Pre-eclampsia Flashcards
Pre-eclampsia
High blood pressure during pregnancy that may be a precursor to a woman developing eclampsia and other complications
Pre-eclampsia triad
New-onset HTN
Proteinuria
Oedema
Definition
New onset BP >140/90 after 20 weeks of pregnancy and 1 or more of
- proteinuria
- other organ involvement: renal insufficiency, liver, neurological, haematological, uteroplacental dysfunction
Potential consequences
Eclampsia
Fetal complications
Liver involvement (elevated transaminases)
Haemorrhage (placental abruption, infra-abdominal, intra-cerebral)
Cardiac failure
Features of severe pre-eclampsia
HTN >160/110
Proteinuria
Headache
Visual disturbance
Papilloedema
RUQ/ epigastric pain
Hyperreflexia
Platelet count <100x10^6, abnormal liver enzymes or HELLP syndrome
High risk factors
Hypertensive disease in a previous pregnancy
CKD
Autoimmune disease (SLE, antiphospholipid syndrome)
T1/T2DM
Chronic HTN
Moderate risk factors
First pregnancy
Age >40
Pregnancy interval >10 years
BMI >35
Family history of pre-eclampsia
Multiple pregnancy
Reducing risk
Women with >1 high risk or >2 moderate risk factors
75-150mg aspirin daily from 12 weeks gestation
Initial management
Emergency secondary care assessment for any woman in whom pre-eclampsia is suspected
Women with BP?160/110 likely to be admitted
Further management
Oral labetalol (nifedipine or hydralazine can be used)
Delivery of baby is most important and definitive management
