Obstetrics

Could you clarify what you want under “Obstetrics”?
  1. Study overview
  2. Specific topic (e.g., preeclampsia, labor stages, PPH)
  3. Clinical management question
  4. Exam prep (MCQs/quick notes)

Everything

Obstetrics is huge, so here is a high-yield complete framework you can use for study and clinical revision.

1) What obstetrics covers

  • Care of mother and fetus from conception to postpartum
  • Normal pregnancy, complications, labor/delivery, and immediate newborn transition

2) Antenatal care (routine)

  • Confirm intrauterine pregnancy, estimate gestational age (LMP + early ultrasound)
  • Baseline risk assessment: medical, surgical, obstetric, social history
  • Screening/labs (varies by guideline/country):
    • CBC, blood group/Rh + antibody screen
    • Infectious screening (HIV, hepatitis B, syphilis, etc.)
    • Urine testing
    • Diabetes screening (24-28 weeks typically)
    • Aneuploidy screening options (first trimester combined, cfDNA, etc.)
  • Supplements: folic acid, iron as needed, calcium depending diet/risk
  • Vaccines in pregnancy per local protocol (e.g., Tdap, influenza)
  • Visit goals: BP, weight trend, fundal height, fetal heart, fetal movement counseling, danger signs

3) Physiologic changes in pregnancy

  • Cardiovascular: increased plasma volume, increased cardiac output, lower SVR
  • Hematologic: physiologic anemia, hypercoagulable state
  • Respiratory: increased minute ventilation, mild respiratory alkalosis
  • Renal: increased GFR
  • Endocrine/metabolic shifts supporting fetal growth

4) Common obstetric complications

Early pregnancy

  • Miscarriage (threatened, inevitable, incomplete, missed)
  • Ectopic pregnancy
  • Hyperemesis gravidarum
  • Gestational trophoblastic disease (less common, high importance)

Mid/late pregnancy

  • Hypertensive disorders:
    • Gestational HTN
    • Preeclampsia/eclampsia
    • HELLP
  • Gestational diabetes mellitus
  • Fetal growth restriction (FGR)
  • Preterm labor and PPROM
  • Antepartum hemorrhage:
    • Placenta previa
    • Placental abruption
  • Multiple gestation complications
  • Cholestasis of pregnancy

5) Fetal assessment

  • Ultrasound:
    • Dating scan
    • Anatomy scan
    • Growth and Doppler when indicated
  • Fetal surveillance:
    • Kick counts
    • NST/CTG
    • Biophysical profile
  • Red flags: reduced fetal movement, abnormal CTG, severe growth restriction, oligohydramnios/polyhydramnios

6) Labor and delivery

Stages of labor

  1. First stage: latent + active cervical dilation
  2. Second stage: full dilation to delivery of fetus
  3. Third stage: delivery of placenta

Intrapartum monitoring

  • Maternal vitals, contractions, cervical progress
  • Fetal heart monitoring (intermittent auscultation or continuous CTG)
  • Partograph can help identify abnormal labor progress

Mode of delivery

  • Vaginal (spontaneous/assisted)
  • Cesarean section indications:
    • Fetal distress not responsive to measures
    • Failed progress/obstructed labor
    • Malpresentation in selected settings
    • Placenta previa major, uterine rupture risk scenarios, etc.

7) Obstetric emergencies (must-know)

  • Postpartum hemorrhage (PPH)
  • Eclampsia
  • Shoulder dystocia
  • Uterine rupture
  • Cord prolapse
  • Amniotic fluid embolism
  • Severe sepsis
  • Key principle: rapid recognition, team response, ABCs, protocol-driven management

8) Postpartum care

  • Monitor bleeding, uterine tone, BP, pain, fever, urinary issues
  • Lactation support, mental health screening, contraception counseling
  • Watch for postpartum preeclampsia, infection, thromboembolism, depression
  • Routine follow-up and chronic risk counseling (e.g., future CVD risk after preeclampsia)

9) High-yield management snapshots

  • Preeclampsia severe features: stabilize mother, seizure prophylaxis (magnesium sulfate), BP control, plan delivery by gestational age/severity
  • PPH: uterine massage + uterotonics + tranexamic acid early + IV access/blood protocol + identify 4 Ts (Tone, Trauma, Tissue, Thrombin)
  • Preterm labor: corticosteroids, tocolysis (selected), magnesium sulfate for fetal neuroprotection (gestation-dependent), GBS prophylaxis as indicated
  • GDM: diet/exercise, glucose monitoring, medication when needed, postpartum glucose re-testing

10) Ethics and communication in obstetrics

  • Maternal autonomy and informed consent are central
  • Balance maternal and fetal risk transparently
  • Respect cultural context, birth preferences, and trauma-informed care
  • Clear escalation and shared decision-making improve outcomes

11) Exam/crash revision list (ultra high yield)

  • Diagnostic criteria: preeclampsia, GDM, labor arrest
  • CTG interpretation and next steps
  • PPH algorithm (first 10 minutes)
  • Ectopic pregnancy diagnosis/management
  • Placenta previa vs abruption differences
  • Induction indications/contraindications
  • VBAC/TOLAC basics and contraindications
  • Rh isoimmunization prevention
  • Postpartum red flags and discharge counseling
If you want, I can now give you:
  1. a one-page obstetrics cheat sheet,
  2. a protocol-style emergency handbook (PPH/eclampsia/shoulder dystocia), or
  3. a 100-question OB exam prep set with answers.
