Paediatrics: Congenital Diaphragmatic Hernia: Free MSRA Podcast

⚕️ FREE MSRA PODCAST – Congenital Diaphragmatic Hernia (CDH)🎧 A clear, high-yield breakdown of this serious neonatal respiratory condition – perfect for exam prep and real-life clinical scenarios.🧠 Key Learning Points📌 Definition• A birth defect where a hole in the diaphragm allows abdominal organs to herniate into the chest, impairing lung development and function.📌 Causes & Risk Factors• Usually idiopathic, but may involve:Genetic mutations (e.g. 15q24–q26)Chromosomal abnormalities (Trisomies 13, 18, 21)Maternal factors: smoking, diabetes, SSRIs, advanced age🧠 Mnemonic: "CDH = Congenital Defect Herniation"📌 Pathophysiology• Failure of diaphragm to close → intestines/stomach/herniate into thorax• Leads to:Pulmonary hypoplasiaPulmonary hypertensionSurfactant dysfunction• Common defect: Bochdalek hernia (posterolateral, usually left-sided)📌 Symptoms• Severe respiratory distress at birth• Cyanosis, tachypnoea, scaphoid abdomen• Bowel sounds in chest, decreased breath sounds🧠 Mnemonic: “BABY GASPS”B – Bowel sounds in chestA – Absent breath soundsB – Blue skin (cyanosis)Y – Yawning (struggling to breathe)G – Gas (no bag-mask!)A – Abdomen sunkenS – Surfactant problemP – Pulmonary hypoplasiaS – Sternal shift (mediastinal displacement)📌 Differential Diagnosis• Pneumothorax• Meconium aspiration• Pleural effusion• Persistent pulmonary hypertension of the newborn (PPHN)📌 Diagnosis• Prenatal ultrasound• Chest X-ray postnatally shows bowel in thorax• Blood gases (watch for hypoxaemia)• Echo, renal & cranial US for associated anomalies🧠 Tip: Avoid bag-mask ventilation📌 Management• Immediate:Intubation + ventilation (avoid bag-mask)Insert NG tube to decompress stomachSurfactant + IV fluids• Ongoing:Gentle ventilation (avoid barotrauma)Nitric oxide or ECMO if severe• Delayed surgery once stable – return organs, patch diaphragm• Consider fetal tracheal occlusion in specialist centres pre-birth📌 Complications• Chronic lung disease• Pulmonary hypertension• GERD• Hearing loss• Developmental delays• Failure to thrive📌 Prognosis• Varies by severity and centre• Survival ~50% overall, up to 80% with early diagnosis + specialist care• Long-term care often needed for respiratory, GI, and developmental issues📎 More MSRA Resources for Congenital Diaphragmatic Hernia📝 Revision Notes:https://www.passthemsra.com/topic/congenital-diaphragmatic-hernia-revision-notes/🧠 Flashcards:https://www.passthemsra.com/topic/congenital-diaphragmatic-hernia-flashcards/💬 Accordion Q&A Notes:https://www.passthemsra.com/topic/congenital-diaphragmatic-hernia-accordion-qa-notes/🚀 Rapid Quiz:https://www.passthemsra.com/topic/congenital-diaphragmatic-hernia-rapid-quiz/🎓 Full Course:https://www.passthemsra.com/courses/paediatrics-for-the-msra/#MSRA #MSRARevision #MSRATextbook #MSRAQuiz #MSRAQuestionBank #MSRAFlashcards #MSRAQandANotes #MSRAAccordions #MultiSpecialityRecruitmentAssessment #MSRAOnlineRevision #MSRARevisionWebsite #CongenitalDiaphragmaticHernia
