MTB Obs Flashcards
Preeclampsia is characterized by…
HTN, proteinuria and oedema
Rh sensitized mother, what to do?
Serial amniocentesis to measure the fetal bilirubin level.
High bilirubin requires intrauterine transfusion
Preterm eclampsia, what to do?
Betamethasone
Magnesium sulphate
HELLP Syndrome, what is it and what to do?
Complication of preeclampsia.
Hemolysis, elevated liver enzymes, low platelet.
Treatment is the same as eclampsia; magnesium sulphate and hydralazine, (betamethasone)
Gestational diabetes treatment
Diet, exercise, then insulin
Never say lose weight
IUGR prevention
Quit smoking and immunization
Fetal heart rate
N. 110-160
Brady. 160
CTG: deceleration types and causes
Early - head compression
Variable - umbilical cord compression
Late - fetal hypoxia
Benign contraction without cervix dilation
Braxton-Hicks contraction
Protracted cervical dilation etiology
3 Ps
Power, passenger, passage
Cesarian or oxytocin
Shoulder dystocia treatment
McRoberts maneuver
Rubin maneuver
Woods maneuver
Nagele rule:
LMP- 3 months + 7 days = estimated day of delivery
Signs of Pregnancy
Goodell sign,
Telangiectasias/ palmar erythema
softening of the cervix
Small blood vessels/reddening of the palms
Quickening is
16 to 20 weeks:
the first time the mother feels fetal movement.
Beta-HCG >1500 or
5 weeks =
gestational sac on ultrasound
A triple screen includes
maternal serum alpha fetoprotein (MSAFP), beta- HCG, and estriol.
Chorionic Villus Sampling
• Done at 10 to 13 weeks in advanced maternal age or known genetic dis- ease in parent
Amniocentesis
• Done after 11 to 14 weeks for advanced maternal age or known genetic dis- ease in parent
Preterm fetuses without chorioamnionitis should be treated with
betametha- sone (to mature the lungs), tocolytics (to decrease contractions), ampicillin, and 1 dose of azithromycin (to decrease risk of developing chorioamnionitis while waiting for steroids to begin working).
Rh incompatibility occurs when
the mother is Rh negative and the baby is Rh positive. This is generally not a problem in the first pregnancy, as the mother has not developed antibodies to the “foreign” Rh positive blood yet.
Pregnancy HTN
Treat the patient with methyldopa, labetalol, or nifedipine.
