Antenatal Check-up

Obstetrics & Gynecology

Systematic care of pregnant woman aimed at maintaining health, identifying risk, preventing complications.

History taking

  • LMP, EDD (Naegele), parity, prior pregnancies/outcomes
  • Current symptoms (nausea, bleeding, leaking, fetal movements)
  • Medical/surgical/family history; medications; allergies; vaccinations
  • Social: nutrition, smoking, alcohol, domestic violence screening

Examination

  • BP, weight, BMI, pallor, oedema
  • Abdominal: fundal height (after 12 wk), Leopold maneuvers (after 28 wk), fetal heart
  • Per speculum/vaginal as indicated

Red flags

  • Severe headache, blurred vision, epigastric pain (pre-eclampsia)
  • Bleeding, leaking, decreased fetal movements
  • Fever, severe vomiting

Differential diagnosis

  • Threatened miscarriage, ectopic, gestational HTN, anaemia, GDM, antepartum haemorrhage

Recommended investigations

  • First visit: CBC, blood group/Rh, urinalysis, HIV, VDRL, HBsAg, RBS/OGTT, TSH
  • USG: dating (8–12 wk), NT/anomaly (11–14, 18–22 wk)
  • OGTT 24–28 wk, anti-D antibody screen Rh-negative

Diagnosis

  • Confirm pregnancy with urine/serum hCG; date by LMP + early USG

Initial treatment / management

  • ≥4 ANC visits (WHO recommends 8); ideally monthly until 28 wk, fortnightly to 36 wk, weekly thereafter
  • Folic acid 400 µg preconception–12 wk (5 mg if high risk)
  • Iron 60 mg + Folic acid 500 µg daily from 14 wk
  • Calcium 1 g/day; vaccinations (Tdap 27–36 wk, influenza)
  • Anti-D at 28 wk if Rh-negative

Prescription examples

  • Tab Folic Acid 5 mg PO OD (until 12 wk)
  • Tab Iron + Folic Acid 60 + 500 mcg PO OD from 14 wk
  • Tab Calcium 500 mg PO BD
  • Tab Doxinate (Doxylamine + Pyridoxine) PO HS for nausea

Follow-up advice

  • Each visit: BP, weight, fundal height, fetal heart, urine dipstick
  • Schedule USG, OGTT, Tdap as per gestational age

Patient counselling

  • Nutrition, weight gain, exercise, sleep, hygiene
  • Danger signs and where to seek emergency care
  • Birth preparedness, breastfeeding, contraception postpartum

Referral criteria

  • High-risk pregnancy: HTN, diabetes, anaemia, multiple gestation, prior CS, age extremes
  • Suspected pre-eclampsia, IUGR, malpresentation

Clinical pearls

  • BP ≥140/90 after 20 wk + proteinuria = pre-eclampsia; urgent referral
  • Universal screening for GDM at 24–28 wk in India (DIPSI/IADPSG)
