1. ANTENATAL CARE IN TANZANIA
• Care given to a pregnant woman.
• It is a systematic supervision of a woman
during pregnancy.
• It comprises of
– Careful history taking and examinations
– Ear-marking the high-risk group
– Advice given to the pregnant woman.
2. Aims of ANC
• To screen the ‘high risk’ cases in pregnancy.
• To prevent or to detect and treat at the earliest
any complications of pregnancy
• To ensure that the pregnant woman reaches the
end of her pregnancy healthy.
• To educate the mother about the physiology of
pregnancy and labour
• To advice on the place, time and mode of
delivery, provisionally and care of the newborn.
3. Specific objectives
• To ensure a good standard of health to all
pregnant women
• To observe any abnormality in the pregnancy and
advise the woman the best course of action
thereafter.
• To deal with any common illnesses during
pregnancy
• To make the mother aware of the benefits
offered by antenatal , postnatal and family
planning clinics.
4. Normal pregnancy
• Delivery of a single baby in good condition at
term (between 38-42) , with fetal wt of ≥
2.5kg and with no complication
5. 1.FIRST VISIT
• Activities include
– Registration
– Wt and ht measurement
– History taking
– Physical examination
– Lab investigation
– Mgt of minor complaints
– Prophylactic rx
– Immunization
– Health education
6. Physical examination
1. General examination
• Pts general appearance
– Whether ill-looking or not
– Short stature
– Whether she walks in a limp.
• Nutritional status
– Check signs of wasting- zygomatic bones, wasted
intercostal spaces, and hypothenar and thenar
muscles.
7. • Blood pressure –
• BP ≥140/90 is considered abnormal
• Signs of anaemia
– Look for clinical anaemia in the
conjuctivae, tongue, mouth, palms, fingernails, sol
es of the feet and even the vaginal wall.
• Look for oedema of the ankles, sheen of
tibia,sacral area, anterior abdominal wall and
periorbital area.
8. 2. Systemic examination
– CVS- check PR, size of the heart, heart sounds
and murmurs
– RS – rule out PTB and any lung lesions.
– MSS- check the pelvis structure and the
spine, rule out bony abnormalities.
– CNS- should be examined if indicated
9. Obstetric examination
• Inspection of the abdomen
– Check and record any scars, superficial irregularities or over-
distension
• Height of the fundus
– The fundal height is compared with the GA in weeks as
calculated from L.N.M.P
• Lie of the fetus
– Relationship of the long axis of the fetus to that of the mother.
– Indicates whether the fetus is upright(longitudinal) or lying
crosswise(transverse) or obliquely.
– It is most important after 32 weeks , by which time it should
have settled into a longitudinal lie.
10. • Presenting part
– Part of the fetus that is at the pelvic brim.
– It will be either cephalic, or breech( buttocks)
• Attitude of the fetus parts
– Relation of the fetal parts to one another.
– If the head is bent so that the chin is touching the
chest , it is said to be flexed.
– A well flexed head presents the smallest diameter
and delivers easier
11. Investigations
Initial routine investigations for each pregnancy at first antenatal visit
(obtain informed consent for each test): include
• • Full blood picture-for Hb estimation
• • Blood group and atypical antibody screen
• • Syphilis serology (VDRL tests)
• • Rubella titre
• • Hepatitis B surface antigen
• • Hepatitis C antibodies
• • HIV antibodies for PMTCT
• • Random blood glucose (if mod/high risk of diabetes)
• • Midstream Urine for protein
• • Chlamydia screening
• Stool examination for hookworms and ascaris ova.
12. • Investigations to be considered depending on the
woman’s clinical circumstances:
• Early dating ultrasound if dates uncertain
• Vitamin D screening if at risk for Vitamin D deficiency
e.g., women who have reduced sun exposure, veiled
women and dark skinned women
• Pap smear (if not done within two years)
• Diabetes screening as indicated
• Haemoglobinopathy Screening if in high-risk group
e.g. high risk ethnic background, FHx of
haemoglobinopathy
13. Management of minor ailments in
pregnancy.
1. Morning sickness
a) woman should take small frequent meals
b) She should take lots of fluids
c) She should aviod heavy meals or staying hungry for long
time.
2. Heart burn
a) She should use many pillows to raise her head when
sleeping
b) To take small sips of milk or warm water
c) To avoid over eating and not to go to bed
immediately after eating.
d) Liquid antacids may be helpful.
14. Routine prophylaxis
Malaria
Pregnant women should be given sulfadoxine
pyrimethamine (SP) as intermittent preventative
treatment (IPT) as follows:
First single dose after 16-20 weeks
Second single dose after 30 weeks
Anaemia
Give iron tablets like ferrous sulphate 600mg daily in
divided doses throughout pregnancy. This should also
depend on the Hb level. Hb level < 10.0mg/dl give
thrice a day.
Give 5mg folic acid daily throughout pregnancy.
15. Immunization
Tetanus Toxoid
• To prevent tetanus neonatorum.
• So it is recommended to give TT to all mothers
• WHO TT immunization schedule.
• This should be started for all school attending
girls so that by the time they get into
reproductive age they are fully immunized
against tetanus.
16. WHO TT IMMUNIATION SCHEDULE.
Dose When to give % of protection Duration of
Protection
TT---1 At 1st contact or as Nil None
early as possible
during pregnancy
TT--2 At least 4 weeks 80% 3 years
after TT--1
TT--3 At least 6 months 95% 5 years
after TT--2
TT---4 At least 1 year after 99% 10 years
TT--3
TT--5 At least 1 year after 99% 20 years
TT--4
17. • For mothers who have never been vaccinated
before, give 3 doses of 0.5 cc IM toxoid at
intervals of at least 1 month. The last dose
should be given during the last 2 months of
pregnancy.
• For those who have been vaccinated before, a
booster dose of 0.5cc IM is given in the last
trimester.
18. ARV DRUGS
• It is recommended that pregnant women who
are HIV +ve take Nevirapine tablets 200mg
during labour and the newborn is given
nevirapine syrup 0.2mg/kg body wt within 72
hours after delivery
19. ANTI-D IMMUNIZATION
• Anti-D
• It is recommended that anti-D (625 IU) be given to all rhesus
negative, antibody negative women at 28 and 36 weeks gestation. These
women will therefore need to be seen at 28 weeks and 36 weeks.
• Anti-D is also given to these women after the birth of their baby if the
baby is rhesus positive.
• A blood test for blood group and antibodies needs to performed prior to
administering the 28 week dose of anti-D.
• It is recommended that anti-D is given to all rhesus negative and antibody
negative women if there is risk of fetal-maternal transfusion of blood, such
as a miscarriage.
• Anti-D should be given within 96 hours of the onset of bleeding (the
earlier the better)
20. Anti-D dosage
First trimester – 250 IU (minidose vial).
• Indications are threatened or inevitable
miscarriage, termination of pregnancy,
chorionic villus sampling and ectopic
pregnancy.
• Note: For a multiple pregnancy give 625 IU.
21. Anti-D dosage
• Second and third trimester, postnatally – 625 IU
(full dose vial).
• Indications are at 28 weeks, 36 weeks, postnatally
(if baby is rhesus positive) and episodes when a
fetal-materal haemorrhage may occur such as
amniocentesis, external cephalic version,
antepartum haemorrhage or abdominal trauma.
• Note: For second and third trimester, a Kleihauer
test should be performed (1-24 hours after the
bleeding or sensitising event) so additional anti-D
may be given if required.
22. SUBSEQUENT VISIT
• The pregnant woman should be encouraged
to re-visit ANC.
• After each visit the woman should be told the
date of her next visit and the date written on
her ANC card which she takes home.
• It is every 4 weeks until 28 weeks then every 2
weeks until 36 weeks and weekly thereafter
till delivery.
23. • The activities during re-visit periods are as
during the first visit but brief.
• The schedule for seeing pregnant women
should be at least 4 according to WHO in
developing countries.
1. In the 1st trimester around 16 weeks—First visit
2. Between 24-28 weeks—2nd visit
3. At 32 weeks –3rd visit
4. At 36 weeks---4th visit.
24. Objectives of re-visit
• To assess
– Fetal well being
– Fetal lie, presentation, position and # of fetuses
– Anemia, pre- eclampsia, amniotic fluid volume
and fetal growth
• To organise specialist antenatal clinics for pts
at high risks
• To select time for USS, amniocentesis or
chorion villus biopsy when indicated.
25. High- risk group
• Are pregnant women whose pregnancies are
at higher-risk of having complications that
affect the pregnancy outcome –maternal or
perinatal or both.
