How serious is hemorrhagic stroke in Taiwan?
About 73 per one hundred thousand occur each year 22% in all stroke 30 days mortality: 26-30% The first leading cause of serious long-term disability in adults Before my topic, let me show how serious is hemorrhagic stroke in Taiwan. Generally, there is 73 per patients in hemorrhagic stroke at Taiwan each year. Hemorrhagic type stroke accounts for 22% of all strokes a d is associated with higher mortality rate than cerebral infarctions. The 30 days morality rate is up to 30%. It is also the first leading cause of serious long-term disability in adults in Taiwan. Taiwan Guidelines for the Management of Stroke 2008

ICP monitor placement 置放ICP monitor,協助歸零校正,並記下序號 貼在機身及ICP線上,勿拉扯
67
ICP monitor placement
68
ICU病人請每天記錄GCS, muscle power及病人原有的neurologic sign的變化，注意I/O (若沒有特殊因素, 維持約+500ml/day, Aneurysm clipping術後為預防vasospasm, +500~1000ml/day), 每天check X-ray, electrolyte, ABG等data
69
ICU病人請每天記錄GCS, muscle power, pupil size & reflex (brain surgery or head trauma), 或muscle power& DTR (spine surgery or trauma) 及病人原有的neurologic sign的變化
70
GCS change 一般而言指的是motor下降了兩分以上, Pupil size or reflex有改變, 或其他變化, 要做以下處理
Systemic problem Focal neurologic problem (通常伴隨pupil size or reflex改變, seizure, or IICP)
71
顱內出血患者發生意識狀態改變？ 延遲性出血 (Delayed hemorrhage) 腦水腫(Cerebral edema)
癲癇(Posttraumatic seizure) 水腦症(Hydrocephalus) 代謝性問題Metabolic abnormalities ( e-, gas ) 感染Infection ( meningitis, abscess ) 其它部位受傷Associated injury ( shock, spine )
72
Systemic problem Airway有無問題
Check ABG有無CO2 retention, acidosis, hypoxemia 體溫有無發燒, 有無sepsis sign Check electrolyte注意有無electrolyte imbalance Check sugar注意有無hypo- or hyperglycemia Check CBC注意有無anemia
73
Focal neurologic problem
通常伴隨pupil size or reflex改變, seizure, or IICP Brain CT, 通常non-contrast即可, 緊急時請打電話連絡CT room 連絡當天值班的神外醫師
74
IICP的處理 頭高30度, 增進venous return
Hyperventilation: 適用已intubation的病人, keep PaCO2 30~35mmHg (注意! 只適用短時間, 時間一久, vasoconstriction, 反而引起ischemic change) Hyperosmotic agent: 降ICP效力Glycerol < Mannitol < 3% NaCl CSF drainage: 對於有ventriculostomy的病人可以使用, prn放CSF 5 cc Barbiturate coma: Pentothal 3~5mg/kg/hr *24hours then 2.5mg/kg/hr Craniectomy
75
Mannitol Loading：以60Kgw為例，相當於75-120g，可打1-2瓶 每天劑量：300-1000ml
考慮rebound phenomenon, 是否準時給藥，給藥方便性 75ml Q4h 100ml Q4h 100ml Q3h 150ml Q3h 60g/300ml/btl 作用開始：30-60 mins 作用時間：6-8 hours 半衰期： mins Loading: g/kg infused 成人一般劑量 g/24hours 給藥速率：drip 30-60min (勿全速給藥）
76
Glycerol Post concussion syndrome Minor head injury
成年人一般劑量250cc，間隔４小時以上 內含５％ fructose，糖尿病人使用要注意 注射太快可能導致溶血
77
Pentothal Barbiturate Coma Pentothal (500) 5Amp in N/S 100 cc Protocol
Loading: 10 mg/Kg IV x 4hrs （24cc/hr ) Maintain: 1 ~ 1.5mg/Kg/hr ( 2.4 ~ 10cc/hr ) 目標：Pentothal level 3-5 mg% & ICP < 24 mmHg 若ICP小於20mmHg， 續用48hrs 再taper Pentothal
78
Drain tube V/B, J-vac, Hemovac 美式引流袋
79
V/B, J-vac, Hemovac 一般是放在epidural space或是subgaleal layer, 除非是chronic SDH的病人會放在subdural space, 就在brain的表面, 所以不可壓, 否則會造成acute SDH, 若不確定看op note或詢問operator 放在epidural space or subgaleal layer術後一定要壓, 製造vacuum的效果, 同時要q1h milking, 避免術後產生EDH 常見的craniotomy或craniectomy術後第一天的引流量約 cc, 如果都沒有什麼量流出來, 要檢查有無阻塞, 小心術後發生EDH 有一種情況要改成不壓: 若是術後幾天流出來的fluid 顏色變淡, 類似CSF, 請改成勿壓
80
引流管 Drainage Tube
81
Chronic SDH (慢性硬腦膜下出血)
Risk factor: old age, brain atrophy, coagulopathy Vaccum ball (VB) 勿壓 (硬腦膜下引流管) 平躺, 多喝水, 不用Mannitol
82
VB可不可以壓? Epidural Subdural drainage ( CSDH )
83
美式引流袋 接EVD用的收集袋, 可同時調整高度決定引流量與監測ICP
Ventriculostomy: EVD tube放在lateral ventricle裡, 可引流CSF, 可監測ICP Cisternostomy: EVD tube放在cistern裡
84
External Ventricular Drainage ( EVD ) ( 腦室引流管 )
85
Dysfunction 當monitor上的wave form消失或數字有疑問時, 依序檢查: 管路有無打折, 控制閥是否關閉 重新歸零
將收集瓶放到低於耳洞的高度, 檢查管線內液體是否會流動: 會: 表示ventriculostomy是通的, 只是裡面的CSF不多 不會: 表示管路阻塞, 請通知當天值班的神外醫師
86
CSF收集瓶 注意事項: CSF 引流的量 CSF 顏色 引流瓶通引流袋的卡夾 CSF收集袋
87
藥物的使用 腎功能不好的病人儘量不要使用mannitol, Euglucon, Glucophage, Gaster, or muscle relaxant等 HTN的病人在ICU盡量以短效的藥物為主, 病房則以長效的為主, 常用的藥物如Norvasc¸ long-acting ACEI都需要3 天以上藥量的loading, 不適合用於ICU緊急的病患 Steroid適合用於 vasogenic brain edema, 例如brain tumor引起的perifocal edema, 至於在trauma上並沒有證實有效, 除了central cord syndrome Phenytoin (Dilantin) or Valproate (Depakine): 對於severe brain injury, 特別是temporal lobe injury 有預防early post-traumatic seizure的效果
88
藥物的taper 視病人的病情而定, 如果在taper過程中consciousness有改變, 請回到前一個dose
對elective的病人, 若術前brain swelling不是很厲害, conscious clear,可以在用滿3天後開始taper, 然後一天一個dose 對於trauma的病人, 通常在3-5天可能有delay hemorrhage or perifocal edema, 所以taper的時間要延後, 可以從5-7天之後再開始, 2天一個dose 如果是pure EDH, 而且術後conscious clear, 可以早一點taper
89
Mortality 若有病人病情惡化, AAD, 死亡, 連絡當天值班的神外醫師
