Q

what causes hypercoagulability in prego?

A

increase clotting factors, decrease PC/S and INCREASED FIBRINOGEN*if you ever see normal fibrinogen in prego especially close to term think DIC.

Q

Precutaneous Umbilical Blood Sampling(PUBS)/Cordocentesis. why do you do this? when?

A

anytime between 20-32 wks to confirm fetal anemia & treat w/transfusion.*if >32 wks = deliver baby!

Q

Misoprostole vs Mifepristone?

A

Misoprostole(PGE1) = causes uterus to contract ad expel productsMifepristone(–|PG) = causes trophoblast to be removed from the decidua = terminates prego

Q

CST early decelerations

A

normal or head compression

34
Q

antenatal testing hierarchy…

A

NST > BPP then if 0-2BPP = fetal demise = deliver now! if 8-10BPP = normal, if 4-6 BPP:>36wks = delivery<36wks –> contraction stress testCST: no late decel, no brady = stop inducing contraction leav baby in!CST: late decelerations, brady = fetal demise deliver!

35
Q

whats the target BP in prego women?

A

BP <140/80

36
Q

what happens in prego with renal shit?

A

increase in GFR, decrease in Cr

37
Q

How do you test for gestational DM? when?

A

third trimester.-1h glucose: +>140-3h glucose: + if fasting >95, 1h>180 2h>155 3h>140

38
Q

Define Preterm deliverymanagement?

A

20-34 wks<20 = abort>34 deliver20-34 depends! as long as no C/I = steroids + Tocolytics to help lungs mature! *will only last a day or so

39
Q

Preeclampsia with severe features

A

> 160/110 + Proteinuria + any 1 of: Cr>1.1, Plt<100, elevated liver enzymes, RUQ pain, Pulmonary edema, HA or visual disturbances*basically its gonna look like help but its missing all aspects of help**can sometimes induce for vag delivery with this but often do C-section

40
Q

what is prolonged rupture of membranes? managment?

A

> 18 hr ROM *risk for GBS, Chorioamnitis(baby still in infect), endometritis(baby out inf)tx: Ampicillin + Erythromycin

41
Q

Tx of chorioamnionitis and endomeritis

A

clindamycin +gentamicin + ampicillin

42
Q

define rupture of membranes

A

ROM + contraction between 37-42 weeks

43
Q

If you have arrest of labor in stage 2 and you ahve already given oxytocin what do you do?

A

operation vaginal delivery > c-section*vacuum assited or forcepts

44
Q

If you have labor arrest in stage 1 active and they tell u contractions are adequate….what do you do?

A

C-section! if not adequate give oxytocin!

45
Q

whats the thinking behind a NST?

A

baby moves = increase in baby hr! –> you want to see accelerations & variability

46
Q

when can you do amniocentesis? why?

A

> 16 wks to look for genetic defects. low risk to baby but not really done anymore bc if defects you basically only get 2-3 weeks to decided if u wanna keep it or not =/ been replaced with CVS and quad

47
Q

HTN in prego?

A

140/80

48
Q

when measuring fetal station what is 0?

A

ischial spine

49
Q

frank breech

A

legs up in air

50
Q

Nuchal Translucency(NT) When is this done? whats normal?

A

1st trimester(10-13w) - should be <3mm if more could indicate trisomy defect

51
Q

when do you do MCA doppler? what does this telll u about the baby?

A

> 20 wks. “water flows faster than ketchup”*high diastolic = anemia

52
Q

Triple Screen Vs Quad screen when are they done? why?

A

both in 2nd trimester(15-22wks) to id genetic disorder esp trisomies. x3 = AFP, hcg, Estriolx4 =AFP, Estriol, INHIBIN, Bhcg**18 all down, 21 has h*I up!

53
Q

What is an adequate contraction? how can you tell?

use IUPC –> 200 mV in 10 min or 3 in 10 min that feel strong!

54
Q

tx of HTN in prego?

A

alpha methyl dopa, labetalol, hydralazine,

55
Q

CVS. when do you do this? why?

10-13 wks(1st trimester), checks for genetic abnormalites! = good bc can be done early = make decision earlier. 0.22% loss

56
Q

what causes effacemnt of the cervix?

A

prostaglandins E2 can use topically to ripen cervixthis is why indomethacin can be a tocolytic

Q

CST variable decelerations

A

cord compression

58
Q

Tx of UTI in prego
