Management of HELLP Syndrome
Deliver the patient promptly after stabilizing blood pressure and correcting coagulopathy—HELLP syndrome only resolves after delivery, and delaying definitive treatment increases maternal mortality risk. 1, 2
Initial Stabilization and Diagnosis
Immediate Actions
- Start IV magnesium sulfate immediately for seizure prophylaxis in all patients with HELLP syndrome and severe hypertension 2
- Control blood pressure urgently if ≥160/90 mmHg using IV hydralazine or labetalol 1, 2
- Transfer to ICU or high-dependency unit for continuous monitoring of blood pressure, oxygen saturation, ECG, and central venous pressure 2
- Insert urinary catheter for hourly output monitoring (oliguria <400 mL/24h indicates severe disease) 1, 2
Essential Laboratory Workup
Obtain the following tests immediately to confirm diagnosis and assess severity 1:
- Complete blood count with peripheral smear (platelet count <100,000/mm³ indicates active HELLP) 2
- Liver function tests: AST, ALT, LDH, total bilirubin 2
- Coagulation profile: PT, PTT, fibrinogen, fibrin degradation products 1
- Renal function: creatinine, urea, uric acid 1
- Urinalysis for proteinuria 1
Critical Imaging
- Perform abdominal ultrasound or CT immediately if patient has right upper quadrant or epigastric pain (65% of symptomatic HELLP patients have this presentation) to rule out subcapsular hematoma or hepatic rupture 2
- Obtain chest X-ray to exclude pulmonary edema 1
Blood Product Management
Platelet Transfusion Thresholds
- Transfuse platelets if count <50,000/mm³, especially before cesarean section 1, 2
- Strongly consider transfusion at higher platelet levels given increased bleeding risk 2
- The degree of thrombocytopenia directly correlates with liver dysfunction severity and predicts adverse maternal outcomes 2
Red Blood Cell Transfusion
Definitive Treatment: Delivery
Indications for Immediate Delivery
Proceed with delivery when any of the following are present 1:
- Worsening pre-eclampsia or HELLP syndrome
- Deteriorating hepatic or renal function
- Severe thrombocytopenia (especially <50,000/mm³)
- Gestational age ≥32-34 weeks
- Evidence of fetal distress
- Evidence of fetal lung maturity
- Hepatic rupture or subcapsular hematoma 2
Mode of Delivery
- Expect high cesarean section rates (61.5-76%) due to obstetric indications 1, 2
- Do not delay delivery waiting for laboratory values to normalize—maternal mortality is 3.4% with delayed intervention 2
Anesthetic Considerations
Regional vs. General Anesthesia
- Avoid regional anesthesia (epidural/spinal) if platelets <100,000/mm³ due to epidural hematoma risk 2
- Spinal anesthesia is first choice for cesarean section if only moderate, non-progressive thrombocytopenia exists 4
General Anesthesia Technique (if required)
- Use rapid sequence induction with suxamethonium for airway management 1
- Select drugs with minimal hepatic/renal metabolism—propofol is recommended 1
- Control hypertensive response to intubation aggressively to prevent cerebral complications 4
- Anticipate difficult airway and have advanced airway equipment ready 4
Post-Delivery Management
Intensive Monitoring Period
- Continue magnesium sulfate for 24 hours after delivery 3
- Maintain strict fluid balance for 24 hours post-delivery to avoid pulmonary edema—avoid aggressive fluid resuscitation 3
- Monitor laboratory values every 6-12 hours for at least 24-48 hours postpartum (30% of HELLP cases occur or worsen postpartum) 2
Blood Pressure Control
- Continue antihypertensives: oral labetalol, nifedipine, or methyldopa for non-severe hypertension 3
- Use IV labetalol or hydralazine for severe hypertension in monitored setting 3
Surveillance for Complications
Watch for the following life-threatening complications 1, 3:
- Hepatic hemorrhage or hematoma (monitor for abdominal pain, epigastric pain, right shoulder pain)
- Renal failure (monitor hourly urine output and creatinine)
- Pulmonary edema (avoid fluid overload)
- Hemorrhage (monitor hemoglobin and coagulation parameters)
- DIC (monitor fibrinogen and platelet count)
- Hypoglycemia (check glucose levels) 1, 3
Peak Disease Activity
- HELLP syndrome intensity peaks 24 hours after delivery—maintain highest vigilance during this period 5
Critical Pitfalls to Avoid
- Never use corticosteroids to improve maternal HELLP outcomes—they are ineffective for maternal disease 2, 3
- Do not miss delayed diagnosis: symptoms mimic acute cholecystitis, drug reactions, idiopathic thrombocytopenia, appendicitis 1, 6
- Do not perform invasive procedures (central lines, arterial lines) without correcting coagulopathy first 4
- Markedly reduced platelet count (<20×10⁹/L) correlates with higher hepatic hemorrhage risk—escalate monitoring 3
