1

gastric lavage useful in....

1 hour of ingestion

2

ALL types of gastric emptying are dangerous in

1. caustic ingestion
2. altered mental status
3. acetaminophen overdose

3

ALWAYS WRONG ANSWER GIT emptying...

1. ipecac
2. cathartics
3. diuresis: fluids and diuretics
4. whole bowel irrigation

4

ipecac

prior to coming to hospital

5

cathartic agents=

sorbitol
does NOT eliminate ingestion without absorption

6

diuresis=

pulmonary edema

7

only times whole bowel irrigation is correct

1. massive iron ingestion
2. lithium
3. swallowing drug filled packets

8

not clear what cause of OD is, go with..

acetaminophen or
aspirin

(since mcc death from OD)

9

patient with altered mental status and unknown cause order of steps

1. naloxone and dextrose
2. intubation
3. gastric lavage

10

chronic benzo user given flumazenil

INSTANT WITHDRAWAL--> seizures

11

first time benzo use and TCA

benzos PROTECT from TCA induced seizures

12

first time benzo use and TCA and give flumazenil

flumazenil removes the protection from seizures by benzzos--> SEIZURES

13

opiate OD vs benzo OD

opiate= fatal
benzos= non fatal (DO NOT GIVE FLUMAZENIL)

14

charcoal use

ANYONE with pill OD, not dangerous, and not specific

15

charcoal in comparison

BETTER than lavage and ipecac

16

don't know what to do in toxicology give....

CHARCOAL

17

what scenario when less acetaminophen is needed to cause toxicity

ALCOHOLICS

18

toxic amount of acetaminophen ingested (8-10grams)

N-A-C

19

OD acetaminophen more than 24hrs ago

NO TX

20

amount of ingestion of acetaminophen is unclear

DRUG LEVEL

21

ok to give both NAC and charcoal

YESSS it is

22

PC aspirin OD

- tinnitus
- hyperventilation
- resp alkalosis ---> metabolic acidosis

23

why metabolic acidosis in aspirin OD

aspirin messes with ox phos--> anaerobic--> lactic acidosis

24

blood gases for aspirin OD

low O2
low bicarb
HIGH PH

25

best initial test for someone with TCA ingestion after given antidotes...

EKG

26

what are you looking for on EKG with TCA OD

TdP---> WIDENING of QRS

27

serious consequences of TCA OD

seizures
arrhythmia

28

bicarb use in TCA OD

protects from arrhythmias
DOES NOT increase urinary excretion

29

caustics

acids and alkalis (drain cleaner)

30

caustics cause....

mechanical damage to oropharynx, esophagus, stomach--> PERFORATION
