Asthma Flashcards

(46 cards)

1
Q

What features of symptoms increase the likelihood of asthma?

A
  • Symptoms vary over time and intensity
  • Worse at night or early morning
  • Triggered by exercise, allergens, cold air, or viral infections
  • Improve with bronchodilators

These features help differentiate asthma from other respiratory conditions.

Q

What factors increase the likelihood that recurrent wheeze represents asthma rather than viral bronchiolitis? (4)

A
  • Personal history of eczema
  • Parental history of asthma
  • Wheeze occurring without viral infections
  • Allergic sensitization

These factors help differentiate asthma from other respiratory conditions.

Q

What is the preferred reliever medication for asthma symptoms in pediatrics?

A

Short-acting beta agonist (SABA) – salbutamol

SABA is commonly used for quick relief of asthma symptoms.

20
Q

What is the preferred controller medication for persistent asthma in pediatrics?

A

Low-dose inhaled corticosteroid (ICS)

ICS helps manage chronic asthma symptoms.

21
Q

When should daily ICS therapy be started in children ≤5 years? (3)

A
  • Symptoms ≥3 times per week
  • Night awakenings due to asthma
  • Frequent wheezing episodes requiring SABA

These criteria indicate the need for regular treatment.

22
Q

What is the preferred inhaler delivery method for young children?

A

MDI with spacer

This method ensures effective medication delivery.

23
Q

What additional device is required for children under ~5 years when using a spacer?

A

Face mask

A face mask helps ensure proper inhalation of medication.

24
Q

What medication can be considered as an alternative controller if ICS cannot be used?

A

Leukotriene receptor antagonist (montelukast)

This medication can help control asthma symptoms when ICS is not suitable.

25
What are common **side effects** of inhaled corticosteroids in children? (3)
* Oral candidiasis * Dysphonia * Mild growth velocity reduction (small, usually temporary) ## Footnote Monitoring for side effects is important during treatment.
26
What is the most common **trigger** of asthma exacerbations?
Viral respiratory infections ## Footnote These infections frequently lead to worsening asthma symptoms.
27
What are signs of a **severe asthma exacerbation** in children? (5)
* Unable to speak or feed normally * Marked tachypnea * Chest retractions or accessory muscle use * Oxygen saturation <92% * Drowsiness or agitation ## Footnote Recognizing these signs is critical for timely intervention.
28
What **monitoring** should be done in children receiving long-term ICS therapy? (3)
* Growth monitoring (height) * Asthma symptom control * Inhaler technique ## Footnote Regular monitoring helps ensure effective treatment and safety.
29
When should **referral to a specialist** be considered? (4)
* Poor asthma control despite moderate-dose ICS * Frequent severe exacerbations * Uncertain diagnosis * Life-threatening asthma episode ## Footnote These situations warrant specialist evaluation for better management.
30
What key **education** should be given to parents of children with asthma? (4)
* Correct inhaler technique * Recognition of exacerbation symptoms * Proper reliever use * Written asthma action plan ## Footnote Educating parents is crucial for effective asthma management.
31
How can you diagnose asthma in a child 1- 5 y/o?
≥ 2 episodes of: 1 - Documented airflow obstruction (wheeze, cough, difficulty breathing) Preferably documented by the physician 2 - Documented reversibility of airflow obstruction Preferred: physician observes improvement w/ SABA +/- oral steroids Alternative: Convincing parent report of improved symptoms after a 3 mo trial of medium-dose of ICS
32
How much should the FEV1 drop in a positive methacoline challenge test?
FEV1 < 20%
33
Asthma is considered well-controlled in children if: (6)
Daytime sx: ≤ **2d/**w Night sx: ≤ **1x/**w Physical activity: Normal Exacerbation: mild, infrequent Absence from work/school: none FEV1 or PEF: ≥** 90%** of personal best PEF diurnal variation:** < 10 - 15%**
34
Four non-pharmacological management strategies in asthma
Avoid triggers as much as possible (including NSAIDs) Encourage aerobic exercise Smoking cessation Annual influenza vaccination
35
Step 1 of asthma treatment in childrne 6 - 11 y/o
Low-dose ICS taken **whenever SABA is taken**
36
Step 2 of asthma treatment in childrne 6 - 11 y/o
Daily low-dose ICS only
37
Step 3 of asthma treatment in childrne 6 - 11 y/o
* Low-dose ICS-LABA OR * Medium dose ICS
38
Step 4 of asthma treatment in childrne 6 - 11 y/o
* Medium dose ICS-LABA
39
What is the severity score for asthma exacerbation in children < 6 mo?
PRAM score (Pediatric Respiratory Assessment Measure)
40
What are the components of the PRAM score?
**“S.O.A.T.S.”** S – Suprasternal retractions O – Oxygen saturation A – Air entry T – Tachypnea (respiratory rate) S – Scalene muscle contraction
41
What is considered a severe asthma exacerbation in children?
PRAM score > 8 ( - Audible wheezing/silent chest - Absent air entry - SpO2 < 92%)
42
What is the management for asthma exacerbations in children < 6 y/o based on the PRAM severity score?
**Mild**: Salbutamol + oral steroids **Moderate**: Oral steroids + salbutamol + ipratropium Consider admission **Severe**: Oral steroids + salbutamol + ipratropium Other supportive measures: IV, NPO, nebulized salbutamol, IV magnesium sulfate
43
After ED discharge for asthma, name TWO key follow-up components.
- Provide an asthma action plan - review inhaler technique (other acceptable: address adherence barriers, review goals of care, daily PEF monitoring)
44
What are the three zones of a standard asthma action plan? (3)
Green — Well controlled; continue controller meds Yellow — Worsening symptoms; increase reliever / step-up therapy Red — Severe symptoms; rescue meds and seek urgent care
45
What key elements should be included in an asthma action plan? (5)
Daily controller medications with doses Reliever medication instructions Symptom or peak-flow thresholds for zones Steps for worsening symptoms When to seek urgent/emergency care
46
According to GINA 2025, what is the preferred reliever medication for asthma in children ≤5 years and why? (2)
Short-acting β₂-agonist (SABA) (e.g., **salbutamol**) **Reason: **insufficient evidence supporting ICS–formoterol reliever therapy in preschool children
