What is the treatment for HELLP (Hemolysis, Elevated Liver enzymes, and Low Platelet count) syndrome?

Treatment for HELLP Syndrome

Deliver the patient immediately if HELLP syndrome occurs at or beyond 32-34 weeks gestation, or if maternal or fetal conditions deteriorate at any gestational age—this is the definitive treatment. 1

Initial Stabilization and Assessment

Upon diagnosis of HELLP syndrome, begin immediate stabilization:

• Control blood pressure aggressively using IV magnesium sulfate or hydralazine, targeting BP <160/105 mmHg to prevent complications including intracranial hemorrhage 1, 2
• Insert a urinary catheter for hourly urine output monitoring to assess renal function 1, 2
• Obtain comprehensive laboratory workup including platelet count, hemoglobin/hematocrit, peripheral blood smear for schistocytes, liver function tests (AST, ALT, LDH), coagulation profile (PT/PTT, fibrinogen, fibrin degradation products), and renal function tests (creatinine, urea, uric acid) 1
• Perform chest X-ray to exclude pulmonary edema and ECG 1
• Consider central venous catheter placement in critically ill patients for precise fluid management 1

Blood Product Transfusion Thresholds

**Transfuse platelets if count is <50,000/mm³, particularly if cesarean delivery is planned** 1, 2. In the setting of intracranial hemorrhage, target platelet count >80,000/mm³ 3.

• Transfuse whole blood or packed red blood cells if hemoglobin is <10 g/dL 1, 2
• Monitor coagulation parameters closely, as DIC can complicate HELLP syndrome 1

Definitive Treatment: Timing and Mode of Delivery

Immediate Delivery Indications

Proceed with immediate delivery if any of the following are present 1:

• Gestational age ≥32-34 weeks
• Worsening preeclampsia despite treatment
• Deteriorating hepatic or renal function
• Severe thrombocytopenia (platelets <50,000/mm³ or rapidly declining)
• Evidence of fetal distress
• Evidence of fetal lung maturity

Conservative Management (<34 weeks)

Conservative management for ≥48 hours may be considered only in highly selected cases <34 weeks gestation with stable maternal and fetal status 4. However, this approach is controversial and requires:

• Continuous intensive monitoring in a level 3 facility with maternal and neonatal ICU capabilities 5
• Administration of a single course of corticosteroids for fetal lung maturation: either betamethasone 12 mg IM every 24 hours for 2 doses, or dexamethasone 6 mg IM every 12 hours for 4 doses 4
• Immediate delivery if maternal condition worsens or fetal distress develops 4

Mode of Delivery

• Vaginal delivery is preferable if cervical conditions are favorable 4, 5
• Cesarean section rates are high (61.5-76%) due to obstetric indications including unfavorable cervix and fetal distress 1
• If cervical ripening is needed, it is reasonable to induce ripening followed by labor induction 4

Anesthetic Considerations

If general anesthesia is required for cesarean delivery:

• Use propofol for induction (minimal hepatic/renal metabolism) 1
• Consider rapid sequence induction with suxamethonium for airway management 1
• Regional anesthesia may be contraindicated if platelets <50,000-70,000/mm³ due to bleeding risk

Critical Postpartum Management (First 48 Hours)

The HELLP syndrome typically peaks 24 hours after delivery, requiring intensive monitoring for at least 48 hours postpartum 4, 6.

Blood Pressure Control

• Continue magnesium sulfate infusion for 24-48 hours postpartum for seizure prophylaxis and neuroprotection 2, 3
• For severe hypertension (≥160/110 mmHg), use IV labetalol or nicardipine as first-line agents 3
• Transition to oral antihypertensives (labetalol, long-acting nifedipine, or methyldopa) once BP stabilizes, targeting systolic <140-160 mmHg and diastolic ~85 mmHg 3

Fluid Management Strategy

Maintain strict fluid balance to avoid pulmonary edema—typically 80-100 mL/hour maintenance 2, 3. This is a critical pitfall: avoid aggressive fluid resuscitation that might reflexively be given to other critically ill patients, as this significantly increases pulmonary edema and cerebral edema risk 2, 3.

Laboratory Monitoring

• Perform serial complete blood counts every 6-12 hours initially to monitor platelets and hemoglobin 3
• Monitor liver function tests (AST, ALT, LDH) and renal function tests regularly 2
• LDH and platelet count are the two best tests to monitor disease progression 6

Complication Surveillance

Monitor vigilantly for:

• Hepatic hematoma or rupture: Perform abdominal ultrasound if right upper quadrant pain, epigastric pain, or right shoulder pain develops 2, 3
• Pulmonary edema: Monitor oxygen saturation, respiratory rate, and consider chest X-ray if respiratory symptoms develop 1, 2
• Renal failure: Monitor urine output hourly and creatinine levels 1, 2
• Eclamptic seizures: Continue magnesium sulfate prophylaxis 2
• Intracranial hemorrhage: Maintain strict BP control, especially if severe thrombocytopenia present 3

Important Caveats and Pitfalls

Do NOT give corticosteroids to improve maternal outcomes in HELLP syndrome—the American College of Obstetricians and Gynecologists advises against this practice despite historical use 2, 3. While corticosteroids for fetal lung maturation before 34 weeks are appropriate, high-dose maternal treatment and repeated doses should be avoided due to lack of proven maternal benefit and potential long-term adverse fetal effects 4, 7.

• Delayed diagnosis is common as symptoms may mimic acute cholecystitis, drug reactions, or idiopathic thrombocytopenia 1, 2
• Monitor for hypoglycemia during management 1, 2
• Maternal mortality rate is 3-5% even with optimal care, highlighting the severity of this condition 1, 3

Long-Term Counseling

• Counsel regarding increased recurrence risk in future pregnancies (up to 25%) 3
• Consider aspirin prophylaxis starting before 16 weeks gestation in future pregnancies 2, 3
