Flashcards in Tuesday, 2-28-Medical conditions in pregnancy (Wootton) Deck (34):
1

when do you screen for Gestational DM? How do you screen?

24-28 weeks

50 gm 1 hr oral load glucose challenge test --> if abnormal followed by a 3 hr 100 gm oral load glucose tolerance test

2

risk factors for GDM development?

-fat
-previous hx of GDM
-strong FH of DM
-known glucose intolerance

3

maternal complications of GDM?

-increase risk of gestational HTN
-increased risk of preeclampsia
-greater risk of C section
-increase risk of developing diabetes later

4

fetal complications of GDM?

-MACROSOMIA
-neonatal hypoglycemia
-hyperbilirubinemia
-operative delivery
-SHOULDER DYSTOCIA
-birth trauma

5

maternal complications of Pregestational diabetes?

worsening nephropathy and retinopathy, increased risk of developing preeclampsia, greater risk of DKA

6

fetal complications from pre gestational diabetes?

increase risk of spontaneous abortions, anatomic birth defects (sacral agenesis), fetal growth restriction and prematurity

7

with good glycemic control, fasting glucose should be less than __ mg/dl, 2 hour postprandial glucose less than __ mg/dl

fasting < 90

2 hr postprandial <120

8

maternal evaluation for antepartum mgmt of preexisting diabetes?

renal-24 hr collections every trimester
cardiac-EKG
ophthalmic-detailed eye exam in 1st tri
glycemic control-monitor daily fingerstick glucose values and HgBA1C

9

fetal evaluation for anterpartum mgmt of preexisting diabetes?

early dating US
BCHEM testing for congenital malformations at 16-20 wks
fetal testing (NST/BPP) every week starting 32-34 wks

10

at what US-estimated fetal weight would you want to recommend caesarean delivery?

4500 gm

11

how to dx maternal hyperthyroidism?

elevated free T4 and suppressed TSH

12

When to use methimazole and/or PTU for maternal hyperthyroidism?

methimazole in 2nd and 3rd trimester --> can cause aplasia cutis and choanal atresia in 1st tri

PTU in 1st trimester only --> increased risk of liver toxicity if beyond 1st tri

13

monitor levels of what throughout pregnancy with maternal hyperthyroidism?

TSH

14

signs and symptoms of thyroid storm? tx?

s/s: hyperthermia, tachy, perspiring, high CO failure, maternal mortality rate of ~25%

tx: B-blockers (propanolol)), block secretion of thyroid hormone (Na iodide), stop synthesis of thyroid hormone (PTU), halting peripheral conversion of T4 to T3 (dexamethasone), replace fluid loss, bring temp down

15

increased risk associated with untreated maternal hypothyroidism? tx? monitor what monthly?

increased risk:
spontaneous abortion
preeclampsia
abruption
low birth weight infants
stillbirth
low intelligence

tx: thyroid replacement, i.e., Levothyroxine

monitor TSH and free T3/4 levels monthly

16

result of neonatal hypothyroidism?

deficiency results in generalized developmental retardation

17

flares of SLE tx with? fetal complications?

tx with prednisone

fetal complications: preterm delivery, fetal growth restrictions, stillbirth, miscarriage

18

pregnancy complications in mother w/ antiphospholipid syndrome? tx w/?

increase risk of miscarriage
risk for developing preeclampsia
fetal growth restriction

tx: heparin/LMW heparin and low-dose aspirin

19

most common cause of asymptomatic bacteriuria/UTI in pregnant mom? tx?

E coli

may need suppressive abx tx with recurrent infx

20

pyelonephritis in mom can result in what? tx?

can result in adult RDS

Tx: IV hydration, abx, antipyretics, tocolytics if needed, will need suppression for remainder of pregnancy

21

tx of n/v of pregnancy?

symptomatic-vit B6, doxylamine, promethazine

50-80% of women complain of n/v during first 8-12 weeks

22

when does hyperemesis gravidarum frequently occur? outcomes? tx?

frequently in 1st pregnancies, multiple pregnancies, trophoblastic disease

outcomes are good

tx is symptomatic

23

tx of GERD? tx of peptic ulcer?

GERD: symptomatic --> small meals, avoid lying down after eating, elevate head when sleeping, antacids, H2 blockers/PPIs

Ulcers: pregnancy may improve condition, tx is avoid caffeine, alcohol, tobacco, spicy foods; antacids, H2 blockers/PPIs, abx tx to tx H pyolori

24

tx of acute fatty liver of pregnancy?

-termination of pregnancy
-supportive care --> IV fluids w/10% glucose, FFP and cryoprecipitate
-maternal mortality 7-18%
-fetal mortality 9-23%
-if survive, usually full recovery

25

most common cause of anemia in pregnancy? when to screen? how to tx?

Fe-deficiency

screened at initial prenatal visit and again at 26-28 wks

Fe supplementation

26

symptoms and tx of superficial thrombophlebitis in pregnant woman?

symptoms: swelling, tenderness

tx: bed rest, pain meds, local heat, no need for anticoag, wear support hose

27

symptoms of DVT? Dx? Tx?

symptoms: more common in left leg than right, pain in calf with dorsiflexion (Homanns sign), may also have dull ache, tingling, or pain with walking

Dx: clinically difficult (50% are asymptomatic), compression US with doppler flow, MRI may be used if suspect pelvic thrombosis

tx: anticoag tx should be initiated when clinically dx
-use LMW or UFH --> follow aPTT values with Heparin and Factor Xa values w/LMW to assure therapeutic values
-Coumadin used for 6 wks postpartum but NOT during pregnancy d/t risk of fetal hemorrhage or teratogenesis (Follow INR)

28

symptoms of PE? signs?

symptoms: pleuritic chest pain, short of air, air hunger, palpitations, hempotysis
