Paediatrics: Acute Asthma in Children: Free MSRA Podcast

⚕️ FREE MSRA PODCAST – Acute Asthma in Children🎧 A clear, high-yield breakdown of this paediatric respiratory emergency – perfect for exam prep and real-life clinical scenarios.🧠 Key Learning Points📌 Definition• Acute asthma in children is a sudden worsening of asthma symptoms (wheeze, breathlessness, chest tightness, cough) due to airway inflammation and narrowing.📌 Causes & Risk Factors• Viral respiratory infections (most common)• Allergens (pollen, dust mites, pet dander)• Cold air, exercise• Air pollution, cigarette smoke• Emotional stress• Family history of asthma/allergy, previous attacks• Mnemonic: “VACCINE” – Viral, Allergens, Cold air, Cigarette smoke, Irritants, Noted history, Exercise📌 Pathophysiology• Airway inflammation, bronchial hyperreactivity, and increased mucus• Bronchoconstriction narrows the airways, reduces airflow• Chronic sensitivity + acute trigger = sudden symptoms📌 Symptoms• Expiratory wheeze, breathlessness, tachypnoea• Cough (often nocturnal), chest tightness• Use of accessory muscles, nasal flaring, retractions• Difficulty speaking/feeding (sign of severity)• Mnemonic: “WHEEZE” – Wheeze, Hard breathing, Exhaustion, Exercise-triggered, Zero air, Eating/feeding difficulties📌 Differential Diagnosis• Bronchiolitis• Pneumonia• Foreign body aspiration• Cystic fibrosis• Vocal cord dysfunction• ITP, allergy, GORD (rarely in exam)📌 Diagnosis• Clinical assessment (history & exam)• Oxygen saturation (SpO2)• Peak expiratory flow rate (PEFR, if age >5)• Consider chest X-ray only if complications/doubt• ABGs if life-threatening• Tip: “If you hear a wheeze, always check SpO2!”📌 Management• Immediate: Inhaled salbutamol (via spacer/nebuliser)• Oxygen if SpO2 <94% (aim for 94–98%)• Oral/IV corticosteroids (prednisolone or hydrocortisone)• Add nebulised ipratropium for severe attacks• IV magnesium sulphate/aminophylline if poor response• Admit if severe/life-threatening or poor response• Long-term: Inhaled corticosteroids, asthma action plan, trigger avoidance, GP/specialist follow-up• NICE/UK priorities: Follow paediatric asthma pathways, rapid escalation if life-threatening📌 Complications• Respiratory failure, hypoxia• Pneumothorax, atelectasis• Hospital/ICU admission• Poor growth, missed school, psychological impact📌 Prognosis• Excellent with prompt treatment and ongoing control• Many children improve with age, but some have persistent symptoms into adulthood📎 More MSRA Resources for Acute Asthma in Children📝 Revision Notes: https://www.passthemsra.com/topic/acute-asthma-in-children-revision-notes/🧠 Flashcards: https://www.passthemsra.com/topic/acute-asthma-in-children-flashcards/💬 Accordion Q&A Notes: https://www.passthemsra.com/topic/acute-asthma-in-children-accordion-qa-notes/🚀 Rapid Quiz: https://www.passthemsra.com/topic/acute-asthma-in-children-rapid-quiz/🎓 Full Course: https://www.passthemsra.com/courses/paediatrics-for-the-msra/#MSRA #MSRARevision #MSRATextbook #MSRAQuiz #MSRAQuestionBank #MSRAFlashcards #MSRAQ&ANotes #MSRAAccordions #MultiSpecialityRecruitmentAssessment #MSRAOnlineRevision #MSRARevisionWebsite #AcuteAsthmaInChildren
