Hemorrhagic shock and encephalopathy syndrome.
Hemorrhagic shock and encephalopathy syndrome (HSES) is a devastating symptom complex that affects previously healthy infants and is associated with significant mortality and neurologic morbidity. The syndrome was first reported less than ten years ago, and there continues to be debate regarding whether HSES actually represents a distinct clinical entity or instead is a manifestation of heat illness, occult sepsis or endotoxic shock, or perhaps toxic ingestion. Nevertheless, the signs and symptoms described as HSES present in a typical fashion in the emergency department with sudden onset of shock, encephalopathy, seizures, and coagulopathy. Even with the initiation of intensive support in the ED, the outcome is probably dismal. We describe a case of HSES and review the presentation, proposed etiologies, and management of this catastrophic illness.
