vs fetus

A

mom: Increased risk for hypovolemia, anemia, infection, preterm labor, and preterm birth

Management?

A

Missed period
Adnexal fullness

Q

What are the maternal and fetal outcomes for placenta previa?

A

-maternal morbidity and mortality
complications
-fetal risks , malpresentation and congenital abnormalities
-preterm birth

17
Q

How do you diagnose placenta previa?

Management ?

A

transabdominal ultrasound exam

observation and rest
cesarean birth
hospital/home care

18
Q

What is placental abruption?

A

premature separation of placenta

19
Q

What are the risks for placental abruption?

A 
MVA
Trauma
Battering
Smoking
Thrombophillas
Twins
Previous abruptio
Cocaine
20
Q

Clinical manifestations of placental abruption?

A

Boardlike abdomen
contractions
vaginal bleed with uterine pain [ usually darker and less than previa]

21
Q

What is Velamentous cord?

A

cord vessels branch at membranes and course onto placenta. its exposed and not protected by whartons jelly.

rupture of membranes or traction on cord may tear one or more fetal vessels. so then fetus may rapidly bleed to death

22
Q

What is battledore cord?

A

Cord is inserted at or near the placental margin. it increases risk of hemorrhage.

23
Q

What does normal clotting do?

A

stops flow of blood from injured vessels through formation of insoluble fibrin, which acts as a hemostatic platelet plug.

24
Q

What is the coagulation process in normal clotting?

A

coagulation processes involves interaction of coagulation factors, in which each factor sequentially activates factor next in line

THE CASCADE EFFECT SEQUENCE

25
Q

What is the fibrinolytic system process?

A
  • fibrin splits into fibrinolytic degradation products

- circulation restored

26
Q

What is DIC?

A

Disseminated intravascular coagulation
- pathological form of diffuse clotting causing widespread external and internal bleeding.

google :Disseminated intravascular coagulation (ko-ag-u-LA-shun), or DIC, is a condition in which blood clots form throughout the body’s small blood vessels. These blood clots can reduce or block blood flow through the blood vessels, which can damage the body’s organs.

27
Q

What is von willebrand’s disease?

A

type of hemophilia that can affect women.

28
Q

The effect of trauma on pregnancy is influenced by —?

A
  • length of gestation
  • type and severity of the trauma
  • degree of disruption of uterine and fetal physiologic features
29
Q

Maternal physiologic characteristics in trauma?

A
  • uterus and bladder positioning
  • elevated levels of progesterone
  • decreased tolerance for hypoxia and apnea
  • cardiac output
  • circulating blood volume
30
Q

Fetal physiological characteristics in trauma?

A
  • careful monitoring of fetal status assists greatly in maternal assessment
  • fetal monitor tracing works as oximeter of internal maternal well being.
31
Q

Nursing care management for fetus following a trauma?

A 
immediate stablization
primary survey
secondary survey
electronic fetal monitoring
perimortem caesarean delivery
discharge planning
32
Q

Abruption placentae VS Placenta previa?

A

placenta previa
clinical manifestations: bright red vaginal bleeding
risks: previos c/s, AMA, hx of D&C or suction curettage, smoking

abruption placentae
clinical manifestations: birdlike abdomen, contractions, vaginal bleed with uterine pain. blood is darker and less than previa.
RISKS: mva, trauma, battering, smoking, thrombophilia, twins, previous abruption, cocaine

33
Q

Do physiological adaptations of pregnancy mask warning signs and changes in vital signs during early shock states?

A

YES

34
Q

What does fetal survival depend on?

A

maternal survival. after trauma, first priority is mom before consideration of baby.

35
Q

What are some major complications to minor traumas in pregnancy?

A

abruption placentae, fetomaternal hemorrhage , preterm labor and birth, fetal death.
