HELLP Syndrome

IN REVIEWv3🇮🇳 India-firstPENDING CLINICAL VERIFICATION
Haemolysis + Elevated Liver enzymes + Low Platelets — a variant of severe pre-eclampsia that may present WITHOUT marked hypertension. Birth is definitive; transfuse selectively; beware misdiagnosis as gastritis/hepatitis.

Admission & discharge ↓

Reviewer note: Medication regimens and dependent emergency instructions checked 17 October 2026. These targeted checks do not certify every statement in the module. Admission/discharge guidance checked 18 October 2026. This adds a scoped clinical synthesis and does not certify every statement in the module.

Admission & discharge

Care setting: Hospital assessment; severe disease needs admission and possible critical care

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.
  • Platelet, haemolysis/liver and renal trends must support recovery; delivery does not immediately resolve every HELLP complication.

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.

Labetalol oralMSFchecked
DoseStart 100 mg twice daily; increase by 100–200 mg increments according to BP; higher daily doses divided three times daily
RouteOral
FrequencyTwice daily initially; three divided doses if higher doses needed
DurationContinue while clinically required; titrate down rather than stop abruptly, with a postpartum review plan
Preparation100 mg or 200 mg tablets; prescribe the strength, dose and administration times
Max dose2400 mg/day
  • Indication: Maintenance hypertension during pregnancy/postpartum
Monitoring
  • BP/heart rate, postural symptoms; neonatal glucose/heart-rate observation after late-pregnancy exposure
Contraindications: Asthma, heart block, marked bradycardia, decompensated heart failure

Alternative/adjunct only within the documented BP plan.

Nifedipine extended releaseGovernment of India, MoHFW / NHMchecked
DoseStart sustained-release nifedipine 10 mg twice daily; titrate according to BP and the exact release formulation
RouteOral extended release
FrequencyTwice daily for the cited sustained-release regimen
DurationWhile hypertension persists; reassess after birth and reduce when BP allows
PreparationUse the specified sustained-release tablet, swallowed intact. Other extended-release products may use different strengths/schedules; do not interchange them or use them for acute oral loading.
Max dose80 mg/day for the NHM CEmONC sustained-release regimen
  • Indication: Maintenance hypertension in pregnancy/postpartum
Monitoring
  • BP, headache, flushing, oedema and pulse
Contraindications: Maternal hypotension or significant cardiac outflow obstruction

Postpartum only when prescribed, with renal function/potassium monitoring.

Enalapril — postpartum hypertensionMilpharm / emcchecked
DoseStart 5 mg once daily; use a lower supervised initial dose if volume depleted or renally impaired; titrate to BP response
RouteOral
FrequencyOnce daily initially
DurationReview BP and dose after birth; reduce/stop as hypertension resolves or continue for persistent hypertension after medical review
Preparation5 mg tablet swallowed with water, with or without food. Correct volume depletion; check creatinine and potassium before starting
Max dose40 mg/day in the product label; usual maintenance 20 mg/day, not an automatic postpartum target
  • 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.
Monitoring
  • BP, symptoms, creatinine/eGFR and potassium before and after initiation/dose changes; infant feeding, alertness and urine output if breastfeeding
Contraindications: Pregnancy, prior ACE-inhibitor angioedema, significant hyperkalaemia; avoid starting in unresolved AKI or severe volume depletion

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

WhenAction / 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
  • Admit HDU; IV access; crossmatch
  • Correct hypovolaemia cautiously (pulmonary oedema risk)
  • MgSO4 per severe-PE policy
  • Control BP ≥160/110
③ First-line treatment & drug regimens
  • STEROIDS if <34+6 wks and birth planned/likely (standard antenatal course; some units extend to 35+6 with caution)
  • Plan birth: CLASS II HELLP (platelets ≤100) with stable mother ≥34 wks → deliver; <34 wks stable → short expectancy (24–48 h steroids) ONLY in tertiary centre
  • CLASS I HELLP (platelets ≤50) or any instability → DELIVER regardless of gestation
④ Drug treatment detail (6 agents)
Magnesium sulfate — IV/IM regimenMSFchecked
Dose4 g IV loading, then 5 g deep IM into EACH buttock (10 g IM total); maintenance 5 g IM into alternate buttocks
RouteIV loading + deep IM
FrequencyLoading once; maintenance every 4 hours
DurationContinue until 24 hours after birth OR the last seizure, whichever is later
PreparationUsing 50% (500 mg/mL): 4 g = 8 mL; dilute in 100 mL sodium chloride 0.9% and infuse over 15–20 min. Each 5 g IM dose = 10 mL of 50% solution. Check the actual ampoule strength.

  • Stop magnesium and support ventilation for toxicity; give the calcium-gluconate antidote shown below
Contraindications: Myasthenia gravis, heart block or magnesium toxicity · Renal impairment or oliguria requires reduced/withheld maintenance and more frequent assessment
Magnesium sulfate — IV regimenMSFchecked
Dose4 g IV loading over 15–20 min, then 1 g/hour
RouteIV infusion
FrequencyOne loading dose, then continuous infusion
Duration24 hours after birth or last seizure, whichever is later
Preparation50% solution: withdraw 8 mL (4 g) into 100 mL sodium chloride 0.9% for loading; for maintenance make 20 g up to a FINAL 100 mL (200 mg/mL), run at 5 mL/hour by labelled pump
Max doseUse ONE IV or IV/IM protocol; stop/adjust for toxicity or renal dysfunction
  • Indication: 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.
Monitoring
  • 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

Dose1 g (10 mL of 10% solution) slowly
RouteIV
FrequencyInitial antidote dose; reassess breathing, ECG and calcium before further dosing
DurationEmergency reversal; stop magnesium and support the airway concurrently
Preparation10% = 100 mg/mL; 10 mL contains 1 g calcium gluconate, NOT 1 g elemental calcium. Give over at least 5 min through a patent IV line; do not mix with other drugs
Max doseNo automatic repeated-dose course; further calcium requires monitored reassessment
  • Indication: Antidote for clinically significant magnesium toxicity
Monitoring
  • Continuous ECG/heart rate; respiratory status, reflexes and injection site; serum calcium/magnesium where available
Contraindications: Extravasation can cause tissue injury; take special care with digoxin · Do not confuse calcium gluconate with calcium chloride
Dose20 mg over 2 min; reassess at 10 min, then 40 mg; further 80 mg doses at 10-min intervals if severe BP persists
RouteIV bolus
Frequency10-minute reassessment and dose sequence
DurationAcute control, then change to an appropriate oral regimen
Preparation5 mg/mL stock: 20 mg = 4 mL, 40 mg = 8 mL, 80 mg = 16 mL. Give each dose slowly, record cumulative dose and check the stock strength
Max dose300 mg cumulative in the cited Indian CEmONC regimen; seek escalation before continuing beyond it
  • Indication: Persistent severe hypertension in pregnancy or postpartum (systolic ≥160 OR diastolic ≥110 mmHg)
Monitoring
  • 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
Contraindications: Asthma, bradycardia/heart block or decompensated heart failure
Hydralazine IVMSFchecked
Dose5 mg slowly IV over 2–4 min; reassess for 20 min and repeat 5 mg if still severe
RouteIV
FrequencyEvery 20 min if required after reassessment

Max dose20 mg cumulative in this MSF bolus regimen
  • Indication: Alternative for acute severe hypertension
  • Renal / hepatic: Reduce doses with renal/hepatic impairment
Monitoring
  • 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
Contraindications: Marked hypotension, severe tachycardia or coronary ischaemia; use cautiously in cardiac disease
Nifedipine immediate releaseGovernment of India, MoHFW / NHMchecked
Dose10 mg swallowed; reassess at 20 min and give another 10–20 mg if still severe
RouteOral, swallowed
FrequencyReassess after each 20-minute interval; switch/escalate when the initial-course limit is reached
DurationAcute sequence, followed by senior review and a separately prescribed maintenance regimen
PreparationUse immediate-release oral tablets/capsules; swallow whole. NEVER sublingual administration; do not use an extended-release tablet as a rapid-loading substitute
Max dose30 mg cumulative for the NHM prose-based initial course; seek senior selection of another agent rather than continuing oral loading
  • Indication: 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.
Monitoring
  • 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
Contraindications: Hypotension, significant aortic stenosis or acute cardiac compromise · Magnesium co-administration requires close respiratory/neuromuscular and BP monitoring; follow the named unit protocol

Definitive treatment

Birth (usually within 24–48 h of onset) — most mothers improve dramatically postpartum; nadir of labs occurs 24–48 h AFTER delivery — expect transient worsening.

q8–12h peri-delivery period
Urine output
Hourly in HDU phase
RUQ pain/shoulder tip
Continuous — rupture warning
Fetal CTG
Continuous intrapartum
Treatment failure
  • Persistent multiorgan failure >72 h postpartum → reconsider diagnosis (TTP/aHUS!) — haematology + plasma exchange
  • Subcapsular haematoma → IR embolisation/surgery
Procedure / surgery
  • Regional anaesthesia CONTRAINDICATED if platelets <70–75 or coagulopathy (GA with aspiration precautions)
  • Caesarean for obstetric indications — not automatic; induction reasonable with Class II stable
  • Cell-salvage consideration; anticipate PPH
Escalation
  • ICU: multiorgan dysfunction, ventilatory support, dialysis
  • Interventional radiology: hepatic artery embolisation for rupture
  • Haematology: diagnostic uncertainty/plasma exchange
⑮ Complications & their management
DIC

Component therapy per ratio protocol; treat underlying (birth); monitor fibrinogen

Hepatic rupture/infarction

Haemodynamic resuscitation + CT angio + embolisation/laparotomy; massive transfusion activation

AKI

Usually prerenal/AKI of PE — fluid balance, dialysis if indicated

Neonatal thrombocytopenia

Paediatric review at birth (rare serious neonatal disease)

Post-treatment care
  • Labs normalize over 48–96 h postpartum — verify before discharge
  • Contraception: avoid COCP until platelets/LFTs normal & BP controlled
  • Recurrence risk 3–19%; aspirin next pregnancy from 12 wks
  • Renal/hepatic function recheck at 6 weeks

Diagnosis & assessment

Red flags:
  • RUQ pain mistaken for "gastritis" in third trimester
  • Platelets falling fast
  • Spontaneous bleeding/bruising
  • Jaundice + dark urine
  • Fetal compromise

Definition: Microangiopathic haemolysis (schistocytes, LDH >600 IU/L, bilirubin ≥1.2 mg/dL), AST ≥70 IU/L, platelets <100×10⁹/L (Tennessee classification) occurring in pregnancy/peripartum, usually with hypertensive disease.

Initial assessment

  1. Peripheral smear for schistocytes
  2. LDH, indirect bilirubin, haptoglobin
  3. Platelet trend q6–12h
  4. Coagulation incl. fibrinogen (DIC overlap)
  5. Exclude: TTP (ADAMTS13 if available), AFLP (glucose, INR, ammonia), gastroenteritis, hepatitis serology where picture ambiguous

Investigations

TestLooking for
Smear + retics + LDH
MAHA confirmation
Serial platelets
Rate of fall; nadir typically 24–48 h POSTPARTUM
Glucose + INR
Differentiate acute fatty liver of pregnancy (hypoglycaemia + profound INR rise favour AFLP)
CT/MRI abdomen if RUQ severe
Subcapsular haematoma/hepatic rupture

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.

App default: Use the prose-based 30 mg initial limit with prompt senior reassessment and selection of another agent if severe BP persists.
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.

App default: The card records the prose ceiling of 300 mg; persistent severe BP after the initial 140 mg sequence requires senior reassessment before additional doses or another agent.
Reason: A cumulative ceiling is not an instruction to continue dosing without reassessing treatment failure and contraindications.
