Obs and Gynae 1 Flashcards
Investigations in suspected PPROM 3 steps
- sterile speculum- to look for pooling of amniotic fluid in the posterior vaginal vault) but digital examination should be avoided due to the risk of infection
- if pooling of fluid is not observed NICE recommend testing the fluid for placental alpha microglobulin-1 protein (PAMG-1) (e.g. AmniSure®) or insulin-like growth factor binding protein‑1
- ultrasound may also be useful to show oligohydramnios
Management of PPROM (5)

5. Deliver at after….. weeks
- admission
- regular observations to ensure chorioamnionitis is not developing
- oral erythromycin should be given for 10 days
- antenatal corticosteroids should be administered to reduce the risk of respiratory distress syndrome
- delivery should be considered at 34 weeks of gestation - there is a trade-off between an increased risk of maternal chorioamnionitis with a decreased risk of respiratory distress syndrome as the pregnancy progresses
What sign on a neonate is an adduction and internal rotation of the arm, with pronation of the forearm and what does it indicate?
Erb’s palsy occurs due to damage to the upper brachial plexus most commonly from shoulder dystocia.
This classic physical position is commonly called the ‘waiter’s tip’.
Talk me through the cervical smear pathway with these different outcomes:
- Who gets tested and how often?
4 categories someone can fit in! - If you keep getting +ve HPV but -ve cytology
The different scenarios regarding inadequate samples
- Who gets tested and how often?
- Up to 6 months before you turn 25
- 25 to 49 = Every 3 years
- 50 to 64 = Every 5 years
- 65 or older = Only if 1 of your last 3 tests was abnormal - If you keep getting +ve HPV but -ve cytology
- Attend and +ve HPV -ve Cytology
- Repeat at 12 months: +ve HPV -ve Cytology
- Repeat at 12 months: Still +ve HPV -ve Cytology
- Send to colposcopy regardless of cytology
- Inadequate samples
- 1 inadequate samples = repeat in 3 months
- 2 consecutive samples send for colposcopy
Miscarriage has occured and decided to treat it expectantly, if this fails and need to treat it medically what do you give them? + route?
Vaginal misoprostol
What is The main complication from induction of labour and what is its management?
med + eg. 3/4
uterine hyperstimulation which is characterised by too frequent or prolonged uterine contractions that can cause significant foetal distress. The treatment of uterine hyperstimulation requires administering tocolytic agents to relax the uterus and slow contractions.
eg. atosiban (oxytocin anatagonist), CCB Nifedipine, Indomethacin (NSAID), Mg Sulfate

Time wondow? (2)
What if patient wants it removed?
Must be inserted within 5 days, or
if a woman presents after more than 5 days then may be fitted up to 5 days after the likely ovulation date
may be left in-situ to provide long-term contraception. If the client wishes for the IUD to be removed it should be at least kept in until the next period

MRI pelvis
Shoulder distocia manoeuvre
1. - Just name
2. Name + action
3. Name + action
4. Action
- McRoberts position
- Rubin manoeuvre (press on the posterior shoulder to allow the anterior shoulder extra room)
- Wood’s screw manoeuvre- Hand in, attempt to rotate foetus 180 degrees.
Can try them when on all 4s
- If this fails you need to push the head back in and do an emergency caesarean section.
Contraception which are contra-indicated if the patient has had a previous gastric sleeve?
AND WHY?
COCP and POP options are inappropriate as oral options will have low EFFICACY in patients with gastric sleeves. Not seen with UKMEC as this covers safety not efficacy.

A- Antibiotics- ciprofloxacin (flouroquinolones), tetracycline (doxycylin), chloramphenicol (Used in eyes), sulphonamides (co-trimoxazole)
A- ACEi
C- Carbimazole (Used in hyperthyroidism- the block in block and replace)
C- Cytotoxic drygs
According the PEARL index, COCP has a score of 0.2, what does this mean?
Pearl Index describes the number of pregnancies that would be seen if one hundred women were to use the contraceptive method in question for one year.
If the medication is adhered to perfectly, we would expect to see 0.2 pregnancies for every hundred women using the pill for one year - or 2 for every thousand.
Risk malignancy index (RMI) prognosis in ovarian cancer, what’s it based on? (3)
US findings, menopausal status and CA125 levels
Definitions of miscarriages:
Threatened miscarriage (2)
Missed (delayed) miscarriage (3)
Inevitable miscarriage (2)
Incomplete miscarriage (3)
Threatened miscarriage:
- painless bleeding < 24 wks typically 6-9 wk
- cervical os closed
Missed (delayed) miscarriage
- gestational sac which contains dead fetus < 20 wks WITHOUT symptoms of expulsion
- os closed
- If gestational sac is > 25 mm and no embryonic/fetal part can be seen it is sometimes described as a ‘blighted ovum’ or ‘anembryonic pregnancy’
Inevitable miscarriage
- heavy bleeding with clots and pain
- cervical os is open
Incomplete miscarriage
- not all products of conception have been expelled
- pain and vaginal bleeding
- cervical os is open

Asthmatic- nifedipine and hydralazine
How far does the placenta invade?
Accreta-
Increta-
Percreta-
accreta: chorionic villi attach to the myometrium, rather than being restricted within the decidua basalis
increta: chorionic villi invade into the myometrium
percreta: chorionic villi invade through the perimetrium
What is Ashermans Syn?
Asherman’s syndrome, or intrauterine adhesions, may occur following dilation and curettage. This may prevent the endometrium responding to oestrogen as it normally would.

Management of barn door vaginal thrush?
1) First line + dose
2) If CI? + dose
3) If vulval symptoms….
If preg then….
HbA1c- A blood test to exclude diabetes should be considered in women with recurrent vaginal candidiasis
Management:
1) oral fluconazole 150 mg as a single dose first-line
2) clotrimazole 500 mg intravaginal pessary as a single dose if oral therapy is contraindicated
3) If there are vulval symptoms, consider adding a topical imidazole in addition to an oral or intravaginal antifungal
if pregnant then only local treatments (e.g. cream or pessaries) may be used - oral treatments are contraindicated

1.
2.
3.

Protective factors 3
RFs
prematurity
multiparity
