  5. BRAIN CT (C-)

  6. MORE HISTORY?MORE PE?FIRST IMPRESSION?INITIAL ORDER? 你還想問什麼? 你心中有哪些differentialdiagnosis? 想讓病人做什麼檢查?

  7. More History • Allergy • Medication • Past history • Last period/ Last meal • Event/ environment

  8. More PE • Neurologic examination • Cranial nerve, facial palsy, muscle power • Meningismus • barbinski sign • gait • Special odor • Needle puncture • Skin rash, skin turgor

  9. Hypertensive emergency • Hypertensive urgencyis a clinical presentation associated with severe elevations in blood pressure without progressive target organ dysfunction. • Hypertensive emergencyis an acute elevation of blood pressure (180/120 mm Hg) associated with end-organ damage, specifically, acute effects on the brain, heart, aorta, kidneys, and/or eyes • The majority of patients who present with a hypertensive emergency have a history of hypertension (84% to 93%) Tintinalli’s emergency medicine, 7ed, Ch 61

  10. Tintinalli’s emergency medicine, 7ed, Ch 61

  11. Acute neurologic symptoms and severe hypertension • Intracranial hemorrhage • Subarachnoid bleeding • Acute stroke • Hypertensive encephalopathy • Hypertensive encephalopathy is characterized by insidious onset of headache, nausea and vomiting, followed by non-localizing neurologic symptoms such as restlessness, confusion, seizure or coma. • UptoDate 2012 Tintinalli’s emergency medicine, 7ed, Ch 61

  12. Hypertensive encephalopathy • Hypertensive encephalopathy is (1) acute in onset and (2) reversible. • Hypertensive encephalopathy is an uncommon syndrome resulting from an abrupt, sustained rise of BP that exceeds the limits of cerebral autoregulation of the small resistance arteries in the brain. (MAP >160 mmHg) Tintinalli’s emergency medicine, 7ed, Ch 61 Rosen’s emergency medicine, Ch83 hypertension

  13. 2013/09/23 08:27(00:12) • Impression: • Malignant neoplasm of brain stem • Hypertension • General weakness • Shortness of breath

  14. 2013/09/23 08:27(00:12) • CBC/DC, PT, APTT • BUN, CR, NA, K, CA, BILIRUBIN(T), AST, ALT, SUGAR, ALBUMIN,AMMONIA, TROPONIN I, ABG • U/A, ICON • EKG, CXR • 備血:一般用血 血品 :PRB 2U,FFP 2U,PC 12U • RECHECK BP 30 mins later   • O2 2L/min   • Hydralazine 20mg 0.5amp IV stat  

  15. Medication choice?Target BP? 如果是你,你會用什麼藥物降血壓? 你想要把血壓控制在多少?

  16. Blood pressure reduction • Blood pressure reduction in the setting of neurologic emergencies typically requires emergency CT scanning to determine diagnosis, treatment thresholds, and priorities. • Hypertensive encephalopathy is the clearest indication for blood pressure reduction • Blood pressure reduction is controversial in the setting of acute vascular lesions, subarachnoid hemorrhage, intracranial hemorrhage, and ischemic stroke. Tintinalli’s emergency medicine, 7ed, Ch 61

  17. Hypertensive encephalopathy • Hypertensive encephalopathy is a true medical emergency, rapid measured reduction of BP is mandatory • Excessive reduction of BP must be avoided to prevent increasing cerebral ischemia. • The standard treatment regimen is intravenous (IV) nitroprusside with a careful reduction of the MAP by 25% or to a minimum diastolic pressure of 110 mm Hg over an hour. Rosen’s emergency medicine, Ch83 hypertension

  18. Tintinalli’s emergency medicine, 7ed, Ch 61

  19. Goal of hypertension control • Hypertensive encephalopathy • Decrease MAP 15%–20% • Subarachnoid hemorrhage • SBP< 160mmHg or MAP < 130mmHg • Intracranial hemorrhage • P’t with suspicion of elevated ICP: MAP <130mmHg • P’t without suspicion of elevated ICP: MAP < 110mmHg or SBP < 160mmHg • Acute ischemic stroke • If fibrinolytic therapy planned, treat if >185/110 mm Hg. • Treat if >220/120 mm Hg on third of three measurements, spaced 15 min apart

  24. NEXT STEP? 你覺得這個病人是怎麼了? 接下來你想要做什麼?

  25. Sympathetic crisis • Pheochromocytoma • Headache, alternating periods of normal and elevated blood pressure, tachycardia, and flushed skin, punctuated by asymptomatic periods • 24-h urine test for catecholamines and metanephrine • Sympathomimetic drug use • Tachycardia, diaphoresis, and hypertension, with or without mental status changes. • cocaine, amphetamine; positive urine drug screen result

  26. Acute sympathetic crisis • The preferred initial treatment : IV benzodiazepine, such as lorazepam or diazepam • If first-line treatment is not successful •  nitroglycerin, phentolamine, or CCB (Nicardipine) may be used

  27. Acute sympathetic crisis • The use of b-blockers is not recommendedbecause unopposed b-blockade can cause alpha storm and increase cocaine toxicity • Most hypertension will resolve with time and benzodiazepines. • Watch respiratory rate.

  28. Brain Ct (C+/-)

  29. What is your interpretation? 這個檢查有改變你的想法嗎?

  30. 2013/09/23 10:32 (02:17) • T:36 P:89SBP:179 DBP:98 • Friends suggest without using of anti-hypertensive for five days • SBP: > 220mmHg at ER • CONSULT Dept 心臟內一科 Tm. 102/09/23 10:31 • Midazolan 5mg IV stat 

  31. 2013/09/23 11:57 CV consult sheet • Assessment:
1.Consciousness disturbance, cause? illicit-drug related?
2.HTN urgency
3.Hypokalemia • Plan:
1.Please rule out other possible etiologies of consciousness disturbance.
2.Control HTN with IV drugs if NO contraindications
3.Survey the etiology of hypokalemia
4.CCU admission if NO active CNS lesion; not suitable for ordinary ward.

  32. 2013/09/23 11:59 (03:44) • Admission to MICU2 2013/09/23 12:23 (04:08) • Acute respiratory failure • Midazolan 5mg IV stat • Rocuronium 50mg IV stat • On ETT 7.5 fix 22 with ventilator • On NG • CXR (B)

  33. MICU2 admission course • Midazolan line • Nicardipine line • NTG line • Consult NS • 9/25 Operation NS consult sheet: Acute hydrocephalus, rule out recent SAH/IVH, or infection related

  36. Discussion Hydrocephalus

  37. Hydrocephalus • Obstruction (most common): non-communicating • foramen of Monro, at the aqueduct of Sylvius, or at the fourth ventricle and its outlets • Impaired absorption (less common): communicating • Inflammation • Excessive production (rare)

  38. Hydrocephalus • Congenital hydrocephalus • Acquired hydrocephalus • Infection and tumor • Infection: bacterial/viral meningitis • Tumor: Posterior fossa medulloblastomas, astrocytomas, and ependymomas • Post-hemorrhagic • hemorrhage into the subarachnoid space or, less commonly, into the ventricular system • Low pressure hydrocephalus • Uncommon, extremely challenging to manage • result from tumors, chronic hydrocephalus, subarachnoid hemorrhage, and infections

  39. Post hemorrhagic hydrocephalus • The main mechanism for hydrocephalus is impaired absorption of CSF (communicating hydrocephalus) • CT demonstrated acute hydrocephalus less than or equal to 72 hours after SAH in 24 (23%) of 104 patients. • International Study on the Timing of Aneurysm Surgery. • 3521 patients • Hydrocephalus was diagnosed on admission computed tomographic (CT) scans in 15% of patients and was thought to be clinically symptomatic in 13.2% of patients. There was a 5.9% overlap between these groups.  Hasan, D., Lindsay, K. W., & Vermeulen, M. (1991). Treatment of acute hydrocephalus after subarachnoid hemorrhage with serial lumbar puncture. Stroke, 22(2), 190–194. doi:10.1161/01.STR.22.2.190 Graff-Radford NR, Torner J, Adams HP, Jr, & Kassell NF. (1989). Factors associated with hydrocephalus after subarachnoid hemorrhage: A report of the cooperative aneurysm study. Archives of Neurology, 46(7), 744–752. doi:10.1001/archneur.1989.00520430038014

  40. Subarachnoid hemorrhage • Hydrocephalus is a common complication of SAH • Drainage should be considered for patients who have a deteriorating level of consciousness and for those in whom no improvement in hydrocephalus occurs within 24 hours • Earlier reports suggested that the frequency of rebleeding was increased with external ventricular drainage for acute hydrocephalus after aneurysmal SAH • these studies had methodologic limitations, and later reports have found no association of external drainage with the risk of rebleeding

  41. Take home message • Acute Hydrocephalus is an indirect sign of SAH • Diagnosis of hypertensive encephalopathy shall be made after excluding intracranial lesion • Seek second opinion of image study
