Investigations for preclampsia and eclampsia
- Urinalysis:
- 24 hour urinary protein and creatinine clearance to asses renal
function - Full blood count -low platelet
- PCV, Hb level - Increases due ot haemoconcentration
- Clotting profile - Whole blood clotting time, PTTK and PT are al prolonged
- Liver Function Test -elevated liver
enzymes due to hepatocyte necrosis - Serum urea, electrolyte and creatinine compromise.

Definitive treatment of preclampsia
*definitive treatment of per-
eclampsia as wel as preventing its progression to eclampsia is delivery of baby and placenta.
Treatment depends on:
- Gestational age
- Severity of disease
Treatment of mild preclampsia
Mild
- At term, control BP and deliver
- Before term, control BP and manage conservatively till pregnancy si term (37 weeks).
Treatment of severe preclampsia
Severe
At term, control BP and expedite
delivery
- Before term, control BP and expedite delivery
Treatment of eclampsia
At any GA, control BP, abort seizure and deliver via the fastest and
safest route (to both mother and baby).
Antihypertensives used:
*Hydralazine is most commonly used at 5-10mg Iv slowly, repeated every 30 minutes it diastolic BP = 110mmHg.
Other hypertensive medications used in O and G
Oral methyldopa - drug of choice for hypertension ni pregnancy for long term use.
- Labetalol
- Nifedipine
Abortion of seizure (anticonvulsants) which drug
Magnesium sulphate (MgSO4) si the drug of choice. Different protocols of use are available.
MgSO4 toxicity manifest as;
- Respiratory rate < 21 cycles per minute.
- Loss of knee jerk reflex
- Oliguria -<25mls/hr
- Slurred speech and cardiac arrest.
How is magnesium sulphate toxicity managed
*Toxicity is managed using 10ml of 10% Calcium Gluconate given intravenously over 10mins (rule of 10)
