Paediatrics: Acute Epiglottitis: Free MSRA Podcast

⚕️ FREE MSRA PODCAST – Acute Epiglottitis🎧 A clear, high-yield breakdown of this life-threatening paediatric airway emergency – perfect for exam prep and real-life clinical scenarios.🧠 Key Learning Points📌 Definition• Acute epiglottitis is a severe bacterial infection causing rapid inflammation and swelling of the epiglottis – the flap that guards the airway. It can lead to sudden airway obstruction and respiratory failure.📌 Causes & Risk Factors• Haemophilus influenzae type B (HiB) – primary historical cause• Other bacteria (e.g., Streptococcus, Staphylococcus)• Viral infections and trauma (less common)• Risk factors:• Unvaccinated or incompletely vaccinated children• Immunosuppressed individuals• Exposure to tobacco smoke💡 Mnemonic: “HIB = Huge Inflammatory Blockage”📌 Pathophysiology• Bacterial invasion of epiglottic tissue triggers rapid inflammatory response• Leads to significant swelling, narrowing the upper airway• Even mild oedema can completely block airflow due to small airway diameter in children• Results in sudden onset respiratory distress and hypoxia📌 Symptoms• High fever, severe sore throat• Drooling (due to painful or impaired swallowing)• Muffled “hot potato” voice• Stridor – high-pitched inspiratory sound• Tripod position – child leaning forward to optimise breathing• Rapid deterioration within hours💡 Mnemonic: “Air BLOCKED” – Airway risk, Breathing difficulty, Lethargy, Oedema, Cough absent, K position (Tripod), Drooling📌 Differential Diagnosis• Croup• Peritonsillar abscess• Retropharyngeal abscess• Pharyngitis or laryngitis• Inhaled foreign body• Severe laryngotracheobronchitis📌 Diagnosis• Clinical suspicion is key – do not use tongue depressor if airway is compromised• Laryngoscopy under anaesthetic in OR – gold standard• Lateral neck X-ray – shows thumbprint sign• Throat swabs and blood cultures – only after airway is secure• CT/MRI – if abscess suspected📌 Management• Immediate hospitalisation – emergency situation• Airway first – possible intubation or tracheostomy in severe cases• IV antibiotics – broad-spectrum covering H. influenzae and others• IV corticosteroids – to reduce airway oedema• ICU/HDU monitoring• Prophylactic rifampicin for household contacts if HiB confirmed✅ NICE-aligned: Prioritise airway protection, then treat underlying infection📌 Complications• Complete airway obstruction• Respiratory arrest• Pneumonia• Sepsis• Epiglottic abscess• Rare: Meningitis, pneumothorax, pneumomediastinum📌 Prognosis• Excellent with prompt diagnosis and treatment• Mortality is low if airway is secured early• 15% may require intubation• Delay = high risk of fatal outcome📎 More MSRA Resources for Acute Epiglottitis📝 Revision Notes: https://www.passthemsra.com/topic/acute-epiglottitis-revision-notes/🧠 Flashcards: https://www.passthemsra.com/topic/acute-epiglottitis-flashcards/💬 Accordion Q&A Notes: https://www.passthemsra.com/topic/acute-epiglottitis-accordion-qa-notes/🚀 Rapid Quiz: https://www.passthemsra.com/topic/acute-epiglottitis-rapid-quiz/🎓 Full Course: https://www.passthemsra.com/courses/paediatrics-for-the-msra/Hashtags#MSRA #MSRARevision #MSRATextbook #MSRAQuiz #MSRAQuestionBank #MSRAFlashcards #MSRAQ&ANotes #MSRAAccordions #MultiSpecialityRecruitmentAssessment #MSRAOnlineRevision #MSRARevisionWebsite #Paediatrics #AcuteEpiglottitis
