Obs and Gynae Flashcards
Define Pre-eclampsia
New onset Hypertension (>140/80mmHg) after week 20 of pregnancy + either proteinurea or evidence of maternal organ dysfunction
What proteinuria findings are required for a pre-eclampsia diagnosis?
Either;
Urine Protein:creatinine ratio >30mmol/L
or
Albumin:creatinine ratio >8mmol/L
What types of maternal organ dysfunction are required for a diagnosis of pre-eclampsia?
Kidney - Renal dysfunction
Liver - Liver dysfunction (raised ATP/AAT)
Brain - Neurological dysfunction (stroke, blurred vision, ect)
Blood - Haematological disease (DIC, Thrombocytopenia, haemolysis)
Uterus - Uterine dysfunction - still birth, abnormal uterine artery doppler
Give some symptoms of pre-eclampsia (5)
Severe headache
Vomiting
Severe pain below ribs
Vision problems - Blurry/flashing lights
Sudden onset swelling of hands, feet or face
What is the target BP for pre-eclamptic patients?
135/85mmHg
What prophylactic management is given to pre-eclamptic patients? And what criteria must they fulfull?
Aspirin (75-150mg) from week 12 to birth.
Criteria;
x1 High risk factor OR >1 moderate risk factor
Give 5 high risk factors for pre-eclampsia
Previous hypertensive disease during pregnancy
Chronic kidney disease
Diabetes
Autoimmune disease - SLE/Antiphospholipid syndrome
Chronic hypertension
What are the 1st, 2nd and 3rd line therapies for chronic hypertension in pregnancy?
1st - Labetalol
2nd - Nifedipine
3rd - Methyl-dopa
What antihypertensive treatments are contraindicated in pregnancy? (5)
ACEi
ARBs
Statins
Thiazides
Thiazide diruetics
Give 6 moderate risk factors for pre-eclampsia
Nulliparus
Age >40
BMI >35
>10 year gap between pregnancies
Family history of hypertensive disease during pregnancy
Multi-fetal pregnancy
Define uterine fibroid
A benign tumour of the uterine myometrium
What are uterine fibroids composed of and what is their transverse appearance?
Whorled appearance.
Composed of smooth muscle cells and fibrous connective tissue
Describe the 3 types of uterine fibroid
Intermural - Restricted to myometrium
Submucosal - Involves endometrium, may bulge into uterine cavity
Subserosal - Bulges outside of uterus (may press on surrounding organs)
What is the name of the opening between the fallopian tubes and the uterine cavity?
Tubal Ostia
Give symptoms of uterine fibroids (3)
Heavy (sometimespainful) menses (>7 days bleeding)
Pressure symptoms;
- Rectum (constipation)
- Bladder (frequency)
- Ureter (hydronephrosis - flank pain)
Subfertility
- Submucosal can block tubal ostia
- Subserosal can inhibit implantation
Give a complication of uterine fibroids
Degenerations;
Red degenerations - Decreased blood flow - Presents with uterine pain and tenderness
Hyaline or cystic degenerations - fluid filled.
Investigations for uterine fibroid diagnosis (2)
Transvaginal Ultrasound. MRI if US intolerated
FBC - anaemia
Give some treatment options for uterine fibroids.
Monitor - Monitor size and growth (if asymptomatic)
Medical - GnRH agonist- Leuprorelin
Surgical - Hysteroscopic myomectomy (preserves fertility)
- Uterine artery embolisation (doesn’t preserve fertility)
- Hysterectomy
For the treatment of uterine fibroids, why would uterine artery embolization be favoured over a hysteroscopic myomectomy?
Favoured in high risk patients;
- Obese
- Chronic Hypertension
- Diabetes
How does Leuprorelin work and what are it’s main side effects?
GnRH agonist. Induces a temporary menopausal state by inhibiting the production of oestrogen.
Main side effects; osteoporosis, hot flushes, depression
What testing should be offered to rule out pre-eclampsia between 20 and 35 weeks in women with chronic hypertension?
Placental Growth Factor (PIGF) testing
What 3 clinical features must be present for diagnosis of hyperemesis gravidarum?
5% pre-pregnancy weight loss
Dehydration
Electrolyte imbalance
What electrolyte imbalances are commonly seen in hyperemesis gravidarum?
Hyponatraemia and Hypochloraemia
Give 5 clinical features of hyperemesis gravidarum
5% pre-pregnancy weight loss
Dehydration
Electrolyte imbalance (hyponatraemia/hypochloremia)
Ketosis
Hypovolemia
