Emergency Medicine Flashcards
causes of PEA(pulseless Electrical activity)
5H´s
5T´s
NORMAL EKG and NO PULSE
hypovolemia hypoxia hydrogen ion:acidosis hyper/hypo: K, hypotermia tablets: drug overdose,ingestion tamponade tension pneumotorax thrombosis:coronary thrombosis:pulmonary embolism
Parkland Formula
4xKGx %BSA
give 50% for 8 hr remaining 50% over the following 16 hours.
the 5 W of posoperative fever
Wind:atelectasis,pneumonia water:ITU wounds:wound infection,abscess Walking:DVT Wonder drugs: drug reaction womb:endometritis
hypertermia
> 40C or 104F>
shock types with increase PCWP
CARDIOGENIC -chf -arrythmia -structural heart disease OBSTRUCTIVE -cardiac tamponade -tension pnuemotorax -massive pulmonary embolism
contraindications for gastric lavage
altered metnal status
caustics
acetaminophen averdose
benzodiazepine overdose
DO NOT GIVE FLUMAZENIL(can cause seixures)
toxic dose of acetaminophen
8-10gr
faltal dose of acetaminophen
12-15gr.
carbon monoxide results in PO2
NORMAL PO2 because oxygen does not detach from hemoglobin, also in methemoglobin
most accurate test in CO poisoning
carboxyhemoglobin level
acid-base distrubance in CO poisoning
metabolic acidosis
causes of methemoglobinemia
benxocaine
nitrites and nitroglycerin
dapsone
best initial treatment for methemoglobin
100% oxygen
most accurate treatmetn for methemoglobin
methylene blue
electrolite anormality associated with increase risk for digitalis toxycity
hypokalemia
strongest indication for digoxin-binging antibodies
CNS and cardiac involvement
nausea,vomiting, hyperkalemia,yellow halos around objects
digoxin toxicity
iron chelators
succimer(ORAL)_
ethylendiaminetetraacetic acid(EDTA)
dimercaprol(BAL)
mercury chelator
diMERCaprol
succimer
treatmetnn for alchohol intoxication
fomepizole
-ONLY dialysis is going to remove the alchol.
snake bite
pressure,inmmobilization, antivenin
trauma andLoss of conciousness
DO A CT with out contrats
best inital step in hypotermia
EKG(J WAVES)
drowning
NO STEROID NO ANTIBIOTIC
VF
shock,drug,shock,drug and CPR at all times in between the shocks
pulseless
VF
VF
asystole( give CPR and epinephine)
Pulseless electrical activity
irregularly irregular rhythm
atrial fibillation
hemodynamically unstable with atrial arrhythmia
synchronized cardioversion(if chornic ANTICOAGULATE before cardioversion)
standar of care for atrial fibrillation
rate control and anticoagulation
- CHADS 1 or less=ASAS
- CHADS 2 or more=warfa,dabigatran,rivaroxaban or apixaban
most accurate test for WPW
electrophysiology studies
