Overview
HELLP syndrome is a severe complication of pregnancy characterized by Hemolysis, Elevated Liver enzymes, and Low Platelets, often overlapping with preeclampsia 14. It poses significant risks to both maternal and fetal health, necessitating prompt diagnosis and management 34.Diagnosis
Key Criteria: Hemolysis (elevated LDH, low haptoglobin), elevated liver enzymes (AST, ALT), and thrombocytopenia (platelet count <150,000/μL) 4.
Recommended Tests: Complete blood count, liver function tests, coagulation profile, urinalysis, and often imaging or monitoring for organ dysfunction 4.
Grading: Not explicitly detailed in abstracts, but clinical severity often guides management decisions 4.Management
First-Line Treatments: Urgent delivery if gestational age allows; correction of coagulopathy with fresh frozen plasma and platelets 4.
Adjunctive Treatments: Plasma exchange shown to be effective in refractory cases 2.
Specific Interventions: Management of organ dysfunction (e.g., ECMO for respiratory failure) and surgical interventions for complications like bowel ischemia 1.Special Populations
Pregnancy: HELLP syndrome often necessitates preterm delivery, especially if gestational age is advanced 34.
Comorbidities: Presence of severe thrombocytopenia and organ dysfunction complicates anesthetic choices and perioperative care 4.Key Recommendations
Urgent Delivery: Deliver the fetus as soon as possible if gestational age permits to mitigate maternal risks 4 (Evidence: Strong).
Preoperative Preparation: Ensure extensive preoperative correction of coagulopathy and hemodynamic stabilization with fresh frozen plasma and platelets 4 (Evidence: Strong).
Consider Plasma Exchange: For patients unresponsive to conventional therapy, plasma exchange may be considered as an adjunctive treatment 2 (Evidence: Moderate).References
