25
Usually preceded by premonitory s/s, including persistent HA, blurred vision, severe epigastric or RUQ abdominal pain, and altered mental status
Eclampsia
26
What follows an eclampsia seizure?
Hypotension, muscular twitching, disorientation, amnesia
27
What do you monitor with eclamptic pts?
Urine output, lung sounds, DTRs, may have mag sulfate toxicity. You expect BP to be low, but really watch the respirations
28
A lab diagnosis for a variant of severe preeclampsia that involves hepatic dysfunction
HELLP Syndrome
29
HELLP Syndrome is characterized by what?
- Hemolysis (H) - Elevated liver enzymes (EL) - Low platelets
30
HELLP Syndrome usually develops when?
Antepartum period, progresses rapidly
31
Mag sulfate is continued after birth for how long?
12-24 hours
32
Preeclamptic women should be hospitalized where?
Tertiary care facility that is able to provide both maternal and neonatal intensive care
33
What meds are ordered to enhance fetal lung maturation?
Corticosteroids | Betamethasone, Celestone
34
When is immediate birth indicated?
If eclampsia, pulmonary edema, placental abruption, DIC, or renal dysfunction develops
35
What meds are given for preeclampsia?
- Mag sulfate - Hydralazine - Labetalol - Procardia - Celestone
36
Excessive N/V that doesn't subside throughout pregnancy. Causes weight loss, electrolyte imbalance, nutritional deficiency, and ketonuria
Hyperemesis Gravidarum
37
Complications of hyperemesis gravidarum
- IUGR - Low birth weight - Prematurity - 5 min agars less than 7
38
Maternal risks from a hemorrhagic disorder
Hypovolemia, anemia, infection, preterm labor
39
Fetal risks from a hemorrhagic disorder
Blood loss, anemia, hypoxemia, hypoxia, anoxia, and preterm birth
40
What has the highest incidence of maternal mortality?
Ruptured ectopic pregnancy and abruptio placentae
41
Types of early pregnancy bleeding
Miscarriage, reduced cervical competence/incompetent cervix (premature dilation of cervix), ectopic pregnancy, hydatidiform mole (molar pregnancy)
42
A pregnancy that ends without medical surgical methods before 20 weeks or gestation or fetal weight of less than 500 grams
Miscarriage
43
Threatened miscarriage (A)
You don't really know if it's gonna happen or not
44
Inevitable miscarriage (B)
You know for sure they're going to deliver
45
Incomplete miscarriage (C)
Not all the products of conception are delivered. Sometimes the placental is retained. D&C cleans out the uterus
46
Complete miscarriage (D)
Everything comes out
47
Missed miscarriage (E)
Fetus has died in utero but has not delivered yet
48
Septic miscarriage
There's an infection in the uterus and the baby is going to miscarry
49
Recurrent (habitual) miscarriage
A woman just keeps miscarrying
50
What meds do you do for miscarriage?
Maybe IV fluids or pain meds, really you just watch and wait
51
Cytotec
Drug that causes uterine contractions to help expel the products of conception
52
RhoGAM with miscarriages
They go ahead and give the mom a dose cause they won't know what the baby was
53
Passive and painless dilation of the cervix during the second trimester
Reduced cervical competence/Incompetent cervix. May cause recurrent miscarriages
54
Causes of Incompetent Cervix
- Previous cervical trauma - Lacerations during childbirth - Excessive cervical dilation for curettage or biopsy - Exposure to DES (diethylstilbestrol)
55
Most common way to treat incompetent cervix
Cerclage
56
A suture is placed around the cervix beneath the mucosa to constrict the internal cervix
Cerclage
57
How is a cerclage placed?
Prophylactically (11-15 weeks) or as a rescue procedure once the cervix has been found to be effaced or dilated
58
Risks with cerclages
- Premature ROM - PTL - Chorioamnionitis
59
Follow up care with cerclages
- Bedrest - Avoid sex - Stress importance of initial activity restriction and close observation
60
Patient education with cerclages
Signs of PTL: - Infection - Contraction - ROM - Severe perineal pressure - Urge to push
61
The frequency of ectopic pregnancies is consistent across what?
Maternal age ranges and ethnic origins
62
Causes of ectopic pregnancies
- Previous ectopic pregnancy - History of STDs - Fallopian tube scars form PID - Endometriosis - Previous pelivc surgery - Infertility treatment - Uterine fibroids - Previous intrauterine contraception
63
Clinical manifestations before rupture of ectopic pregnancy
- Dull LQ abdominal pain on one side - Delayed menses - Spotting occurring 6-8 weeks after last normal menstrual period - Mild to moderate dark red or brown intermittent vaginal bleeding
64
Clinical manifestations after rupture of ectopic pregnancy
- Referred shouolder pain: diaphragmatic irritation caused by blood in the peritoneal cavity - Generalized, one sided or deep LQ acute abdominal pain - Faintness, dizziness r/t amount of bleeding in abdominal cavity - Cullen sign
65
Ecchymotic blueness around umbilicus
Cullen sign
66
Medical treatment for ectopic pregnancy if the pt desires a future pregnancy
Methotrexate IM | 3.5 cm or less, no fetal cardiac activity, enraptured, condition stable
67
Surgical removal of fallopian tube
Salpingectomy
68
Incision made for removal of products of conception (for ectopic pregnancies)
Salpingostomy
69
Benign proliferative growth of the placental trophoblast in which the chorionic villi develop into edematous, cystic, avascular transparent vesicles that hand in a grapeike cluster
Hydatidiform Mole (molar pregnancy)
70
A group of pregnancy related trophoblastic proliferative disorders without a viable fetus that are caused by abnormal fertilization
Gestational trophoblastic dz
71
GTD includes what?
Molar pregnancies, invasive mole and choriocarcinoma
72
Cause of molar pregnancies
Unknown but may be r/t an ovular defect or a nutritional deficiency
73
Who is at an increased risk for molar pregnancies?
Women who have had a previous molar pregnancy, early teens or older than 40 years of age
74
Types of molar pregnancies
Complete and partial
75
Clinical manifestations of molar pregnancies
- Dark brown (looks like prune juice) or bright red vaginal bleeding, either scant or profuse - Excessive N/V - Abdominal cramps - Signs of preeclampsia before 24 weeks of gestation - Excessively enlarged uterus
76
What labs do you frequently check with molar pregnancies?
Serum hCG levels
77
A rising titer of serum hCG levels and enlarged uterus may indicate what?
