Resp: Tension Pneumothorax: Free MSRA Podcast

🫁FREE MSRA PODCAST –Tension PneumothoraxFast, focusedrevision on a true surgical emergency youmust recognise and treat without delay. Life-saving knowledge for the MSRA andclinical practice. 🧠Key Learning Points📌Definition• Tension pneumothorax = trapped air under pressure in the pleural space• Acts like a one-way valve → air enters but cannot escape• Leads to lung collapse, mediastinalshift, and cardiovascular collapse 📌Causes• Trauma: rib fracture, stab wound, car crash• Iatrogenic: central line insertion, mechanicalventilation• Lung disease: COPD, previous pneumothorax• Spontaneous: can develop from a simplepneumothorax 📌Symptoms• Sudden-onset pleuritic chest pain• Severe dyspnoea, tachypnoea, tachycardia• Tracheal deviation (late sign)• Absent breath sounds and hyper-resonance on affected side• Raised JVP, hypotension,cyanosis, shock,cardiac arrest 🩺Mnemonic: PRESSUREP – Pleuritic painR – Respiratory distressE – Emphysema / hyper-resonanceS – Shift (tracheal deviation)S – Sound (decreased breath sounds)U – Unequal chest expansionR – Raised JVPE – Extremely low BP (cardiovascular collapse) 📌Diagnosis• Clinical diagnosis – Do NOT delay forinvestigations• CXR may show lungcollapse and mediastinal shift afterstabilisation• CT chest forstable cases or unclear causes only 📌Emergency Management🚨Do not wait forimaging if suspected clinically• Immediate needle decompression:→ 2nd intercostal space mid-clavicular line (or4th–5th intercostal mid-axillary line)→ Use large bore cannula – listen for hissing soundas trapped air escapes• Followed by chest drain insertion in safe triangle• Oxygen, analgesia, monitor vitals• Consider antibiotics in trauma cases• Surgery if airleak persists beyond a few days 📌Complications• Respiratory failure• Cardiac arrest• Hypoxic brain injury• Re-expansion injury• Death if treatment delayed 📌Prognosis• Excellent with prompt treatment• Catastrophic if diagnosis is delayed 📎More TensionPneumothorax MSRA Resources:📝 Revision Notes: https://www.passthemsra.com/topic/tension-pneumothorax-revision-notes/🧠 Flashcards: https://www.passthemsra.com/topic/tension-pneumothorax-flashcards/💬 Accordion Q&A Notes: https://www.passthemsra.com/topic/tension-pneumothorax-accordion-qa-notes/🚀 Rapid Quiz: https://www.passthemsra.com/topic/tension-pneumothorax-rapid-quiz/🎓 Full Course: https://www.passthemsra.com/courses/respiratory-for-the-msra/ Hashtags#MSRA#TensionPneumothorax #MSRARevision #RespiratoryMSRA #NeedleDecompression#SurgicalEmergency #MSRAFlashcards #MedicalEducation #MSRAOnlineRevision#PassTheMSRA
