Q

What is Rh sensitization?

A

Occurs when the mother is Rh negative and the father is Rh positive, the fetus could inherit the factor from the father. The fetal blood can enter the woman’s circulation and produce a maternal antibody to the factor. In subsequent pregnancies the antibodies will attack the fetal RBCs

Q

How does epilepsy effect pregnancy?

A

Most have a normal pregnancy
Medication may be effected by altered hemodynamics
Onset of labour can trigger seizures which can cause fetal distress
Increased risk of vaginal bleeding both during and after pregnancy

20
Q

What are some causes of vaginal bleeding

A

Abortion
Ectopic pregnancy
Abruption placentae
Placenta previa
Uterine rupture
Postpartum hemorrhage

21
Q

What is Abortion

A

Expulsion of the fetus before the 20th week
Most occur during the first trimester before the placenta is fully mature

22
Q

What is a spontaneous abortion (miscarriage)

A

-occurs naturally
-affects about 1 out of every 5 pregnancies

23
Q

What causes a spontaneous abortion

A

-acute or chronic illness in pregnant woman
-Maternal exposure to toxic substances
Abnormalities in the fetus
Abnormal attachment of the placenta

24
Q

What is an induced abortion

A

Brought about intentionally
Complications such as vaginal bleeding or sepsis from having parts of the fetus in utero
Can be self induced

25
Q

What are the stages of abortion

A

threatened
Inevitable
Incomplete
Missed
Septic

26
Q

What is threatened abortion

A

Attempting to take place
vaginal bleeding during first half of pregnancy
Can progress or subside
Continue with normal activity

27
Q

What is an inevitable abortion

A

Spontaneous abortion that cannot be reversed
Severe abdominal pain caused by strong uterine contractions
Vaginal bleeding and cervical dilation

28
Q

What is an incomplete abortion

A

Some of the products of the conception remain in the uterus
Cervix dilated to expel the fetus
Be alert for signs of shock
If products of conception are protruding from the vagina, consult OLMC
Fundal massage

29
Q

What is a missed abortion

A

Fetus dies during the first 20 weeks but remains in utero
Transport and emotional support
Cessation of vaginal bleeding followed by a gradual dismissing of the signs or pregnancy
Brownish vaginal discharge
Generally precedes a spontaneous abortion

30
Q

What is a septic abortion

A

Uterus become infected

31
Q

What are some causes of vaginal bleeding in the third trimester

A

Abruptio placentae
Placenta previa
Uterine rupture

32
Q

What is the greatest danger in third trimester bleeding

A

Hemorrhage
becomes more acute as the woman approaches term
Large volume of blood presents within the pregnant woman’s body
Compensatory mechanisms functioning as a result of pregnancy

33
Q

What is abruptio placentae

A

Premature separation of a normally implanted placenta
Most common during the last trimester of pregnancy
Maternal hypertension is the most common cause

34
Q

What are the risk factors for abruptio placentae

A

-Trauma
-Maternal hypertension
-Preeclampsia
-Multiparity
-Previous abruption

35
Q

Symptoms of abruptio plancentae

A

Sudden onset of severe abdominal pain
Signs of shock
Severe hemorrhaging
Possible contraction / premature labour

36
Q

What is placenta previa

A

Placenta is implanted low in the uterus and partially or fully obscures the cervical canal
Leading cause or vaginal bleeding in the second and third trimesters of pregnancy
C/C is painless vaginal bleeding

37
Q

What causes a uterine rupture

A

Prolonged labour
trauma
Women who have had previous C-sections

38
Q

Symptoms of a uterine rupture

A

Signs of shock
Bleeding may be hidden
Described as tearing
Rare but accounts for 5-15% of maternal deaths

39
Q

What is hyperemesis gravidarum

A

Morning sickness
Condition or persistent nausea and vomiting during pregnancy
Prolonged vomiting leads to dehydration and malnutrition
Exact cause is unknown
Vomiting is projectile and consists of bile and possibly blood

40
Q

Prehospital treatment for morning sickness

A

100% O2
Start and IV
Gravol
BGL
Orthostatic vital signs
Transport

41
Q

What is a molar pregnancy

A

Genetic error during fertilization resulting in abnormal placenta
Can be complete or partial

42
Q

Symptoms of a molar pregnancy

A

Preeclampsia
Vaginal bleeding
Severe N/V
Pelvic pain / pressure

43
Q

Treatment for molar pregnancy

A

Prenatal screenings tend to find most instances of molar pregnancies
Pregnancy terminates itself or a DNC is preformed

44
Q

What is a partial mole?

A

Two sperm on one egg join to form and embryo with 69 chromosomes

45
Q

What is a complete mole

A

One sperm enters an egg which has lost its chromosomes. The sperm duplicates its own chromosomes therefore the pregnancy has only paternal chromosomes

46
Q

What is an ectopic pregnancy?

A

Severe disorder with potentially life-threatening consequences
Fertilized ovum becomes implanted somewhere other than the uterus
Normal signs of pregnancy are present
Severe pain with hypovolemic shock
Requires rapid transport for surgery
Manage for hemorrhagic shock

47
Q

What are the causes of maternal trauma

A

Vehicular crashes
Falls
Penetrating objects
