Medical Conditions in Pregnancy Flashcards
Gestational Diabetes- screening
- 50 gm 1 hr oral load glucose challenge (>130-140 abnormal)
- if abnormal- 3 hr 100 gm oral load gluc tolerance test
risk factors for GDM
- obesity
- prev hx of GDM
- strong FH of DM
- known glucose intolerance
GDM- maternal complications
- gestational HTN
- preeclampsia
- C-delivery
- developing diabetes later in life
GDM- fetal comlications
- macrosomia!! (> 4000 gms)
- hypoglycemia
- hyperbilirubinemia
- operative delivery
- shoulder dystocia!!!
- birth trauma
GDM pt- should deliver when?
b/w 39-40 wks
Pregestational diabetes- maternal complications
- worsening nephropathy and retinopathy
- preeclampsia
- DKA
Pregestational diabetes- fetal complications
- spontaneous abortions
- anatomic birth defects (birth defects assoc with inc HgBA1C in period of embryogenesis)
- fetal growth restriction
- prematurity
diabetes- management
diet, oral hypoglycemic medications (glyburide), insulin, exercise
-good glycemic control- fasting < 90, 2 hr postprandial < 120
Pregestational diabetes- maternal evaluation
- renal- 24 h urine collections
- cardiac- EKG
- eye exam in 1st trimester
- glycemic control
Pregestational diabetes- fetal evaluation
- US
- fetal echocardiogram
- congenital malformations- biochemical testing
- fetal growth US every 2-4 wks
postpartum management of diabetes
- insulin dep pts need 2/3 of pregnancy dose of insulin
- GDM freq dont need further tx
- GDM- need fasting blood gluc or 2 hr glucose tolerance 6-12 wks postpartum
maternal hyperthyroidism- tx
- PTU- 1st trimester
- methimazole- 2-3 trimester
maternal hyperthyroidism- fetal effects
-meds can cross placenta- fetal hypothyroidism and fetal goiter can develop
thyroid storm
- triggers- infection, labor, c-delivery
- hyperthermia, tachycardia, perspiration, high output cardiac failure, maternal mortality of 25%
thyroid storm- tx
- B-blockers- propranolol
- sodium iodide
- PTU
- dexamethasone
- replace fluid losses
- bring T down
Hypothyroidism- if untreated, inc risk of?
- sp abortion
- preeclampsia
- abruption
- low birth weight infants
- stillbirth
- lower intelligence levels
hypothyroidism- tx
-thyroid replacement
neonatal thyrotoxicosis
- due to transplacental transfer of thyroid stim ab’s
- transient
- mortality rate 16%
neonatal hypothyroidism
- causes developmental retardation
- caused by- thyroid dysgenesis, inborn errors of thyroid fxn, drug induced
Rheumatic HD
- mitral stenosis!!!
- high risk of HF, subacute bacterial endocarditis, thromboembolic dz
Cardiac arrhthmias
SVT!
-benign and assoc with overly strenuous exercise
postpartum cardiomyopathy
- develops within last wks of pregnancy or 6 months postpartum
- at risk- women with preeclampsia, HTN, poor nutrition
- mortality rate 10%
all pregnant cardiac pts should be?
comanaged with a cardiologist!!!
Immune Idiopathic Thrombocytopenia
- Igs attached to maternal platelets
- tx- when plts < 50,000- prednisone, IVIG, plt transfusion, splenectomy
SLE
- flares tx with prednisone
- fetal complications- preterm delivery, fetal growth restrictions, stillbirth, miscarriage
N/V of pregnancy
(50-80% of women complain of during first 8-12 wks)
Hyperemesis gravidarum
(1-2%)
- persistent N/V assoc with > 5% loss of prepregnancy wt, ketonuria, dehydration
- cause unknown
GERD
70% of pregnant women)
-small meals, avoid lying down after meals, elevate head when sleeping, antacids, H2 blockers/PPIs
Superficial thrombophlebitis
- palpable cord in calf- superficial!
- swelling, tenderness
- tx- bed rest, pain med, local heat wear support hose; dont need anticoagulants!!
DVT
-left leg- pain in calf with dorsiflexion (50% asx)
-US with doppler flow
-tx- anticoag tx- LMW (lovenox) or unfractionated heparin
-follow aPTT values (heparin), factor Xa values (lovenox)
have to avoid estrogen for contraception
PE- sx’s
- pleuritic chest pain, shortness of air, air hunger, palpitations, hemoptysis
- tachypnea, tachycardia, low grade fever, pleural friction
PE- evaluation, tx
- EKG, chest Xray, ABG, VQ, CT
- anticoag
- *require a thrombophilia work-up!!!
asthma
(3-9%)
-assoc with inc miscarriage, preeclampsia, intrauterine fetal demise, fetal growth restriction, preterm delivery
postpartum depression
(10-15 %)
-> first 2 wks postpartum
