|
|
environmental risk factors
|
|
|
indications for antepartum testing
|
diabetes, chronic HTN, preeclampsia, multiple gestation, oligohydramnios, preterm premature rupture of membranes, postdate and decreased fetal movement |
|
fetal movements in third trimester |
fetus makes about 30 gross body movements every hour, mother is able to recognize 70 to 80% |
|
When does fetal movement warrant further evaluation?
|
less than 3 movements within one hour, need to evaluate by a nonstress test or a contraction stress test or a modified biophysical profile |
|
What is the most valuable diagnostic tool used in obstetrics?
|
diagnostic ultrasonohraphy provides fetal activity, gestational age, normal vs. abnormal fetal growth curves, fetal and placental anatomy, fetal well being and visual assistance
|
|
limited exam indications
|
identifying fetal presentation during labor ir estimating AFV |
|
specialized or targeted exam indications |
performed if a woman is suspected of carrying an anatomically or physiologically abnormal fetus |
|
what should the woman do to provide a good image during an abdominal ultrasound? |
should have a full bladder to displace the uterus upward |
|
indications for ultrasound in the first trimester |
number of fetuses, size, location of gestational sacs, presence of fetal cardiac and body movements, presence of uterine abnormalities, adrenal masses or ovarian cysts |
|
indications for ultrasound in second and third trimesters |
fetal viability, number, position, gestational age, growth pattern, abnormalities, amonotic volume, placental location, presence of uterine fibroids, adrenal masses and cervical length |
|
how do you confirm fetal death?
|
lack of heart motion along with the presence of fetal scalp edema and maceration and overlap of the cranial bones
|
|
when can fetal heart rate be detected by transvaginal ultrasound? |
around 6 weeks of gestation |
|
