Transcript and Presenter's Notes

Title: Placenta


1
Placenta
  • A Circular vascular structure that collects
    wastes.

2
Placenta Previa
  • When the placenta is underneath the baby coming
    out first.

3
Abruptio Placentae
  • When the placenta separates from the uterus
    prematurely.

4
Amniotic Sac
  • The bag of membranes containing the fetus and the
    amniotic fluid. Its functions is to protect the
    baby.

5
Breech
  • Birth presentation in which the baby is not
    head first. It could either be buttocks or feet
    first.

6
Normal delivery
  • The baby should be exiting the vaginal canal face
    first facing the mothers back.

7
Amniocentesis
  • A needle is inserted into the abdomen to detect
    birth defects in mothers 35 years and older.

8
Ultrasound
  • An instrument used to visually evaluate the baby
    and detect any
  • abnormalities.

Dilated Cervix
  • The baby can be delivered when the cervix is
    dilated to 10 cm. Effacement is the lining of the
    cervix.

12
Epidural
  • Regional anesthesia delivered near the spinal
    cord between the vertebrae.

13
Forceps
  • A tool used to help extract the baby late in labor

14
Vacuum extractor
15
Physical symptoms of a pregnant woman
16
Linea Nigra
  • a dark line appearing on the abdomen.

17
Mask of pregnancy
  • Spots and patches of a yellowish-brown color on
    the face due to the hormones of pregnancy

18
Extremely swollen ankles
  • A pregnant woman will have two times the amount
    of blood in her body and therefore swelling can
    be the end result.

19
  • Extreme pressure on the internal organs which may
    cause
  • Difficulty breathing
  • Indigestion or decrease in appetite
  • Constipation
  • Gas
  • Pain and discomfort

20
Complications of Pregnancy and Birth
21
Etopic Pregnancy
  • The pregnancy tissue or embryo becomes implanted
    in the fallopian tubes or somewhere else in the
    abdomen besides the uterus. The embryo may die
    and frequently must be removed by surgery.

22
Etopic Pregnancy

23
Toxemia
  • The pregnant woman has high blood pressure,
    swelling, and protein in the urine. Untreated
    toxemia can result in convulsions, coma and the
    death of both mother and infant. It is most
    common among teenagers, older women, and women
    who already have health problems.

24
Rh Incompatibility
  • A womans blood produces an antibody that attacks
    a substance in the infants blood cells. This
    may occur if the woman is Rh negative and the
    infant is Rh positive. The problem can be
    avoided by injections that prevent a womans
    blood from making RH antibody.

25
Premature Birth

A baby is born before it is fully developed. A
baby is considered to be premature if it is born
before the 37th week of pregnancy. Premature
babies are placed in a newborn intensive-care
unit, where the baby is protected while it
continues to develop.
26
Cesarean Section
  • If delivery through the birth canal is considered
    to be risky for any reason, an operation called a
    cesarean section is performed. An incision is
    made through the abdomen and uterus, and the baby
    is taken from the mothers body

27
Multiple Births
  • Two or more infants are born together. Two
    infants are called twins, three are called
    triplets, and four are called quadruplets. The
    birth of five infants quintuplets is
    extremely rare

28
Stillbirth
  • An infant that is born dead 22 weeks or more
    after conception.

29
Umbilical Cord
  • the connecting cord from the developing fetus to
    the placenta
  • The umbilical vein supplies the fetus with
    oxygenated, nutrient-rich blood from the placena

30
Miscarriage (spontaneous abortion)
  • The pregnancy tissue or embryo is expelled from
    the uterus before it is sufficiently developed.
    Miscarriage may be caused by a genetic defect,
    illness in the mother, drugs the mother has
    taken, or other factors. Miscarriage usually
    occur during the first three months of pregnancy.
