2

Pre-eclampsia

Htn + proteinuria +- oedema
Hyperreflexia, vomiting, hepatic tenderness, oliguria

3

Eclampsia

Pre-eclampsia + generalised convulsions

4

Classification of pre-eclampsia

Mild: bp> 140/90, proteinuria >0.3g/24hrs
Moderate: diastolic bp 100-110, proteinuria
Severe: >160 systolic, >110 diastolic

Resting bp, 2 readings 6 hours apart

5

Risk factors for pre eclampsia

1st pregnancy
Obesity, DM
FHx, Extremes of mat age
Pre-existing htn
Congenital thrombophilia, anti phospholipid syndrome
SLE, renal disease
Multip preg, hydatiform mole, hydrops fetalis

6

Blood pressure control

Antihypertensives for systolic >160, diastolic > 110
They limit the risk of vascular damage due to uncontrolled htn
Continue for 3/12 post partum
CCB: nifedipine
Alpha + beta blocker: labetalol in acute setting

7

Nifedipine

CCB + vasodilator
SE: flushing, headache, ankle swelling,
