Flashcards
Sx of gestational trophoblastic disease
Bleeding
Hyperemesis
Large for dates
Mid trimester - pe, hyperthyroidism, pul or neuro sx
What types of trophoblastic disease are there and what are their definitions
Complete mole - empty egg that is fertilised by one sperm thAt replicates or 2 sperm. Persistent in 15-25%
Partial mole - triploidy egg + 2 sperm. Persistent in 0.5-4%
Gestational choriocarcinoma - aggressive, arises from term del, top, mc etc. sx mass, bleeding, met sx. Crosses placenta.
Placental site trophoblastic tumour
Epithelioid trophoblastic tumour
Management gtd
D&c and send for histo
Baseline Fbc, u&e, g&h
TFT, cxr, lft, if needed
Inform of risk of invasive disease and risk of recurrence 1/70
Inform of need to avoid pregnancy until fu complete
Moles - wkly hcg until N then cease if partial. Complete monthly for 6/12
Fertility not affected
Gtd - met screen, refer to gynae onc
Assessment of pelvic pain
Cyclic - likely gynae component. Genital swabs, Pap smear, pelvic us. ? Refer to laparoscopy
Git sx - stool culture and stool blood. Fbc, crp, esr.
Sigmoidoscopy ? Colonoscopy
Urinary - urine mcs, urethral swab, renal tract imaging. ? Cystoscopy.
Msk sx - exclude rheumatoid etc diseases, spine and joint X-rays. Consider physio
What are the criteria for forcep delivery?
Cephalic No head above brim Fully Rom At spines or below Bladder empty Adequate analgesia No cephalopelvic disproportion
Initial mx for pph
- D - Call for help - midwives, senior doctors
Hx - GP, hx pph, antenatal hx - placentation, pet, med hx. Nature and duration of labour, tears etc, placenta, meds so far, bloods etc. baby ok? Est ebl so far - R - response
- A - airways. Head down, O2
- B - breathing
- C - circulation - 5 min obs, 2 x wide bore cannulas in cub fos. Send bloods urgently. Start resusc measures fast saline, send for blood products
- Assess for cause
- tone - rub fundus, uterotonics –> oxytocin + infusion, ergo, miso, pgf alpha myometrial
- tissue - placenta complete, feel in vagina for tissue, Mrop if needed, continue fundal rub
- trauma - epis, vaginal or cervical lac
- thrombin
If at any stage unresponsive or unstable obs code pink and prepare for theatre
Surgical mx pph
- Eua and repair lacs
- Compressive measures - bakri, haemostatic brace sutures - b lynch sutures and similar.
- Bilateral ligation of uterine arteries
- Bilateral ligation of internal iliac arteries
Selective emolisation, hysterectomy
Risk factors for pph
5-15% all deliveries Most in primips Grand multips Pix Large uterus Pet Abnormal placentation
Total blood vol = 1ml/kg
Follow up of PPH
Blood replacement as necessary Monitor coats and hb VTE prophylaxis Haematinics Debrief family Plans for future babies
Causes for secondary pph
1/3 unknown Subinvolution - placenta accreta or RPOC Endometritis Other infection eg of cs site Uterine fibroids Polyp or neoplasm AVM Missed lacs or haematomas
Hx for secondary pph
- Pregnancy - intrauterine infection, evidence of aberrant trophoblastic interaction (pet, mc, iugr)
- Delivery - prolonged, mode, difficult 3rd stage, placenta complete, epis, tears etc
- Bleeding characteristics, systemic symptoms, pain
Management secondary pph
- Stabilisation - drabc, NBM, lie flat, O2, obs, call for help as necessary, IV access and send bloods
- Quantification - weigh pads etc and replace as necessary
- Severe - massage uterus or bimanual compression, synt, elevate legs, examine for lacs etc
- Swabs
- Treat for endometritis - ABx
- US and/or hCG
- D&C once stabilised and settled - send for histo pathology
- Anaemia correction
Maternal risks for twin pregnancy
Morbidity and mortality 2.5x that of singletons Symptoms of pregnancy - gord and hyperemesis - wt gain - anaemia and other vitamin defs - take iron and incr folate Increased complications of pregnancy - PET - VTE - GDM - miscarriage, abruption PPROM and infection PTL Polyhydramnios Labour - operative delivery and attendant perineal trauma and surgical complications - need for epidural or similar - cord accident - PPH - Dysfunctional uterine contractions Pst partum - depression - sleep deprivation - financial and relationship strain
Foetal risks of twin delivery
Miscarriage IUGR/ unequal growth preterm del Cerebral palsy Congenital abnormalities TTTS TRAPS TAPS Language and speech impairment
Management of twins
Maternal health - iron sups, folate 5mg, +/- aspirin from 12/40 if other risk factors for PET
Early scan for placentation
Screening for aneuploidy
Foetal surveillance - 2-3/52 from NT and 2/52 from 18. Looking for growth, AFI and bladder as well as dopplers from 24/40
Gestation at birth - aim for 37/40
Incidence of infertility
Below 30yrs fecund ability is 20-25% ea cycle
15% all couples
1/7 30-35, then 1/5, 1/4
Broad classes of infertility
40% poor semen
30% tubal
30% ovulatory
Causes for male infertility
Impotence Retrograde ejaculation Anti-sperm antibodies Congenital factors Acquired urogenital factors - obstruction, torsion, tumour Endocrine Genetic Systemic Gonadal toxins Idiopathic Varicocoele
Nutritional advice for preconception counselling
Appropriate wt gain Screen for eating disorders Healthy balanced diet Refer to dietician / exercise program if needed Avoid uncooked food Toxo and salmonella Limit caffeine Avoid etoh and other drugs Supps - folate, iodine, vit d if needed.
