This document provides information on antenatal care including definitions, objectives, components, strategies and high risk pregnancies. It begins with defining antenatal care and listing its objectives such as promoting mother and baby health, detecting high-risk cases, preventing complications, reducing mortality and morbidity.
Components of antenatal care include risk identification, preventing/managing pregnancy diseases, and health education. Strategies involve antenatal visits, prenatal advice, specific health protections, mental preparation and family planning. High risk pregnancies are identified based on maternal medical conditions, obstetric history, current pregnancy complications, and certain signs. The document outlines the steps for antenatal exams, tests, advice and identifying warning signs.

4. INTRODUCTION
• Definition
“the systematic supervision of women during pregnancy to monitor the progress of foetal
growth and to ascertain the wellbeing of the mother and foetus”
• Antenatal period - from the time of conception to the onset of labour
• Aim –
• To preserve the physiological aspect of pregnancy and labour
• To prevent or detect all pathological disorders as early as possible
• To achieve a healthy mother and a healthy baby
• Early diagnosis during pregnancy can prevent maternal mortality, foetal death,
infant mortality and morbidity

9. OBJECTIVES
12
1. To promote, protect
and maintain the
health of the mother
during pregnancy
2. To detect "high-
risk" cases and give
them special attention
3. To foresee
complications and
prevent them
4. To remove anxiety
associated with
delivery
10. OBJECTIVES
13
5. To reduce maternal and
infant mortality and
morbidity
6. To teach the mother
elements of childcare,
nutrition, personal hygiene
and environmental
sanitation
7. To sensitize the mother
to the need for family
planning, including advice
to cases seeking medical
termination of pregnancy
8. To attend to the under-
fives accompanying the
mother
12. HOME VISITS
15
Backbone of all MCH services
Even if the expectant mother is attending the antenatal clinic regularly, it is suggested that she
must be paid at least one home visit by the Health Worker Female or Public Health Nurse
More visits are required if delivery is planned at home
Benefits:
Mother is generally relaxed at home
Home visit will win her confidence
Opportunity to observe the environmental (separate room,
lighting, ventilation, cattle, water supply) and social conditions
Opportunity to give prenatal advice
13. 1.VISITS
To confirm pregnancy - urine examination
• On the basis of presence of human chorionic
gonadotrophin hormone in the urine
• Nishchay- GOI Program Under NRHM MOHFW
• Home based 5 minute pregnancy test card
• Free of cost kit are made available at public health care
system accessed through ASHA/ANM
• Objective- Early detection of pregnancy and take
necessary action
• Rationale - To address the anxiety due to delayed or
missed menstrual cycle

17. Importance
of detection
of early
pregnancy
Confirm if the pregnancy is wanted and if not, then refer the
women at the earliest to a 24 hours PHC or FRU that provides
safe abortion services to avoid illegal abortions
Facilitates proper planning and adequate care during
pregnancy for both mother and foetus
Record the date of LMP and calculate EDD
Assessment of mother’s health status to detect medical or
surgical illness
Obtain and record the baseline information
(BP, weight, haemoglobin)
Timely detection of complications at an early stage so as to
manage them appropriately by referral as and when required
Good interpersonal relationship between the care giver and
the pregnant woman
20
18. Estimation of number of pregnancies in a
specified area and pregnancy tracking
21
To ensure complete registration
ANM should know the estimated number of pregnancies to be
registered annually in her area
Significance:
• Judge how good her pregnancy registration is
• Adequate stock of the supplies required to provide routine ANC (such as
TT injections, IFA tablets and ANC record forms)
• Tackle any complications that arise during this period
19. Number of expected pregnancies
per year :
• Expected number of live births
= Birth rate (per 1000 population) x population of the area /1000
• As some pregnancies may not result in a live birth (i.e. abortions and stillbirths
may occur), the expected number of live births would be an under-estimation of the
total number of pregnancies
• Correction factor of 10% is required, i.e. add 10% to expected number of live
births
• As a rule, in any given month, approximately half the number of pregnancies
estimated above should be in records
20. Preventive services
for mothers
1. History taking
2. Physical examination
3. Abdominal examination
4. Assessment of gestational age
5. Laboratory investigations
23
21. 1.History-
taking
1. Age
2. Type of marriage - non/consanguineous
3. Obstetric score
4. Identify complications during previous
pregnancy/confinement
5. Identify any existing medical/ surgical or
obstetric condition
6. Calculate the expected date of delivery =
LMP + 9 months + 7 days
7. Calculate POG – in completed weeks
8. Record symptoms indicating complications
9. Record family history of hypertension,
diabetes, tuberculosis, and thalassaemia;
twins or congenital malformation
10.History of drug intake or allergies
24
22. 2.Physical examination
Pallor
Icterus
Pulse :
• Normal - 60 to 90 beats/min
• Persistently low or high, with or without other symptoms, the woman needs referred
Respiratory rate :
• Normal - 18-20 breaths/min.
• Especially with complaints of breathlessness
Oedema :
• Physiological – Lower limbs appears in the evening and disappears in the morning after a full night's
sleep
• Pathological - face, hands, abdominal wall and vulva
• Associated with high blood pressure, cardiac pathology, anaemia or proteinuria, the woman should
be referred to the medical officer
• Non-pitting oedema – Hypothyroidism and filariasis 25
23. 2.Physical examination
6. Blood pressure :
• Measure at every visit
• To rule out hypertensive disorders of pregnancy
• Hypertension –
2 consecutive readings taken 4 hrs apart show systolic blood pressure
to be ≥140 mmHg and/or the diastolic blood pressure to be ≥ 90
mmHg
• Signify - Pregnancy-Induced Hypertension (>20wks POG) and/or
chronic hypertension(<20wks POG)
• Check her urine for albumin
• Pre-eclampsia –
Presence of albumin (+2 or ≥0.1g/L ) + high B.P.
• Eclampsia – Pre-eclampsia + convulsion and/or coma
26
24. 2.Physical examination
7. Weight :
• Checked at each visit
• Weight taken during the first visit/ registration should be treated as the
baseline weight
• Normally - gain 9-11 kg
• Ideally, after the first trimester, gains 2 kg every month
• Inadequate dietary intake can be suspected if the gain is <2 kg/month
• Leads to Intrauterine Growth Retardation and thus a low birth weight
baby
• Excessive weight gain (>3 kg in a month) should raise suspicion of
multiple pregnancy, preeclampsia or diabetes
27
25. 2.Physical examination
8. Breast examination :
• To prevent feeding difficulties postnatally
• Observe the size and shape of the nipples
• Flat nipples – Rolled out manually, do not
interfere with breast feeding
• Inverted – has to be corrected as breast
feeding will be disturbed
• Crusting and sore nipples – breast hygiene
and emollients
28
26. 3.Abdominal examination
• To monitor the progress of the
pregnancy and foetal growth
• Helps confirming the calculated
duration of pregnancy
• Includes the following :
1. Inspection: Scar ; Linea nigra, striae
gravidarum
2. Measurement of fundal height :
Enlargement of the uterus and the height of
the uterine fundus
3. Foetal heart sounds : Heard after 20 weeks;
Normal - 120 to 140 beats/min
4. Foetal movements : Appreciated 18-22nd
week by gently palpation
5. Foetal parts : Felt after 22nd week and after
the 28th week, it is possible to distinguish
the head, back and limbs
6. Foetal lie and presentation : Relevant only
after 32 weeks of pregnancy
29

30. RISK APPROACH
• “Managerial tool based on the strategy for efficient
utilization of scarce resources with more care for
those in need and proportionate to the need”
• Mothers and children are most susceptible to good or
harmful influences that will permanently affect their
health
• These influences can be promoted in a very short time
• Thus preventive and promotive elements of primary
health care will have greatest yield if applied by using
risk approach in MCH
