Reproductive Flashcards
Antenatal care timetable
What do late decelerations indicate?
Deceleration of the heart rate which lags the onset of a contraction and does not returns to normal until after 30 seconds following the end of the contraction
Indicates foetal distress e.g. asphyxia or placental insufficiency
Ix: urgent foetal blood sampling (foetal hypoxia, acidosis).
* pH >7.2 in labour = normal
Mx: Urgent delivery should be considered if foetal acidosis
Give an overview of the disorders of reproductive development incl definition of primary amenorrhoea, problems in HPG axis and structural abnormalities
Primary amenorrhoea:
* No periods by 13yrs + no secondary sexual characteristics
* No periods by 15yrs + normal secondary sexual characteristics
Secondary amenorrhoea - prev periods but stopped for ≥6m
HPG Axis: Kisspeptin –> signal to start puberty –> Hypothalamus –GnRH–> pituitary –FSH/LH–> ovary –> follicles –oestrogen–> -ve/+ve feedback on hypothalamus (depending on position in menstrual cycle)
Axis problems can occur at:
* Hypothalamus - HYPOthalamic HYPOgonadism (low FSH/LH –> low oestrogen):
* Functional hypothalamic amenorrhoea (low BMI, exercise, stress)
* Kallmann’s syndrome - failure of neurone migration (+ reduced smell)
* Systemic - hyper/hypothyroidism, congenital adrenal hyperplasia, virilizing tumours
* Pituitary - pituitary HYPOgonadism (low FSH/LH –> low oestrogen):
* Sheehan’s syndrome - infarction of pituitary after haemorrhage e.g. labour (panhypopituitarism)
* Pituitary tumour esp. prolactinoma (Mx: cabergoline/bromocriptine)
* Ovary - ovarian pathology (prepuberty/later, high FSH/LH, low oestrogen)
* POI/menopause - no more eggs –> no more oestrogen made
* Turner’s syndrome - streak ovaries, nothing prod oestrogen
* Gonadal dysgenesis, androgen insensitivity
Structural problems - outflow obstruction (no period)
* Imperforate hymen(& cervical stenosis) - tight seal across vagina, blood stuck in uterus despite periods = hematocolpos
* Rokitansky (MRKH) syndrome —> disorders of development esp. vagina (& uterus) –> exam under anaesthesia + neovagina formation
* Asherman’s syndrome - after surgical miscarriage/ToP - IU adhesions (also related to endometriosis/PID) –> endometrium not producing thickened layer with each cycle –> no blood prod
Fertility
* Regular sexual intercouse (2-3x/wk) - 84% conceive within 1yr, 92% within 2yrs
* Ix: if failed to conceive after 1yr of reg unprotected sexual intercourse, male - semen analysis (repeat after 3m if abn), women - mid luteal phase D21 progesterone (7d before expected period) +/- D2-4 LH/FSH, TSH, prolactin
* Mx: refer to fertility services if <36yrs and failed to conceive after 1yr
Give an overview of PCOS
Rotterdam criteria (req 2/3 + exclusion of other dx)
* Irregular/absent ovulations (cycle >42 days, >2yrs) - ≤3 menstruations/year in PCOS increases risk of endometrial hyperplasia/carcinoma
* Clinical/biochem hyperandrogenism (acne, alopecia, hirsutism)
* USS polycystic ovaries (≥12 antral follicles in one ovary, measuring >2mm on one ovary/ovarian volume >10ml)
Ix:
* Preg test, LH/FSH (high), TFTs, prolactin (slight high), testosterone on day 2-5 of cycle for ‘basal’ reference range (x2)
* TVUS ‘string of pearls’ sign
* Karyotype (if absent uterus/Turner’s worry)
Mx:
* Conservative - WL/Sx control
* Medical: Dianette COCP (increased VTE risk)/LNG-IUS, Metformin
* Fertility Tx: WL, ovulation induction (<6m) - clomifene (SERM) +/- metformin (others - letrozole, low-dose step-up exog gondatrophins), other - laparoscopic ovarian drilling, IVF
Menopause overview
Menopause = final permanent cessation of menstruation after 12 months amenorrhoea, average age 51/52yrs
* Ovaries stop producing eggs –> ovaries stop produces oestrogen (and progesterone) –> symptoms
PC:
* Vasomotor - poorly tolerated temperature changes e.g. hot flushes (± night sweats)
* Menstrual irregularities
* Breast tenderness, vaginal dryness –> dyspareunia, reduced libido
* Low mood (impending doom), fatigue, sleep disturbance
Diagnosis
* >45yrs by clinical presentation/no Ix needed after 12m amenorrhoea
* 40-45 = early menopause
* <40yrs = Premature ovarian failure/POI
Ix: preg test, serum FSH (2, 4-6wks apart) - normally used if <40yrs (sometimes if 40-45) –> elevated FSH suggests menopause if amenorrhoea
HRT:
* Oestrogen replacement ONLY if have had hysterectomy (risk of endometrial cancer)
* Combined oestrogen and progesterone if have uterus as progesterone is protective against endometrial cancer
* Cyclical- if menses: oestrogen tablet OD, progestogen (norethisterone) on last 14 days of the cycle (depending how often)
* After 1yr cyclical therapy/established menopause (no withdrawal bleeding -> combined Tx daily
* For POI –> treatment with OCP/HRT until 51yrs (av age menopause)
Urogenital atrophy –> vaginal oestrogen ± vaginal lubricants/moisturisers
HRT risks/benefits:
- Combined HRT gives small increased risk of breast cancer
- Increased risk of blood clots (VTE) with tablets but not patch
- No sig increased risk of CVD if started before 60yrs (heart disease, stroke)
- Reduces risk of osteoporosis
Causes of antepartum haemorrhage
BLEEDING IN LATE PREGNANCY = PLACENTAL ABRUPTION, placenta praevia - painless/vasa praevia - painless with Rupture of membranes (RoM)
* Dark bleed in abruption vs fresh and profuse with praevia
* Foetus lie may be abnormal in praevia
Placenta praevia - placenta in lower segment uterus
* PC: painless PV bleed, abn lie/breech, USS incidental findings
* Ix: bloods, CTG, USS
* Mx: if ≤20wks - wait until 36wks -> if <2cm from OS for elective CS, if acute bleed admit ?delivery
Vasa praevia - fetal blood vessels are unprotected by the umbilical cord or placenta and run near the cervix
Placental abruption - separation of normally sited placenta from uterine wall -> maternal haemorrhage into intervening space
* PC: Sudden onset constant abdo pain, tense woody uterus, can have ‘concealed’ bleeding
* Ix: urine, speculum (blood pooling), CTG (long deceleration), USS
* Mx: stabilise, <34wks stable - observe, CS, delivery at 37-38wks, >34wks - IoL if stable
Post-partum haemorrhage overview
Definition: >500ml (>1L emergency call, >1.5L 2222), primary = <24hrs, secondary >24hrs
Causes (4Ts):
* Tone 70% - atonic uterus = uterus slow to contract (possibly given synto for too long)
* Trauma 20% - episiotomy/tears/CS
* Tissue 10% - retained placenta/fragments
* Thrombin (clotting) <1% - abruption/PET (pre-eclampsia)/DIC, vWF/Haemophilia
Ix: red blood from closed os, boggy uterus
Mx:
* Bimanual compression
* Syntocinon IV (2nd - Ergometrine IM/Carboprost IM/Misoprostol PR)
* Surgery - EUA, direct uterine massage, uterine packing, balloon compression +/- hysterectomy
VTE in pregnancy Ix & Mx
Ix:
* Exertional HR/sats
* ECG, US doppler LL (D-dimer not appropriate = already raised in preg)
* CTPA, can offer VQ scan instead ±CXR
* CTPA has increased radiation for mother breast tissue, less for baby
* If can’t identify anything on VQ would have CTPA anyway
* Magnetic Resonance Venography (MRV)
Management
* Conservative – compression stockings + elevation
* LMWH throughout pregnancy + 3-months post-partum
* Haem follow-up @3-months PP
Give an overview of problems during labour
Shoulder dystocia
* Impaction of anterior foetal shoulder on maternal pubic symphysis
* Assoc w/ postpartum haemorrhage + perineal tears in mum and brachial plexus injury in foetus
BIG RISK TO BABY = BRACHIAL PLEXUS INJURY
* Damage to upper brachial plexus - Erb’s palsy - “waiter’s tip” (adduction + internal rotation of arm + pronation of forearm)
* Damage to lower brachial plexus - Klumpke’s palsy - affects nerves innervating hand muscles
Management
* McRoberts – take legs straighten and re-bend again = 90% EFFECTIVE
* Episiotomy gives more room for later manoeuvres:
* Suprapubic pressure followed by Woodscrew’s/Reverse Woodscrew’s manoeuvre (2 fingers on either side – behind anterior shoulder and in front of posterior shoulder –> rotate baby)
* Delivery of posterior arm
* All fours and repeat above
* Finally – Cleidotomy (breaking baby’s clavicle)/Symphysiotomy (cut mum’s symphysis pubis)/Zanvenelli (push baby back inside mum and do CS)
Placental abruption - covered in antepartum haemorrhage card
Breach presentation Mx:
* External cephalic version (rotate baby manually) –fail–> EMCS
* Elective CS
Umbilical cord prolapse
* Umbilical cord presentation = membranes intact

* Mx: Relieve pressure on cord – elevate presenting part, all fours position and deliver
Foetal bradycardia
* Deceleration – drop from baseline >15 for >15s
* Bradycardia - >3 mins deceleration
* Mx: change position (LLP), examine, delivery by fastest/safest route (if does not recover)
Placenta accreta - attachment of placenta to myometrium from defective decidua basalis –> placenta does not properly separate during labour –> risk of post-partum haemorrhage
* Accreta: chorionic villi attach to myometrium, rather than being restricted within decidua basalis
* Increta: chorionic villi invade into myometrium
* Percreta: chorionic villi invade through perimetrium
* Mx:
* Definitive - hysterectomy w/ placenta left in-situ (attempts to actively remove placenta can cause sign haemorrhage)
* Medical: oxytocin/ergometrine - manage post-partum haemorrhage
PERINEAL TEARS - Classification:

Exomphalos vs Gastroschisis
Exomphalos (omphalocele) - bowel contents through umbilicus in sac -> C-section -> gradual closure over 6-12 months
Gastroschisis - bowel contents through defect in abdo wall (not umbilicus) and no sac -> wrap newborn abdo with occlusive wrap (reduce fluid/heat-loss) -> URGENT SURGICAL CLOSURE WITHIN 4HRS
Miscarriage vs Ectopic preg vs
Molar preg Overview
Miscarriage <24wks (most <12wks)
Types:
* Early (<13wks), late (13-24wks)
* Complete (all products of conception expelled, and bleeding stopped)
* Incomplete (non-viable preg but bleeding with RPC)
* Missed (NVP on US scan with pain/bleeding)
* Threatened (vaginal bleed, viable pregnancy in first 24wks)
* Inevitable (NVP, bleeding, cervical os open, RPC)
* Recurrent (3+ consecutive preg before 2wks)
NOTE: pregnancy of uncertain viability = crown-rump length <7mm with no cardiac activity (present by 7-9wks)
TVUS - crown-rump length >7mm + no cardiac activity = Dx miscarriage

* Surgical if high-risk (b-HCG >1500/ruptured/foetal heart beat) - surgery + post-surgical methotrexate + Salphingectomy (not salphingostomy unless contralat tube damaged)
Molar pregnancy - abnormal growth of cells formed from start of embryo, not viable pregnancy
* Complete mole = entirely paternal - 1 sperm fertilises empty oocyte and undergoes mitosis → diploid tissue usually 46 XX, no foetal tissue, just proliferation of swollen chorionic villi)
* Partial mole = two sperms entering one oocyte, usually triploid, variable evidence of foetus
PC:
* Bleeding in first/early second trimester
* Exaggerated Sx of preg e.g. hyperemesis
* Uterus large for dates
