K.M.S.K. GMC Chandrapur - OB/GYN 5th Internal Assessment Answers
Q.1 SAQ ANSWERS
SAQ 1 - Contraception: Male and Female Barrier Methods
Definition: Barrier methods physically prevent the sperm from reaching the ovum, thereby preventing fertilization.
Female Barrier Methods
1. Female Condom (Femidom)
- Made of polyurethane or nitrile; pre-lubricated
- Inserted into the vagina before intercourse, covering cervix and vaginal walls
- One end is closed (intravaginal ring), other end is open and covers the vulva
- Failure rate: ~5% (perfect use), ~21% (typical use)
- Advantages: STI protection, can be inserted before sex, female-controlled
- Disadvantages: Less aesthetically acceptable, higher cost
2. Diaphragm
- Dome-shaped rubber/silicone cup; inserted vaginally before sex to cover the cervix
- Always used with spermicide for added efficacy
- Must be left in place for 6 hours after last intercourse; must be fitted by a provider
- Failure rate: ~6% (perfect use), ~12% (typical use)
- Does not protect against STIs
3. Cervical Cap (FemCap)
- Smaller silicone cap fitting directly over cervix
- Used with spermicide; efficacy varies with parity
- Parous women: higher failure rate (~26% typical use)
- Nulliparous women: ~9% typical use
4. Contraceptive Sponge
- Polyurethane sponge impregnated with nonoxynol-9 (spermicide)
- Inserted before sex; blocks cervical os, releases spermicide, absorbs semen
- Left in for 6 hours post-coitus; single use only
- Failure rate: ~9-12% (nulliparous), ~20-24% (parous)
5. Spermicide (alone)
- Chemical agents (nonoxynol-9): creams, gels, foams, suppositories
- Destroy sperm cell membranes
- High failure rate (~28%) when used alone; generally used with other barriers
Male Barrier Methods
1. Male Condom
- Most widely used barrier; made of latex, polyurethane, or polyisoprene
- Rolled onto erect penis before intercourse
- Failure rate: ~2% (perfect use), ~13-18% (typical use)
- Only contraceptive method providing dual protection: pregnancy AND STIs (including HIV)
- Advantages: Widely available, cheap, no hormonal side effects, OTC
- Disadvantages: Requires cooperation, may reduce sensitivity, can tear/slip
- Contraindicated: Latex allergy (use polyurethane)
2. Male Diaphragm / Sperm Shield (experimental)
- Not in widespread clinical use
SAQ 2 - Carbetocin
Definition: Carbetocin is a long-acting synthetic oxytocin analogue used for prevention of postpartum hemorrhage (PPH).
Structure: It is a synthetic octapeptide with a similar structure to oxytocin but with a carbetocin side chain attached, making it more resistant to enzymatic degradation.
Pharmacokinetics:
- Onset of action: ~2 minutes IV, ~7 minutes IM
- Half-life: ~40 minutes (compared to oxytocin: ~4-10 minutes)
- Duration of uterotonic effect: ~1 hour IV, ~2 hours IM
- Route: IV (100 mcg slow bolus) or IM (100 mcg)
Mechanism of Action:
- Binds to oxytocin receptors in myometrium
- Produces sustained tetanic uterine contractions
- Reduces uterine relaxation
Indications:
- Prevention of uterine atony and PPH following:
- Elective or emergency caesarean section
- Vaginal delivery (in high-risk cases)
- Single-dose regimen (advantage over oxytocin infusion)
Advantages over Oxytocin:
- Longer duration of action = single dose sufficient
- No need for IV infusion
- More stable at room temperature (heat-stable formulation available - WHO preferred)
- Reduced need for additional uterotonics
- No significant cardiovascular side effects at recommended doses
Side Effects:
- Nausea, vomiting, abdominal pain
- Flushing, headache, tremors
- Hypotension (mild, transient)
WHO Recommendation (2012/2018):
- Carbetocin 100 mcg IV/IM is recommended for prevention of PPH in caesarean section settings
- Heat-stable carbetocin is now preferred in low-resource settings
Contraindications:
- Pre-eclampsia/eclampsia (relative - use cautiously)
- Serious cardiovascular disease
- Hepatic/renal impairment
SAQ 3 - Shoulder Dystocia Management
Definition: Shoulder dystocia is an obstetric emergency where, after delivery of the fetal head, the anterior shoulder fails to deliver spontaneously or with gentle downward traction due to impaction behind the maternal symphysis pubis.
Incidence: 0.24-2% of vaginal deliveries
Risk Factors:
- Antenatal: Fetal macrosomia (>4000 g), GDM, maternal obesity, prior shoulder dystocia, previous macrosomic baby
- Intrapartum: Prolonged 2nd stage, operative vaginal delivery (mid-cavity), oxytocin augmentation
- Note: 50% of cases have NO identifiable risk factor
Recognition: "Turtle sign" - fetal head delivers but retracts against the perineum; failure of restitution and external rotation.
Management - HELPERR Mnemonic:
| Step | Action |
|---|
| H | Call for Help (senior obstetrician, neonatologist, anaesthetist, extra midwife) |
| E | Episiotomy - does not relieve bony dystocia but creates room for maneuvers |
| L | Legs - McRoberts maneuver (hyperflexion of thighs onto abdomen) - FIRST STEP |
| P | Pressure - Suprapubic pressure (Rubin's maneuver) - downward and lateral |
| E | Enter - Internal rotational maneuvers (Rubin II, Woods screw, Barlow's) |
| R | Remove posterior arm - delivery of the posterior arm |
| R | Roll the patient - Gaskin all-fours position (Gaskin maneuver) |
Maneuvers in Detail:
-
McRoberts Maneuver (FIRST - used in >40% cases)
- Hyperflexion and abduction of maternal thighs onto abdomen
- Straightens lumbar lordosis, rotates symphysis pubis superiorly
- Increases relative A-P diameter of pelvis
- 40-42% success rate alone or combined with suprapubic pressure
-
Suprapubic Pressure (Rubin's)
- Applied by assistant above symphysis pubis
- Directed downward and laterally to dislodge anterior shoulder
- NOT fundal pressure (worsens impaction)
-
Internal Rotational Maneuvers:
- Rubin II: Pressure on posterior aspect of anterior shoulder to rotate fetus
- Woods Screw: Pressure on anterior aspect of posterior shoulder (rotate 180°)
- Barlow: Combination of Rubin II + Woods (reverse screw)
-
Delivery of Posterior Arm:
- Hand sweeps posteriorly to deliver posterior arm
- Reduces biacromial diameter
-
Gaskin Maneuver (All-Fours):
- Flip patient to hands-and-knees position
- Gravity aids disimpaction; most effective last resort
-
Last Resort Maneuvers:
- Zavanelli maneuver (cephalic replacement followed by caesarean section)
- Deliberate clavicle fracture
- Symphysiotomy (developing countries)
DO NOT: Apply fundal pressure, apply excessive traction, attempt rotation before disimpaction.
Complications:
- Maternal: PPH, 3rd/4th degree perineal tears, bladder injury
- Fetal: Brachial plexus injury (Erb's palsy 10-20%), clavicle/humerus fracture, hypoxia/asphyxia, death
SAQ 4 - Induction of Labour (IOL)
Definition: Induction of labour is the artificial initiation of uterine contractions before spontaneous onset of labour, after fetal viability, with the intention of achieving vaginal delivery.
Indications:

|---|
| Dilatation (cm) | Closed | 1-2 | 3-4 | 5+ |
| Effacement (%) | 0-30 | 40-50 | 60-70 | 80+ |
| Station | -3 | -2 | -1/0 | +1/+2 |
| Consistency | Firm | Medium | Soft | - |
| Position | Posterior | Mid | Anterior | - |
- Score ≥8: Favourable cervix - oxytocin can be used
- Score <6: Unfavourable - cervical ripening needed first
Methods of IOL:
A. Cervical Ripening (Unfavourable Cervix):
- Prostaglandins:
- PGE2 (Dinoprostone): Gel 0.5 mg intracervical or 1-2 mg vaginal; maximum 3 doses 6-hourly
- PGE1 (Misoprostol): 25-50 mcg vaginally or sublingually 4-6 hourly; cheap, heat-stable
- Balloon/Foley catheter: Mechanical ripening by pressure; useful in scarred uterus
- Membrane sweeping (stretch and sweep): Done at 38-40 weeks; releases endogenous prostaglandins
B. Amniotomy (ARM - Artificial Rupture of Membranes):
- Forewater rupture with amniohook
- Used when cervix is favourable (Bishop ≥6-8)
- Increases prostaglandin release, allows head to press on cervix
- Augmented with oxytocin if contractions don't establish within 1-2 hours
C. Oxytocin Infusion:
- Low-dose protocol: Start at 1-2 mIU/min, increase by 1-2 mIU every 30-40 min
- High-dose protocol: Start 4-6 mIU/min, increase every 15-40 min
- Titrate to 3-4 contractions in 10 minutes, each lasting 45-60 seconds
- Maximum dose: 20-40 mIU/min
- Side effects: Uterine hyperstimulation (tachysystole), fetal distress, water intoxication (hyponatraemia), amniotic fluid embolism
Complications of IOL:
- Failed induction (leading to caesarean section)
- Uterine hyperstimulation / Uterine rupture
- Cord prolapse (after ARM)
- Fetal distress
- Infection
- Placental abruption
SAQ 5 - PCOS (Polycystic Ovary Syndrome)
Definition: PCOS is a heterogeneous endocrine disorder characterized by hyperandrogenism, oligo/anovulation, and polycystic ovarian morphology on ultrasound.
Diagnostic Criteria - Rotterdam Criteria (2003):
2 of the following 3 features required:
- Oligo/anovulation
- Clinical/biochemical signs of hyperandrogenism
- Polycystic ovarian morphology on USG (≥12 follicles 2-9mm per ovary OR ovarian volume >10 mL)
Other exclusion criteria: CAH, hyperprolactinaemia, thyroid disease must be excluded.
Pathophysiology:
- Increased LH pulsatility from hypothalamus
- Elevated LH:FSH ratio (>2:1 or >3:1)
- Excess androgen (mainly testosterone) from theca cells
- Arrested follicular development at 5-10 mm (follicular arrest)
- Insulin resistance → compensatory hyperinsulinaemia → stimulates androgen production
- Decreased SHBG → more free androgens
Clinical Features:
- Menstrual irregularities: Oligomenorrhoea, amenorrhoea, irregular cycles
- Hyperandrogenism: Acne, hirsutism, male-pattern alopecia
- Obesity (central adiposity) in 50%
- Subfertility/infertility (anovulatory)
- Acanthosis nigricans (insulin resistance)
- Psychological: Depression, anxiety
Investigations:
- LH, FSH (elevated LH:FSH ratio)
- Testosterone (free and total), DHEAS
- Fasting insulin, glucose, HOMA-IR
- Pelvic ultrasound (TVS preferred)
- Prolactin, TSH (to exclude differential diagnoses)
- Lipid profile, 2-hour GTT (screen for metabolic syndrome)
Long-term Complications:
- Type 2 Diabetes mellitus
- Metabolic syndrome
- Cardiovascular disease
- Endometrial hyperplasia/carcinoma (from chronic anovulation)
- Obstructive sleep apnoea
- Subfertility
Management:
Lifestyle Modification (First-line for overweight/obese):

- Metformin - Insulin sensitizer; improves ovulation, especially with CC
- Letrozole (aromatase inhibitor) - Now preferred over CC (better outcomes, less multiples)
- Gonadotrophins - FSH injections; risk of OHSS; requires monitoring
- Laparoscopic Ovarian Drilling (LOD) - Surgical; destroys androgen-producing tissue; alternative to gonadotrophins
- IVF - If above fail
Metabolic:
- Metformin for insulin resistance/type 2 DM

Key Marker: Beta-hCG (human chorionic gonadotropin) - used for diagnosis, monitoring response, and detecting relapse.
FIGO Anatomic Staging:
| Stage | Description |
|---|
| I | Confined to uterus |
| II | Extends beyond uterus, confined to genitalia |
| III | Pulmonary metastases |
| IV | All other metastases (brain, liver, kidney) |
WHO Prognostic Scoring:

Follow-up:
- Weekly hCG until normal x3, then monthly for 12 months
- Avoid pregnancy for 1 year after completing treatment
Prognosis: Excellent - GTN is one of the most curable gynecological malignancies. Subsequent fertility is preserved.
Q.2 LAQ ANSWERS
LAQ 1 - Puerperal Pyrexia: Definition, Etiology, and Management of Puerperal Sepsis
Definition of Puerperal Pyrexia:
Puerperal pyrexia (puerperal fever) is defined as a temperature of 38°C (100.4°F) or higher occurring on any 2 of the first 10 days postpartum (excluding the first 24 hours), measured orally.

LAQ 3 - Infertility: Definition, Cervical, Uterine and Tubal Factors
Definition of Infertility:
Primary Infertility: Failure to achieve a clinical pregnancy after 12 months or more of regular unprotected sexual intercourse (WHO), in women who have never been pregnant.
Secondary Infertility: Failure to achieve a clinical pregnancy after 12 months or more of regular unprotected sexual intercourse, in women who have previously been pregnant (regardless of outcome).
Sub-fertility: Any form of reduced fertility with prolonged time to conception.
Prevalence: Affects ~10-15% of couples worldwide; in India, approximately 10-14%.
Causes of Female Infertility (Overview):
- Ovulatory factors: 25-30%
- Tubal factors: 25-30%
- Uterine factors: 10%
- Cervical factors: 5%
- Unexplained: 10-15%
- Combined/multiple factors: 10-15%
A. Cervical Factors
Normal Cervical Function in Fertility:
- At mid-cycle (peak oestrogen), cervical mucus becomes thin, watery, acellular (Spinnbarkeit - stretches >6 cm), alkaline (pH 7-8.5) - facilitates sperm penetration
- Crypts in endocervical canal act as sperm reservoir (capacitation)
Causes of Cervical Factor Infertility:
-
Cervical Mucus Abnormalities:
- Hostile cervical mucus: Thick, viscid, acidic, cellular - at mid-cycle (poor oestrogen response)
- Immunological: Anti-sperm antibodies (ASAb) in cervical mucus - agglutinate or immobilize sperm
-
Structural Cervical Defects:
- Cervical stenosis (post-cone biopsy, LLETZ, cryotherapy, D&C, infection)
- Cervical incompetence (usually causes miscarriage, not infertility per se)
- Cervical polyps
-
Infections:
- Chlamydia, gonorrhoea: Cause cervicitis; hostile mucus
- Bacterial vaginosis: Alters vaginal/cervical environment
-
Iatrogenic:
- Previous cervical surgery (LLETZ, conisation) - reduces mucus-producing crypts
- Post-radiation changes
Assessment:
- Post-coital test (PCT/Sims-Huhner test) - performed at mid-cycle, 6-24h after intercourse; normal = >20 actively motile sperm per HPF
- Cervical mucus score (Insler score)
- Anti-sperm antibody testing (serum and mucus)
- Cervical swabs (infection screen)
Management of Cervical Factor Infertility:
- Anti-sperm antibodies: Condom use for 3-6 months (reduce antigen exposure), corticosteroids (controversial), IUI
- Hostile mucus: Oestrogen supplementation; IUI (bypasses cervix entirely)
- Cervical stenosis: Dilatation; IUI
- Infection: Antibiotics (doxycycline for chlamydia, partner treatment)
- IUI is the primary treatment bypassing cervical factor
- IVF if IUI fails
B. Uterine Factors
Normal Uterine Function:
- Uterine cavity must be normal for implantation
- Endometrium must undergo proper proliferative-secretory changes
Causes of Uterine Factor Infertility:
-
Congenital Uterine Anomalies (Mullerian anomalies):
- Arcuate uterus (mildly bicornuate): Minimal impact on fertility
- Septate uterus: Most common anomaly causing RPL and infertility; septum is avascular
- Bicornuate uterus: Affects implantation
- Unicornuate uterus: Reduced uterine volume
- Didelphys uterus: Double uterus
- Agenesis/hypoplasia (Mayer-Rokitansky-Kuster-Hauser syndrome)
-
Acquired Lesions:
- Fibroids (Leiomyomata):
- Submucosal: Greatest impact on fertility (distort cavity, affect implantation)
- Intramural: Impact if >4-5 cm (compress cavity)
- Subserosal: Least impact on fertility
- Endometrial polyps: Interfere with implantation; may be found incidentally
- Asherman's Syndrome (Intrauterine adhesions/synechiae):
- Cause: Previous D&C (especially post-abortion/post-partum), infection, surgery
- Features: Hypomenorrhoea/amenorrhoea, dysmenorrhoea, infertility, RPL
- Diagnosis: Hysteroscopy (gold standard); SIS; hysterosalpingography (HSG)
- Treatment: Hysteroscopic adhesiolysis + post-op oestrogen + IUD/balloon to prevent re-adhesion
- Endometritis: Chronic endometritis (plasma cell infiltration); often asymptomatic
- Endometriosis (uterine involvement): Adenomyosis reduces implantation
Assessment:
- Pelvic USS (2D/3D)
- Saline infusion sonography (SIS) / Sonohy sterography - for cavity lesions
- Hysterosalpingography (HSG) - outlines cavity + tubes
- Hysteroscopy (gold standard for uterine cavity)
- MRI pelvis - for Mullerian anomalies, deep adenomyosis
Management of Uterine Factors:
- Uterine septum: Hysteroscopic resection of septum (metroplasty) - improves pregnancy rates
- Submucosal fibroids: Hysteroscopic myomectomy; laparoscopic/open myomectomy for large intramural fibroids
- Asherman's syndrome: Hysteroscopic adhesiolysis
- Polyps: Hysteroscopic polypectomy
- Congenital anomalies: Bicornuate - Strassman's metroplasty; Unicornuate - counselling
- Endometritis: Doxycycline + metronidazole
C. Tubal Factors
Tubal factor infertility (TFI) is responsible for 25-30% of all female infertility. Fallopian tubes transport gametes, provide site for fertilization, and transport the embryo to uterus.
Causes:
-
Pelvic Inflammatory Disease (PID):
- Most common cause of TFI worldwide
- Organisms: Chlamydia trachomatis (most common in developed countries), Neisseria gonorrhoeae, anaerobes
- Each episode of PID increases risk: 1 episode = 12%, 2 episodes = 25%, 3 episodes = 54%
- Causes peritubal adhesions, tubal scarring, blocked fimbriae
-
Endometriosis:
- Peritoneal endometriosis creates peritubal adhesions and occlusion
- Affects tubal motility and pickup function
-
Previous Pelvic/Abdominal Surgery:
- Appendicectomy (especially ruptured appendix)
- Previous tubal surgery, ectopic pregnancy surgery
- Peritonitis (any cause)
- Ovarian cystectomy
-
Congenital:
- Tubal aplasia/hypoplasia (rare; associated with other Mullerian anomalies)
-
Previous Ectopic Pregnancy:
- Salpingectomy removes tube
- Salpingotomy leaves damaged tube
-
Tuberculosis (TB) of the female genital tract:
- Major cause of TFI in India and developing countries
- Causes cornual block, rigid "pipe-stem" tubes, caseous nodules
- HSG shows beaded appearance, irregular filling, calcification
-
Post-septic abortion
Types of Tubal Damage:
- Hydrosalpinx: Distally occluded tube filled with fluid; has toxic effect on endometrium and embryos (reduces IVF success by 50%); salpingectomy recommended before IVF
- Proximal tubal block: Cornual block on HSG - may be spasm (false positive); confirmed by laparoscopy
- Peritubal adhesions: Tubes patent but function impaired
Assessment:
-
Hysterosalpingography (HSG):
- Outpatient radiological procedure
- Contrast injected through cervix; visualizes uterine cavity and tubal patency
- Fallopian tubes fill and spill freely if patent
- Disadvantages: Radiation, cannot assess peritubal adhesions, may miss fimbrial disease
- Therapeutic effect: Increases pregnancy rates for ~3 months after
-
Laparoscopy with Chromotubation:
- Gold standard for tubal assessment
- Methylene blue dye injected transcervically and observed for spill from fimbriae
- Also assesses peritubal adhesions, endometriosis (not visible on HSG)
- Invasive - requires general anaesthesia
-
Sonosalpingography / HyCoSy: Uses ultrasound contrast; avoids radiation; good for outpatient assessment
Management of Tubal Factor Infertility:
Surgical:
-
Tubal Surgery (Tubal Reconstruction):
- Salpingolysis: Division of adhesions around tubes
- Fimbriolysis / Fimbriplasty: Opening of fimbrial end
- Neosalpingostomy: Creating new opening in distally occluded tube
- Success rate: 30-50% for mild disease; <10% for severe hydrosalpinx
- Risk of ectopic pregnancy is increased after surgery
-
Tubal Cannulation:
- For proximal tubal obstruction
- Hysteroscopic/fluoroscopic; selective salpingography
-
Salpingectomy:
- For hydrosalpinx before IVF
- Improves IVF success rates by up to 50%
Assisted Reproduction:
-
IVF (In Vitro Fertilisation):
- Treatment of choice for bilateral tubal disease
- Completely bypasses tubes
- Live birth rate per cycle: ~30-40% (age dependent)
- Multiple pregnancy risk with multiple embryo transfer
-
IUI (Intrauterine Insemination): Not effective for tubal disease (cannot bypass block)
Special - Tuberculosis:
- Anti-TB treatment (ATT) for 6-9 months
- Tubal surgery generally ineffective (extensive fibrosis)
- IVF is the treatment of choice for TB-related TFI
