Flashcards in Emergency Medicine Deck (31):
1

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

2

Parkland Formula

4xKGx %BSA
give 50% for 8 hr remaining 50% over the following 16 hours.

3

the 5 W of posoperative fever

Wind:atelectasis,pneumonia
water:ITU
wounds:wound infection,abscess
Walking:DVT
Wonder drugs: drug reaction
womb:endometritis

4

hypertermia

>40C or 104F>

5

shock types with increase PCWP

CARDIOGENIC
-chf
-arrythmia
-structural heart disease
OBSTRUCTIVE
-cardiac tamponade
-tension pnuemotorax
-massive pulmonary embolism

6

contraindications for gastric lavage

altered metnal status
caustics
acetaminophen averdose

7

benzodiazepine overdose

DO NOT GIVE FLUMAZENIL(can cause seixures)

8

toxic dose of acetaminophen

8-10gr

9

faltal dose of acetaminophen

12-15gr.

10

carbon monoxide results in PO2

NORMAL PO2 because oxygen does not detach from hemoglobin, also in methemoglobin

11

most accurate test in CO poisoning

carboxyhemoglobin level

12

acid-base distrubance in CO poisoning

metabolic acidosis

13

causes of methemoglobinemia

benxocaine
nitrites and nitroglycerin
dapsone

14

best initial treatment for methemoglobin

100% oxygen

15

most accurate treatmetn for methemoglobin

methylene blue

16

electrolite anormality associated with increase risk for digitalis toxycity

hypokalemia

17

strongest indication for digoxin-binging antibodies

CNS and cardiac involvement

18

nausea,vomiting, hyperkalemia,yellow halos around objects

digoxin toxicity

19

iron chelators

succimer(ORAL)_
ethylendiaminetetraacetic acid(EDTA)
dimercaprol(BAL)

20

mercury chelator

diMERCaprol
succimer

21

treatmetnn for alchohol intoxication

fomepizole
-ONLY dialysis is going to remove the alchol.

22

snake bite

pressure,inmmobilization, antivenin

23

trauma andLoss of conciousness

DO A CT with out contrats

24

best inital step in hypotermia

EKG(J WAVES)

25

drowning

NO STEROID NO ANTIBIOTIC

26

VF

shock,drug,shock,drug and CPR at all times in between the shocks

27

pulseless

VF
VF
asystole( give CPR and epinephine)
Pulseless electrical activity

28

irregularly irregular rhythm

atrial fibillation

29

hemodynamically unstable with atrial arrhythmia

synchronized cardioversion(if chornic ANTICOAGULATE before cardioversion)

30

standar of care for atrial fibrillation

rate control and anticoagulation
-CHADS 1 or less=ASAS
-CHADS 2 or more=warfa,dabigatran,rivaroxaban or apixaban

31

most accurate test for WPW

electrophysiology studies
