The main objectives of antenatal care are:
• Identification of high-risk pregnancy
• Prevention and treatment of any complications
• Emergency preparedness
• Birth planning
• Satisfying any unmet nutritional, social, emotional and physical needs of the pregnant woman
• Provision of patient education, including successful care and nutrition of the newborn
• Encouragement of (male) partner involvement in antenatal care
Goal-Oriented Antenatal Care Protocol
• Goals for ANC vary depending on the timing of the visit/duration of pregnancy
• In normal (uncomplicated) pregnancies, aim for 4 routine visits as follows:
Antenatal visit |
Week of pregnancy |
1st |
10-16 |
2nd |
20-28 |
3rd |
28-36 |
4th |
>36 |
• If a woman comes for first ANC later than the 1st trimester, combine and attend to the preceding goals
• At all visits: address identified problems, check BP, and measure the symphysiofundal height (SFH)
• Encourage the woman to brnig her partner or a family member to at least one visit
First antenatal visit (between weeks 10-16)
Goals
• Risk assessment
• Health education
• Plan for delivery
History taking
• Record name, age, marital status, occupation, education, ethnic origin, residence
• Enquire if patient has any problems and obtain details
• Medical history:
- include family history of diabetes, hypertension, TB, hereditary diseases, multiple pregnancy
• Surgical history
• Obstetric and gynaelogical history:
- record for each pregnancy: date, place, maturity, labour, delivery, weight, sex and fate of the infant, and any puerperal morbidity
• Current pregnancy:
- record history of current pregnancy: date of (first day of) last menstrual period (LMP), date of conception
- confirm period of gestation/present maturity (= no of weeks from LMP)
- calculate estimated delivery date (EDD) by adding 7 days to the LMP and 9 months to the month of LMP. eg. LMP = 1/1/02, EDD = 8/10/02 Where the months total is >12, subtract 12 from this, eg. LMP = 5/5/02, add 9 months = 5+9 = 14, subtract 12 months = 14-12 = 2, therefore EDD = 12/2/03
- any problems encountered, eg. bleeding
• Contraceptive use
• Check for STIs
• Social history:
- smoking, (alcohol) drinking, drug use habits
Examination
• General physical examination, BP, weight, breasts
• Obstetric examination: symphysiofundal height (SFH), lie, presentation, foetal heart sounds, presence of multiple gestation
• Vaginal (vulval) examination (only carry out if indicated; use a speculum) as follows:
- in early pregnancy: to confirm and date the pregnancy
- in late pregnancy: to assess pelvic adequacy
- in labour: to confirm diagnosis and monitor
- other times: to evaluate symptoms/complaints
• Abdominal examination: to look for Caesarian scar, rule out multiple pregnancy
Laboratory investigations
Blood: for ABO, rhesus grouping, RPR (syphilis), Hb
Urine: for albumin, glucose
Other tests - as appropriate for the individual patient to assess maternal well-being, eg. ultrasound, amniotic fluid, foetal heart/movements
Management of common complaints (see table over)
Health promotion
• Address any problems
• Involve husband in ANC
• Draw up delivery plan
• Discuss future family planning (FP) (see p424)
• Discuss symptoms of miscarriage, pregnancy-induced hypertension (PIH)
• Educate & counsel on PMTCT of HIV
• Proper nutrition:
- eat more and greater variety of foods, have an extra meal each day
- advise against any taboos regarding nutritionally important foods
• Adequate hygiene
• Breastfeeding and breastcare
• Sexual activity during pregnancy
• Avoidance of smoking
Routine medication
