Treatment of HELLP Syndrome
Immediate delivery is the only definitive treatment for HELLP syndrome, regardless of gestational age, with timing based on maternal condition and fetal status. 1
Diagnosis and Initial Management
HELLP syndrome is a severe form of preeclampsia characterized by:
- Hemolysis
- Elevated Liver enzymes
- Low Platelet count
Initial laboratory assessment should include:
- Complete blood count with peripheral smear
- Liver function tests (AST, ALT)
- Lactate dehydrogenase (LDH)
- Serum haptoglobin
- Coagulation studies (especially if platelets <100,000/mm³)
- Renal function tests
- Urinalysis for proteinuria 1, 2
Treatment Algorithm
Step 1: Immediate Hospitalization and Stabilization
- Admit to a monitored setting with maternal-fetal surveillance
- Monitor vital signs and fetal well-being
- Obtain baseline laboratory values
- Assess for complications (abdominal pain, neurological symptoms)
Step 2: Blood Pressure Management
- Target blood pressure: systolic 110-140 mmHg, diastolic 85 mmHg 1
- First-line medications:
- IV labetalol: 10-20 mg initially, then 20-80 mg every 10-30 minutes (max 220 mg)
- IV hydralazine: 5-10 mg every 15-30 minutes
- IV nicardipine: Start at 5 mg/h, increase by 2.5 mg/h every 5-15 minutes (max 15 mg/h)
- Oral nifedipine may be used if IV options unavailable 1
Step 3: Seizure Prophylaxis
- Magnesium sulfate is indicated for all HELLP patients:
- Loading dose: 4-5g IV over 15-20 minutes
- Maintenance: 1-2g/hour by continuous IV infusion
- Continue for at least 24 hours postpartum 1
Step 4: Delivery Planning
- Delivery is the definitive treatment
- Mode of delivery considerations:
Step 5: Platelet Management
- If platelet count <50,000/mm³ or active bleeding:
- Platelet transfusion before delivery or invasive procedures
- Consider fresh frozen plasma if coagulopathy present 4
Step 6: Postpartum Care
- Continue magnesium sulfate for at least 24 hours postpartum
- Monitor laboratory values (HELLP typically peaks 24 hours after delivery)
- Continue antihypertensive therapy as needed
- Close monitoring for complications (DIC, renal failure, pulmonary edema) 1, 2
Special Considerations
Anesthetic Management
- Neuroaxial anesthesia (spinal) is preferred if platelets >70,000-80,000/mm³ and stable
- General anesthesia may be required if:
- Severe thrombocytopenia (<50,000/mm³)
- Coagulopathy present
- Neurological symptoms present 4
Severe Cases
- Consider intensive care unit admission
- Invasive monitoring may be necessary
- In rare cases of extended atypical HELLP not responding to delivery, plasma exchange has been used 2
Follow-up Care
- Review at 3 months postpartum to ensure:
- Resolution of hypertension
- Normalization of laboratory values
- Resolution of proteinuria
- Counsel regarding increased risk in future pregnancies
- Consider aspirin prophylaxis (150 mg nightly) before 16 weeks' gestation in future pregnancies 1
Common Pitfalls and Caveats
- Delayed diagnosis and treatment can lead to significant maternal and fetal morbidity and mortality 3
- HELLP can present with incomplete features (partial HELLP) but should be treated with the same urgency 5, 6
- HELLP can develop postpartum (typically within 48 hours) and requires the same management approach 5
- The condition typically worsens before improving after delivery, with peak intensity at 24 hours postpartum 2
- Avoid NSAIDs for postpartum analgesia due to potential renal effects 1
