I now have everything I need for a thorough, structured ANC case assessment. Here is the complete response:
Assessment of an ANC (Antenatal Care) Case
A systematic ANC case assessment follows five major components:
1. Definition and Objectives
ANC is care provided by skilled health-care professionals to pregnant women to ensure the best health conditions for both mother and baby. It reduces maternal and perinatal morbidity and mortality by:
- Promoting, protecting, and maintaining maternal health
- Detecting "high-risk" cases and giving them special attention
- Foreseeing and preventing complications
- Reducing maternal and infant mortality and morbidity
- Teaching the mother elements of child care, nutrition, hygiene, and sanitation
- Sensitizing the mother to family planning needs
- Attending to under-fives accompanying the mother
- Park's Textbook of Preventive and Social Medicine, p. 612
2. Antenatal Visits Schedule
Ideal: Once a month for 7 months, twice a month in the 8th month, then weekly.
Minimum 4 visits (recommended schedule):
| Visit | Timing | Purpose |
|---|---|---|
| 1st | Within 12 weeks | Registration, history, 1st check-up |
| 2nd | 14-26 weeks | Routine check-up |
| 3rd | 28-34 weeks | Medical officer review (high-risk screening) |
| 4th | 36 weeks to term | Pre-delivery assessment |
- Park's Textbook of Preventive and Social Medicine, p. 612
3. Components of Assessment at Each Visit
I. History Taking
- LMP (Last Menstrual Period) - to calculate Expected Date of Delivery (EDD)
- Obstetric history: parity, previous deliveries, complications, abortions
- Medical history: cardiovascular disease, diabetes, TB, kidney disease, malaria, HIV, RTI/STI
- Current symptoms: bleeding, pain, swelling, headache, reduced fetal movements
II. General Physical Examination
| Parameter | What to Assess |
|---|---|
| Height | Measured at 1st visit; short stature (<145 cm) = risk factor |
| Weight | At every visit; normal gain = 9-11 kg total; ~2 kg/month after 1st trimester |
| Pallor | Check conjunctiva, tongue, nails for anaemia |
| Oedema | Feet, legs, face, hands - if with hypertension/proteinuria = pre-eclampsia |
| Blood Pressure | At every visit; BP ≥140/90 mmHg on two readings = hypertension; BP ≥110 mmHg diastolic = danger sign (imminent eclampsia) |
| Respiratory Rate | Check at each visit |
| Breast Examination | Nipple shape - flat or inverted nipples |
Note on weight gain: Gain <2 kg/month = suspect inadequate diet/IUGR; >3 kg/month = suspect pre-eclampsia, twins, or gestational diabetes.
III. Abdominal Examination
Fundal height - correlates with gestational age:
| Weeks | Fundal Height |
|---|---|
| 12 weeks | Just palpable per abdomen |
| 20 weeks | At lower border of umbilicus |
| 24 weeks | At umbilicus |
| 36 weeks | At xiphisternum level |
| 40 weeks | Slightly below xiphisternum (lightening) |
Other abdominal assessments:
- Lie of fetus (longitudinal, transverse, oblique)
- Presentation (cephalic, breech)
- Engagement of presenting part (at or after 36 weeks)
- Fetal Heart Rate (FHR): Normal 120-160 bpm; checked by Pinard's stethoscope or Doppler
- Uterine size vs gestational age discrepancy (large = twins/hydramnios; small = IUGR/oligohydramnios)
IV. Assessment of Gestational Age
- LMP-based EDD: Naegele's rule - add 9 months and 7 days to LMP (or +280 days)
- Fundal height measurement (tape measure in cm from pubic symphysis = approximate weeks)
- Gold standard: First trimester ultrasound using fetal measurements (CRL in 1st trimester, BPD/FL in 2nd trimester)
- "Best obstetric estimate" = combining LMP and USG
V. Laboratory Investigations
At Sub-centre level:
- Pregnancy detection test
- Haemoglobin (Hb) estimation
- Urine for albumin and sugar
- Rapid malaria test
At PHC/CHC/FRU level:
- Blood group + Rh factor
- VDRL/RPR (syphilis)
- HIV testing
- Blood sugar (fasting/random)
- HBsAg (Hepatitis B)
- TB skin test (if available)
4. High-Risk Case Identification
The following factors flag a pregnancy as high-risk (requiring referral/extra care):
- Age <18 or >35 years; height <145 cm; weight <38 kg
- Haemoglobin <7 g/dL (severe anaemia)
- Primigravida or grand multipara (4+ deliveries)
- Previous bad obstetric history (stillbirth, neonatal death, manual removal of placenta, previous LSCS)
- Pre-eclampsia or eclampsia (current or past)
- Multiple gestation (twins)
- Prolonged pregnancy (>14 days past EDD)
- Medical co-morbidities: cardiac disease, diabetes, TB, HIV, renal disease, malaria
- Three or more consecutive spontaneous abortions
- Treatment for infertility
5. Preventive Interventions (Services Provided)
| Intervention | Schedule/Details |
|---|---|
| IFA tablets | 100 mg elemental iron + 0.5 mg folic acid daily from 12 weeks till 6 months postpartum |
| Folic acid | 0.4 mg/day in 1st trimester (pre-conception and up to 12 weeks) |
| Tetanus Toxoid (TT) | TT1 early in pregnancy; TT2 four weeks after TT1 (if previously unvaccinated) |
| Calcium supplementation | 500 mg elemental calcium daily from 2nd trimester |
| Albendazole | Single 400 mg dose in 2nd trimester (after 14 weeks) for deworming |
| Malaria prophylaxis | In endemic zones per NVBDCP guidelines |
6. Counselling Points (Prenatal Advice)
- Diet: Extra 350 kcal/day in 2nd trimester, extra 500 kcal/day in 3rd trimester; protein-rich diet; avoid raw/unpasteurized foods
- Rest: 8+ hours sleep; avoid heavy lifting; 1-2 hours rest in afternoon
- Minor complaints: Nausea, heartburn, constipation, backache management
- Tobacco/alcohol cessation
- Danger signs (requiring immediate referral): Vaginal bleeding, severe headache, blurred vision, convulsions, severe abdominal pain, high fever, reduced fetal movements, facial/hand swelling
- Institutional delivery planning
- Family planning counselling
- JSY/government scheme information
- HIV and RTI/STI counselling
7. Record Keeping
- Mother and Child Protection (MCP) Card completed at registration and updated at each visit
- Records baseline BP, weight, Hb, LMP, EDD, risk factors
- The card is carried by the mother at all visits and to the delivery
- Recorded in the antenatal register (HMIS format)
