Hx, PE and Labs 
   Vital signs; Cirrhosis?NSAID?; Med?,HR(BB?); conjunctiva
   CBC+BCS(bili)+PT/aPTT+ABO/Rh &Cross; A級領血(O) 
Management
   Resuscitate with Crystalloid first!  Keep vital signs
   If cold sweat/shock→ICU ; correct PLT/PT/aPTT, Reversal
   PPI+ Terlipressin if unstable UGI; DDAVP+cryo if uremic
   EGD if massive; CTA+embolization LGI ; consult surgeon

## Hypertension
排除中風!有原因? Signs of emergency? + → Treat IV
Lethal etiology
   ICH/stroke, HTN emergency, Pheochromocytoma, HELLP
Hx, PE and Labs 
   Pain?Stress?Med? Signs of TOD,5P for Pheo, focal signs? 
   NE: EOM, tongue, FNF, pronator ; BCS(organ damage)
Management
   Use labetalol or nicardipine if TOD+ ; ↓20% in hours
   Pain control and treat stress first!
   Use amlodipine if TOD- and no signs of stroke
   Doxazosin if Pheo; CT/Neuro if suspected ICH/stroke
   
## Hypertension
Sugar
AMS→check F/S; Cause?(INF,med); watch out HHS/DKA!  
Lethal etiology
   Hypoglycemia(mins), HHS/DKA(hours), euglycemic DKA
Hx, PE and Labs 
   Vital signs, Drugs?  F/S! ↑CBC+BCS+blood sugar, AG(+Cl)
   HHS/DKA→ Insulin, Iatro, Inf, Infarct, Ischemia, intoxic
Management
   D50W 2-3 amp ± D10W 500ml for Hypoglycemia→ F/U
   Insulin(Sliding scale)+ cause solving for Hyperglycemia
   Check CBC/BCS+osmo+AG+ketone(AC-AC) if Sugar↑+怪
   Insulin+IVF+K if DKA/HHS→ F/U Na/K/AG  直到AG正常
   
## Sugar
- hypoglycemia 或 hyperglycemia都可能讓病人悲劇
- hypoglycemia:最常見，冒冷汗，意識不清 (常見清晨，病人未吃飯時)-> one touch -> D50W 兩隻直接打，一小時後recheck

- hyperglycemia: 通常大於500 insulin打不下來要小心
- 伴隨意識喪失時，要想到HHS, DKA
- 在矯正時，使用insulin pump，同時注意病人Na,K濃度(使用insulin pump需要將病人轉至加護病房)

## Allergy/Angioedema
Maintain CAB, IV/O2/Monitor; Epi 0.5mg IM if unstable  
Lethal etiology
   Anaphylactic shock, vocal cord edema, bronchospasm
Hx, PE and Labs 
   Vital signs + SpO2 + Conscious; Drugs?→DC, Food?
   No useful tool to determine(tryptase?); Types of allergy
Management
   Epinephrine 0.5 mg IM(not IVP) if unstable vitals/CAB
   IVF + Epi 6 mcg/kg/hour if persistent shock → ICU
   Steroid + anti-histamine(H1+H2); Biphasic reaction
   Beta2-agonist INH if bronchospasm, ± Intubation
Allergy
Bone/Joint/Back Pain
在止痛前先弄懂為什麼會痛! 排除致命原因  
Lethal etiology
   Aortic dissection, AAA, Septic joint, cord compression
Hx, PE and Labs 
   Trauma?Tumor?Organ? previous pain killer, vital signs, 
   rash(VZV); ±CBC/DC+BCS, ±plain film, Echo; Cord→ MRI
Management
   Watch out for possible lethal cause!  Pain score or VAS
   Treat with Scanol/NSAID/tramadol/morphine/steroid 
   講求藥效前先求不傷身體! By oral/clock/ladder
   NSAID的禁忌症: CKD,peptic ulcer,CHF,Cirrhosis,Allergy
   
## Pain
***排除致死原因前勿隨意止痛
- 胸痛：AMI, AA
- AMI:左胸，左肩，左背，有時候左上腹鈍痛，胸悶，像被石頭壓住，冒冷汗
- AA：刺痛，前胸痛後背，如果是血管破裂，疼痛分數可以瞬間從0-10分，會記得疼痛瞬間在做的事情

- 腹痛：AAA, holo organ perforation, ischemic bowel
- red flag: peritoneal sign, 如果有的話，至少KUB看free air，可以考慮切CT


## Nausea & Vomiting
需先排除Acute abdomen/ischemic bowel; IICP? AMI?
Lethal etiology
   Acute abdomen, ischemic bowel, IICP,AMI, brain stem
Hx, PE and Labs 
   Associated s/s; Drugs(chemo)? Focal signs? Abd PE ±NE 
   Preg? F/S,BCS, KUB±CTA, EKG if old/non-specific, 眼底鏡
Management
   Always find the etiology first! ; NGD if obstruct
   Primperan(avoid obstruct); novamin; vena if peri-Vertigo
   Granisetron; Emend/Olan/steroid/Ativan if Chemo 
   Monitor F/S and taper DM medication

## Insomnia
先查清楚為什麼會失眠? 一夜失眠不會有事! 呼吸   
Lethal etiology
   ICH, stroke, hypoxia, CO2 retention ,delirium(+its cause)
Hx, PE and Labs 
   Associated s/s; Vital signs, orient?, respiratory pattern
   ±essential NE; CBC/BCS+ABG±brain CT if 怪
Management
   不確定安不安全就不要給安眠藥! 病人之前用過?
   careful using BZD if delirium(except delirium tremens)
   萬用Ativan, may use Zolpidem/Brotizolam/Triazolam
   Avoid Vena for insomnia
   
## Delirium

   Always exclude lethal cause first! 
   Scanol or NSAID if tension headache or migraine
   No effective medication for dizziness; may try Anti-His
   Diphenidol if vertigo; may use vena if still vertigo(±MRI)
   
## Dizziness
- 排除central cause
- 小心focal neurologicala sign或是IICP sign
- NE做完正常就症狀控制 

## Input & Output; U/O
學會辨認volume status!  Pos: 喘不喘? Neg: 乾不乾?
Lethal etiology
   Heart failure, impending shock, AKI+hyperkalemia, Sepsis
Hx, PE and Labs 
   Drugs? I/O last days; JVD, rales, edema; Echo: IVC+Lung
   U/O↓ Echo(bladder+ΔIVC), ±CBC/BCS/HCO3/K/lactate
Management
   Echo can help!  Bladder, IVC, heart(RV, LVEF), lung B-line
   I/O(+): Input↑+喘=Lasix ; Output↓+喘= 先survey ±lasix
   I/O(-): Input↓+乾=IVF; Output↑=Med/Ca/DI/DM/postAKI

## Urine output
   decreased urine output -> 從post renal cause 開始診斷
                          -> bladder sono, r/o acute urinary retension -> foley
                          -> 水太少-> 給水
                          -> 最後才考慮給利尿劑
