Ante Natal Care (ANC)
Definitions
It is a planed examination and observation for the
woman from conception till the birth .
Or
Antenatal care refers to the care that is given to an
expected mother from time of conception is
confirmed until the beginning of labor
AIMS
There are three main purposes to antenatal care:
1. health promotion, health education - Identify high risk pregnant woman
2. preparation for labor and puerperium - Social and psychological support
3. parenthood and surveillance of risk.
- (providing appropriate
surveillance for all pregnancies in the hope of identifying the small
number that develop complications, with the aim of optimizing the
outcomes for both the mother and her baby).
Outcome of Antenatal Care
Outcome or impact :
To reduce maternal and neonatal mortality and
morbidity rates.
FACTORS AFFECTING PREGNANT
WOMEN:
- Demographic and Biological Factors
- Socioeconomic Factors
- Psycho-social Factors
- Health Services Factors
- Environmental Factors
Assessment and physical
examination
ANC
Care is often based on a traditional arrangement of antenatal visits.
The schedule varies, with the initial, or ‘booking’ visit, ideally
between 8 and 10 weeks, with subsequent visits 4-weekly until 30
weeks; 2-weekly until 36 weeks and then weekly thereafter.
The booking visit
- The purpose of the antenatal booking visit is to detect any risk factors that may
indicate the necessity of extra surveillance above that provided to ‘low-risk’
women. It is also an opportunity to identify any social difficulties and to
discuss the parents’ own wishes for the pregnancy and delivery.
- Past obstetric history
- Medical and surgical history
- Family history
- History of present pregnancy
- Social and drug history
- Mental health
- Examination
History
- Welcome the woman, and ensure a quite place where
she can express concerns and anxiety without being
overheard by other people.
- Personal and social history: This include: woman’s name, age, occupation, address,
and phone number. marital status, duration of
marriage, Religion , Nationality and language, Housing
and finance
Menstrual history
- Duration of menstruation.
- Cycle length.
- Regularity of the cycle
- LNMP (last normal menstrual period)
- EDD (expected date of delivery)
- Duration of pregnancy equql to 280 days since first day of LMP, 266 days
from day of ovulation.
- By adding 9 months and 7 days to first day of LMP we can calculate EDD,
provided regular 28 days cycle length. If for example cycle length of a
regular cycle is 21 days we add 9 months only. On the other hand sh has a
regular cycle of 35 days we add 9 months and 14 days to LMP.
Current problems with pregnancy :
Ask the patient if she has any current problem, such as:
- Nausea & vomiting.
- Abdominal pain.
- Headache.
- Urinary complaints.
- Vaginal bleeding.
- Edema.
- Backache.
- Heartburn.
- Constipation.
Obstetrical history:
This provides essential information about the previous
pregnancies that may alert the care provider to
possible problems in the present pregnancy. Which
includes:
- Gravida, para, abortion, and living children.
- Weight of infant at birth & length of gestation.
- Labor experience, type of delivery, location of birth,
and type of anesthesia.
- Maternal or infant complications.
Medical and surgical history:
- Chronic condition such as diabetes mellitus,
hypertension, and renal disease can affect the
outcome of the pregnancy and must be
investigated.
- Prior operation, allergies, and medications should be
documented.
- Previous operations such as cesarean section, genital
repair, and cervical cerclagc.
- Accidents involving injury of the bony pelvis
Family history:
Family history provides valuable information about
the general health of the family, and it may reveal
information about patters of genetic or congenital
anomalies.
Including:
- D.M.
- Hypertension.
- Heart disease.
- Cancer.
- Anemia.
Physical examination
Physical examination is important to:
- detect previously undiagnosed physical problems
that may affect the pregnancy outcome.
- and to establish baseline levels that will guide the
treatment of the expectant mother and fetus
throughout pregnancy.
General Examination
It should be started from the moment the pregnant
woman walks into the examination room.
Examine general appearance:
- Observe the woman for stature or body build and gait
- The face is observed for skin color as pallor and
pigmentation as chloasma.
- Observe the eyes for edema of the eyelids and color of
conjunctiva. Healthy eyes are bright and clear.
Vital signs:
- It is taken to ascertain normality and provide a baseline reading for a comparison throughout the
pregnancy.
- In late pregnancy, raised systolic pressure of 30 mm Hg or raised diastolic pressure of 15 mm Hg above the baseline values on at least two occasions of 6 or
more hours apart indicates toxemia.
- The normal pulse rate = 60-90 BPM.
- Tachycardia is associated with anxiety, hyperthyrodism, or infection.
- The normal is 16-24 BPM.
- Tachypnea may indicate respiratory infection, or
cardiac disease.
- normal temperature during pregnancy is 36.2C to
37.6C.
- Increased temperature suggests infection.
Cardiovascular system:
Which can develop into
varicosities, venous congestion
most commonly noted in the
legs, vulva, and rectum.
Edema of the extremities or face
necessitates further assessment
for signs of pregnancy-induced
hypertension.
Musculoskeletal system
Body mechanics and changes
in posture and gait should be
addressed. Body mechanics
during pregnancy may
produce strain on the
muscles of the lower back
and legs.
Height & weight:
An initial weight is needed to establish a baseline for weight gain throughout pregnancy.
Preconception:
- Wt. lower than 45kg, or Ht. under 150 cm is associated with preterm labor, and low birth weight infant.
- Wt. higher than 90 kg is associated with increased incidence of gestational diabetes, pregnancy induced hypertension, cesarean birth, and postpartum infection.
Recommendation for weight gain during pregnancy are often made based on the woman’s body mass index.
Observe the neck for enlarged thyroid gland and scars
of previous operations.
- Observe complexion for presence of blotches.
- Ensure that the general manner of the woman indicates
vigor and vitality.
- An anemic, depressed, tired or ill woman is lethargic,
not interested in her appearance, and unenthusiastic
about the interview.
- Lack of energy is a temporary state in early pregnancy, a
woman often feels exhausted and debilitated.
- Discuss the woman's sleeping patterns and minor
disorders and give advice as necessary.
- Report any signs of ill health.
Abdomen:
- The size of the abdomen is inspected
for:
- the height of the fundus, which
determines the period of the
gestation.
- multiple pregnancy.
- The shape of the abdomen is inspected for:
- fetal lie & position.
- the abdomen is longer if the fetal
lie is longitudinal as occurs in
99.5% of cases.
- the abdomen is lower & broad if
the lie is transverse.
- fetal movement is inspected as
evidence of fetal life and position.
- fetal heart beat can be heard by
stethoscope after the 20th week, or
Doppler after 8th week. Normal
fetal heart rate is 120-160
beats/min.
1-Inspection:
The nurse should look at the following:
- Skin changes such as linea nigra, striae
gravidarum and scars of previous operations.
- The size of the abdomen is inspected for:
- Height of the fundus, which determines the
period of gestation.
- Multiple pregnancy and polyhydramnios will
enlarge both the length and breadth of the uterus.
- A large fetus increases only the length of the
uterus.
- Contour of the abdominal wall is observed for
pendulous abdomen, lightening protrusion of
umbilicus and full bladder
2-Palpation :
The uterus will be palpable per abdomen after the
12th week of gestation
Abdominal palpation includes
- Estimation of the period of gestation. This is done by
determination of fundal height.
- Calculations:
- Calculation of gestation using fundal
height
- McDonald’s method: Measure from symphasis pubis to
top of fundus in cm.
- Gestation is measurement + or Gestation is measurement + or – 2 weeks
- 12 weeks :the uterus fills the
pelvis so that the fundus of the
uterus is palpable at the
symphysis pubis .
- 16 weeks, the uterus is
midway between the
symphysis pubis and the
umbilicus.
- 20 weeks, it reaches the
umbilicus
Skin
- Pallor of the skin my indicate anemia.
- Jaundice may indicate hepatic disease.
- Chloasma and linea nigra related to pregnancy.
- Striae graviderum should be noted.
- Nail beds should be pink with instant capillary
return.
Legs:
- Legs should be noted for edema.
- They should be observed for varicose veins
- The calf must be observed for reddened areas which may be
caused by phlebitis and white areas which could be caused
by deep vein thrombosis.
- Ask the woman to report tenderness during examination.
- The legs should be observed for unequal length or muscle
wasting which may be an indication of pelvic abnormalities.
Breast
Assess breast size, symmetry, condition of nipple,
and the presence of colostrum.
Gastrointestinal systems
- Mouth:
- The gum may be red, tender, edematous as a
result of the effects of increased estrogen.
Observe the mouth for:
- Dryness or cyanosis of the lips.
- Gingivitis of the gums.
- Septic focus or caries of the teeth
2. Intestine
- Assess for the bowel sound.
Assess for constipation or diarrhea.
3.Vaginal discharge:
- Ask the woman about any increase or change of
vaginal discharge.
- Report to the obstetrician any mucoid loss before
the 37th week of pregnancy.
4.Vaginal bleeding:
- Vaginal bleeding at any time during pregnancy
should be reported to the obstetrician to
investigate its origin.
Laboratory data
- Hemoglobin will be repeated:
- At 36 weeks of gestation.
- Every 4 weeks if HP is< 9 g/dL.
- If there is any other clinical reason.
Ultrasound
Is perform
- estimate the gestational age.
- Check amniotic fluid volume.
- Check the position of the placenta.
- Detect the multi-fetal pregnancy.
- The position of the baby.
Fetal kick count:
- The pregnant woman reports at least 10
movements in 12 hours.
- Absence of fetal movements precedes
intrauterine fetal death by 48 hours.
Schedule of antenatal care:
- a medical check up every four weeks up
to 28 weeks gestation,
- every 2 weeks until 36 weeks of gestation
- visit each week until delivery
- More frequent visits may be required if
there are abnormalities or complications
or if danger signs arise during pregnancy
Services at subsequent visits:
- the nurse inquires about physical changes that are
related directly to the pregnancy, such as the
woman’s perception of fetal movement, any
exposure to contagious illness, medical treatment
and therapy prescribed for non-pregnancy
problems since the last visit,
- prescribed medications that were not prescribed
as a part of the women’s prenatal care.
health education:
Advice the mother to follow up according to the schedule of
antenatal care that mentioned before, advise the mother to follow up
immediately if any danger sings appears, describe the important of
follow up to the mother.
Health teaching during
pregnancy
Health promotion during pregnancy begins with
reviewing health hare.
Hygiene:
- Daily all over wash is necessary because it is
stimulating, refreshing, and relaxing.
- Warm shower or sponge baths is better than tub bath.
- Hot bath should be avoided because they may cause
fatigue. &fainting
- Regular washing for genital area, maxilla, and breast due
to increased discharge and sweating.
- Vaginal douches should avoided except in case of
excessive secretion or infection.
Danger signs of pregnancy
- Vaginal bleeding including spotting.
- Persistent abdominal pain.
- Sever & persistent vomiting.
- Sudden gush of fluid from vagina.
- Absence or decrease fetal movement.
- Sever headache.
- Edema of hands, face, legs & feet.
- Fever above 100 F( greater than 37.7 C).
- Dizziness, blurred vision, double vision & spots before eyes.
- Painful urination.
Dental care:
- The teeth should be brushed carefully in the
morning and after every meal.
- Encourage the woman the to see her dentist
regularly for routine examination & cleaning.
- Encourage the woman to snack on nutritious foods,
such as fresh fruit & vegetables to avoid sugar
coming in contact with the teeth.
- A tooth can be extracted during pregnancy, but
local anesthesia is recommended.
Dressing:
- Woman should avoid wearing tight cloths such as
belt or constricting bans on the legs, because
these could impede lower extremity circulation.
- Suggest wearing shoes with a moderate to low
heel to minimize pelvic tilt & possible backache.
- Loose, and light clothes are the most comfortable.
Travel:
- Many women have questions about travel during
pregnancy.
- Early in normal pregnancy, there are no
restrictions.
- Late in pregnancy, travel plans should take into
consideration the possibility of early labor.
Exercises:
- Exercise should be simple. Walking is ideal, but
long period of walking should be avoided.
- The pregnant woman should avoid lifting heavy
weights such as: mattresses furniture, as it may
lead to abortion.
- She should avoid long period of standing because
it predisposes her to varicose vein.
- She should avoid setting with legs crossed because
it will impede circulation.
Purpose:
- To develop a good posture.
- To reduce constipation & insomnia.
- To alleviate comfortableness, postural back ache&
fatigue.
- To ensure good muscles tone& strength pelvic
supports.
- To develop good breathing habits, ensure good
oxygen supply to the fetus.
- to prevent circulatory stasis in lower extremities,
promote circulation, lessen the possibility of venous
thrombosis
Guide lines for exercises during pregnancy:
- Maintain adequate fluid intake.
- Warm up slowly, use stretching exercises but avoid over
stretching to prevent injury to ligaments.
- Avoid jerking or bouncing exercises.
- Be careful of loose throw rugs that could slip& cause
injury.
- Exercises on regular basis (three times per week).
- After first trimester, avoid exercises that require supine
position.
Contraindications:
- Vaginal bleeding.
- Sever anemia.
- History of preterm labor,
- Extreme over or under weight.
- Hypertension, heart, lung, thyroid diseases
Sleep:
- The pregnant woman should lie down to relax or sleep
for 1 or 2 hours during the afternoon.
- At least 8 hours sleep should be obtained every night
& increased towards term, because the highest level of
growth hormone secretion occurs at sleep.
- Advise woman to use natural sedatives such as: warm
bath & glass of worm milk.
- A good sleeping position is sims’ position, with the
top leg forward. This puts the weight of the fetus
on the bed, not on the woman, and allows good
circulation in the lower extremities.
- avoid resting in supine position, as supine
hypo-tension syndrome can develop.
Immunization:
the nurse instructs the woman to receive
immunization against -tetanus to prevent the
risk for her and her fetus.
Also, it is important that every pregnant
mother should receive a tetanus vaccination
card with her first tetanus dose and keep it to
record subsequent doses
