30.3 🩺 內科專科考前版

30.3.0.1 📌 䞀頁重點

  • 22E 匷調FOUR Score 替代 GCS、targeted temperature management、prognostication
  • Disorders of Consciousness spectrum
  • Brain death criteria 國際 update
  • Taiwan噚官移怍法 + 腊死刀定

30.3.0.2 🧠 進階機蜉

30.3.0.2.1 ARAS Network
  • Brainstem reticular formation → thalamus → cortex
  • 任䞀階段倱敗 → coma
  • ICP ↑ → herniation → progressive ARAS damage
30.3.0.2.2 Anoxic Brain Injury
  • 心跳停止 > 4-5 min → 䞍可逆
  • Hippocampus, cortex layer 3-5, basal ganglia 最敏感

30.3.0.3 💊 進階管理

30.3.0.3.1 FOUR Score (Full Outline of UnResponsiveness)
  • 4 components × 4 points each = 0-16
  • Eye, Motor, Brainstem reflexes, Respiration
  • 比 GCS 對 intubated 病人曎適甚
  • Predict mortality + outcome
30.3.0.3.2 Targeted Temperature Management (TTM) post-cardiac arrest
  • 32-36°C × 24h
  • Improve neurological outcome
  • Now: TTM2 trial 顯瀺 36°C ≈ 33°C
  • Avoid fever ≥ 37.7°C × 72h
30.3.0.3.3 Prognostication After Cardiac Arrest
  • Multimodal at 72h post-ROSC:
    • Neurological exam (myoclonus, no reflexes)
    • SSEP (somatosensory evoked potential N20 absent)
    • EEG (burst-suppression, status myoclonus)
    • NSE (neuron-specific enolase) > 60 ng/mL at 48-72h
    • MRI
30.3.0.3.4 Brain Death Criteria國際
  • Etiology + irreversibility
  • Coma
  • Absent brainstem reflexes
  • Apnea test
  • 確認 (interval, second exam, ancillary test for child)
  • Ancillary tests: EEG, cerebral angiography, transcranial Doppler, nuclear scan

30.3.0.4 🌟 Pearls (10)

  1. 「Coma cocktail」 still standard
  2. Locked-in syndrome 是悲劇性 misdiagnosis
  3. Anoxic brain injury 4 min 䞍可逆
  4. TTM 32-36°C × 24h post-arrest
  5. Multimodal prognostication > single test
  6. Cushing’s reflex 是 late sign of ↑ICP
  7. Hyperventilation 短期 emergent ↑ICPPaCO2 30-35
  8. Mannitol / hypertonic saline for ↑ICP
  9. Brain death is clinical diagnosis (multiple confirmations)
  10. Family communication 是 ICU 重芁環節

30.3.0.5 🔍 特殊情境

  • Mannitol 0.5-1 g/kg / hypertonic saline
  • CSF drainage (EVD)
  • Decompressive craniectomy
  • Sedation + paralysis
30.3.0.5.2 2. Status Epilepticus 埌 coma
  • AED + EEG monitor
  • Treat refractory (ICU)
30.3.0.5.3 3. Hepatic encephalopathy
  • Lactulose
  • Rifaximin
  • Treat trigger
30.3.0.5.4 4. Hypothermia

  • Don’t pronounce death until rewarmed

30.3.0.6 📍 台灣 Context

  • 健保 ICU + monitoring
  • 腊死刀定 → 噚官移怍法
  • 兒科腊死暙準范嚎
  • 家屬溝通 + 醫倫委員會

30.3.0.7 ⚠ 老闆地雷

  1. 䞍查 glucose
  2. Glucose before thiamine
  3. Locked-in 當 coma
  4. GCS ≀ 8 䞍 intubate
  5. ↑ICP 䞍評䌰
  6. 早早 prognosticate< 72h post-arrest
  7. Brain death criteria 䞍嚎
