Diagnosis?
Typically bleeding in 1st or early 2nd trimester ass. with exaggerated symptoms of pregnancy eg. Hyperemesis. The uterus may be large for dates and serum hCG is very high
Hydratidiform Mole
Diagnosis?
Constant lower abdo pain, and women may be more shocked than is expected by visible blood loss. Tender, tense uterus with normal lie and presentation. Foetal heart may be distressed
Placental Abruption
Diagnosis?
Vaginal bleeding, no pain. Non-tender uterus but lie and presentation may be abnormal.
Placental Praevia
NB - VE should not be done in primary care setting as women with Placental Praevia may haemorrhage
Diagnosis?
Rupture of membranes followed immediately by vaginal bleeding. Foetal bradycardia is classically seen.
Vasa Praevia
Medical Treatment for Bacterial Vaginosis?
PO 400 mg metronidazole BD for 5-7 days
Or PO metronidazole 2 grams STAT (unless pregnant)
Or intravaginal metronidazole gel or intravaginal clindamycin cream
Medical Treatment for Trichomoniasis?
PO 400 mg metronidazole BD for 5-7 days
Or PO metronidazole 2 grams STAT (unless pregnant)
Or PO Tinidazole 2 g STAT (unless pregnant)
Treatment for Chlamydia
PO 1g Azithromycin STAT
Or
PO doxycycline 100mg BD 7/7
Mechanism of the Implantable contraceptive (Etonogestrel)
Prevents endometrial proliferation
Mechanism of the copper IUD
Decreases sperm motility and survival
Mechanism of Progesterone-only pill (excluding desogestrel)?
Thickens cervical mucus
Mechanism for Desogestrel-only pill?
Primary: inhibits ovulation
Also: thickens cervical mucus
Mechanism for injectable contraceptive (medroxyprogesterone)?
Primary: inhibits ovulation
Also: thickens cervical mucus
Mechanism for IUS (Levonorgestrel)?
Primary: prevents endometrial proliferation
Also: thickens cervical mucus
Causes for Primary Postpartum Haemorrhage?
Tone - uterine atony
Tissue - retained placenta
Trauma
Thrombin - coagulation abnormalities
What is the definition of premature ovarian failure?
The onset of menopausal symptoms and elevated gonadotropin levels before the age of 40 years
Features of PID?
Lower Abdo pain Fever Deep dyspareunia Possible dysuria and menstrual irregularities Vaginal/cervical discharge Cervical excitation
What day does the morula normally implant?
Day 6
What day does the zygote normally enter the uterus?
Day 4
When is placental morphology normally complete by?
12 weeks
When is a foetal heart beat normally established?
4-5 weeks
When can a foetal heart beat normally be detected by transvaginal ultrasound?
5-6 weeks
What type of miscarriage is this?
There is bleeding but the foetus is still alive, the uterus is the size expected from the dates and the os is closed.
Threatened miscarriage
NB. Only 25% go on to miscarry
What is this type of miscarriage?
Bleeding is usually heavy. Although the the foetus may be alive, the os is open.
Inevitable miscarriage (miscarriage is about to occur)
What type of miscarriage is this?
Some foetal parts have been passed but the os is usually open.
Incomplete miscarriage
What type of miscarriage is this?
All foetal tissue has been passed. Bleeding has diminished, the uterus is no longer enlarged and the cervical os is closed.
Complete miscarriage
What type of miscarriage is this?
The foetus has not developed or died in utero, but this is not recognised until the bleeding occurs or USS is performed. The uterus is smaller than expected for dates and the os is closed.
Missed miscarriage
What three main tests are carried out for investigating recurrent miscarriage?
1) antiphospholipid antibody screen
2) karyotyping of both parents
3) pelvic USS (or hysterosalpingogram HSG)
Which four groups of patients are at high risk of developing pre-eclampsia?
1) HTN in previous pregnancies
2) CKD
3) autoimmune disorders such as SLE/antiphospholipid syndrome
4) type 1 or 2 DM
What is the main indication for Clomiphene?
To induce ovulation in patients with anovulatory infertility
What is the main indications for Danazol?
Derivative of ethisterone
Used to treat endometriosis and fibrocystic breast disease
Contraindicated in pregnancy as it causes virilisation of female foetuses
When are women screened for anaemia in pregnancy?
Booking visit and again at 28 weeks
What are the NICE limits for treating anaemia in pregnancy with oral iron therapy?
Booking visit less than 110g/l
28 weeks less than 105g/l
Which antibiotics are safe during breastfeeding? (3)
And which are not? (4)
Safe - penicillins, cephalosporins, trimethoprim
Avoid - ciprofloxacin, tetracycline, chloramphenicol, sulphonamides
What is IUGR and what is it associated with?
IUGR - intrauterine growth restriction where a foetus fails to meet its ‘growth potential’
Associated with pre-eclampsia and still birth
What is abnormal umbilical artery Doppler used for?
To look for an indication of placental insufficiency in a foetus that is SFD (small for dates). Increased pulsatility or resistance suggests resistance in the placental circulation.
How should placental insufficiency be managed?
Increased resistance - USS assessment and dopplers weekly
Absent or reversed end-diastolic flow - monitoring daily. The resistance is so high the blood is being forced backwards in diastole
Name four differences in presentation of placental Abruption vs placenta Praevia
Abruption - painful, dark bleeding (may not bleed), tender hard uterus, normal USS
Praevia - painless, profuse red blood, rarely tender, low placenta on USS
Risk factors for shoulder dystocia?
Foetal macrosomia
High maternal BMI
DM
Prolonged labour
What is a McRoberts manoeuvre?
Used for shoulder dystocia. Flexion and abduction of the maternal hips, bringing the thighs towards her abdomen. Thought to allow the maternal pelvic symphysis to rotate, as well as flatten the maternal sacrum
What are the three stages of labour?
1) from the onset of true labour to when the cervix is fully dilated
2) from full dilation to delivery
3) from delivery of the foetus to when the placenta and membranes have been completely delivered
What is the definition of Puerperal Pyrexia?
A temperature >38 degrees in the first 14 days following delivery
Name three causes of Puerperal Pyrexia?
Endometritis UTI Wound infections (perianal tears and Caesarean section) Mastitis VTE
What is the management for Peurperal Pyrexia from ?endometritis?
Admit to hospital for IV clindamycin and gentamycin until afebrile for >24hrs
When should Anti-D be given for Rhesus negative mothers?
At 28 weeks
After any bleeding or potentially sensitising event
After delivery if neonate is Rhesus positive
