Gynae Flashcards
Anti-D need in pregnancy for Rh-ve women (non -sensitised)
Any surgical management of miscarriage ectopic
- Needs anti-D
Medical/ expectant miscarriage management at any time
- NO
TOP
- Surgical - give anti-D at any time
- Medical - Give after 10 weeks
Potential miscarriage tests to do
EPAU
TVUS - see if fetus present and viable
- repear in 1 week if doubt (2weeks if abdo)
Blood: bHCG 48h should up by 66% if viable
Progesterone
FBC and inflammatory markers
Group and save if bleeding
Speculum
- If os open deficintely miscarriage
Miscarriage management
Follow up
Contraindications to conservative/medical options
Missed
- 1st line: Expectant for 7-14 days
- Medical - misoprostol
- Surgical - manual vacuum aspiration
Generally
C: Sometimes women’s bodies will pass the pregnancy tissue spontaneously.
If woman willing, no infection, no haemodynamic instability. Within 2-6 weeks
50% success
M: We can give you a tablet to help you pass the pregnancy tissue at home. Misoprostol 600mg PO or PV. - MSD must be <50, CRL <30 - No haemodynamic compromise 85% success
MEDICAL AND EXPECTANT NEED FOLLOW UP IN 1-2 weeks.
“If bleeding is so heavy that you need to change pads more than once every 15 mins or you pass a clot the size of your palm, come back to EPAU or go to A&E”
S: Will be put to sleep and the pregnancy tissue will be removed using gentle suction
SMM - histology for all
- CI if >18/40 usually
- SE: Asherman’s, perforation, Repeat needed, infecton
“Possibility of not removing enough or removing too much tissue plus risks associated with any procedure”
95% success
PUL define
Causes
Management
+ve pregnancy test but can’t see pregnancy in uterus
Causes
- Early
- Miscarriage
- Ectopic (esp if pain and bleeding)
Follow up
Serial HCG (63-66% increase in 48h suggests viable)
- Up 63% or more - US in 7-14 days
- Down more than 50% - Unlikely pregnancy. Pregnancy test in 2 weeks
- Change between the 2: refer to EPAU
Ectopic causes
PID Previous ectopic Any surgery to pelvis Endometriosis? Smoking IVF IUD in situ
Symptoms
- Lower abdo pain - colicky then constant
- Shoulder tip pain (phrenic nerve -C3-4 same cervical nerve origin as supraclavicular)
- Classical ‘abdo pain’, amenorrhoea and vaginal bleed
- D&V!!!!!
O/E
- Tachycardia
- Hypotension = severe
- rebound tenderness
- Cervical excitation
Ectopic investigation
Urinary hCG for any woman with pain, bleed, collapse
TVUS (<9/40) or TAUS (>9/40)
- Result will be PUL, PUV, Ectopic (bagel sign), Free fluid/blood clot or gestation sac +/- fetus in adnexae
Serial bHCG
- > 1,000: intrauterine pregnancy should be visible
- <1,000 but rising 66% in 48h - early but intrauterine likely
- Declining/plateauing = ectopic or non-viable IU preganncy
Progesterone
- <20: Likely failing pregancy
- 20-60: High risk of ectopic
- > 60 Suggests progressing pregnancy, likely IU
MOST SENSITIVE TEST = LAPAROSCOPY
- HCG and US allows for fewer -ve laps
Ectopic management
Symptoms –> admission. IV access and cross match.
Anti-D if Rh-ve
Conservative only if <1000 and declining + NO pain
. Careful observation
No pain, unruptured, no heart beat, adnexal mass <35, not intrauterine, HCG between 1500-5000 (ideally <1500)
- Choice of methotrexate or surgery
- Methotrextate 1 dose. HCG day 4 and 7, weekly until -ve
10% still rupture, 15% require second dose. Wait 3 months to try again
If haemodynamically unstable
- Resuscitation, laparoscopy or laparotomy
- Salpingectomy
Hyperemesis gravidarum
Define
Investigations
Greates risk factors
Management

Investigations
- Abdo exam
- PUQE
- Urine dip +/- MSU (>1ketones - admit) UTI?
- Bloods: U&E, LFTs, TFTs, HCG, Ca, Mg
- Abdo US: Multiple, molar?
Management
- ABCDE
C: assess dehydration.
- Anti-emetics e.g. Cyclixine, metoclopramide, ondansetron.
- Fluid resus and maintenance.
- VTE prophylaxis
D:
- Folic acid!
- Thiamine!
- Re-feeding
E: xclude other causes
- Urinalysis +/- MSU

Complications
- Mallory Weiss tear
- Wernicke’s encephalopathy
- Renal damage
POP mechanism of action

Window for taking
What if antibiotics given?
Thickens cervical mucus
- Inhibits ovulation in 50%
CI:
Liver disease
Current/past breast cancer
Stroke/CHD
3 h (12 for cerazette)
- Take as soon as remember
- 2 days extra protection if out of this window
What if antibiotics given?
Nothin - all good - UNLESS alter p450 system e.g. rifampicin
Contraindications to Nexplanon
Mechanism of action

Hx/current breast cancer
Liver cirrhosis
Stoke/TIA whilst on implahnt
MOA:
Inhibits ovulation!!!
Depo-provera
Contraindications
IM injecton every 12 weeks
WEIGHT GAIN PROVEN
Contraindications
- Breast cancer within 5y
- Severe arterial disease or risk factors
- Pregnancy
- Diabetes with vascular disease
- People who will want fertility to return quickly (takes 1 yr)
Emergency contraceptions
IUD- copper
= Immediate and most effective
<5 days (120h) after UPSI, apparently 5 days after likely ovulation is ok too??
- Risks: Infection, bleeding, puncturing, expulsion
Levonorgestel aka progesterone (Inhibits ovulation and stops implantation) <72h of UPSI (84% effective) - More effective the sooner it's taken - SE: Nausea, vom, dizzy, abdo pain - Take again if vomit within 2 h - Affects next period - Take 2 if BMI >26
Ulipristal acetate aka selective progesterone receptor modulator (Inhibits ovulation)
<120h of UPSI
- More effective the sooner it’s taken
- SE: Painful peridos, mood swins, aches
- Take aain if vomit in 3 h
- Delay breasfeeding for 7 days after taking
MEDS NEED PREGNANCY TEST 3 weeks after UPSI
- ALSO do if you don’t have period within 3 weeks of taking
- Abstain until next period
CONTRAINDICATIONS
To the tablets: no absolute contraindications but certain things may make it less effective e.g. malabsorption problems, enzyme inducing drugs e.g. rifampicin
- Avoid breastfeeding 7 days after Ulipristal acetate
To copper IUD:
- Copper allergy
- Fibroids distorting cavity
- PID/STI suspected
Always GUM clinic, safegurarding, safety net, safe sex in the future!!
Female sterilisation
Options
Success
Disasvantages
Tubal ligation with flishie clips = GA laproscopic.
or
Transcervical sterilisation = hysteroscopy
- needs confirmation 3 m after
Failure 1/200
Can’t be reversed. Doesn’t affect periods
Avoid sex for 1 week after
Contraception for 4 weeks (3m if transcervical)
Under 25s contraception
Best = Implant
Grade 2 are IUS and IUD if <20
Depo-provera = concerns about bone mineral density
Remember consent rules
- Capacity
- Won’t tell parents
- Likely to have sex with or without
- Physical/mental health will suffer without
- Best interests
NB: <13 cannot consent. CHILD PROTECTION
