West Bengal University of Health Sciences

Model Answers - All 10 Questions

Q1. Practical Approach to Evaluation & Management of APH (10 marks)

Definition: Antepartum haemorrhage (APH) is bleeding from the genital tract after 28 weeks of gestation and before delivery of the baby.
Causes (in order of importance):
  • Placenta praevia (~30%)
  • Placental abruption (~30%)
  • Local causes - cervicitis, polyp, carcinoma cervix, vasa praevia
  • Unclassified/unexplained (~40%)
Evaluation - Practical Approach:
History:
  • Onset, amount, colour, associated pain (painless = praevia; painful = abruption)
  • Passage of clots, fetal movements
  • Obstetric history, prior CS, previous APH
Examination:
  • NEVER do PV initially - "hands off the placenta" rule
  • Vitals, pallor, shock assessment
  • Abdominal: uterine tone (woody hard = abruption), lie, presentation, FHR
  • Speculum only (if stable patient) to exclude local causes
Investigations:
  • CBC, blood group & crossmatch, coagulation profile (PT, aPTT, fibrinogen)
  • USG - placental localisation, fetal wellbeing, AFI
  • CTG - fetal surveillance
  • Kleihauer-Betke test (if Rh-negative)
Management:
Stabilisation (ABC):
  • IV access x2, resuscitation with crystalloids/blood
  • O2 supplementation
  • Urinary catheterisation, monitoring UO
Placenta Praevia:
  • If stable + preterm: conservative management with hospitalization, corticosteroids (24-34 wks), tocolytics
  • If term or haemorrhage uncontrolled: caesarean section
  • Type I/II (minor): trial of vaginal delivery possible
Placental Abruption:
  • If mild + viable fetus + no DIC: conservative + monitoring
  • Severe/fetal compromise/term: immediate delivery (CS if rapid delivery not possible vaginally)
  • Correct coagulopathy (FFP, cryoprecipitate, platelets)
  • Watch for PPH after delivery
Vasa Praevia:
  • Immediate CS on diagnosis when bleeding is associated with ruptured membranes

Q2. USG Evaluation of Fetal Hydronephrosis & Outline Management (10 marks)

Definition: Fetal hydronephrosis (FH) is dilatation of the renal pelvis detected on antenatal USG. Defined as Anterior-Posterior Renal Pelvic Diameter (APRPD) ≥4 mm in 2nd trimester, ≥7 mm in 3rd trimester.
USG Evaluation:
Parameters to assess:
  1. APRPD - mild (<10 mm), moderate (10-15 mm), severe (>15 mm)
  2. Calyceal dilatation - peripheral calyces involved = more significant
  3. Parenchymal thickness - thinning indicates obstruction severity
  4. Echogenicity - increased echogenicity suggests dysplasia
  5. Contralateral kidney - normal? compensatory hypertrophy?
  6. Ureter - hydroureter suggests VUJ or VUR
  7. Bladder - thick wall (posterior urethral valves), "keyhole sign" in PUV
  8. Amniotic fluid - oligohydramnios indicates bilateral severe disease
  9. Adrenal glands - distinguish from multicystic dysplastic kidney
Grading (SFU - Society for Fetal Urology):
  • Grade 0: Normal
  • Grade I: Mild renal pelvis splitting
  • Grade II: Pelvis dilated, no calyceal dilatation
  • Grade III: Pelvis + calyces dilated, normal parenchyma
  • Grade IV: Parenchymal thinning present
Causes to identify:
  • UPJ (Ureteropelvic Junction) obstruction - most common
  • VUJ (Vesicoureteric Junction) obstruction
  • VUR (Vesicoureteric Reflux)
  • Posterior Urethral Valves (PUV) - bilateral, keyhole sign
  • Multicystic dysplastic kidney (MCDK)
  • Duplex system, ureterocele, ectopic ureter
Management:
Antenatal:
  • Serial USG every 4-6 weeks
  • Mild (APRPD <10 mm) - observe, most resolve spontaneously
  • Fetal vesicocentesis if severe bilateral disease with oligohydramnios to assess fetal renal function (Na+, Cl-, osmolality in fetal urine)
  • Vesico-amniotic shunting - in select cases of bladder outlet obstruction with good renal function
  • Karyotyping offered (association with aneuploidy)
Postnatal:
  • APRPD <10 mm: postnatal USG at 4-6 weeks, MCUG, DMSA if indicated
  • APRPD >10 mm/SFU grade III-IV: early postnatal USG, prophylactic antibiotics, MCUG, DTPA/MAG3 renogram
  • Surgical: Pyeloplasty for UPJ obstruction, ureteroneocystostomy, valve ablation for PUV

Q3. Fetal ECG as Antepartum Fetal Surveillance (10 marks)

Introduction: Fetal ECG (FECG) analysis is a newer modality for antepartum and intrapartum fetal surveillance, complementing conventional CTG.
Basis:
  • Fetal ECG can be extracted from maternal abdominal surface electrodes (non-invasive) or directly from fetal scalp electrode (intrapartum)
  • Provides PR interval, QRS morphology, ST segment, and T/QRS ratio
Parameters Evaluated:
1. ST Analysis (STAN - ST Analysis):
  • T/QRS ratio - reflects fetal myocardial response to hypoxia
  • Hypoxic stress activates anaerobic glycogenolysis → myocardial glycogen mobilised → ST elevation and increased T/QRS ratio
  • Biphasic ST - indicates myocardial depression (more dangerous than T elevation)
  • Used primarily intrapartum in STAN monitors (combined CTG + FECG)
2. PR Interval:
  • Reflects AV conduction; prolonged PR with late decelerations suggests vagal overactivation from hypoxia
3. QRS Complex:
  • Width and morphology; ventricular conduction changes in severe acidosis
Clinical Application:
Intrapartum STAN:
  • Combined CTG + STAN reduces fetal metabolic acidosis and need for fetal blood sampling
  • Significant T/QRS rise (>0.15) with abnormal CTG = delivery indicated
  • Meta-analyses show reduction in operative delivery for fetal distress and reduction in neonatal metabolic acidosis
Antepartum FECG (Non-invasive):
  • Signal extracted from maternal abdominal ECG electrodes
  • Currently more research-based; challenges include maternal signal interference
  • Useful for detecting fetal arrhythmias antenatally (SVT, complete heart block)
  • PR interval prolongation on fetal MCG/FECG - early marker in anti-Ro/anti-La antibody positive mothers (neonatal lupus)
Limitations:
  • Technical difficulty in signal extraction (maternal ECG dominant)
  • Low signal-to-noise ratio particularly in obese patients
  • Not yet standard for routine antepartum surveillance
  • More validated for intrapartum use
Conclusion: While fetal ECG (particularly STAN) is well-established intrapartum, its antepartum role as a surveillance tool is evolving, with most evidence for arrhythmia detection rather than routine hypoxia surveillance.

Q4. Peripartum Cardiomyopathy (3+2+3+2 = 10 marks)

A. Common Presenting Features (3 marks):
PPCM is defined as heart failure developing in the last month of pregnancy or within 5 months of delivery, in the absence of prior heart disease, with LV EF <45% and no identifiable cause.
Symptoms mimic normal pregnancy changes, hence often delayed:
  • Dyspnoea (most common) - initially exertional, then at rest
  • Orthopnoea and paroxysmal nocturnal dyspnoea
  • Pedal oedema (often dismissed as physiological)
  • Fatigue, palpitations, decreased exercise tolerance
  • Cough (pulmonary oedema)
  • Advanced: chest pain, syncope, embolic events (stroke, PE)
B. Diagnostic Evaluation (2 marks):
  • ECG: Non-specific ST-T changes, left bundle branch block, arrhythmias
  • CXR: Cardiomegaly, pulmonary venous congestion, pleural effusions
  • Echocardiography: LV EF <45%, global hypokinesia, LV dilatation - GOLD STANDARD
  • BNP/NT-proBNP: Markedly elevated, confirms heart failure
  • MRI: Inflammatory pattern - useful when echo is inconclusive
  • Exclude: Hypertensive heart disease, pre-existing cardiomyopathy, myocarditis, valvular disease
C. Risk Factors (3 marks):
  • Maternal age >30 years
  • African-American race (4x higher incidence)
  • Multiparity and twin/multiple gestation
  • Hypertension and preeclampsia (~25% of PPCM cases have preeclampsia)
  • Prolonged tocolytic therapy (especially beta-agonists)
  • Cocaine use
  • Genetic predisposition - TTN gene variants (titin mutations); 15% carry truncating variants
  • Nutritional deficiency (selenium, selenium)
  • Viral myocarditis (enterovirus, parvovirus B19)
  • Prolactin-mediated toxicity (16kDa prolactin fragment - oxidative stress-induced cleavage)
D. Treatment (2 marks):
Antepartum (if occurs before delivery):
  • Avoid ACE inhibitors/ARBs (teratogenic) - use hydralazine + nitrates instead
  • Beta-blockers (metoprolol) - safe in pregnancy
  • Diuretics (furosemide) - cautious use
  • Anticoagulation with LMWH if EF <35% (prothrombotic state)
  • Delivery planning with multidisciplinary team
Postpartum:
  • ACE inhibitor (enalapril) + beta-blocker + diuretic = standard HF therapy
  • Bromocriptine (dopamine agonist) - inhibits prolactin, shown in small studies to improve EF - still controversial
  • Discontinue breastfeeding if bromocriptine used
  • ICD if persistent EF <35% after 3-6 months
  • Heart transplantation in refractory cases
  • Counselling: recurrence risk ~20% if EF normalised, ~40% if persistent LV dysfunction (mortality 19% in latter group)

Q5. Background & Rationale of Preconception Care (10 marks)

Definition: Preconception care (PCC) encompasses a set of biomedical, behavioural, and social health interventions for women and couples before conception to improve pregnancy outcomes.
Background:
The concept recognises that many factors determining pregnancy outcome are established before the first antenatal visit (often 8-12 weeks). By this time, organogenesis is largely complete, making primary prevention impossible without preconception intervention.
Rationale:
Medical conditions requiring optimisation:
  • Diabetes mellitus - HbA1c optimisation reduces NTDs, cardiac defects, miscarriage, macrosomia; start folic acid 5 mg/day
  • Epilepsy - change to safer AEDs (lamotrigine preferred); avoid valproate
  • Thyroid disease - euthyroid state before conception reduces miscarriage, intellectual disability
  • Hypertension - switch teratogenic agents (ACEi, ARBs) to methyldopa/labetalol
  • SLE/autoimmune - assess disease quiescence; continue hydroxychloroquine
  • Cardiac disease - classify risk (mWHO risk classification); counsel on maternal/fetal risk
  • Renal disease - creatinine, proteinuria assessment; optimise BP
  • Obesity - weight loss, bariatric surgery timing (12-18 month gap before conception)
  • Depression/anxiety - review psychotropic medications
Nutritional interventions:
  • Folic acid 0.4 mg/day (5 mg if high risk) - reduces NTD by 70%
  • Iodine supplementation in deficient populations
  • Iron supplementation in anaemic women
  • Stop alcohol, smoking, illicit drugs
Infectious disease screening:
  • Rubella immunity (MMR if non-immune - wait 1 month before conception)
  • Varicella immunity
  • Hepatitis B, C, HIV testing
  • STI screening and treatment
  • Toxoplasma, CMV counselling
Genetic counselling:
  • Family history of chromosomal/single-gene disorders
  • Carrier screening (thalassaemia, sickle cell, CF, SMA)
  • Consanguineous couples - specific counselling
Reproductive history review:
  • Recurrent miscarriages - thrombophilia screen, APA, uterine anomaly
  • Previous preterm birth - progesterone prophylaxis planning
  • Previous CS - discuss VBAC or elective CS
Social factors:
  • Domestic violence screening
  • Occupational hazard review
  • Stress and mental wellbeing
Outcome benefits documented:
  • Reduction in NTDs, congenital heart defects, diabetic embryopathy
  • Lower rates of preterm birth and low birth weight
  • Improved maternal health outcomes
  • Cost-effective (prevents costly neonatal intensive care admissions)
WHO recommends preconception care as an integral part of women's health services, not a separate vertical programme.

Q6. Management of Pregnancy in Recipient After Kidney Transplant (10 marks)

Background: ~1:50 women of reproductive age with kidney transplant can conceive. Fertility returns within months of transplantation. Careful counselling and multidisciplinary management is essential.
Prerequisites Before Conception:
  • Wait ≥2 years post-transplant (stable graft function, reduced immunosuppression)
  • Serum creatinine <1.5 mg/dL (ideally <1.0 mg/dL)
  • Proteinuria <500 mg/24 hours
  • BP well-controlled (<130/80 mmHg)
  • No recent rejection episode (1 year minimum)
  • Immunosuppression on stable maintenance regimen
  • No active infections (CMV, BK virus cleared)
Immunosuppression Management:
  • Safe in pregnancy: Azathioprine, Ciclosporin, Tacrolimus, Prednisolone
  • Contraindicated: Mycophenolate mofetil (MMF) - teratogenic (VACTERL-like anomalies); stop 6 weeks before conception
  • Convert MMF to azathioprine before conception
  • Target immunosuppression levels carefully - avoid under-immunosuppression (rejection risk) and over-immunosuppression (infection)
Antenatal Complications (increased risk):
  • Hypertension and pre-eclampsia (~30%)
  • Gestational diabetes (steroids, CNI effect)
  • Acute rejection episodes (~5%)
  • Opportunistic infections (CMV reactivation, UTI, pyelonephritis)
  • Anaemia (erythropoietin may be needed)
  • Graft dysfunction/deterioration
Monitoring:
  • Monthly renal function tests (creatinine, proteinuria, eGFR)
  • Drug levels (cyclosporin/tacrolimus trough levels) - pregnancy alters pharmacokinetics
  • Graft ultrasound with Doppler at each trimester
  • Serial fetal growth scans (4-weekly from 26 weeks) - IUGR risk
  • Urine C&S monthly (asymptomatic bacteriuria should be treated)
  • BP monitoring twice weekly
Fetal Surveillance:
  • UADV, biophysical profile from 32 weeks
  • CTG from 36 weeks
Mode & Timing of Delivery:
  • Aim for vaginal delivery if no obstetric contraindication
  • Transplanted kidney in iliac fossa does not obstruct labour (pelvic anatomy preserved)
  • Deliver at 37-38 weeks or earlier if graft deterioration/PE
  • Prophylactic antibiotics at delivery
  • Continue immunosuppression peripartum
Neonatal Considerations:
  • Preterm birth common
  • Neonatal immunosuppression effect (lymphopenia - transient)
  • Avoid live vaccines in first 3-6 months
  • Breastfeeding: generally discouraged (MMF/tacrolimus levels in breast milk); azathioprine may be acceptable
Long-term: Pregnancy generally does not adversely affect graft survival if patient is well-selected. 5-year graft survival similar to non-pregnant transplant recipients.

Q7. Etiology & Diagnosis of Non-Immune Hydrops Fetalis (10 marks)

Definition: Non-immune hydrops fetalis (NIHF) is the accumulation of excess fluid in ≥2 fetal body compartments (ascites, pleural effusion, pericardial effusion, skin oedema >5 mm) in the absence of red cell alloimmunisation.
Etiology (approximately 85% of all hydrops is now non-immune):
Cardiovascular (25-30%) - most common:
  • Structural: hypoplastic left heart, AV canal defects, pulmonary atresia
  • Arrhythmias: SVT (most common treatable cause), complete heart block (anti-Ro/La)
  • Cardiomyopathy
  • High-output failure: AV malformations, sacrococcygeal teratoma
Chromosomal (10-15%):
  • Turner syndrome (45X) - most common chromosomal cause
  • Trisomy 21, 18, 13
  • Triploidy
Haematological (10%):
  • Alpha-thalassaemia major (Hb Bart's) - most common in Southeast Asia
  • Fetal anaemia - parvovirus B19 (B19 infects erythroid precursors)
  • Fetomaternal haemorrhage
Structural abnormalities (15%):
  • CCAM (Congenital Cystic Adenomatoid Malformation)/CPAM
  • Diaphragmatic hernia - mediastinal shift
  • Bronchopulmonary sequestration
  • Hepatic haemangioma
Infectious (5-10%):
  • Parvovirus B19 (aplastic anaemia)
  • CMV, Toxoplasma, Syphilis, Rubella
  • Leptospirosis, Listeria
Placental/umbilical:
  • Twin-to-twin transfusion syndrome (TTTS) - recipient twin
  • Umbilical vein thrombosis, chorioangioma
Metabolic/storage disorders (rare):
  • Gaucher, Niemann-Pick, Mucopolysaccharidoses
  • Lysosomal storage disorders
Idiopathic: 15-25% (no cause found despite full investigation)
Diagnosis:
Sonographic evaluation:
  • Define sites and severity of fluid accumulation
  • Detailed structural survey (cardiac, lungs, abdomen)
  • Placental thickness, cord, AFI
  • Doppler: MCA PSV >1.5 MOM (fetal anaemia), UA, DV
  • 3D echocardiography for cardiac causes
Maternal investigations:
  • Blood group and Coombs test (exclude immune)
  • CBC, peripheral smear
  • Kleihauer-Betke test (fetomaternal haemorrhage)
  • TORCH serology (CMV, toxo, rubella, HSV, syphilis)
  • Parvovirus B19 IgM/IgG (PCR if needed)
  • Haemoglobin electrophoresis (alpha-thal carrier)
  • Anti-Ro, anti-La antibodies (complete heart block)
  • Glucose-6-PD
Invasive testing:
  • Amniocentesis - karyotype (array CGH preferred), microarray, metabolic studies, infection PCR
  • Cordocentesis - fetal blood: CBC, Hb, blood group, karyotype, PCR, enzyme assay
  • Pleural/pericardial tap - fluid analysis + culture
Management Overview:
  • Depends on etiology
  • Treatable causes: Fetal SVT (digoxin/flecainide to mother), fetal anaemia (intrauterine transfusion), TTTS (fetoscopic laser)
  • Prognosis generally poor - perinatal mortality 50-98% depending on cause
  • Genetic counselling for recurrence

Q8. Management of Pregnant Woman with Congenital Cyanotic Heart Disease (10 marks)

Background: Congenital cyanotic heart disease (CCHD) includes Tetralogy of Fallot (post-repair and unrepaired), Eisenmenger syndrome, single ventricle physiology, tricuspid atresia, and pulmonary atresia.
Preconception Counselling:
  • Classify by mWHO risk classification (I-IV)
  • Eisenmenger syndrome, unrepaired cyanotic CHD, severe pulmonary hypertension = mWHO Class IV - pregnancy contraindicated (maternal mortality 25-50%)
  • Corrected ToF with good ventricular function = mWHO Class II-III
  • Discuss risks: maternal cardiac decompensation, arrhythmias, thromboembolism, death
  • Fetal risks: IUGR, prematurity, CHD recurrence (5-10% offspring)
Physiological Challenges:
  • Increased cardiac output in pregnancy (up to 50% increase by 28 weeks) is poorly tolerated
  • Right-to-left shunt worsens with decreased SVR (vasodilation in pregnancy)
  • Hyperviscosity from polycythaemia + hypercoagulable state of pregnancy = thrombosis risk
  • Hypoxaemia causes fetal growth restriction and preterm labour
  • Labour and delivery: Valsalva, haemorrhage, aortocaval compression all critical
Antenatal Management (Multidisciplinary - Cardiologist + MFM):
Monitoring:
  • Monthly cardiac review minimum; echocardiography each trimester
  • Oxygen saturation monitoring
  • Serial fetal growth scans (4-weekly from 24 weeks)
  • Fetal echo at 18-20 weeks (CHD recurrence)
Medical:
  • Continue anti-arrhythmics if required (assess teratogenicity)
  • Beta-blockers for tachyarrhythmias (safe)
  • Anticoagulation: Polycythaemia (haematocrit >65%) or prior thromboembolism - use LMWH
  • Avoid ACEi/ARBs, ERAs (endothelin receptor antagonists - teratogenic)
  • Iron - cautious (polycythaemia may worsen)
  • Supplemental O2 if resting SpO2 <85%
  • Venesection if haematocrit >65% with symptoms
Specific - Eisenmenger Syndrome:
  • Maternal mortality 25-50%; termination strongly advised
  • If continuation: IV prostacyclin, inhaled iloprost, sildenafil (all Class X in pregnancy - risk vs benefit)
  • Hospitalisation from 20 weeks; avoid dehydration
Intrapartum Management:
  • Planned delivery in tertiary cardiac centre
  • Avoid prolonged labour
  • Vaginal delivery preferred in stable cases (less haemorrhage, less anaesthetic risk)
  • Epidural analgesia (reduces SVR - use cautiously in right-to-left shunt; slow titration)
  • Avoid Syntocinon bolus (hypotension)
  • Continuous monitoring: ECG, SpO2, arterial line ± CVP
  • Early active stage II (avoid Valsalva); instrumental delivery if needed
  • CS reserved for obstetric indications or severe decompensation
  • Avoid aortocaval compression (left lateral tilt)
Postpartum:
  • High-risk period: first 24-48 hours (autotransfusion, fluid shifts)
  • Diuretics if pulmonary oedema
  • Continue anticoagulation 6 weeks minimum
  • Contraception: oestrogen-containing methods contraindicated (POP, progesterone implant, LNG-IUS preferred)

Q9. Diagnosis & Management of Bicornuate Uterus with Reproductive Outcome (10 marks)

Definition: Bicornuate uterus is a Müllerian duct fusion defect (Class IV, AFS classification) characterised by two uterine horns with a single cervix (bicornuate unicollis) or two cervices (bicornuate bicollis), resulting from incomplete fusion of the Müllerian ducts at the fundal level.
Embryology: Müllerian ducts normally fuse at ~10 weeks gestation. Bicornuate uterus results from partial non-fusion at the fundal level. The fundal indentation depth determines the degree of deformity (complete vs partial).
Diagnosis:
Clinical:
  • Often incidental; may present with recurrent miscarriage, preterm labour, malpresentation
Imaging:
  • 2D USG: Two separate horns, echogenic endometrium in each, V-shaped external fundal contour; limited sensitivity
  • 3D USG (transvaginal): Best non-invasive method; shows external fundal notch >1 cm (vs septate uterus where fundal contour is convex/flat); interhorn angle >105°
  • MRI (Gold Standard): Differentiates bicornuate from septate uterus precisely; shows fundal indentation ≥1 cm, concave external contour, two endometrial cavities
  • HSG (Hysterosalpingogram): Shows two divergent cornual horns (>105° angle), Y-shaped configuration; cannot assess external contour (cannot distinguish from septate)
  • Diagnostic laparoscopy + hysteroscopy: Definitive - fundal notch visible on laparoscopy; two separate cavities on hysteroscopy
Differentiation from Septate Uterus (critical):
FeatureBicornuateSeptate
External fundal contourConcave (notch >1 cm)Convex/flat
MRI/3D USGTwo separate hornsSingle uterine body
ManagementSurgery rarely neededHysteroscopic septal resection
Reproductive Outcomes:
  • Miscarriage rate: 25-47% (vs ~15% general population)
  • Preterm delivery rate: ~15-25%
  • Malpresentation: 40-50% (transverse, breech) - highest among Müllerian anomalies
  • Live birth rate: 50-60% without intervention
  • Preterm premature rupture of membranes: Increased
Management:
Conservative:
  • Mild cases with successful pregnancies: no intervention
  • Optimise cervical competence (cervical length monitoring)
  • Progesterone supplementation for recurrent miscarriage/short cervix
  • Cervical cerclage if cervical incompetence
Surgical - Strassman Metroplasty:
  • Indication: ≥3 consecutive pregnancy losses attributed to the uterine anomaly (after excluding other causes)
  • Open procedure via laparotomy (or laparoscopic)
  • Technique: Incise the fundus between the two horns, excise the medial walls, reunite the two horns into a single cavity
  • Post-op: 6-month interval before conception; delivery by elective CS (risk of uterine rupture)
  • Outcomes: Live birth rate improves from ~30% to ~80% post-Strassman in selected patients
Antenatal surveillance after diagnosis:
  • Regular cervical length assessment (14-24 weeks)
  • Serial growth scans
  • Vigilance for preterm labour
  • Mode of delivery: CS for malpresentation (very common)

Q10. Short Notes

a) Cord Prolapse (5 marks)

Definition: Descent of the umbilical cord through the cervix alongside (occult) or beyond (overt) the presenting part after membrane rupture.
Incidence: 0.1-0.6% of deliveries
Predisposing Factors:
  • Malpresentation: footling breech, transverse lie, oblique lie
  • Prematurity, low birth weight, multiparity
  • High presenting part: unengaged head at rupture of membranes
  • Polyhydramnios
  • Artificial rupture of membranes with unengaged head
  • Cord abnormalities: long cord, velamentous insertion
  • Multiparity, multiple gestation, unengaged presenting part
Diagnosis:
  • Palpation of cord in vagina or at introitus
  • Acute variable decelerations or prolonged bradycardia on CTG after membrane rupture
  • Occult: suspected from CTG changes; identified on VE
Management:
Immediate:
  1. Call for help (emergency)
  2. Relieve cord compression: Push presenting part up manually per vaginam (hand stays in until delivery)
  3. Knee-chest position or Trendelenburg/exaggerated Sim's position
  4. Fill bladder with 500-700 mL saline (elevates presenting part, reduces compression)
  5. Keep cord warm and moist (wrap in moist towel if prolapsed)
  6. DO NOT replace cord in uterus (vasospasm risk)
  7. O2 to mother
  8. Continuous CTG
Delivery:
  • Immediate CS (category 1) if fetus alive and viable
  • Ventouse/forceps if fully dilated and delivery imminent
  • Maternal position maintained until delivery
Outcome: Perinatal mortality 5-10% if managed promptly in hospital; much higher in community.

b) Shoulder Dystocia (5 marks)

Definition: Shoulder dystocia occurs when the fetal anterior shoulder impacts behind the maternal pubic symphysis after delivery of the fetal head, requiring additional obstetric manoeuvres.
Incidence: 0.6-3% of vaginal deliveries
Risk Factors:
  • Antenatal: Macrosomia (EFW >4 kg), diabetes, obesity, post-dates, previous shoulder dystocia
  • Intrapartum: Prolonged first stage, prolonged second stage, oxytocin augmentation, instrumental delivery (especially mid-cavity)
  • Note: 50% occur without any identifiable risk factor
Recognition:
  • "Turtle sign" - head delivers but then retracts back against perineum
  • Failure of restitution and external rotation
  • Failure of shoulders to deliver with normal traction
Management - HELPERR Mnemonic:
  • H - Call for Help (senior obstetrician, paediatrician, anaesthetist, midwives)
  • E - Evaluate for Episiotomy (gives more room for manoeuvres; does not release bony impaction but aids access)
  • L - Legs (McRoberts manoeuvre) - hyperflex maternal thighs on abdomen; flattens lumbar lordosis, rotates pubic symphysis superiorly; most effective single manoeuvre (resolves 40%)
  • P - Suprapubic Pressure (Mazzanti/Rubin) - downward and lateral pressure on posterior aspect of anterior shoulder to dislodge it; used with McRoberts
  • E - Enter (internal rotational manoeuvres):
    • Rubin II: Pressure on posterior aspect of anterior shoulder to rotate anteriorly
    • Woods screw: Pressure on anterior aspect of posterior shoulder to rotate
    • Reverse Woods (Rubin): Combined rotation
  • R - Remove posterior arm - sweep posterior arm across fetal chest and deliver it first; reduces shoulder width
  • R - Roll (Gaskin manoeuvre) - all-fours position; gravity assists posterior shoulder delivery
Last resort manoeuvres:
  • Zavanelli manoeuvre (cephalic replacement + emergency CS)
  • Deliberate clavicle fracture
  • Symphysiotomy
Documentation: Record exact timings, manoeuvres used, staff present, cord gases, Apgar scores. Neonatal risks: brachial plexus injury (Erb's palsy), fractures, hypoxic-ischaemic encephalopathy.
