methoxyflurane
HIS MED

Question 2

List all the IV anesthetics

Answer 2

barbituates
propofol
ketamine
etomidate

Question 3

Define the MAC

Answer 3

concentration that results in IMMOBILITY in 50% of paitents when exposed to a noxious stimulus such as surgical incision
IMMOBILITY MAC

Question 4

Low MAC = ?

high MAC = ?

Answer 4

low MAC (requires little of the substance to make people not move when they feel pain) = potent`
high MAC = low potency

Question 5

how do you measure the potency of an anesthetic?

Answer 5

liposolubity ie a high oil:gas partition coefficient bc htat means more of it is lovin the fatty oil

Question 6

Two measurements of potency adn their relationship

Answer 6

increased oil: gas = low MAC = POTENT

Question 7

blood:gas parittion coefficient measures?

Answer 7

latency to onset
HIGH - later onset

LOW - quicker onset

Question 8

anesthetics with a large oil:gas have a large blood:gas

Answer 8

yep. thats a thing.

Question 9

how does ventilation affect arterial tension of anesthetic

Answer 9

if have a low blood:gas then will cause only slight increased in arterial tension

if have a high blood: gas then will cause a sig increase in arterial tension

Question 10

What determines the ateriovenous concentration gradient?

Answer 10

depents on the uptake at the tissue, and slows down the onset

Question 11

Elimination for low blood and tissue solubility

Answer 11

mirrors anesthetic: easy transport in and out

Question 12

elimination for high blood and tissue solubility

Answer 12

depends on duration of anesthetic - bc gotta get ride of all the anesthetic in the blood and tissues that has been shoved in there the whole time

Question 13

~*~Which inhaled anesthetics cause decreased BP due to affects on myocardium

Answer 13

halothane

enflurane

Question 14

~*~Which inhaled anesthetisc cause decreasedp BP due to affects of TPR?

Answer 14

isoflurane
desfulrane
sevoflurane

Question 15

~*~Which inhaled anesthetics are preferred in peopel with heart problems?

Answer 15

isoflurane
desflurane
sevoflurane

bc dont affecy myometrium

Question 16

Who is pungent?

Answer 16

Isoflurane and Desfluraose

DES Is so pungent

Question 17

Who is not pungent

Answer 17

halothane
sevoflurane
NO

Question 18

Most likely to cause respiratoroy depression

Answer 18

isofulrane
enflurane

the vowels cause respiratory depression

Question 19

Who causes tonic clonic movements

Answer 19

enflurane

Question 20

hepatotoxicity

Answer 20

halothane

Question 21

nephrotoxicity

Answer 21

methoxyflurane

Question 22

causes malignant hypertension

Answer 22

succinylchline and halothane

Question 23

treat my malignant hypetension

Answer 23

dantrolene

Question 24

hematotoxicity

Answer 24

N2O - decreases methionine synthase activity = megalblastic anaemia

DENTISTS

Question 25

what is used for induction fo anesthesia AND short surgical procedures

Answer 25

thiopental methohexital ultra short acting barbituates

Question 26

describe effects of the ultrashort acting barbiturates

Answer 26

decreased ICP do not produce analgesia cause hyperalgesia

Question 27

tell me abotu propofol

Answer 27

antiemetic induction and maintenenace of analgesia potent respiratory depression (iso and enflurane) reduced ICP causes hypotension via PVR

Question 28

Who cares abtou Etomidate

Answer 28

used for anesthetic induction at patients at risk of hypotension minimal cardio and resp no analgesic decreases ICP n/v inhibit steroidogenesis decreases plasma hydrocortisone

Question 29

ketamine

Answer 29

increased ICP EMERGENCE PHENOMENA: causes sensory and perceptual illusions = treat with diazepam, midazolam, propofol

Question 30

How do I make neurolept analgesia happen?

Answer 30

with fentanyl - shor acting opiod and droperidol

Question 31

how do i man neurlept analgesia become anesthesia

Answer 31

fentanyl and droperidol TH`EN add N2P in )2

Question 32

why would we add in some benzo?

Answer 32

to forget the horrors no anxiety and anterograde amnesia

Question 33

what would you give so people donet puke?

Answer 33

oh-danse-etron

Question 34

what benefits would scopolamine offer? antimuscarinic ;)

Answer 34

amnesia - forget it all wtih benzos no salivation no bronchial secretions protect heart from bradycardia
