When will it end! Flashcards
Postterm pregnancies should be followed with antepartum fetal surveillance because ?
perinatal morbidity and mortality increases beginning at 41 weeks of gestation
Postterm pregnancies are associated with?
macrosomia, oligohydramnios, meconium aspiration, uteroplacental insufficiency and dysmaturity.
In a patient with irregular menses, it is important to obtain an ultrasound prior to________ to accurately date the pregnancy.
20 weeks
Induction of labor in a patient with ___________ increases the risk of Cesarean section significantly
an unfavorable cervix- closed, long, non-effaced
Ablative therapy is an effective treatment for women with
high-grade or persistent low-grade cervical intraepithelial neoplasia (CIN)
no suspicion of glandular or invasive squamous disease
In growth-restricted pregnancies, oligohydramnios is frequently found because?
This finding is presumably due to reduced fetal blood volume, renal blood flow and urinary output
Chronic hypoxia is responsible for diverting blood flow from the kidney to organs that are more critical during fetal life.
An increase in the S/D ratio reflects increased vascular resistance, commonly found in
It is a common finding in IUGR fetuses.
As vascular resistance increases, the S/D ratio increases.
Tests indicated in monitoring fetuses with IUGR.
twice weekly NST with AFI and weekly umbilical artery Doppler studies- check for increased S/D ratio
before birth; during or relating to pregnancy; prenatal.
Antenatal
ultrasound measurement of the crown-rump length is preformed at?
obtained at six to twelve weeks
The crown-rump length can reliably date a pregnancy within five to seven days.
Fetal size w/ IUGR
- the fetal abdomen measures below normal and the head remains very close to normal
- weight is below normal
Symmetric fetal growth restriction indicates
all fetal measurements are below normal
indicates an intrinsic growth failure or an “early event” secondary to one or more organ system anomalies, fetal aneuploidy or chronic intrauterine infection.
a growth disorder that causes large body size, large organs, and other symptoms. It is a congenital condition
Beckwith-Wiedemann syndrome
When do you do a C section in macrosomia
baby over 5000 g
IUGR definition
less than 10th percentile
Prostaglandins are used for cervical ripening and are contraindicated in patients with ?
history of previous Cesarean section
