prenatal ultrasound
To evaluate baby's growth and development. Evaluates for possible problems and
diagnose. Done during first tri to confirm pregnancy. Done during second tri to show
anatomic details.
amniocentesis
needle puncture of the amniotic sac to withdraw amniotic fluid for analysis. Can
induce miscarriage in early pregnancy.
RhoGAM
Used to prevent an immune response to Rh positive blood in people with an Rh
negative blood type. Mother negative baby positive.
Maternal Gestational Hypertension
Hypertension during pregnancy that is 30mmg above normal diastolic pressure and
15mmg above normal systolic pressure. Mother did not have hypertension before
pregnancy.
Group B strep
a common bacterium often carried in the intestines or lower genital tract. The
bacterium is usually harmless in healthy adults. In newborns, however, it can cause a
serious illness known as group B strep disease. Can also cause dangerous infections in
adults with certain chronic medical conditions, such as diabetes or liver disease
"cold sores"; clear vesicles with red base that evolve into pustules, usually at lip-skin
junction. The main concern with maternal herpes Simplex viral infection during
pregnancy is the risk of neonatal infection as this can lead to severe neurological
impairment and to death it is most likely to occur if the mother develops HSV for the
first time during the final trimester. No breastfeeding with open lesions.
Toxoplasmosis
a disease that results from infection with the toxoplasma Gandhi parasite, one of the
worlds most common parasites. Infection usually occurs by eating undercooked
contaminated meat exposure from infected cat feces or mother to child transmission
during pregnancy
Gestational diabetes and exercise
Mothers with gestational diabetes will be put on a special diet and exercise plan
Effects of Zika, TORCH on developing pregnancy
Transmitted by mosquitos, was prominent in Latin America and other southern islands
south of florida. Causes microcephaly(small brain volume), developmental delay. No
treatment, just prevention
uterine contractions
Prior to delivery, hormones trigger waves of smooth muscle contraction in the
myometrium that slowly increase in strength and frequency. At the same time, the
smooth muscle tissue of the cervix begins to efface, or thin, and dilate from less than a
centimeter in diameter to around ten centimeters at full dilation. Once the cervix is fully
dilated, the uterine contractions drastically increase in intensity and duration until the
fetus is pushed out of the uterus, through the vagina, and out of the mother's body
True Versus False Labor
• False labor is a condition occurring during the latter weeks of some pregnancies in
which irregular uterine contractions are felt, but the cervix is not affected.
• In contrast, true labor is characterized by contractions occurring at regular intervals that
increase in frequency, duration, and intensity. True labor contractions bring about progressive
cervical dilation and effacement.
