Clinical history taking: pregnant woman with previous LSCS

Start with privacy, introduce yourself, confirm gestational age, and ask about her records, especially the previous operative note/discharge summary.

1. Identification and presenting complaints

  • Name, age, gravida, para, living children
  • Period of gestation and estimated due date
  • Chief complaints:
    • Pain abdomen or scar-site pain
    • Vaginal bleeding
    • Leaking per vaginum
    • Decreased fetal movements
    • Uterine contractions
    • Giddiness, breathlessness, fever, headache, blurring of vision, swelling
Ask specifically about symptoms suggestive of possible scar complication: constant severe abdominal pain, bleeding, contractions, faintness, or reduced fetal movements. These require urgent obstetric assessment.

2. History of present pregnancy

Ask in chronological order:
  • Was the pregnancy planned? Was conception spontaneous or assisted?
  • LMP, dating scan, EDD, and certainty of dates
  • Antenatal registration and number of visits
  • First-trimester screening, anomaly scan, growth scans
  • Fetal movements: when first felt, present/reduced/absent
  • Any complications:
    • Hyperemesis
    • Threatened miscarriage or bleeding
    • Hypertension/pre-eclampsia symptoms
    • Gestational diabetes
    • Anaemia
    • Urinary infection, fever, rash, drug exposure
    • Placenta previa/low-lying placenta
    • Suspected fetal growth restriction, oligohydramnios/polyhydramnios
  • Current medications, iron-folic acid/calcium intake, allergies
  • Blood group and Rh status. If Rh-negative, ask about anti-D prophylaxis.
  • Tetanus/other recommended immunizations
  • Any admission during this pregnancy
Scar-related points
  • Any pain or tenderness over the previous scar?
  • Any bleeding in this pregnancy?
  • What did ultrasound show about placental location? In a woman with prior caesarean birth, a low-lying/anterior placenta needs careful review because of the possibility of placenta accreta spectrum.

3. Detailed history of the previous LSCS

This is the most important section.

A. Indication for LSCS

Ask why the operation was performed:
  • Fetal distress/non-reassuring fetal status
  • Non-progress of labour or failed induction
  • Cephalopelvic disproportion
  • Malpresentation, such as breech or transverse lie
  • Placenta previa/abruption
  • Cord prolapse
  • Severe pre-eclampsia/eclampsia
  • Previous uterine surgery or other maternal/fetal reason
A non-recurrent indication such as breech may favor a future vaginal birth, whereas a previous CS for true cephalopelvic disproportion or recurrent labour dystocia may lower the chance of successful VBAC.

B. Details of the operation

  • Date and place of CS
  • Elective or emergency CS?
  • Gestational age at delivery
  • Type of skin incision
  • Type of uterine incision, if known:
    • Lower-segment transverse incision is generally most favorable for considering VBAC.
    • Classical/upper-segment vertical incision is important because it generally contraindicates VBAC.
  • Any intraoperative complications:
    • Extension of uterine incision
    • Postpartum haemorrhage/blood transfusion
    • Bladder or bowel injury
    • Anaesthesia-related complication
    • ICU admission
  • Was there any postoperative fever, wound infection, wound gaping, resuturing, thrombosis, or prolonged hospital stay?
  • Ask to see the operative note if available.
The previous uterine incision matters more than the visible abdominal skin scar. A prior classical incision or previous uterine rupture needs specialist planning; VBAC is generally not advisable in these settings. RCOG patient guidance

C. Details of the baby

  • Sex, birth weight
  • Live birth/stillbirth/neonatal death
  • Apgar/resuscitation/NICU admission
  • Congenital anomaly, if any
  • Breastfeeding and neonatal course

D. Interpregnancy interval

  • Date of last delivery and interval before current conception
  • Short interpregnancy interval should be noted and discussed with the obstetrician.

4. Previous obstetric history

For every prior pregnancy, ask:
  • Year and outcome
  • Gestational age at outcome
  • Mode of delivery: vaginal/instrumental/CS
  • Indication for operative delivery
  • Birth weight and neonatal outcome
  • Miscarriage, ectopic pregnancy, MTP
  • History of:
    • Postpartum haemorrhage
    • Hypertensive disorder
    • Gestational diabetes
    • Preterm birth
    • Stillbirth/neonatal death
    • Fetal growth restriction
    • Congenital anomalies
    • Thromboembolism
Ask specifically whether she has had a previous vaginal delivery, particularly a vaginal birth after caesarean (VBAC), as this is helpful when counselling about delivery options.

5. Past medical and surgical history

Ask about:
  • Hypertension, diabetes, thyroid disease
  • Cardiac, renal, liver disease
  • Epilepsy, asthma, tuberculosis
  • Blood disorders, including thalassaemia
  • Previous thrombosis or clotting disorder
  • Autoimmune disease
  • Any previous uterine surgery: myomectomy, hysteroscopic septal surgery, curettage/perforation
  • Any other abdominal/pelvic surgery
  • History of blood transfusion

6. Family, personal, and social history

  • Family history of diabetes, hypertension, twins, thromboembolism, congenital anomaly
  • Consanguinity
  • Smoking, alcohol, tobacco or substance use
  • Domestic support, access to hospital and transport
  • Diet, bowel/bladder habits, sleep
  • Occupation and physical workload

7. Delivery planning and counselling history

Ask:
  • Has she been counselled regarding trial of labour after caesarean (TOLAC)/VBAC versus elective repeat CS?
  • Her preference for mode of delivery and reason for preference
  • Does she desire more children? This matters because risks from repeat CS, including adhesions and abnormal placental attachment, tend to rise with multiple caesareans.
  • Does she have a planned place of delivery with immediate facilities for emergency CS, anaesthesia, blood, and newborn care?
For many women with one previous lower-segment transverse CS, VBAC can be considered after individual assessment. The textbook notes that appropriate candidates require attention to the prior scar, reason for CS, obstetric circumstances, and the ability to perform an emergency CS if needed. Textbook of Family Medicine 9e, “Vaginal Birth after Cesarean Section,” lines 728-744. RCOG reports that about three in four women with one previous CS who enter labour spontaneously achieve vaginal birth. RCOG birth-options information
