BP elevation (=/>140 SBP or =/> 90 DBP) after 20 weeks gestation NOT accompanied by proteinuria
BP elevation after 20 weeks gestation with significant proteinuria
PE effects on fetus
IUGR, oligohydramnios, hypoxia and late decels during labor rt decreased placental perfusion
>0.3 g in 24 hr specimen; dipstick =/> +1
patho of PE
vasospasms cause vasoconstriction which decreases blood flow and increases BP. circulation to the liver, kidneys, brain and placenta decrease
risk factors for PE
primipara, >35 yo, family history of PE, obesity, DM, chronic renal disease, anemia, pre-existing HTN
amniotic fluid embolism
An embolism in which amniotic fluid with its particulate matter is drawn into the pregnant woman's circulation, lodging in her lungs
A disorder in which amniotic fluid with its particulate matter enters the pregnant woman's circulation, lodging in her lungs. Previously called amniotic fluid embolism.
Condition in which the fetal head is too large to fit through the maternal pelvis at birth. Also called fetopelvic disproportion.
Encircling of the cervix with suture to prevent recurrent spontaneous abortion caused by early cervical dilation
Inflammation of the amniotic sac (fetal membranes); usually caused by bacterial or viral infection. Also called amnionitis.
Difficult or prolonged labor; often associated with abnormal uterine activity and cephalopelvic disproportion.
Excessive volume of amniotic fluid (more than 2000 mL at term). Also called polyhydramnios.
hypertonic labor dysfunction
Ineffective labor characterized by erratic and poorly coordinated contractions. Uterine resting tone is higher than normal.
hypotonic labor dysfunction
Ineffective labor characterized by weak, infrequent, and brief but coordinated uterine contractions. Uterine resting tone is normal.
Unusually large fetal size; infant birth weight more than 4000 g (8.8 lb).
A pregnancy in which the woman is carrying two or more fetuses. Also called multiple gestation.
Abnormally small volume of amniotic fluid (less than 500 mL at term).
A birth that occurs without a trained attendant present.
An intense, unusually short labor (less than 3 hours).
Onset of labor after 20 weeks and before the beginning of the 38th week of gestation.
Displacement of the umbilical cord in front of or beside the fetal presenting part. An occult prolapse is one that is suspected on the basis of fetal heart rate patterns; the umbilical cord cannot be palpated or seen.
Delayed or difficult birth of the fetal shoulders after the head is born.
A drug that inhibits uterine contractions.
Turning of the uterus inside out after birth of the fetus.
uterine resting tone
Degree of uterine muscle tension when the woman is not in labor or during the interval between labor contractions.
A tear in the wall of the uterus.
pelvic shape with a wide pubic arch, round, cylindrical shape, and good prognosis for vaginal birth
pelvic shape with narrow pubic arch, long narrow oval shape, and decently favorable prognosis for vaginal birth, but more prone to OP position
pelvic shape with a narrow pubic arch, narrow diameters, heart or triangle shape, and poor prognosis for vaginal birth
pelvic shape with wide pubic arch, flat, wide, short oval shape, and poor prognosis for vaginal delivery
first sign of intrauterine infection
fetal tachycardia: >160 BPM for term fetus, or a rising baseline FHR
premature rupture of the membranes (PROM)
rupture of the amniotic sac before onset of true labor
rupture of membranes earlier than the end of the 37th week of gestation
microscopic eval of vaginal fluid to determine if it is amniotic fluid
beta agonist: relaxes uterine smooth muscle; used to reduce or stop hypertonic contractions; may cause maternal tachycardia or arrhythmias
prostaglandin inhibitor: relaxes uterine smooth muscle; inhibits preterm labor; may cause premature closure of ductus arteriosus
CCB: suppression of premature labor;
