Antenatal Care in Reproductive Health

Table of Contents

Antenatal Care :

Antenatal care refers to a structured healthcare program designed for pregnant individuals. It aims to ensure a healthy and positive experience throughout pregnancy and childbirth

Importance of Antenatal Care: Accessible and effective antenatal care (ANC) is crucial for improving maternal health. ANC is a fundamental element for promoting safer motherhood globally. Offering flexible options for consultation locations and appointment times could significantly increase attendance and improve satisfaction for expectant mothers. Health ministries advocate for integrated service delivery, incorporating elements like family planning, prevention of mother-to-child transmission (EMTCT) interventions within antenatal care, and immunization programs.

Aims/Purposes of Antenatal Care

  1. Health Promotion: To enhance and maintain the physical, mental, and social well-being of women during pregnancy.

  2. Early Detection & Treatment: To identify and manage any pre-existing conditions or health issues that may arise during pregnancy, whether they are medical, surgical, or obstetric in nature.

  3. Birth Preparedness: To equip mothers for a safe childbirth experience, including preparation for potential emergencies and complications.

  4. Healthy Baby, Healthy Mother: To facilitate the delivery of a healthy, full-term infant (or infants) while minimizing health risks for the mother.

  5. Postpartum & Newborn Care: To support mothers through the normal postpartum period and, in collaboration with their partners, enable them to provide optimal physical, psychological, and social care for their child.

  6. Deviation Management & Privacy: To identify any deviations from normal pregnancy progression and provide necessary management or treatment, while consistently ensuring patient privacy.

  7. Breastfeeding Preparation: To prepare mothers for successful breastfeeding and offer guidance on adequate lactation preparation.

  8. Nutritional Guidance: To provide mothers with essential nutritional advice for a healthy pregnancy.

  9. Parenthood Counseling: To offer parenthood advice, whether through structured programs or individual consultations, tailored to the client’s specific concerns.

  10. Building Trust & Communication: To foster a strong, trusting relationship between the family, the pregnant woman, and healthcare providers. This encourages open communication and allows them to share anxieties and concerns related to the pregnancy and care received through effective communication and counseling.

  11. Preventive & Advisory Services: To provide pregnant women with ongoing preventive and advisory services. Healthcare providers should discuss suitable birth locations and essential preparations for a clean and safe delivery, such as the use of birth kits.

Goals of Focused/Oriented Antenatal Care

Important Considerations: Goals are visit-specific and adapted based on the timing of each antenatal appointment. For uncomplicated pregnancies, a schedule of 4 visits is generally recommended. Women initiating care later in pregnancy will require a combination and prioritization of goals from earlier visits. During every visit, any identified health concerns should be addressed, and blood pressure (BP) and symphysio-fundal height (SFH) should be routinely checked.

Overarching Goals for Maternal and Newborn Health: To improve maternal and newborn survival through:

  • Early Problem Detection: Prompt identification and treatment of pregnancy-related problems and complications.

  • Complication Prevention: Strategies to prevent the occurrence of complications and diseases during pregnancy.

  • Birth Preparedness & Emergency Readiness: Ensuring mothers are prepared for childbirth and ready to handle potential complications.

Scheduling and Timing of Goal/Focused Antenatal Care Visits

  • First Visit: By 16 weeks of gestation at the latest, ideally as soon as a woman suspects pregnancy (0-16 weeks).

  • Second Visit: Between 16-28 weeks gestation, or at least once during the second trimester.

  • Third Visit: Between 28-32 weeks gestation.

  • Fourth Visit: Additional visits are scheduled as needed based on individual circumstances. This includes:

    • Occurrence of complications.

    • Need for follow-up care or referral.

    • Patient request to see a healthcare provider.

    • Changes in care plan based on assessment findings (history, examination, tests) or local guidelines.

  • Referral: Prompt referral to specialized care when necessary.

Antenatal Risk Assessment

Antenatal risk assessment is a systematic evaluation of pregnant women during antenatal care to identify those at higher risk of adverse pregnancy outcomes during childbirth. It also involves detecting and managing any illnesses or pregnancy complications as they arise.

First Antenatal Visit/Booking Visit

The primary goal of the first antenatal visit is to establish baseline information for each woman, against which subsequent findings will be compared and assessed throughout her pregnancy.

This baseline information is obtained through:

  1. ✔ History Taking

  2. ✔ Physical Examination: General, systemic, and abdominal examination.

  3. ✔ Investigations (laboratory tests).

1. History Taking

A structured and comprehensive history is essential to evaluate the health status of both the mother and the fetus. Key components of the history include:

✔ Demographic Information: Name and place of residence, noting accessibility to healthcare and maternity services.
✔ Age: Identifying high-risk age groups (under 18 and over 35 years).
✔ Parity: Noting young and elderly primigravidas, women with parity above 4, and closely spaced pregnancies (less than 2 years apart).
✔ Social History: Marital status, sources of social and financial support, education level, history of female genital mutilation (where applicable), alcohol and tobacco use, and partner’s health status.
✔ Medical History: Prior medical conditions such as hypertension, renal disease, epilepsy, diabetes mellitus, sickle cell disease, asthma, Tuberculosis (TB), and HIV. Surgical history, including operations, blood transfusions, skeletal deformities, and fractures of the pelvis, spine, or femur.
✔ Obstetric and Gynecological History: Details of previous pregnancies and their outcomes, such as prior Cesarean sections, retained placenta, PPH, stillbirth, prolonged labor, early maternal death, ectopic pregnancies, Dilatation and Curettage (D&C), APH, pre-eclampsia, etc.
✔ Family History: Family history of conditions like hypertension, diabetes, multiple pregnancies (twins), and sickle cell disease.
✔ Menstrual History:
1. Detailed menstrual history including age at menarche, cycle length and regularity, duration and amount of menstrual flow.
2. Contraceptive history: Past use of modern contraceptive methods and dates of discontinuation.
✔ History of Present Pregnancy: Information about the first day of the Last Normal Menstrual Period (LNMP) to calculate the Estimated Date of Delivery (EDD). This helps in comparing gestational age with fundal height during examinations. If pregnancy is beyond 20 weeks, note the dates of quickening (first fetal movements felt by the mother). Inquire about any problems experienced since becoming pregnant, such as bleeding, vomiting, hospitalization, HIV sero-status, fever, cough, or diarrhea.

2. Physical Examination

General Examination:

A head-to-toe physical examination to assess overall health and identify any non-pregnancy-related illnesses:

✔ Weight Measurement: Note underweight (below 45 kg) or overweight (above 80 kg) women.
✔ Height Measurement: Identify women with short stature (below 159 cm) and check for skeletal deformities or limping.
✔ Blood Pressure Measurement: Identify women with elevated blood pressure (BP ≥ 140/90 mmHg).
✔ Anemia and Jaundice Assessment: Examine conjunctiva, tongue, palms, and capillary refill in nail beds to check for anemia and jaundice.
✔ Edema Assessment: Check for swelling (edema) in feet, hands, face, and sacral area.
✔ Systemic Examination: Systematic examination of respiratory and cardiovascular systems to rule out abnormalities.
✔ Breast Examination: Examine breasts for masses and signs of malignancy. Educate women on nipple care and breast self-examination.
✔ Physical Abuse Assessment:
1. Screen for drug abuse.
2. Check for unexplained bruising.
✔ Assessment of Any Complaints: Address any specific complaints reported by the woman.

 

3. Abdominal Examination

The abdomen should be fully exposed to visualize key landmarks.

  1. ✔ Inspection: Observe the abdomen for:

    • Size and shape of the abdomen.

    • Presence of scars indicating previous uterine surgery.

    • Visible fetal movements.

  2. ✔ Palpation: Palpate the abdomen to note:

    • Presence of enlarged liver, spleen, or renal angle tenderness.

    • Fundal height measurement and comparison with gestational age. Excessive abdominal enlargement may suggest multiple gestation or polyhydramnios (excess amniotic fluid).

    • Fetal lie, presentation, position, any tenderness, and estimation of amniotic fluid volume.

  3. ✔ Auscultation: Listen to fetal heart sounds, noting rate, volume, and rhythm.

Inspection of the Vulva

Visually examine the vulva to detect lesions, vaginal discharge, and any perineal or vulval scars. If abnormal discharge is present and laboratory facilities are available, obtain a specimen for Gram stain analysis. If lab services are unavailable, utilize the STI syndromic management approach to provide appropriate treatment to the mother.

Laboratory Investigations during Antenatal Care

Baseline Investigations: (Routine for all pregnant women)

  • Hemoglobin (Hb) level (normal range: 10.5-15 g/dL).

  • Blood group and Rh factor (ABO and Rhesus).

  • Urinalysis (for protein and glucose).

  • Venereal Disease Research Laboratory (VDRL) or Rapid Plasma Reagin (RPR) test for syphilis screening.

Special Investigations: (Referral may be necessary)

  1. Rhesus antibodies for Rh-negative mothers.

  2. Random blood sugar test if there is a history or presence of glycosuria (glucose in urine).

  3. Mid-stream urine culture and sensitivity test for suspected urinary tract infection.

  4. High vaginal swab (HVS) for specific infections when indicated.

  5. Enzyme-Linked Immunosorbent Assay (ELISA) test for HIV screening.

  6. Sickling test for sickle cell disease screening.

Other Interventions:

  • Tetanus Toxoid (TT) immunization to complete the recommended schedule for tetanus protection for both mother and newborn.

  • Explain the importance of tetanus immunization to the mother.

Recording, Assessing Findings, and Planning For Management

✔ Record all findings from history, examination, and investigations on the ANC client card and register.
✔ Review all collected findings.
✔ Discuss the plan for the next steps in antenatal care.
✔ If referral is necessary, complete a referral note, provide it to the client, and clearly explain where to go for further management.

Healthcare providers should refer clients to facilities equipped to handle the identified obstetric conditions to minimize delays and transportation costs for the patient and family. With the assistance of family members, arrange prompt transportation. A relative or healthcare worker should accompany the mother when appropriate.

Conducting Follow-Up Visits for Pregnant Women

Purpose of Follow-Up Visits:

  1. Monitor the progress of the pregnancy and the well-being of both mother and fetus.

  2. Identify and manage any new conditions that may arise, such as STIs, HIV risk, pre-eclampsia, anemia, or syphilis.

  3. Provide information and guidance on birth planning, newborn preparation, postpartum care, and family planning options.

  4. Address any concerns or questions the woman may have.

Frequency of Follow-Up Visits:

Routine Schedule:

  1. More frequent visits are needed if the mother has pre-existing or newly identified risk factors.

  2. Every 4 weeks until 30 weeks of gestation.

  3. Then every 2 weeks until 36 weeks of gestation.

  4. Then weekly until delivery.

Increased Frequency for Risk Factors: More frequent follow-up is required for clients with existing or past risk factors such as:

  • Vaginal bleeding in late pregnancy.

  • Uncertainty about gestational dates or late booking for ANC.

  • Past history of pre-eclampsia, premature labor, small or large for gestational age babies.

  • Inadequate weight gain or poor fundal height growth.

  • Excessive weight gain.
