vasopressors

Question 1

Phenylephrina

Answer 1

• stimulates alpha 1 - increases the afterload , causes pulmonary vasoconstriction

Question 2

Norepinephrina

Answer 2

• cel mai important - pe receptorii alpha dar putin si pe beta
• socul septic si nediferentiat
• poate da vasoconstrictie daca extravazeaza

Question 3

Adrenalina

Answer 3

concentratii mici - efect pe receptorii beta
concentratii mai mari - si pe alpha - vasoconstrictie
bine tolerata daca extravazeaza
creste lactatul

Question 4

socul cardiogenic

Answer 4

debitul cardiac = minut volumul x frecventa cardiaca
av scazuta :isoproterenol cel mai eficient ptr a creste FC dar scade tensiunea
ptr actiune inotropa : dobutamina
daca amandoua :adrenalina

Question 5

socul distributiv

Answer 5

hipovolemie - sunt scazute atat intoarcerea venoasa cat si postsarcina
soc distributiv :intoarcere venoasa buna,postsarcina scauzuta
CAT :fluide iv
vsopresoare
Norepinefrina e preferata
alternative : fenilefrina - dar creste rezistenta pulmonara , scade presarcina
vasopresina
angiotensina 2 - super la pacientii cu ieca

Question 6

which is the target cardiac frequency for valvular lessions

Answer 6

stenotic lesions - target low cardiac rate

regurgitant lessions - target high cardiac rate
