👶 Complicated Pregnancy
DME 121: Complex Cases
- Multiple Pregnancy (Twins, triplets, complications)
- Amniotic Fluid Disorders (Polyhydramnios, Oligohydramnios)
- IUGR (Causes, diagnosis, management)
- IUFD (Intrauterine Fetal Death, management)
- Prolonged Pregnancy (>42 weeks)
Definition: Carrying more than one fetus (twins, triplets, quadruplets).
Incidence: Twins 1:80 births (1.25%), Triplets 1:8000. Uganda has one of highest twin rates in world - up to 1:20 in some regions!
- Dizygotic (Fraternal): 2 eggs + 2 sperm = 2/3 of twins. Always di-chorionic, di-amniotic (DCDA)
- Monozygotic (Identical): 1 egg splits = 1/3 of twins. Can be:
- DCDA (dichorionic diamniotic) - splits early (days 0-3)
- MCDA (monochorionic diamniotic) - splits days 4-8 - MOST COMMON
- MCMA (monochorionic monoamniotic) - splits days 9-12 - RARE & DANGEROUS
- Conjoined - splits after day 13
Days 0-3 = DCDA (2 sacs, 2 placentas)
Days 4-8 = MCDA (1 placenta, 2 sacs)
Days 9-12 = MCMA (1 sac, 1 placenta)
After day 13 = Conjoined
Maternal age >35 years
Ultrasound use (assisted reproduction)
Large family history of twins
Tall, heavy women (higher BMI)
Induction of ovulation (clomiphene)
Parity (multiparous more likely)
Late maternal age
Ethnicity (African highest risk)
- Clinical: Uterus larger than dates, excessive weight gain, multiple parts on palpation
- Auscultation: 2 distinct fetal heart rates (10+ beats difference, heard in different areas)
- Ultrasound: GOLD STANDARD - confirms number, chorionicity, amnionicity, anomalies
Twin-to-twin transfusion syndrome (TTTS)
Win: PTL/PTD (50% deliver <37 weeks)
IUGR common (30-40%)
Neonatal complications (RDS, low birth weight)
Disproportion (CPD risk)
Ante-partum hemorrhage
Nuchal cord (4x higher risk)
Gestational diabetes & hypertension
Emergency CS common
Remember: PPH risk is 4x higher!
Website: www.nursesrevisionuganda.com
- Early ultrasound: Confirm chorionicity by 12 weeks
- More frequent visits: Every 2 weeks after 24 weeks
- Growth scans: Every 4 weeks (DCDA), every 2 weeks (MCDA)
- Nutrition: Extra protein, iron, folic acid (2x dose!)
- Rest: Advise reduced activity after 28 weeks
- Hospital delivery: MUST deliver at CEmONC facility
- Confirm presentation: Ultrasound on admission
- First twin cephalic: Can attempt vaginal delivery
- First twin non-cephalic: CS recommended
- Monitor both FHRs: Continuous CTG if possible
- IV access: 2 cannulas (PPH risk!)
- After 1st twin: Check 2nd twin's presentation, aim for delivery within 30 minutes
- Active management 3rd stage: Essential for both placentas
- Only in MCDA twins: Connected blood vessels cause imbalance
- Donor twin: Small, oligohydramnios, anemic, stuck
- Recipient twin: Large, polyhydramnios, polycythemia
- Diagnosis: Ultrasound - discordant growth >20%, poly/oligo sequence
- Management: URGENT REFERRAL! Laser ablation at specialized center
Definition: AFI >25 cm or single deepest pocket >8 cm
Incidence: 1% of pregnancies
Pregnancy: Multiple, diabetes (most common!)
Obstruction: GI, CNS anomalies (can't swallow)
Lung masses: Cystic adenomatoid malformation
Your blood group: Rh isoimmunization (hydrops)
- Symptoms: Dyspnea, abdominal pain, edema, uterus >dates
- Complications: PTL, malpresentation, cord prolapse, PPH
- Management: Treat cause, therapeutic amniocentesis, indomethacin (reduces fluid)
Definition: AFI <5 cm or single deepest pocket <2 cm
Incidence: 3-5% of pregnancies
Outflow: PROM, leaking liquor
Limited function: Placental insufficiency, IUGR
Impaired kidneys: Fetal renal agenesis, obstruction
Growth restriction: IUGR most common
Overdue: Post-term pregnancies

Fetus unable to reach its genetic growth potential.
Diagnosis: Estimated fetal weight <10th percentile for gestational age.
Also called: Fetal Growth Restriction (FGR)
- Symmetrical (20-30%): All organs small, head/abdomen proportionate
- Occurs early (<20 weeks), poor prognosis
- Asymmetrical (70-80%): Head normal, abdomen small (brain-sparing effect)
- Occurs late, usually due to placental insufficiency
Infections: Malaria, syphilis, rubella, HIV
Uteroplacental: Preeclampsia, abruption, previa
Genetic: Chromosomal anomalies
Risk factors: Smoking, malnutrition, anemia
&
Multiple pregnancy (discordant)
Absent fetal movements
Low socio-economic status
- Clinical: SFH lagging >3 cm behind gestational age
- Ultrasound:
- EFW <10th percentile
- AC <10th percentile (most sensitive)
- Doppler: Abnormal umbilical artery flow (absent/reversed EDF = severe!)
- Amniotic fluid: Often oligohydramnios
- Mild-moderate:
- Improve nutrition (protein, iron)
- Treat infections (malaria prophylaxis)
- Rest (left lateral position)
- Weekly FHR monitoring
- Growth scans every 2 weeks
- Severe:
- Hospital admission
- Daily monitoring (CTG, kick count)
- Deliver if: Reversed EDF, severe oligohydramnios, non-reassuring CTG
| Type | Delivery Timing | Reason |
|---|---|---|
| Mild IUGR | 37-38 weeks | Avoids stillbirth |
| Moderate IUGR | 34-36 weeks (after steroids) | Better outcome than continuing |
| Severe IUGR | 32-34 weeks (urgent) | Reverse EDF = deliver NOW! |

Fetal death after 28 weeks gestation (or >1000g) before labor.
Also called: Stillbirth. Incidence: 14/1000 in Uganda (higher than global average).
Infections: Malaria (leading cause in Uganda!), syphilis
Umbilical cord: Accidents, knots, prolapse
Fetal: Congenital anomalies, IUGR
Disasters: Abruption, placenta failure
&
Maternal: Hypertension, diabetes, anemia
Antepartum hemorrhage
Rh isoimmunization
- Absent fetal movements for >24 hours
- No FHR on multiple auscultation attempts
- Ultrasound: No cardiac activity (confirmatory)
- Spalding's sign: Overlapping skull bones on X-ray (if ultrasound unavailable)
Counsel both parents together (explain what happened)
Allow time to grieve (don't rush decisions)
Respect cultural/religious wishes (naming, rituals)
Encourage to see/hold baby (if they wish)
&
Deliver within 24-48 hours (infection risk after 48 hrs)
Offer post-mortem (find cause for future pregnancies)
Follow-up appointment (discuss results)
Offer contraception (allow 1 year healing)
Reassure: Most can have healthy babies later
- Cervix favorable: Induce with misoprostol (PGE1)
- Cervix unfavorable: Misoprostol ripening then oxytocin
- Previous CS: Usually CS (uterine rupture risk)
- Dilated cervix (>4cm): ARM + oxytocin
Pregnancy >42 weeks (294 days) from LMP.
Incidence: 5-10% of pregnancies. Risk increases after 40 weeks.
Placental insufficiency (aging placenta)
Oligohydramnios (drastic after 41 weeks)
Stillbirth risk doubles at 42 weeks
Too big baby (macrosomia, >4kg)
Thick meconium (aspiration risk)
Emergency CS (fetal distress)
Respiratory distress (meconium aspiration syndrome)
Maternal trauma (shoulder dystocia)
Meconium aspiration
- Confirm dates: Early ultrasound most accurate
- Monitoring: Twice weekly CTG + amniotic fluid assessment after 40 weeks
- Induction: At 41 weeks (or earlier if any risk factor)
- Cervical ripening with misoprostol
- ARM + oxytocin when favorable
- Deliver by: 42 weeks LATEST!
