DC Dutta's textbook is not in the library. I'll use the available obstetrics resources (Creasy & Resnik's Maternal-Fetal Medicine, Berek & Novak's) and my own knowledge to compose a thorough short note in DC Dutta's style. Let me read the relevant sections.

I now have enough material. DC Dutta's textbook is not in the library, but I have comprehensive content from Creasy & Resnik's Maternal-Fetal Medicine and my knowledge of DC Dutta's style. Let me now compose a thorough short note in the style of DC Dutta's "Textbook of Obstetrics."
STILLBIRTH
(Short Note - DC Dutta Style)
Definition
Stillbirth (Intrauterine fetal death, IUFD) is defined as the birth of a fetus showing no signs of life after complete expulsion or extraction from the mother, at or after 28 weeks of gestation (WHO/DC Dutta definition used in India and most developing countries). In the UK, the threshold is 24 weeks; in the USA, 20 weeks.
Stillbirth rate = Number of stillbirths per 1000 total births (live + still).
Classification
1. By Timing
| Type | Gestation |
|---|---|
| Early stillbirth | 20-27 weeks |
| Late stillbirth | 28-36 weeks |
| Term stillbirth | ≥37 weeks |
2. By Timing Relative to Labor
- Antepartum (macerated): Fetus dies before onset of labor - most common (~85%)
- Intrapartum (fresh): Fetus dies during labor - associated with acute hypoxia
3. By Appearance
- Fresh stillbirth: Fetus intact, no maceration; died shortly before delivery
- Macerated stillbirth: Skin peeling, discoloration, collapsed skull (Spalding's sign on X-ray), overlapping bones; died ≥12 hours before delivery
Etiology (Causes)
Fetal Causes (~25-40%)
- Congenital anomalies (chromosomal - trisomy 13, 18, 21; structural defects)
- Fetal growth restriction (FGR)
- Multiple pregnancy (twin-to-twin transfusion syndrome)
- Hydrops fetalis (immune or non-immune)
- Cord accidents: tight nuchal cord, true knot, cord prolapse, cord compression
Placental Causes (~25%)
- Placental abruption (most common acute cause)
- Placenta previa with massive haemorrhage
- Placental insufficiency
- Velamentous cord insertion, vasa previa
Maternal Causes (~10-15%)
- Hypertensive disorders (preeclampsia, eclampsia, chronic hypertension)
- Diabetes mellitus (poorly controlled; DKA)
- Antiphospholipid syndrome (APS)
- Infections: malaria, syphilis, TORCH infections, Group B Streptococcus, Listeria
- Anaemia (severe, Hb <7 g/dL)
- Cholestasis of pregnancy (intrahepatic)
- Rh incompatibility / isoimmunization
- Renal disease, SLE, thyroid disorders
- Trauma, uterine rupture
- Prolonged pregnancy (post-term, >42 weeks)
Unknown (~25-30%)
- "Unexplained" even after thorough workup - a significant proportion
Diagnosis
Clinical Features
- Cessation of fetal movements - most common presenting symptom
- Absence of fetal heart sounds on auscultation / Doppler
- Uterus smaller than dates in macerated cases
- Absence of fetal kicks confirmed by mother
Investigations
1. Ultrasound (gold standard)
- Absence of cardiac activity
- No fetal movements
- Spalding's sign: Overlapping of skull bones due to liquefaction of brain (on X-ray or US)
- Robert's sign: Gas in fetal vessels (X-ray)
- Maceration features
2. CTG / Electronic Fetal Monitoring: Absent trace
3. Maternal Blood Tests:
- Kleihauer-Betke test (fetomaternal hemorrhage)
- Blood group + antibody screen (Rh isoimmunisation)
- TORCH serology
- Thrombophilia screen (lupus anticoagulant, anticardiolipin antibodies, Factor V Leiden)
- Fasting blood glucose / HbA1c (diabetes)
- LFTs, bile acids (obstetric cholestasis)
- CBC, coagulation profile (DIC screen)
- Thyroid function tests
4. Post-delivery:
- Autopsy (perinatal)
- Placental histopathology
- Karyotype (from fetal skin, placenta, amniotic fluid)
- Culture (placenta, membranes)
- X-ray of fetus (skeletal dysplasia, Roberts' sign, Spalding's sign)
Complications to the Mother
- Disseminated Intravascular Coagulation (DIC): Occurs if dead fetus is retained >4 weeks (especially with abruption). Thromboplastin released from necrotic tissue activates coagulation cascade.
- Psychological morbidity: Grief, depression, anxiety, PTSD
- Infection: Chorioamnionitis (if prolonged retention)
- Lactation suppression may be required
Management
Immediate
- Confirm diagnosis with ultrasound
- Inform parents sensitively; offer bereavement support
- Baseline investigations: CBC, coagulation profile, blood group
- DIC screen every 2 weeks if delivery deferred
Delivery
- Vaginal delivery is preferred in most cases
- Induction of labor:
- < 28 weeks: Misoprostol (most effective, regardless of Bishop score)
- ≥ 28 weeks: Oxytocin infusion ± cervical ripening (prostaglandins, Foley catheter)
- Caesarean section: Avoided unless clear maternal indication; discussed if prior uterine scar
Post-delivery
- Offer parents opportunity to see and hold the baby
- Photographs, foot/handprints (keepsakes)
- Suppression of lactation (cabergoline/bromocriptine)
- Placenta and fetus for autopsy + histopathology
- Bereavement counseling; support groups
Stillbirth Rate in India
- India accounts for a large share of global stillbirths
- National Stillbirth Rate ~13-15 per 1000 total births
- Major contributors: infections, anemia, hypertension, lack of skilled attendance
Prevention
| Strategy | Rationale |
|---|---|
| Awareness of decreased fetal movements | Prompts early evaluation |
| Kick counts (Cardiff method, Sadovsky method) | Detect fetal compromise early |
| Antenatal care: regular BP, urine, FHR | Detect preeclampsia, growth restriction |
| Control of diabetes, hypertension | Reduce placental insufficiency |
| Anti-D prophylaxis | Prevent Rh isoimmunization |
| Low-dose aspirin in high-risk cases | Reduce FGR, preeclampsia |
| Cervical cerclage, progesterone | Reduce preterm stillbirths |
| Induction at 41-42 weeks in post-term | Reduce term/post-term stillbirths |
Recurrence Risk
- Previous stillbirth increases risk of recurrence 2-10 fold (depends on cause)
- Unexplained stillbirth: ~1-2% recurrence risk
- Subsequent pregnancies should have enhanced monitoring: serial growth scans, antenatal surveillance from 32 weeks, Doppler studies
