Pre-eclampsia with Severe Features / Severe Pre-eclampsia
Admission & discharge
Admission/discharge guidance checked 2026-10-18 against the linked sources. This is a clinical checklist for an individual decision, not an automatic discharge order.
When admission or continued hospital care is needed
- Admit for severe/persistent hypertension, seizure or neurological symptoms, pulmonary oedema, renal/liver/platelet deterioration, significant pain or fetal compromise.
- Eclampsia/HELLP or organ-support needs require appropriate high-dependency/critical-care monitoring, with transfer after initial stabilisation when necessary.
When clinic, day care or home care may be suitable
- Antenatal outpatient care is a specialist decision only when maternal/fetal assessment and reliable surveillance support it; recent eclampsia or HELLP is not a routine outpatient pathway.
Before going home
- Postnatal NICE transfer criteria: no pre-eclampsia symptoms, BP ≤150/100 mmHg with or without treatment, and blood results stable or improving; all criteria must be met.
- Following eclampsia/HELLP, complete indicated seizure prophylaxis/monitoring and document neurological, respiratory, urine-output and blood-test recovery before considering home care. Critical-care step-down and discharge home are separate decisions.
Discharge medicines and treatment changes
- Continue the selected oral antihypertensive. Stop methyldopa within 2 days after birth; document replacement and review.
- The prescriber should consider reduction below 140/90 and reduce below 130/80 mmHg under NICE; provide an individual written adjustment plan. Magnesium loading/infusions are inpatient treatment, not take-home medication.
Medicine doses — use only when indicated
Use the medicines selected for this patient. Listed alternatives are not instructions to prescribe all of them together. Confirm the actual remaining course, pregnancy/postnatal context and monitoring plan.
One selected oral BP option; do not prescribe every alternative together.
- Indication: Maintenance hypertension during pregnancy/postpartum
- BP/heart rate, postural symptoms; neonatal glucose/heart-rate observation after late-pregnancy exposure
Alternative/adjunct only within the documented BP plan.
- Indication: Maintenance hypertension in pregnancy/postpartum
- BP, headache, flushing, oedema and pulse
Postpartum only when prescribed, with renal function/potassium monitoring.
- Indication: After birth only; NICE recommends enalapril with maternal renal-function and potassium monitoring
- Renal / hepatic: Renal impairment requires a lower initial dose and adjustment from the product renal table, not the unadjusted 5 mg starter.
- NICE NG133 supplies the postpartum choice. Breastfeeding requires extra caution with premature/very young infants; use a suitable alternative when clinically indicated.
- BP, symptoms, creatinine/eGFR and potassium before and after initiation/dose changes; infant feeding, alertness and urine output if breastfeeding
Tests, pending results and their reviewer
- Review platelet count, transaminases and creatinine at 48–72 hours after birth/critical-care step-down; abnormal results need a repeat plan until recovery.
- At 6–8 weeks check urine protein; persistent proteinuria (1+ or more) needs a 3-month renal review and referral if kidney function is abnormal.
Home care and counselling
- Provide the BP schedule, named reviewer, medicine list and explicit severe-symptom instructions. Discuss recurrence, future-pregnancy planning and long-term cardiovascular risk.
Follow-up: when and what to review
| When | Action / responsible service |
|---|---|
If on antihypertensives: every 1–2 days for up to 2 weeks after transfer | NICE BP surveillance until off treatment with no hypertension; adapt intensity to findings. |
If not on antihypertensives: day 3–5 after birth | Check BP; repeat on alternate days if abnormal. |
2 weeks if still on treatment; 6–8 weeks for all | Review medicines, BP, recovery and urine protein; arrange renal follow-up when indicated. |
Return urgently
- Seizure, severe/persistent headache, visual disturbance, epigastric pain, dyspnoea, chest pain or severe BP: return immediately; postpartum onset can occur after discharge.
Treatment
① Immediate stabilization — first minutes
③ First-line treatment & drug regimens
- Eclampsia: stop seizures and prevent recurrence
- Check patellar reflexes, respiratory rate and hourly urine output; monitor BP, pulse and consciousness
- Withhold magnesium for absent reflexes, respiratory rate <12/min or urine <100 mL in 4 h; obtain serum magnesium and senior review
- Stop magnesium and support ventilation for toxicity; give the calcium-gluconate antidote shown below
- Eclampsia: alternative when a reliable infusion pump and monitoring are available
- Maintenance concentration and pump rate are calculated from the prescribed 1 g/hour; independently check the preparation.
- Check patellar reflexes, respiratory rate and hourly urine output; monitor BP, pulse and consciousness
- Withhold magnesium for absent reflexes, respiratory rate <12/min or urine <100 mL in 4 h; obtain serum magnesium and senior review
- Stop magnesium and support ventilation for toxicity; give the calcium-gluconate antidote shown below
- Persistent severe hypertension in pregnancy or postpartum (systolic ≥160 OR diastolic ≥110 mmHg)
- Check BP and pulse before and after each acute dose; fetal monitoring when appropriate
- Persistent severe BP despite the initial sequence requires senior/anaesthetic review, a different agent and HDU-level monitoring; avoid uncontrolled stacking
- Alternative for acute severe hypertension
- Renal / hepatic: Reduce doses with renal/hepatic impairment
- Check BP and pulse before and after each acute dose; fetal monitoring when appropriate
- Persistent severe BP despite the initial sequence requires senior/anaesthetic review, a different agent and HDU-level monitoring; avoid uncontrolled stacking
- Acute severe hypertension when oral dosing is appropriate
- NHM CEmONC contains an internal discrepancy: its prose caps the initial course at 30 mg, while the adjacent flowchart shows 10 mg then 20 mg then 20 mg. The app uses the 30 mg prose limit with prompt escalation; confirm the locally approved sequence.
- Check BP and pulse before and after each acute dose; fetal monitoring when appropriate
- Persistent severe BP despite the initial sequence requires senior/anaesthetic review, a different agent and HDU-level monitoring; avoid uncontrolled stacking
- If MgSO4 unavailable: diazepam 10 mg IV for seizure only (inferior — arrange supply urgently)
- Nicardipine/esmolol infusions in ICU settings where available
④ Drug treatment detail (3 agents)
- Indication: Antidote for clinically significant magnesium toxicity
- Continuous ECG/heart rate; respiratory status, reflexes and injection site; serum calcium/magnesium where available
- Indication: Imminent preterm birth within the guideline gestational window; do not delay urgent maternal/fetal delivery
- NICE offers at 24+0–33+6 weeks, considers 34+0–35+6; individual discussion at 22+0–23+6. Repeat: <34 weeks, prior course >7 days ago and very high risk of birth in 48 h.
- Glucose monitoring and an insulin-adjustment plan in diabetes; assess infection and timing of birth
- Indication: Alternative fetal-lung-maturation course when appropriate
- Maternal glucose, infection assessment and birth timing; diabetes team plan
Definitive treatment
- DELIVERY IS THE DEFINITIVE TREATMENT
- ≥34 weeks: deliver after maternal stabilisation (FOGSI: severe PE delivered after 34 completed weeks)
- <34 weeks: expectant management ONLY if mother stable AND fetus viable AND facility has HDU/ICU + NICU 24/7 — otherwise deliver after steroids (48 h benefit window) if stable enough
- 24–33+6 weeks: individualised (no trial evidence base — FOGSI explicitly notes this)
- ≤24 weeks: immediate delivery generally better option (FOGSI)
- Indications for IMMEDIATE birth regardless of gestation: uncontrollable BP, eclampsia, pulmonary oedema, DIC, abruptio, non-reassuring fetal state, ruptured membranes/labour, HELLP with multiorgan dysfunction
Monitoring
| Domain | Expectant-management schedule (intensive) |
|---|---|
BP | Hourly (continuous arterial line in ICU if unstable) |
Neuro obs + reflexes | Hourly |
Labs (platelets/LFT/creatinine) | Minimum daily; q12h if deteriorating |
MgSO4 toxicity | Before each dose: reflexes, RR ≥12, UO ≥25 mL/h |
Fluid balance | Hourly urine; daily weight |
Fetus | Daily CTG; UA Doppler ± DV 2–3×/wk; growth q1–2 wk |
Response assessment
- BP in target band on stable regimen
- Labs plateau/improving
- No seizure activity
- Reassuring fetal parameters
Treatment failure
- Rising BP needs → add second class agent
- Lab deterioration or symptom evolution → abandon expectancy, deliver
- Seizure despite MgSO4 → reload per eclampsia protocol (additional 2 g IV if reflexes absent logic — see eclampsia module)
Second-line treatment
- ICU-level vasodilator infusions (nicardipine) where available
- Plasmapheresis rarely for catastrophic HELLP/TTP confusion — haematology consult
Rescue treatment
Intracranial haemorrhage: emergent CT, neurosurgical referral, keep SBP <160 then 130–150, correct coagulopathy, deliver once salvageable. Pulmonary oedema: CPAP where available, frusemide 40–80 mg IV, stop fluids, expedite birth.
Procedure / surgery
- Anaesthesia: regional preferred if platelets >70–75×10⁹/L with normal coagulation (local policy); GA if coagulopathy/urgent — careful intubation BP surge attenuation (labetalol/remifentanil)
- Surgical team aware of friable tissues/bleeding tendency
- Active third-stage management mandatory
Escalation
- HDU mandatory during acute control
- ICU triggers: ventilatory support, vasopressors, dialysis, post-craniotomy, refractory seizures
- Tertiary transfer BEFORE deterioration if local capability lacking and gestation allows expectancy
⑮ Complications & their management
Eclampsia
Dedicated algorithm (hdp-eclampsia/emergency hub)
HELLP
hdp-hellp module
Renal failure
Nephrology; dialysis if AEIOU indications
Liver rupture/infarction
Haemodynamic collapse + RUQ → CT angio, interventional radiology embolisation, surgery; massive transfusion
Post-treatment care
- HDU/ward observation ≥24–48 h postpartum (risk persists)
- MgSO4 continues 24 h after birth/last seizure
- Thromboprophylaxis once haemostasis secure
- Debrief + documentation; neonatal follow-up arranged
- Postpartum review schedule as for PE
Diagnosis & assessment
- Impending/actual eclamptic seizure
- Uncontrolled BP despite two agents
- Platelet fall + LFT rise (evolving HELLP)
- Oliguria <25 mL/h despite fluids
- Abnormal CTG/stillbirth risk
- Stroke signs
- Pulmonary oedema
Definition: Pre-eclampsia with ANY of: SBP ≥160/DBP ≥110 (confirmed), thrombocytopenia <100×10⁹/L, AST/ALT >×2 ULN with severe persistent RUQ/epigastric pain, renal insufficiency (creatinine >97 µmol/L or doubling), pulmonary oedema, new-onset cerebral/visual disturbances (FOGSI severe PE definition: BP >160/110 ± premonitory symptoms ± abnormal labs, or ≥140/90 WITH symptoms/lab abnormality).
Initial assessment
- Call for senior obstetrician + anaesthetist; allocate 1:1 nursing
- Left-lateral tilt if supine; continuous SpO₂, BP q10–15 min initially
- Send full panel INCLUDING coagulation + group & save/crossmatch
- Start MgSO4 if neurological signs/symptoms or imminent birth <30 wks (neuroprotection overlap)
- Control BP to SBP 130–150/DBP 80–90 (rapid drops risk placental hypoperfusion)
- Strict fluid balance; restrict maintenance fluids (pulmonary oedema risk)
Investigations
| Test | Looking for |
|---|---|
Coagulation profile + fibrinogen | DIC before regional anaesthesia/procedures |
Group & save / crossmatch | Operative readiness |
Serum urate, LDH, blood film | Haemolysis (HELLP evolution) |
CT head if focal deficit/coma/atypical presentation | ICH vs eclampsia vs other |

Principles & follow-up
Management principles
Guideline conflict
India NHM CEmONC, chapter 4 — prose
Acute oral nifedipine: 10 mg, reassess at 20 minutes, repeat 10–20 mg; stated initial-course maximum 30 mg.
Same NHM chapter — adjacent flowchart
The flowchart shows 10 mg, then 20 mg, then another 20 mg at 20-minute reassessments, implying 50 mg.
Population/setting difference: These refer to the same severe-pregnancy-hypertension setting; this is an internal document discrepancy, not a demonstrated population difference.
Practical India consideration: Confirm the sequence formally approved in the treating unit. Extended-release maintenance tablets are a separate regimen.
Reason: This avoids silently combining incompatible limits or prolonging oral loading in uncontrolled severe hypertension.
Guideline conflict
India NHM CEmONC, chapter 4 — prose
20 mg, then 40 mg, then 80 mg at 10-minute reassessments; further dosing may reach a cumulative 300 mg.
Same NHM chapter — adjacent flowchart
Stops the displayed 20 → 40 → 80 mg sequence at a stated 140 mg maximum.
Population/setting difference: Same emergency setting; the flowchart and prose show different stopping points.
Practical India consideration: Use the approved local sequence and track every previous IV dose. Persistent severe BP needs senior/anaesthetic involvement.
Reason: A cumulative ceiling is not an instruction to continue dosing without reassessing treatment failure and contraindications.
