Prenatal Counseling and Care -
prenatal care is divided into trimesters;
- first trimester - up to 14 weeks of gestation
- second trimester - 14 to 28 weeks of gestation
- third trimester - 28 weeks to delivery
Prenatal care is important in screening
for various complications of pregnancy. This includes routine office
visits with physical exams and routine lab tests: Prenatal care is important in screening for various

Dealing
With The Changes - During pregnancy, the woman
undergoes many physiological changes, which are entirely normal,
including cardiovascular, renal, hematologic, metabolic or respiratory
changes that become very important in the event of complications.

Centering
Pregnancy Program -
The
Centering Pregnancy® Program alters
routine prenatal care by bringing women out of exam rooms and into groups
for their care. Women have their initial intake into their obstetric care
in the usual manner with history and physical examination occurring within
the office/clinic space. Then they are invited to join with 8-12 other
women/couples/teens with similar due dates in meeting together regularly
during their pregnancy. The groups form between 12 and 16 weeks of
pregnancy and continue through the early postpartum period meeting every
month for the first four months and then bi-weekly. To get more
information or to be able to print a brochure on the
Centering Pregnancy Program
The
Centering Pregnancy® Program
is a model of empowerment: empowering to women to take control of their
bodies, their pregnancies, and their families, and empowerment to us as
health care providers to share our care-giving with our guests.
First trimester
- complete blood count (CBC)
- blood type (blood transfusion
may be needed in an emergency)
- general antibody screen
(indirect Coombs test) for HDN
- Rh D negative antenatal
patients should receive RhoGam at 28 weeks to prevent Rh
disease.
- Rapid plasma reagent (RPR)
which screens for syphilis
- Rubella antibody screen
- Hepatitis B surface antigen
- Gonorrhea and Chlamydia
culture
- PPD for tuberculosis
- Pap smear
- Urinalysis and culture
- HIV screen
- Group B Streptococcus screen
-- will receive IV penicillin if positive (if mother is
allergic, alternate therapies include IV clindamycin or IV
vancomycin)
Second trimester
- MSAFP/triple screen (maternal
serum alpha-fetoprotein) - elevation correlated with neural tube
defects and decrease correlated with Down's syndrome
ultrasound
- amniocentesis in older
patients
Third trimester
- hematocrit (if low, mother
will receive iron supplementation)
- glucose loading test (GLT) -
screens for gestational diabetes; if > 140 mg/dL, a glucose
tolerance test (GTT) is administered; if fasting glucose > 105
mg/dL, gestational diabetes is suggestive.
Prenatal screening is
looking for signs like the following:
- Bluish discoloration of
vagina and cervix (Chadwick's sign)
- Softening and cyanosis
of cervix after 4 weeks (Goodell's sign)
- Softening of uterus
after 6 weeks (Ladin's sign)
- Breast swelling and
tenderness
- Linea nigra from
umbilicus to pubis
- Telangiectasias
- Palmar erythema
- Amenorrhea
- Nausea and vomiting
- Breast pain
- Fetal movement
- Sciatica (Pain caused
by compression of the sciatic nerve)

the Art Diagnostic Equipment - There is need to go elsewhere for
additional testing in most cases
Antenatal care
In obstetric practice, the obstetrician will see a pregnant woman on a
regular basis to check the progress of her pregnancy. The exact schedule
varies depending on resources and risk factors, such as diabetes. The main
rationale for these visits is surveillance for diseases of pregnancy which
are detectable. Some examples are: pre-eclampsia. The blood-pressure and
urine of a pregnant woman is checked at every opportunity to check for
this. placenta praevia. On ultrasound, the placenta is visible obstructing
the birth canal
abnormal presentation (late pregnancy only). The fetus may be feet-first
or buttocks-first(breech), side-on (transverse), or at an angle (oblique
presentation) IUGR (Intrauterine Growth Restriction), this is a general
designation, where the fetus is too small for its gestational age. Causes
can be intrinsic (in the fetus) or extrinsic (usually placental problems).
IUGR refers to fetal growth that is less than 10% of what is expected at
that gestational age.
Antenatal record
On the first visit to her obstetrician or midwife, the pregnant woman is
asked to carry out the antenatal record, which constitutes a medical
history and physical examination.
On subsequent visits, the gestational age (GA) is rechecked with each
visit. Symphysis-fundal height (SFH; in cm) should equal gestational age
after 20 weeks of gestation, and the fetal growth should be plotted on a
curve during the antenatal visits. The fetus is palpated by the midwife or
obstetrician using Leopold maneuver to determine the position of the baby.
Blood pressure should also be monitored, and may be up to 140/90 in normal
pregnancies. High blood pressure indicates hypertension and possibly pre-eclampsia,
if severe swelling (edema) and spilled protein in the urine are also
present.
Fetal screening is also used to help assess the viability of the fetus, as
well as congenital problems. Genetic counseling is often offered for
families who may be at an increased risk to have a child with a genetic
condition. Amniocentesis at around the 20th week is sometimes done for
women 35 or older to check for Down's Syndrome and other chromosome
abnormalities in the fetus. Even earlier than amniocentesis is performed,
the mother may undergo the triple test, nuchal screening, nasal bone,
alpha-fetoprotein screening and Chorionic villus sampling, also to check
for disorders such as Down Syndrome. Amniocentesis is a prenatal genetic
screening of the fetus, which involves inserting a needle through the
mother's abdominal wall and uterine wall, to extract fetal DNA from the
amniotic fluid. There is a risk of miscarriage and fetal injury with
amniocentesis since it involves penetrating the uterus with the baby still
in utero.
Trimesters
First trimester: elevated β-hCG (up to 100,000 mIU/mL by 10 weeks GA) can
cause morning sickness, fatigue, mood swings and food cravings. The
symptoms can last through 12 to 16 weeks of gestation.
Second trimester: The abdomen shows an obvious swelling arising from the
pelvis, starting the "obvious phase" of pregnancy.
Hyperpigmentation,
including linea nigra, may appear.
Third trimester: The mother may experience backaches due to increased
strain. Typically, the curvature of the spine is changed as pregnancy
evolves in order to counteract the change in weight distribution. The
mother may also suffer mild urinary incontinence due to pressure on the
bladder by the pregnant uterus, as well as heartburn (due to compression
of the stomach).
