Pre-eclampsia + grand mal seizure not attributable to other causes. Can occur:
Antepartum (before delivery) — 50%
Intrapartum (during labour) — 25%
Postpartum (after delivery) — 25% — up to 4 weeks
Key fact: Up to 30% of eclampsia occurs WITHOUT prior hypertension or proteinuria — always suspect in seizures of unknown origin in women of childbearing age.
Severe Features (ANY one qualifies)
Systolic BP ≥160 mmHg or diastolic ≥110 mmHg (confirmed ×2, 15 min apart)
Thrombocytopenia <100,000/μL
Renal insufficiency — creatinine >97 μmol/L (or doubling from baseline)
Impaired liver function — AST/ALT >2× upper limit normal
Persistent RUQ or epigastric pain unresponsive to analgesia
Equivocal — repeat in 6 hours; consider delivery if ≥37 weeks
Score ≤4 / 10
Abnormal — urgent delivery planning regardless of gestation
✓ Antepartum Assessment Checklist
⚠ Treatment Thresholds
UK / GCC Practice — Treat if Sustained:
Systolic ≥150 mmHg, OR
Diastolic ≥100 mmHg
ACUTE Treatment — ACOG / Emergency Threshold:
Systolic ≥160 mmHg, OR
Diastolic ≥110 mmHg
Treat within 30–60 minutes of confirmed reading
Target BP Range:
Aim for 140–155 / 90–105 mmHg. Avoid aggressive reduction — rapid BP fall can cause fetal distress via placental hypoperfusion. Do not target normal BP levels.
💊 First-Line Antihypertensive Agents
LABETALOL (Alpha & Beta Blocker) — IV First-Line for Acute Severe Hypertension
IV Bolus Protocol
50 mg IV over 1 minute
Repeat at 20-minute intervals PRN
Maximum cumulative dose: 200 mg
Check BP every 5 minutes after each dose
IV Infusion (Alternative)
200 mg in 200 mL (1 mg/mL)
Start at 20 mg/hr; titrate up
Maximum 160 mg/hr
Convert to oral when stable
Oral Dosing (Maintenance)
100–200 mg twice daily; increase as needed to max 800 mg/day
Headache common side effect — does NOT indicate treatment failure
CAUTION — Nifedipine + Magnesium Sulphate: Combination may cause severe hypotension and neuromuscular blockade. Use with extreme caution; monitor BP and reflexes closely if concurrent.
METHYLDOPA — Oral (Chronic / Maintenance)
250–500 mg three times daily; maximum 3 g/day
Long safety record in pregnancy
Sedation and dry mouth common
NOT for acute severe hypertension — onset too slow
Avoid postpartum — associated with postnatal depression
Given to women with severe pre-eclampsia features to prevent first seizure. Particularly in GCC hospitals with high-risk populations.
Mechanism: Competes with calcium at NMDA receptors; reduces cerebral vasospasm; anticonvulsant effect. Also causes peripheral vasodilation — minor antihypertensive effect (NOT a primary antihypertensive).
💊 Dosing Protocol
LOADING DOSE
4 g IV over 20 minutes
4 g = 20 mL of 20% MgSO4, OR 40 mL of 10% MgSO4
Diluted in 100 mL Normal Saline or 5% Dextrose
Infuse via infusion pump — never bolus
Monitor BP and reflexes throughout loading
MAINTENANCE DOSE
1–2 g/hr IV infusion
Typically 1 g/hr in standard protocol
Continue for 24 hours postpartum (or 24hrs post-seizure if eclampsia)
Some GCC units continue 48hrs postpartum — check local protocol
Hypotension = check concurrent nifedipine; reduce rate; IV fluid bolus with caution
ANTIDOTE — Keep at Bedside at ALL Times
Calcium Gluconate 10% — 10 mL IV over 10 minutes
Dose: 1 g (10 mL of 10% calcium gluconate) given slowly IV
Repeat if respiratory depression persists
Have pre-drawn syringe or ampoule + 10 mL syringe at bedside
Do NOT use calcium chloride (risk of tissue necrosis if extravasated)
Continue oxygen; support ventilation; call anaesthetics if no improvement
⛈ Eclamptic Seizure Management
EMERGENCY — Follow ABCDE Approach
Immediate Actions (First 2–3 Minutes)
Call for HELP — emergency buzzer / dial hospital emergency
Note seizure start time
Turn patient to left lateral position — airway, aortocaval decompression
Protect from injury — do NOT restrain forcefully
Airway: suction if accessible; insert airway if feasible when mouth opens
High-flow oxygen 15 L/min via non-rebreathe mask
Do NOT give anything oral
Pharmacological Intervention
If NOT on MgSO4: Give loading dose 4 g IV over 20 min
If already on MgSO4 and seizure recurs: further 2–4 g IV over 5–10 min
If seizure continues >5 minutes or recurs: consider IV diazepam 10 mg or lorazepam 4 mg — anaesthetic team
Check serum Mg level post-seizure
Ensure bladder catheter in situ — monitor UO
Postpartum consideration: If seizure occurs in postnatal ward or community — call emergency services, left lateral, MgSO4 if available — transfer to obstetric HDU.
✓ Magnesium Protocol Checklist
⏰ Timing of Delivery
Gestation & Situation
Recommendation
Considerations
≥37 weeks — any pre-eclampsia
Recommend delivery
Risk of deterioration outweighs prematurity risk at term
≥34 weeks — severe features
Deliver after stabilisation
Steroids if given time; MgSO4 for neuroprotection <32 weeks
34–37 weeks — severe features
Deliver after maternal stabilisation
Steroids may be offered; neonatal team involvement
<34 weeks — severe features, stable
Steroids first if feasible (48 hrs); then delivery
Betamethasone 12 mg IM × 2 doses 24hrs apart; may manage conservatively in tertiary centre
<34 weeks — uncontrolled BP / maternal deterioration
Expedite delivery regardless of gestation
Maternal safety takes priority; inform neonatal team
Eclampsia (any gestation)
Stabilise first, then deliver
Do not rush to emergency CS during active seizure; stabilise, then plan delivery mode
🕐 Intrapartum Care
Monitoring During Labour
Continuous electronic fetal monitoring (EFM) — mandatory in pre-eclampsia
BP every 15–30 minutes (or continuous arterial line in severe cases)
Fluid balance with catheter — hourly urine output
MgSO4 infusion continued throughout labour
Antihypertensives as required to maintain target BP
Anaesthetic team review in advance
Anaesthesia & Analgesia
Epidural anaesthesia is BENEFICIAL in pre-eclampsia — reduces catecholamine surge, lowers BP
Ensure platelet count adequate before epidural (>80,000/μL most centres; >100K preferred)
Check coagulation if platelets trending down
Spinal anaesthesia for CS if platelets adequate
General anaesthesia risk: intubation hypertensive response — inform anaesthetist
Oxytocin Caution
Oxytocin bolus can cause transient hypotension and tachycardia — use slow infusion titration rather than IV bolus where possible. Standard augmentation protocols apply.
ERGOMETRINE — CONTRAINDICATED
Ergometrine (ergot alkaloids) cause severe vasoconstriction and can precipitate catastrophic hypertension — DO NOT use Syntometrine. Use Syntocinon (oxytocin) only for third stage.
⚠ Postpartum Pre-Eclampsia — Critical Period
Pre-eclampsia can WORSEN or first present POSTPARTUM — up to 4 weeks after delivery
The first 48–72 hours postpartum are the highest risk period for:
Eclamptic seizures (25% of all eclampsia is postpartum)
Pulmonary oedema — fluid mobilisation from third space
HELLP syndrome onset or worsening
Hypertensive crisis
Postnatal Monitoring Requirements
BP at least 4-hourly for 24 hours post-delivery
Continue MgSO4 for 24 hours postpartum
Repeat bloods (FBC, LFTs, U&E) at 24 and 48 hours
Strict fluid balance — risk of pulmonary oedema during fluid shift
Watch for new symptoms: headache, visual disturbance, epigastric pain
Postnatal Antihypertensives
Continue antihypertensive therapy postnatally
Labetalol — safe in breastfeeding; first choice
Nifedipine MR — safe in breastfeeding; second choice
Avoid methyldopa — associated with postnatal depression
ACEi/ARBs still contraindicated if breastfeeding (enalapril is cautiously used in some guidelines — local protocol applies)
Discharge Criteria & Follow-Up
Criterion
Safe for Discharge
Blood pressure
BP stable <150/100 on oral antihypertensives for ≥24 hours
Bloods
Platelets rising, LFTs improving, creatinine stable or improving
Symptoms
No severe symptoms (headache, visual, epigastric resolved)
Fluid balance
Adequate urine output, no signs of pulmonary oedema
Home BP plan
Home BP cuff provided; frequency of monitoring documented

Estimated pre-eclampsia prevalence in GCC pregnancies (vs 2–5% globally)
Leading
Pre-eclampsia/eclampsia remains a leading cause of maternal mortality in several GCC countries
30–40%
GCC countries with rising obesity rates — major pre-eclampsia risk driver
Contributing Factors to Higher GCC Rates:
High rates of obesity and gestational diabetes
High IVF utilisation — multiple gestations
Late maternal age at first pregnancy
Consanguineous marriages — thrombophilia risk
Rapid urbanisation and sedentary lifestyle
Vitamin D deficiency (paradoxically high despite sun exposure — clothing practices)
Limited antenatal care attendance in some subpopulations
Cultural barriers to early presentation

⚡ HELLP Syndrome — GCC Considerations
Liver Rupture in HELLP — Rare but Reported in GCC
Subcapsular liver haematoma and hepatic rupture are life-threatening complications of HELLP syndrome. GCC case reports document this complication, particularly in patients presenting late.
Warning Signs — Escalate Urgently
Severe, worsening RUQ or epigastric pain
Sudden onset of diffuse abdominal pain
Haemodynamic instability unexplained by other cause
Rapidly falling haematocrit
CT scan — subcapsular haematoma or free fluid
Management Principles
Urgent obstetric, surgical, and anaesthetic review
Massive transfusion protocol
Angioembolisation by interventional radiology if available
Surgical exploration if rupture
Transfer to tertiary centre if needed
👥 Cultural Considerations in GCC Obstetric Nursing
Bed Rest — Cultural vs Evidence
Bed rest for pre-eclampsia is culturally expected and commonly prescribed in some GCC hospitals. Evidence does NOT support bed rest as improving outcomes — and may increase DVT risk. Nurses should educate without dismissing cultural beliefs while following evidence-based protocols.
Family-Centred Communication
In GCC culture, family involvement in care decisions is significant. Male family members may be primary communicators. Ensure the patient herself remains central to informed consent while respecting family dynamics. Use professional interpreters — avoid relying on family members for critical medical interpretation.
Aspirin Prophylaxis Adherence
Low-dose aspirin (75–150 mg daily from 12 weeks) is underutilised in GCC high-risk patients. Nurse education and midwife-led review clinics can improve adherence. Dispel misconceptions about aspirin harm in pregnancy.
Postpartum Follow-Up Gaps
Cultural disengagement from postnatal care is a patient safety risk. Pre-eclampsia can first present or worsen postpartum. Discharge education must be in Arabic with written instructions. Provide emergency contact numbers. Home BP monitoring devices should be issued where possible.
