Intravascular hemolysis associated with hydrocarbon poisoning.

Hydrocarbon ingestion may result in serious complications such as adult respiratory distress syndrome, encephalopathy, and seizures. Hematologic disorders have appeared to be rare complications of hydrocarbon toxicity. After encountering a case complicated by severe intravascular hemolysis, we reviewed the hospital records of all patients admitted to our pediatric intensive care unit (PICU) because of complicated hydrocarbon poisoning. Three of the 12 PICU patients identified developed intravascular hemolysis, and one developed disseminated intravascular coagulation. One patient required transfusion, but all recovered without sequelae. Intravascular hemolysis may be a more frequent complication of hydrocarbon poisoning than previously recognized.
