cyanide, hydrogen sulfide, CO

3

seizure & death causes

over dose of antidepressants, isoniazid, diphenhydramine, cocaine, amphetamine

4

Tylenol OD effect

massive hepatic necrosis 48-72 hr post ingestion

5

thiamine and glucose for...

wernick's encephalopathy and hypoglycemia

6

narcotic antagonist (narcan) for...

narcotic OD

7

flumazenil for....

benzo OD (but careful if TCAD, seizure d/o, or benzo dependence, bc can cause seizures)

8

HTN and tachycardia typical with...

amphetamines, cocaine, anticholinergics

9

hypotension and bradycardia typical with...

CCB, Beta blockers, clonidine, sedative hypnotics

10

hypotension and tachycardia typical with...

TCAD, trazodone, quetipine, vasodilators, beta agonists

11

rapid respirations typical with...

salicylates, CO

12

hyperthermia typical with...

anticholinergics, salicylates, drugs producing seizures

13

horizontal nystagmus typical with...

sedative hypnotics, phenobarbital, phenytoin, EtOH

17

vertical and horizontal nystagmus typical with...

PCP

18

ABG looks at...

oxygenation (low PO2 and high PCO2 is failure)
pH (acidosis = poor perfusion)

19

electrolytes look at...

potassium
anion gap

20

serum osm looks at...

chemicals dissolved in blood. Works for sodium, chloride, bicarb, proteins, sugar.

21

digoxin

24

Ipecac instructions

w/in 30 min w 8 oz water. Only if poison control says so.

25

Ipecac contraindications

corrosives, petroleum-based, rapid acting convulsant

26

activated charcoal use

Most helpful (but not w corrosives)

27

Urinary alkalinization (Sodium bicarb IV) use

if toxic substance is weak acid (phenobarbital or ASA). Enhances elimination.

28

dialysis use

for ethylene glycol, methanol, EtOH, lithium, ASA, theophylline

29

kids: 150-200 mg/kg
adults: 7g

30

APAP antidote

N-acetyl-cysteine

31

anticholinergic OD tx

supportive, sedation

32

anticholinergic antidote

physostigmine (give carefully and not with TCAD)

33

TCAD antidote

sodium bicarb

34

ASA max dose

> 200 mg/kg

35

ASA OD tx

gastric lavage, activated charcoal.
IVF, IV sodium bicarb
Maybe dialysis if severe toxicity

36

beta blocker OD tx

glucagon

37

CCB OD tx

calcium

38

cyanide antidote

activated charcoal
nitrates
hydroxycobolamin

39

ethylene glycol (antifreeze) antidote

fomepizole (inhibits alcohol dehydrogenase)

40

methanol antidote

fomepizole
(same as ethylene glycol)

41

ethanol OD tx

supportive (IVF)
dialysis if severe

42

benzo antidote

flumazenil (not good if benzo dependent)

43

Hydrocarbon tx

resp support

44

iron antidote

deferoxamine (desferal)
