Gold Standard <8 years)

    1. Shake the MDI inhaler vigorously for 5 seconds
    2. Remove cap from MDI and spacer mouthpiece/mask
    3. Insert MDI into back of spacer
    4. Seal mask over nose and mouth — no gaps (infant/toddler); mouthpiece in mouth if >4 years
    5. Actuate ONE puff into spacer
    6. Breathe — 5–10 tidal breaths OR hold breath 10 seconds (older child)
    7. NEVER actuate multiple puffs before breathing — drug waste
    8. Wait 30–60 seconds before next puff if multiple doses needed
    9. After ICS: rinse mouth with water and spit
    Mask seal check: Pharmacist/nurse should observe technique at every appointment. A 1cm gap in mask seal reduces drug delivery by 40–50%.

    🌀 DPI Devices (>5–6 years)

    Turbohaler (Budesonide/Formoterol)

    • Hold upright, twist base and click to load dose
    • Exhale away from device — do NOT breathe out into it
    • Seal lips around mouthpiece, inhale FAST and DEEP
    • Hold breath 10 seconds
    • Requires peak inspiratory flow >30–60 L/min
    • Dose counter — counsel when near empty (no dose sensation)

    Accuhaler (Seretide/Fluticasone)

    • Open device, slide lever to load dose
    • Exhale away, seal lips, inhale STEADILY (less forceful than Turbohaler)
    • Hold breath 10 seconds, close device after use
    • Dose counter visible — 60 dose device

    Nebuliser vs Spacer

    • Spacer + MDI equally effective as nebuliser for acute asthma
    • Spacer preferred: faster, no electricity, less distressing
    • Nebuliser: when very distressed, <2 years (better seal), unable to coordinate
    • Nebuliser aerosol risk in closed spaces — COVID/MERS consideration

    🧼 Spacer Cleaning — Step by Step

    Click to expand: Full Spacer Cleaning Protocol ▼

    Method A — Dishwasher

    1. Disassemble all parts (remove mask/mouthpiece if detachable)
    2. Place in dishwasher — top rack
    3. Normal wash cycle (no need for high heat)
    4. Air dry ONLY — do not towel dry
    5. Allow to dry fully before use (standing upright)
    6. Reassemble when completely dry

    Method B — Hand Wash

    1. Disassemble spacer
    2. Rinse in warm water with household dish soap
    3. Swirl — do NOT scrub (creates static)
    4. Rinse thoroughly to remove all soap
    5. Air dry upright — never towel dry
    6. Reassemble when fully dry

    Electrostatic & Anti-static Tips

    • Electrostatic charge on plastic spacers attracts drug particles — reduces drug delivery by up to 40%
    • Washing with soapy water reduces static significantly
    • Metal spacers (Volumatic, Able Spacer) have no electrostatic effect
    • Anti-static plastic spacers (AeroChamber Plus) preferred for children
    • Priming (firing 5 puffs into new spacer) reduces static initially

    DO NOT:

    • Towel dry — creates static charge
    • Use cloth or paper to dry inside
    • Clean more than monthly (removes anti-static coating some devices)
    • Use bleach or strong disinfectants

    Replacement Schedule

    • Replace spacer every 6–12 months
    • Replace mask when child grows (ensure good seal)
    • Replace if cracked, discoloured, or valve stuck

    Note: Provide this plan in Arabic for GCC families — خطة العمل للربو (Asthma Action Plan)

    🏠 Trigger Identification & Avoidance

    House Dust Mite (HDM)

    • Impermeable mattress and pillow covers
    • Wash bedding >60°C weekly
    • Remove carpets in bedroom if possible
    • Reduce indoor humidity <50%

    Smoke Exposure

    • Complete smoking ban in home and car
    • Shisha smoke — equally harmful, passive exposure
    • Outdoor smoking still deposits particles on clothing
    • Refer parents for smoking cessation

    Exercise

    • Pre-exercise salbutamol 2 puffs, 15 min before
    • 5–10 min warm-up reduces bronchoconstriction
    • Swimming preferred — warm, humid air
    • School PE teacher must be informed — action plan copy

    Viral URTI

    • Most common trigger in school-age children
    • Consider doubling preventer ICS at first sign of cold
    • Start action plan early — do not wait for severe symptoms
    • Annual influenza vaccination recommended

    🏫 School & Nursery Management

    • Provide written asthma action plan to school/nursery
    • Spare reliever inhaler kept at school (with spacer)
    • Designated trained staff member — inhaler administration
    • Child must be able to access reliever immediately
    • Identify PE teacher — exercise-induced management plan
    • Field trips — ensure inhaler and plan accompany child
    Saudi MOE: Schools required to hold approved asthma plans. HAAD (Abu Dhabi) and DHA (Dubai) provide templates in Arabic/English.

    GINA Patient Education

    • GINA patient guide available in Arabic — free download
    • Asthma Foundation GCC patient resources
    • Saudi Chest Disease Association patient leaflets
    • Digital apps (AsthmaMD, Asthma Buddy) — language settings

    Pet Dander

    • Removal of pet is most effective intervention
    • If not possible: keep pet out of bedroom, wash pet weekly
    • HEPA filters may reduce airborne allergen load
    • Counselling: sensitisation can persist years after removal

    🌍 GCC-Specific Asthma Triggers & Context

    Dust Storms (Haboob)

    • Fine particulate matter (PM2.5) triggers acute exacerbations
    • Issue sandstorm advisory — reduce/avoid outdoor activity
    • Wear N95 mask if outdoor exposure unavoidable
    • Pre-emptive salbutamol before outdoor exposure
    • Close windows, use air purifiers during events
    • Monitor air quality apps (Hawa'ak — Saudi; AirQ UAE)

    Coastal Humidity (UAE/Qatar)

    • High relative humidity promotes dust mite & mould growth
    • Air conditioning creates cold-dry indoor air — paradoxical trigger
    • AC filters must be cleaned regularly (mould spores)
    • Dehumidifiers in bedrooms — target <50% RH

    Shisha/Hookah Exposure

    • Increasingly common in GCC — social family settings
    • Passive shisha smoke equivalent to or worse than cigarettes
    • Children present at family shisha sessions — significant exposure
    • Strong counselling: no shisha at home or near children

    MERS-CoV Exacerbations

    • MERS-CoV endemic in Arabian Peninsula — camel exposure risk
    • Respiratory virus — significant asthma exacerbation trigger
    • Avoid direct camel contact in children with asthma
    • Unpasteurised camel milk — additional exposure risk
    • Hospital isolation protocols during MERS season

    Ramadan — Inhaler Use

    • Inhaled medication does NOT break the fast
    • Fatwa consensus — inhaler aerosol not considered food/drink
    • Critical reassurance — many families stop preventer during Ramadan
    • Oral prednisolone/tablets DO break the fast — consult scholar
    • Consider nebuliser timing around Iftar/Suhoor if concerned
    • Dehydration during fasting — increased mucus viscosity risk

    Traditional Remedies

    • Black seed (Nigella sativa / Habbatus Sauda) — some adult trial evidence for bronchodilation
    • NOT a substitute for prescribed preventer or reliever therapy
    • Honey — soothing but not evidence-based for asthma control
    • Camel urine — culturally used; no evidence, infection risk
    • Acknowledge cultural practices respectfully — integrate into education

    📚 GCC Nursing MCQs — Childhood Asthma

    1. A 4-year-old child in Riyadh presents with wheeze during a dust storm. SpO2 is 91%, she is using accessory muscles and can only speak in words. What is the BTS severity classification?

    A. Mild asthma B. Moderate asthma C. Severe asthma D. Life-threatening asthma
    SpO2 <92%, words only, significant accessory muscle use all meet life-threatening criteria. The silent chest is the most ominous sign — however SpO2 <92% alone qualifies for life-threatening classification per BTS guidelines. Immediate emergency team activation required.

    2. A Muslim parent asks whether their 8-year-old child should use their fluticasone preventer inhaler during Ramadan. What is the correct advice?

    A. Stop the inhaler during Ramadan as it breaks the fast B. Continue the inhaler — inhaled medication does not break the fast C. Switch to oral montelukast instead during Ramadan D. Use only at Iftar and Suhoor times
    Islamic scholarly consensus (fatwa) confirms that inhaled aerosol medications do not break the Ramadan fast as they do not constitute food or drink. Reassuring families on this point is critical — stopping preventer ICS during Ramadan leads to poorly controlled asthma and increased exacerbation risk. The ICS must be taken daily as prescribed.

    3. A 6-year-old child receives IV magnesium sulphate 50mg/kg over 20 minutes for life-threatening asthma. During the infusion, the nurse notes absent knee jerk reflexes. What is the priority action?

    A. Continue the infusion — this is an expected finding B. Increase the infusion rate to complete it faster C. Stop the infusion immediately and administer calcium gluconate D. Check serum magnesium level and await result before acting
    Loss of deep tendon reflexes (knee jerk) is the earliest sign of magnesium toxicity and precedes respiratory depression and cardiac arrest. The infusion must be stopped immediately. The antidote is calcium gluconate 10% — 0.5mL/kg IV slowly (maximum 20mL) — which should be kept at the bedside throughout the magnesium infusion.

    4. A mother uses a plastic MDI spacer for her 3-year-old's salbutamol. She cleans it daily by drying it thoroughly with a towel. The child's asthma remains poorly controlled despite good technique. What is the most likely problem with spacer management?

    A. She is cleaning it too frequently B. Towel drying creates electrostatic charge which reduces drug delivery C. She should use a nebuliser instead for this age group D. Daily cleaning removes the anti-drug coating
    Towel drying a plastic spacer generates significant electrostatic charge on the internal surface. This charge attracts drug particles, dramatically reducing the amount of medication reaching the airways (by up to 40–50%). Spacers should be air-dried only. Monthly cleaning with warm soapy water followed by air drying is recommended. Consider switching to a metal spacer (e.g., Volumatic) which is electrostatic-free.

    5. A family from Jeddah mentions they give their child with asthma black seed (Nigella sativa) oil daily as advised by a traditional healer, in place of the prescribed fluticasone. What is the most appropriate nursing response?

    A. Agree that black seed has proven asthma benefits and can replace ICS B. Dismiss the practice entirely and insist they stop immediately C. Acknowledge the cultural practice respectfully, explain ICS must not be stopped, and clarify black seed has limited paediatric evidence D. Report the family to child protection services for non-adherence
    Cultural humility is essential in GCC nursing practice. Nigella sativa has some small adult trial evidence suggesting mild bronchodilatory effects, but there is insufficient paediatric evidence to support its use as an asthma controller. The correct approach is: (1) Respectfully acknowledge the family's cultural practice; (2) Clearly explain that ICS preventer therapy is essential and must not be replaced; (3) Educate on the mechanism and importance of ICS; (4) If the family wishes to continue black seed as a complement (not replacement), this can be discussed with the paediatric respiratory team.
